CHAPTER 1. GENERAL INFORMATION AND OPERATING INSTRUCTIONS
Section 1. General Description
1. GENERAL
The Modular Deicer provides mobile deicing and anti–icing for aircraft of all sizes. It is designed to be easilyadaptable to each customer’s specific needs.
The unit can be adapted for use on various chassis used world wide. This adaptability includes a variety of tankcapacities and deice and anti–ice configurations. The various configurations are capable of handling a widevariety of fluids currently in use for deicing and anti–icing. The unit can also be adapted to use many different typesof power modules using various types of fuels.
The controls for operating the Modular Deicer systems, including the power module, are located on a control panelin the truck cab.
An intercom is included in the Modular Deicer for communication between the cab and the basket.
The Modular Deicer has built–in safety features to prevent damage to the unit as well as the operator. All safetyprecautions and warnings should be followed as prescribed in this manual as well as on the truck itself.
2. HYDRAULIC SYSTEM
A. PUMP (Ref. Figure 1 )
The hydraulic pump is axial piston pressure compensated, load sensing and is used for allsystems. The pressure compensator feature is designed to protect the system against the failureof other components. In normal operation, the pressure system will never be high enough tocause the pump to compensate. This pump receives oil from the reservoir and delivers it to aclosed valve at the inlet of each system where it maintains pressure while pumping only enoughoil to replace leakage
B. Load Sensing System
Each individual hydraulic system is fitted with an opening, either fixed or variable, which is sizedto provide the desired flow at a specific pressure drop across the opening. When a system isactuated and the valve is opened, the pump maintains a specific pressure above the operatingpressure and provides the correct flow through the opening. The integrated circuit manifoldassembly is located on the backside of the pedestal (Ref. Figure 2). Located in the bottom rightside of the integrated circuit manifold assembly is a two position, two way solenoid valve thatconnects the load sense port of the boom valve to the tank while de–energized. This immediatelystops the pump flow when the power is turned off or the emergency stop switch is pushed.

C. Main Relief Valve
A relief valve is located in the body of the integrated circuit manifold for protection in the eventthe pump compensator fails. This relief valve is set at a specified pressure above thecompensator setting and should never relieve.
D. Boom Raise and Lower (Ref. Figure 3)
The boom raise and lower cylinder is controlled by oil from a valve on the boom valve assemblymounted on the forward left side of the deicer. The electrical signal to the valve coils for raise andlower speed is controlled by the joystick in the operator’s compartment
A relief valve is teed into the ground line going to the cap end of the boom cylinder to prevent liftingan overloaded operator’s compartment. A relief valve is also teed into the line going to theopposite (rod)end of the boom cylinder to limit the pressure while lowering the boom
There is a counter balance valve at the cap end port of the boom cylinder to prevent the boomfrom lowering in the event of the failure of a hose or directional valve. When the cylinder is beingretracted hydraulically, the counter balance valve is piloted open.
The boom raise and lower valve has a manually operated elevation lever which can be used tooverride the valve and lower the operator in case of failure of a coil or the main pump.
E. Boom Rotation
The boom is rotated by a geroller type hydraulic motor through a gear reduction. Flow for thismotor is supplied from a valve on the boom valve assembly. The rotation speed (flow rate) iscontrolled by the electrical signal supplied to the valve coils from the joystick in the operator’scompartment.
A dual cross over relief assembly is mounted in the left end of the boom valve assembly. Thisrelief assembly is for the protection of the boom rotation motor. This valve is equipped with amanually operated rotation lever for overriding the valve in the event of a coil failure

