3. For “Roof Top Application,” unit must be elevated above roof with a mounting Curb or Frame. 4. Exhaust vents or other sources of contaminated air should not be near unit air inlet if outside air is to be introduced as a make-up air or the economizer ventilation feature is to be used. - Page 8 OUTDOOR COIL END OF UNIT “B” DRIP LIP BAYLIFT002A LIFTING LUGS DIMPLE GASKET SEAL NOTE: The inner perimeter of the Drip Lip on all units should be flush with the outer perimeter of the curb on the two sides shown here. See Figure 2 for the location of the unit overhang on the WCY036-060G Models with BAYCURB030A.
- Page 9 ROOFTOP -- UNITS For roof top applications using a field fabricated frame and ducts, use the following procedure: 1. The frame must be located and secured by bolting or welding to the roof. Flashing is required. 2. The hole in the roof must be prepared in advance of installing the unit.
- Page 10 GROUND LEVEL -- HORIZONTAL UNITS For ground level installations, the unit should be positioned on a pad the size of the unit or larger. The unit must be level on the pad. The pad must not come in contact with the structure (See Figure 11.) Be sure the outdoor portion of the supply and return air ducts are as short as possible.

Page 12: Filter Installation
AIR FILTERS Filters are to be used with the WCY024-060G heating/cooling units. The basic unit does not have filters in it. However, a filter frame accessory is offered that will allow filters to be installed within the unit. Otherwise a filter rack must be installed by the installer in the duct work. - Page 13 After all electrical wiring is complete, set the thermostat system switch in the OFF position so that the compressor will not run and then apply power by closing the system main disconnect switch. This will activate the compressor sump heat. Do not change the Thermostat System Switch until power has been applied long enough to evaporate any liquid R-22 in the compressor.

See Figure 5. ● Is the duct work correctly sized, run, taped, insulated, and weatherproofed with proper unit arrangement. See Ductwork Installation section. ● Is the condensate line properly sized, run, trapped, and pitched? ●...

Page 15: Sequence Of Operation
GENERAL Operation of the unit heating and cooling cycles is automatic for HEAT and COOL functions. (The optional automatic changeover thermostat, when in the AUTO position, automatically changes to heat or cool with sufficient room temperature change.) The fan switch can be placed in either the ON position, causing continuous evaporator (indoor) fan operation, or the AUTO position causing fan operation to coincide with heating or cooling run cycles. -
Page 16: Demand Defrost System
DEMAND DEFROST SYSTEM DEFROST CONTROL The demand defrost control measures heat pump outdoor ambient temperature with a sensor located outside the outdoor coil. A second sensor located on the outdoor coil is used to measure the coil temperature. The difference between the ambient and the colder coil temperature is the difference or delta-T measurement. -
