Cooling Chassis; Air Filter; Lubrication - Wolf Steel Condo Pack Installation And Operating Instructions Manual

6.2

COOLING CHASSIS

The cooling chassis contains all items related to the cooling functions of the unit, and also contains the indoor
blower and motor for the heating function. For extensive servicing, qualified personnel may choose to remove
the cooling chassis from the unit and take it to a work area. Spare chassis are recommended so that extensive
servicing can be performed outside the living space. This will prevent introducing dirt or doing damage in the
living area, and could help to eliminate significant disruption of the air conditioning and heating functions in the
living areas.
The indoor blower motor and the outdoor fan motor have permanently lubricated bearings and do not require
routine service. The refrigeration system is sealed and factory charged with Refrigerant R-410A so that routine
maintenance is not required. Cleaning of the outdoor coil, indoor coil, drain pan, and inside the bottom of the
chassis are recommended at least once a year, and more often if the equipment is operated in a dusty or
hostile environment. The electrical controls do not require routine service.
Power to the unit should always be turned OFF before performing service or removing the cooling or
furnace module from the unit. One power connector and one control circuit connector are provided for easy
disconnecting and re-connecting of the wires between the cooling chassis and cabinet. The front furnace panel
door must be removed to allow access to the wiring harnesses. After reinstalling the cooling chassis, both
panel doors must be reinstalled. Refer to "4.16.4.1 Air Conditioner Module Removal" section of this manual.

AIR FILTER

All indoor return air must be filtered. A permanent-type filter is pre-installed with the unit. It is located on the air

TO ITS PREVIOUS USE. REVERSING THE FILTER WILL CAUSE DUST TRAPPED WITHIN
THE FILTER TO BREAK FREE AND RECIRCULATE WITHIN THE DUCT SYSTEM. CONSULT
YOUR INSTALLATION CONTRACTOR OR SERVICE TECHNICIAN IF YOU HAVE ANY
QUESTIONS ON INSTRUCTIONS FOR REMOVING/REINSTALLING THE AIR FILTER.