GENERAL INFORMATION
F. Deicing Delivery Pump
The diaphragm pump that delivers deicing fluid is driven by a fixed displacement motor. Hydraulicfluid for this motor is supplied by a solenoid valve located at the left side of the integrated circuitmanifold assembly (Ref Figure 2). The flow rate to this motor is controlled by a flow control valvecartridge screwed into a sandwich valve directly under the solenoid valve. This flow control valveis adjustable by means of an allen head screw.
G. Anti–ice / Refiller
The diaphragm pump that delivers the optional anti–Ice fluid is driven by a fixed displacementmotor. Hydraulic fluid for this motor is supplied from a solenoid valve on the left end of theintegrated circuit manifold. The flow rate to this motor is controlled by a flow control valvecartridge screwed into a sandwich valve located on top of the manifold. This flow control valveis adjustable by means of an allen head screw. Pressure to the drive motor is regulated by apressure reducing valve cartridge located directly under the solenoid valve. This valve cartridgeprovides constant pressure Anti–Ice fluid to the nozzle independent of the flow rate. When thenozzle is closed, the hydraulic system maintains a constant static pressure at the nozzle
H. Blower Drive
The blower fan for the fluid heater is driven by a fixed displacement motor. Hydraulic fluid for lowspeed start up operation of the blower fan is supplied from a solenoid valve cartridge at theright–hand side of the integrated circuit manifold, near the pressure gauge. The speed of themotor is controlled by the flow control valve cartridge located at the lower right–hand corner ofthe front face of this same manifold. Hydraulic fluid for high speed operation of the blower fan issupplied from a solenoid valve cartridge at the top right–hand side of the integrated circuitmanifold. High speed operation of the motor is controlled by the flow control valve cartridgelocated at the left side of the low speed flow control valve cartridge.
I. Fluid Heater Fuel Pump Drive (optional)
The fuel pump for the diesel fired fluid heater is driven at a constant speed by a hydraulic motor.Hydraulic oil to drive the motor is supplied by a solenoid valve through a pressure compensatedflow control valve. These valves are located at the right side end of the integrated circuit manifold.Constant fuel pressure is maintained by a relief valve between the fuel pump and the burnernozzle.
J. Emergency Pump (Ref. Figure 1)
The Modular Deicer has an optional electrically powered hydraulic pump for use in anemergency, such as the failure of the engine or main pump while the operator is elevated in theoperator’s compartment. This pump can be used to rotate and lower the boom. A check valveprevents the emergency pump flow from flowing through the main pump in the event of a failure.
K. Heat Exchanger
Two oil to air heat exchangers are installed in the return to tank line of the hydraulic system toprevent the hydraulic oil from over heating. One heat exchanger is located under the hydraulicreservoir and the other is located under the heater module. The exchangers have electric motordriven fans to move air through the fins of the oil coolers. A temperature switch located insidethe hydraulic reservoir controls the fan motors.

SMD–1200 MODULAR DEICERAIRLINE EQUIPMENT
1–1Page 13Feb. 97
GENERAL INFORMATION
(1) Storage Reservoir
The storage reservoir comes in a variety of sizes for deicing fluid only or a combinationof deicing and optional anti–icing fluid. The reservoir is constructed of stainless steel toreduce maintenance and increase the life of the tank as well as protect sensitiveanti–icing fluids. Exterior man holes have been supplied for cleaning and maintenance.
(2) Pumping System
The deicing delivery pump is a two stage centrifugal or diaphragm pump used to circulatedeicing fluid through the heater. A second diaphragm pump then delivers the deicingfluid to the basket and ground reel hose. Plumbing from the reservoir to these pumpsincludes service valves, stainless plumbing, and high temperature hose.
(3) Fluid Heater
The heater is self controlled and regulating during operation and will automatically turnoff when the reservoir has reached deicing temperatures. The internal heating flame isfully enclosed allowing heating operations around aircraft. The heater will raise the fluidtemperature very quickly. The fluid is returned to the reservoir during heater operation,rapidly heating the stored deicing fluid.
(4) Aerial Platform
Boom movement is controlled by the basket joystick, optional cab controls, or the controllevers located at the ground control station (Ref. Figure 10). The optional cab boomcontrols will override the basket joystick and the ground control levers will override thebasket joystick and cab boom controls. Aircraft deicing can be accomplished using thebasket nozzle or the ground level hose reel nozzle.
B. Anti–icing Fluid System (Optional)
An anti–icing system may be installed for coating the aircraft skin immediately after deicingoperations to increase hold–over times.
(1) Storage Reservoir
When this system is installed, the main reservoir is partitioned off to contain theanti–icing fluid.
(2) Pumping System
An additional high volume anti–icing pump, associated plumbing, and special nozzle isused to dispense the anti–icing fluid. This fluid is not heated and can only be dispensedfrom the basket. The anti–icing pump transfers anti–icing fluid from the reservoir,increases the pressure to working levels, and transfers the fluid to the basket.
NOTE: There is no On–Off switch for the anti–icing pump. The anti–icing pump is activewhenever the auxiliary engine is running and sufficient fluid is available.

