FCU PIPING PACKAGES • DESCRIPTIONS


GENERAL NOTES

• Control valves are piped normally closed to the coil as standard.

• 3-way valves are installed as mixing valves as standard.

• Transformer option required with 24 volt control valves unless field furnished.

• Memory stop serves as a balancing valve and is provided as an attachment to one of the ball stop iso-lation valves in the piping package.

• Unions are installed at the water coil.

• P/T test ports are located in the piping package to monitor pressure and temperature across the coil.

• Automatic fixed flow control increments are as follows: 0.5 to 4.0 GPM - 0.5 GPM; 5.0 to 9.0 GPM -1.0 GPM. Specify GPM when ordering.

• Maximum close-off pressure for 2-way control valves is 30 PSI, 3-way is 13 PSI. Contact factory whenhigher close-off pressures are required.

• A piping package diagram or detail must be submitted if accessories are required in locations otherthan indicated in the notes above. Additional engineering charges will apply and in some cases, alter-nate piping accessory locations may not be available due to dimensional or application constraints.See Valve Piping Package catalog (Stock ID CAT-FCU-PIPING). Contact factory for special pricing andauthorization number prior to quoting.

VH Notes

• A minimum of a manual piping package per coil is required on all VH units.

• Some restrictions may apply to the Y strainer with cleanout. Contact factory prior to quoting.

VF and HL Notes

• Piping packages are factory assembled and shipped loose for field installation to the fan coil unit.

• Piping packages are not available on DX or steam coils.

• Recommended water flow for 1/2" piping packages is 6.0 GPM with 25 PSIG close-off pressure maxi-mum; 3/4" is 12.5 GPM and 10 PSIG maximum. If water flow exceeds 12.5 GPM, contact factory forspecial pricing.

• 208/230/277 volt piping packages have extended lead times. Contact factory for ship cycle.

• Circuit setter is designed for full shut-off and replaces one ball stop isolation valve.

• Y strainer not available on Model HLE horizontal cabinet, or with auxiliary drip pans.

Manual Ball ValveA full port forged brass ball valve used to isolate the FanCoil Unit and/or associated piping. The valve requires man-ual operation.

Nominal Size: ½" ¾"Body Material: Brass BrassBall: Hard Chrome Hard Chrome

Plated PlatedSeats: Teflon TeflonStem Seal: (2) Viton O-Rings (2) Viton O-RingsConnection: Sweat SweatPressure Rating (psig): 600 600Temp. Rating, °F: 325 325Cv: 21 42

Manual Ball Valve With Memory StopAn adjustable stop position lever to limit travel of the On/Offhandle. This allows the ball valve to be closed, and returnedto the balance setting position without re-testing the system.

(See above ratings).

Typical 2-Way Control ValveA 2-position water control valve driven open or closed upona call for heating or cooling to maintain space tempera-ture. In open position, water can flow through the FanCoil Unit‘s water coil to heat or cool the space depend-ing on supply water temperature. In closed position, watercannot flow through the water coil. Control valves arepiped normally closed to the coil as standard. Valve actu-ators can be line or low (24VAC) voltage.

Nominal Size: ½" 2-Way ¾" 2-WayBody Material: Brass BrassConnection: Sweat SweatPressure Rating (psig): 300 300Temp. Rating, °F: 200 200Cv: 2.5 5.0Max. Close-off Press. (psig): 30 13Power Consumption: 7VA 7VA

NOTE: Photos are for representation purposes only. Vendors and models subject to change without notice.

GLOSSARY • FCU PIPING PACKAGES


Manual Circuit SetterA control fitting designed to allow maximum water flowthrough the Fan Coil Unit in the Open (0%) position, andas little as 10% of flow through the Fan Coil Unit in theClosed (90%) position. Has a calibrated nameplate, builtin test ports and adjustable mechanical stops, and is suit-able for positive shutoff.

Nominal Size: ½" & ¾"Body Material: BronzeConnection: SweatPressure Rating (psig): 300Temp. Rating, °F: 250Cv: Variable

Automatic Fixed Flow ControlA pressure compensated automatic fixed flow control devicedesigned to limit the GPM (gallons per minute) flow throughthe Fan Coil Unit. Automatic fixed flow control incrementsare: 0.5 to 4.0 GPM (in 0.5 GPM increments) and 5.0 to20.0 GPM (in 1.0 GPM increments), ±10%. Desired GPMmust be specified when ordering.

