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 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 chassis 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 controls enclosure cover
must be removed to allow access to the screws holding the
indoor blower cover plate to the cooling chassis and cabinet.
After reinstalling the cooling chassis, the indoor blower cover
plate and controls enclosure cover must be reinstalled.
IF YOU TURN OFF POWER SUPPLY, TURN
OFF THE GAS. SEE HAZARD LEVELS,