GENERAL INFORMATION
4. POWER MODULE AUXILIARY ENGINE OPERATION (REF. FIGURE 1)
A. Cab Control Box
All controls for starting and stopping the auxiliary engine are located on the cab control box. The cab control boxis mounted on a pedestal to the right of the drivers’ seat.
The cab control box controls/indicators are grouped according to function from bottom to top of the control boxin the order of the start sequence. For example, the auxiliary engine must be started prior to running the heater,therefore, auxiliary engine controls are on the bottom followed by heater controls on top.
B. Auxiliary Engine Controls
Auxiliary Engine controls consist of an “IGNITION SWITCH” and a “START ENABLE SWITCH.”
(1) START ENABLE SWITCH
This switch momentarily bypasses the engine shutdown system to facilitate startingwhile no oil pressure exists. This switch can be held during cold starting to allow theengine to warm up and develop sufficient oil pressure. Some options that are availablemodify this two position switch. “COLD START” is available on diesel engines. Thisoption changes the start enable switch to a three position switch.
(a) Center position is ”OFF.”
(b) Upper position is still the ”START ENABLE” position and is momentary.
(c) New Lower position is also momentary but, when held down, the glow plugheaters on the engine are energizing. This switch is generally held down forabout 30 seconds prior to starting.
For Ford gas engines, this lower position is for priming the carburetor prior tostarting. Selecting this position injects fuel into the carburetor.
Regardless of the version, this “START ENABLE” switch must be held in the “UP”position prior to starting the engine.
(2) IGNITION SWITCH
This switch is always a 3 position switch. The lowest position is ”OFF.”
The center position is the “ON” position. The emergency pump system and the gaugelights can be operated in this position. On a Ford gas engine, the ignition switch shouldremain in this position 3 seconds prior to starting.
The upper position on the ignition switch is the ”START” position and is a momentaryswitch.
NOTE: The ignition switch should always be placed in the ”OFF” position whenever the deiceris not in use to prevent draining the batteries.
SMD–1200 MODULAR DEICERAIRLINE EQUIPMENT

SECTION 2. OPERATION
(3) Auxiliary Engine Gauges
(a) Tachometer
The tachometer is located directly above the ignition and start enable switches.Engine speed is automatically controlled, with idle speed set for 1000 RPM andnormal operation set for a ”HI” throttle position of 2000RPM.
(b) Engine Condition Instruments
These instruments are located to the right of the tachometer and consist of 4gauges:
1) Coolant Temperature
2) Fuel Level
3) Oil Pressure
4) Voltmeter
(c) Warning Lights
There are 5 red warning lights on the cab control box associated with theauxiliary engine:
1) High Engine Temperature
2) Low Oil Pressure
3) High Hydraulic Oil Temperature
4) Low Fuel
5) Generator (No Out Put)
C. Auxiliary Engine Start Sequence
(1) Place ignition switch to the “ON” position.
(2) For cold weather start – Hold down ”START ENABLE” switch approximately30 secondsto preheat (diesel engine) or momentarily two or three times to prime (gas engine).
(3) Hold ”START ENABLE” switch ”UP”.
(4) While holding ”START ENABLE” switch ”UP”, push ignition switch to ”START”.

