DISTRICT COOLINGDistrict cooling provides chilled water from a cooling plant through a network of pipes to multipleresidential, industrial and commercial buildings for air conditioning purpose.

A typical district cooling system requires the FCUs to operate with a 80C - 90C delta temperature.

Entering water temperature to the Fan Coil Unit is expected to be between 5.50C and 6.50C.

District Cooling Benefits:

District cooling systems provide a variety of benefits, both qualitative and economic. The qualitativeadvantages are perceived in terms of better comfort, better reliability and maximized convenience.Mechanical cooling and air conditioning requirements are growing rapidly throughout the world,partly because there are many new buildings being built and partly because those buildings arebeing built in warm climates. However, no matter where those buildings are built, they tend to betighter and more densely packed than they used to be. This creates a need for air conditioning even

in cold climates.

People are also increasingly emitting more and more heat into buildings through all types of electronicequipment that generate extra heat such as computers and various other gadgets. All this has led toa growing demand for comfort in homes and offices, a need that is directly addressed by DistrictCooling.

The economic benefits can be experienced by both the owner and the tenant, where the capitalcosts of control panels, internal power distribution, annual maintenance and power consumptioninside the building are reduced and the cost of chillers are eliminated.

* Better quality of cooling

* Maximum cost effectiveness

* Capital cost elimination

* Space saving

* Decrease in sound pollution

* Environmental friendly

INSTALLATIONThe complete shipment should be inspected for damage. Any damage, visible or concealed, should be reported immedi-ately to the delivery man or driver and noted on the shipping invoice.

Place unit in position and make sure that unit is level. This is important to assure proper drainage and operation. Slots

provided in the mounting brackets should be used for installing the units.

ELECTRICALPlease ensure power supply (V-Ph-Hz) to the unit is as per unit nameplate requirements.

Caution: Operation of the unit on improper power supply will result in damage to the unit.

Warning: Before installation or servicing, always TURN OFF all power to the unit. There may be more than one discon-

nect switch. Ensure all of them are turned off.

GROUND & POWER WIRESConnect power wires as per wiring diagram. Connect ground wire to the ground lug inside the control box.

MAINTENANCECOILCoil may be cleaned by removing and brushing between fins with a stiff wire brush. Brushing should be followed by cleaning

with vacuum cleaner. The coil may also be cleaned by using a high pressure air, if compressed air source is available. It

should be pointed out that if air filters are used and periodically cleaned, the coils will not be clogged up prematurely.

DRAIN PIPEDrain pipe should be checked before summer operation of unit. If it is clogged, steps should be taken to clear the debrisso that condensate will flow out easily. A standard pipe cleaner for 1/2" ID pipe may be used. Periodic checks of the drain

pipe should be taken during summer operation, as there is a possibility of it becoming clogged with dirt.

FILTER CLEANINGRemove access panel, slide filter out of filter rack, and clean as follows:Tap filter on solid surface to dislodge heavy particles. Wash under stream of hot water. If filter has been put to exceptional

service, a mild solution of Sal-Soda, Tri-Sodium Phosphate or any other commercial solvent can be used. Set filter onend with slots in frame down, which allows it to drain. Filters should dry thoroughly before reuse.

REPLACEMENT PARTSWhen writing for replacement parts, refer to model number and serial number on the nameplate of the unit.