Nominal Size: ½" & ¾"Body Material: CopperConnection: SweatPressure Rating (psig): 500Temp. Rating, °F: 225Cv: Variable With

Inlet Pressure

Typical 3-Way Control ValveA 2-position water control valve driven open or closed (bypass)upon a call for heating or cooling to maintain space tempera-ture. Energized, water can flow through the Fan Coil Unit‘s watercoil to heat or cool the space depending on the supply watertemperature. The bypass port is blocked. De-energized, watercannot flow through the water coil but is forced to flow throughthe bypass port, bypassing the coil. Control valves are pipednormally closed to the coil as standard (in full bypass). Valveactuators can be line or low (24VAC) voltage.

Nominal Size: ½" 3-Way ¾" 3-WayBody Material: Brass BrassConnection: Sweat SweatPressure Rating (psig): 300 300Temp. Rating, °F: 200 200Cv: 3.0 5.0Max. Close-off Press. (psig): N/A N/APower Consumption: 7VA 7VA


UnionsA fitting used to provide a means of quickly disconnect-ing and re-connecting valve packages or field piping froma unit. The large nut on the union can be unscrewed andthe piping can be separated without cutting the pipe orunsoldering a joint. When ordered, unions are installedat the coil on the VF and HL Series Fan Coils. Unions arenot mounted on the VH Series Fan Coil.

Nominal Size: ½" & ¾"Body Material: Bronze/CopperConnection: SweatPressure Rating (psig): 125Temp. Rating, °F: 200

Y StrainerDesigned to allow water to flow through a built in screento filter debris or contaminates from the water system.With the water system isolated, the plug can be removedfrom the blowdown leg of the strainer and the captureddebris removed from the screen. After the plug isreplaced, the system can be put back in operation andthe strainer will continue to filter the unit‘s water.

Nominal Size: ½" & ¾"Body Material: BronzeConnection: SweatPressure Rating (psig): 200Temp. Rating, °F: 150Screen: 20 Mesh Stainless Steel

FCU PIPING PACKAGES • GLOSSARY


Balancing FittingA plug type valve designed to balance the waterside ofthe fan coil to ensure proper flow through the bypass cir-cuit of a 3-way control valve. Manual adjustment is required.No calibration is provided at the valve.

Nominal Size: ½" & ¾"Body Material: BronzeConnection: SweatPressure Rating (psig): 150Temp. Rating, °F: 200Cv: Adjustable


GLOSSARY • FCU PIPING PACKAGES


Optional Pressure/Temperature Test Port LocationsDesigned to allow testing of water pressure, differentialpressure or water temperature without interrupting thewaterside operation of the Fan Coil Unit. Sensor probes(1/8") are not included.

Nominal Size: ¼"Body Material: BrassConnection: ThreadedPressure Rating (psig): 400Temp. Rating, °F: 250

Aqua ThermostatAlso called an Automatic Seasonal Changeover Switch.The Aquastat is a line or low voltage changeover switchdesigned to switch a thermostat from heating to cooling based on a change in supply water temperature.Can be mounted on ½" or ¾" copper tube. Switchingaction is SPDT.Specifications: Switch on temperature rise, 85° (±6°)

Switch on temperature fall, 70° (±6°)Current Rating:- 5.8 FLA, 34.8 LRA (inductive); 10 amps (resistive) at 120VAC - 2.9 FLA, 17.4 LRA (inductive); 5 amps (resistive) at 240VAC- 3.6 FLA, 21.6 LRA (inductive); 1 amps (resistive) at 277VACAgency Approval: UL Listed, CSA Approved

Note: Specifications may vary.

Cleanout Valve for Y StrainerA standard ball valve with a cleanout valve installed onthe strainer blowdown leg to allow flushing the strainerscreen without removing the plug in the blowdown leg.This valve has a standard ½" garden hose connection toallow fluid to be piped to a container or remote locationduring cleaning.