Feb. 97
GENERAL INFORMATION
(5) The engine is running when the low oil pressure light goes out and the tachometerindicates a steady RPM.
(6) Once the engine is running, release the ignition switch to its ”ON” position.
(7) The ”START ENABLE” switch can remain held in the ”UP” position until indicators showengine is up to speed (engine will idle at 1000 RPM).
The best indicators for a running auxiliary engine are:
1 – Tachometer – Steady RPM (1000 RPM for idle)2 – Generator Light – Out (Not Illuminated)3 – Low Oil Pressure Light – Out (Not Illuminated)
The oil pressure and voltmeter gauges can also be indicators that the engine isrunning. The oil pressure gauge should indicate in the green band and thevoltmeter should indicate in the green band at approximately 24 volts.
NOTE: Once engine is running, the starter will be electrically locked out from re–engaging.
NOTE: The tachometer will have a floating indicator when the ignition is turned off. Once theignition switch is pushed to ”ON”, the needle will go to zero.
D. Auxiliary Engine Shutdown
(1) Turn the heater and deicing fluid delivery pump off if they are operating. The engine willcontinue to run at 2000 RPM until purge cycle is completed (approximately threeminutes).
(2) Allow the engine to idle (1000 RPM) for approximately two minutes to properly cooldown.
(3) Turn the ignition switch off.
NOTE: The ignition switch should always be placed in the ”OFF” position whenever the deiceris not in use to prevent draining the batteries.
5. HEATER OPERATION
A. Control Functions
(1) The heater control consists of a 3 position, center off, momentary switch for starting andstopping the heater.
SMD–1200 MODULAR DEICERAIRLINE EQUIPMENT
1–2Page 9Feb. 97
SECTION 2. OPERATION
(2) Two indicator lights accompany the switch.
(a) The GREEN LIGHT directly above the switch indicates that the heater has beenenabled and the firing sequence has begun.
(b) The WHITE LIGHT above and to the right of the switch indicates that flame hasbeen established and the heater is operating.
(3) The two gauges to the left of the switch indicate fluid temperature at the heater inlet andheater outlet.
B. Heater Start Sequence
(1) After engine is running push HEATER SWITCH to “ON”.
The GREEN LIGHT should immediately illuminate. The switch can now be released andthe light should remain illuminated. This indicates that the firing sequence is under way.
(2) Engine RPM automatically increases to 2000 RPM. After approximately 30 seconds theWHITE LIGHT will illuminate and remain on, indicating that the flame has beenestablished and the heater is operating.
(3) Monitor the temperature gauges to determine fluid temperature.
NOTE: If the GREEN LIGHT does not illuminate, check tank temperature. If temperature isabove 180ºF (82ºC) the heater circuitry is disabled.
NOTE: If WHITE LIGHT does not illuminate, call for service.
C. Heater Cycle
(1) The heater will shut down automatically when the fluid temperature reaches 180º F (82ºC) (normally 20 to 30 minutes) and both the WHITE LIGHT and GREEN LIGHT willextinguish.
(2) After shut down, the heater fluid pump and air blower will continue to run for threeminutes to reduce the heater temperature and purge any fumes and unburned fuel thatmay remain after shut down. After this purge cycle is complete the engine will return toidle speed.
(3) Monitor the temperature gauges on the cab control panel or, if equipped,on the basketcontrol panel to determine fluid temperature. The heater will not restart automatically ifthe fluid temperature falls below acceptable levels. It will be necessary for the operatorto restart the heater if the fluid temperature is too low.

MAINTENANCE / TROUBLESHOOTING
2. FLUID SYSTEM DESCRIPTION
A. Deicing Fluid Delivery Pump
Located in the right hand side compartment, this pump circulates fluid through the heater andmaintains a constant system pressure. This pressure is regulated by the pump speed and thesystem relief valve located on the heater outlet manifold. The pump supplies sufficient flow of hotfluid to both the ground reel nozzle and the basket Deicing nozzle.
The Deicing pump is an iron bodied, two stage centrifugal pump incorporating a mechanical shaftfluid seal. The pump is supported by grease lubricated ball bearings and requires littlemaintenance. Power is supplied by an hydraulic motor attached to the pump shaft through a softcoupling. The pump speed is relatively constant and can be changed or adjusted with a flowcontrol valve located on the main hydraulic manifold.
B. Anti–Icing Delivery Pump
Located in the left hand side compartment. This pump will deliver anti–icing fluid to the basketnozzle on demand. This pump is set to a maximum flow rate of 15 (56.5 liters/min) to 30 gpm(113.5 liters/min) to reduce fluid damage during passage through the nozzle. Flow rate is variableup to the maximum setting and is controlled by the nozzle valve. A fully open nozzle isrecommended for anti–icing operations with the pump speed set to control a “NOT TO EXCEED”flow rate. The pump is an iron bodied radial design incorporating six diaphragm chambersoperating in a parallel flow path. Each chamber includes an inlet and outlet check valvecontrolling the flow direction through the pump. The diaphragms are operated by push rodsconnected to a cam on the drive shaft. This arrangement allows the pump to run either directionwithout affecting the direction of the fluid through the pump. Power is supplied by a hydraulicmotor attached to the back of the pump bracket and connected with a 3 – jaw soft coupling. Thepump “NOT TO EXCEED” flow rate of 15–30 gpm is controlled by the motor speed. The motorspeed can be changed by adjusting an hydraulic flow control valve located on the main hydraulicmanifold attached to the pedestal in the rear engine compartment. Optionally, this pump can beused to refill the anti–icing fluid reservoir as a suction refilling station. When used as a refillstation, additional hydraulic valves are supplied to allow a faster pump speed for refilling at upto 60 gpm. Additionally, a speed sensor can be added to this pump to supply a remote signalreadout to indicate the volume of anti–icing fluid delivered.
C. Anti–Icing Fluid Delivery Counters (optional)
The use of high volumetric efficiency fluid pumps allow a simple way of measuring nominal fluiddelivery. When installed, a simple high speed sensor is attached to a delivery pump and countspump revolutions. This data is sent to a counter head located at a remote location, usually thedriver’s compartment. The counter data is converted to US gallons or liters and displayed on adigital readout. The display unit includes a reset button for tracking a single aircraft deicingoperation or can be used for total fluid dispensed over any period required. When used inconjunction with a station refiller, the volume of fluid transferred can be tracked.

SECTION 1. SERVICING
D. Ground Reel & Nozzle
Located in the forward left side compartment, the reel supplies deicing fluid through a standard50 ft. (15.2 m) hose and nozzle. The nozzle is non–adjustable and incorporates a pistol grip withlever to open the internal valve. Delivery flow rate is controlled by the valve lever. When fullydepressed, it will deliver approximately 25 US gpm (113 liters/min) Others nozzles may beinstalled and usually operate in a similar fashion. A hand crank is supplied to assist in rewindingthe hose after use. The reel may include an optional electric motor to speed rewinding. Whenequipped with a motor, a switch is located ahead of the reel for actuation.
E. Deicing Nozzle (Basket)
A nozzle is supplied that allows the operator to dispense deicing fluid in any reasonable directionfrom the basket. It is normally a hand held pistol grip type with an open–close lever on top andequipped with a selector ring for different flow rate settings. The nozzle is connected to a hoseextending from the aerial boom allowing the operator to move freely. The deicing fluid flow rateis variable and controlled by a nozzle valve opening and ring setting, when fully open,approximately 60 US gpm (227 liters/min) is available. Various nozzles may be installed fordifferent situations, or they may be mounted on rigid plumbing (turret). A holster or receptacleis provided for hand held nozzles and includes a rubber hold down latch.
F. Anti–Icing Nozzle (Basket)
When an anti–icing system is installed, a small hand held nozzle is located in the basket. Thismay be an FMC 785 style gun with a pistol grip and a trigger controlled valve. This nozzle isconnected to a hose extending from the aerial boom and allows the operator to move freely. The785 nozzle allows a delivery rate up to 25 US gpm (113 liters/min). Other nozzles may be suppliedfor this operation and operate similarly. A fully open nozzle will generally reduce fluid damageduring anti–icing operations. A holster or receptacle is provided and includes a rubber hold downlatch.
G. Fluid Reservoir
This reservoir will hold a maximum of 1200 US gallons (4540) liters) combined deicing or deicingand anti–icing fluid. The tank is constructed from stainless steel with access covers for cleaning.The forward sections contain deicing fluid and the aft section will contain anti–icing fluid whenincluded. The tank outlet ports include gate valves for service and 1/4 turn ball valves for refilland drains. The forward compartment contains a sump for maximum fluid usability. A sidemounted port and valve is supplied for rapid draining of the deicing fluid and a similar valve issupplied for the aft anti–icing tank when appropriate.
H. Heater Inlet Manifold
Located in the right hand side compartment extending forward of the heater. This manifoldtransfers fluid from the deicing pump to the heater and contains several temperature switchesto monitor incoming fluid for heater operation. A pressure gauge and a temperature gauge isinstalled. An additional port is present for an optional remote temperature sender.

MAINTENANCE / TROUBLESHOOTING
I. Heater Outlet Manifold
Located at the rear of the heater under the burner assembly. This manifold contains a flow switch,pressure gauge, temperature gauge, temperature cycle switch and over temperature switch. Theflow switch monitors fluid flow through the heater and will not allow the heater to operate ifinsufficient flow is detected. The cycle switch modulates the burners to keep the outlettemperature as even as possible. The heater over temperature switch will turn the heater off ifthe outlet fluid becomes too hot. A manual reset button is supplied and the heater cannot berestarted until it has been reset. A system relief valve is attached to this manifold and regulatesthe Deicing system pressure.
J. Deicing Fluid Flow Switch & Timer
Located at the base of the pedestal and near the heater, this flow switch will monitor deicing fluiddelivery. If fluid flow is detected, the delivery pump will continue to run. If fluid flow stops, a timeris activated and will count down for two minutes after which the delivery pump will stop. If fluidflow is detected anytime during the two minute period, the timer will reset and wait for anotherno flow condition. If the pump stops, it can be restarted by actuating a switch in the basket.
K. Deicing Refill Stations For Suction Refilling
A deicing fluid refill station is installed just forward of the deicing pump located in the right sidecompartment. This station allows an external pressurized or non–pressurized fluid to be pumpedinto the deicing reservoir. A switch is located near the external hose connection to start the pumpfor suction refilling.
L. Anti–Icing Refill Station For Suction Refilling
An Anti–Icing refill station is installed on the anti–icing pump located in the left side compartment.This station allows an external pressurized or non–pressurized fluid to be pumped into theanti–icing reservoir. A lever is located on top of the pump manifolds to direct the fluid to thereservoir. A switch is located near the external hose connection to start the pump for sectionrefilling.
M. Deicing Pressure Fill Station
Located in the left side compartment, aft of the ground reel, this port normally serves as a rapiddrain for the deicing fluid. When quick connect type hose couplings are installed, the deicingreservoir can be filled from any pressurized source.
N. Fluid Thermal Relief Valve
A small relief valve is attached to the anti–icing pump. This valve relieves the fluid thermalpressure rise when the unit is not in operation.
O. Heater Safety Relief Valve
This valve is located in the heater inlet manifold and is for the explicit purpose of relieving a rapidpressure rise if other heater safety systems fail to operate. This valve is sometimes required bylocal or other safety regulations.
P. Pressure Gauges
A pressure gauge is located on the heater inlet manifold and on the heater outlet manifold. Thesegauges indicate system pressure at that point and are used for adjustment and service.

A. Flame Detection System ( Ref. Figure 1)
(1) Unplug relays 23CR and 24CR inside Heater Control Box.
(2) Start engine.
(3) Turn on heater. Green LED on flame detector module should come on. If not, checkwiring to flame detector (17CR, 8CR, 4TD etc.)
NOTE: During these tests it is important to remember that the module will only have power for50 seconds after heater is started. You may need to turn heater off / on again to getanother 50 seconds, if required.
(4) If 12V is present at wire #211 but green LED is not on, check module wiring hookup forcorrect polarity. Wire #211 must be on “+” and wire #1 must be on “–”.
(5) When green LED is on, connect voltmeter to flame detector module as follows: Red lead to TP–1 on module and black lead to ground (wire #1).
(6) Voltage at TP–1 should be 3.5V to 4.0VDC. If not, adjust with trimpot. Turn clockwise toincrease and counterclockwise to decrease.
(7) Turn heater off and move voltmeter red lead to TP–2 on module.
(8) Unscrew flame sensor from heater and point to a bright light source such as the sun orthe end of a bright flashlight.
(9) Turn heater back on again to get a full 50 seconds test. The voltage seen at TP–2 nowshould be greater than 4.5 volts and the red LED should be on. You will also see themisfire and premature–flame light come on at the heater box.
(10) If voltage is less than 4.5V,. check to make sure the sensor is seeing bright light. If voltageis still less than 4.5V, check sensor wiring.
(11) If voltage at TP–2 is at least 4.5V, the red LED is not on, and the voltage on TP–1 is 3.5Vto 4V, then change modules.

Figure 2DESCRIPTION OF MANOMETER
A manometer is nothing more than clear plastic tubing in a ”U” shape, filled about half way with water (sometimesthe water is dyed so it can be seen better.) The manometer can be connected to the port located on the heaterburner head directly across from the air switch. When a fan or blower is running, it will move the water in the tube.The distance between the water columns is a measure of pressure change within the heater (this is known as”inches [or millimeters] of water displaced” ). Thus, the manometer provides another means of measuring the airflow through the heater instead of using a tachometer to measure the speed of the fan or blower.
C. Fuel Pressure
