MAINTENANCE AND SERVICE
This section discusses maintenance that should be performed on
your system. Most maintenance should be performed by your dealer. You, as the owner, may wish to handle some minor maintenance
for your new unit.
With the SYSTEM or MODE control set to COOL, your unit will
run in cooling mode until the indoor temperature is lowered to the
level you have selected. On extremely hot days, your unit will run
for longer periods at a time and have shorter “off” periods than on
moderate days.
Routine Maintenance
Gas Heating Mode
All routine maintenance should be handled by skilled, experienced
personnel. Your dealer can help you establish a standard procedure.
With the SYSTEM or MODE control set to HEAT, your unit will
run in heating mode until the room temperature is raised to the level
you have selected. Of course, your unit will run for longer periods
to maintain a comfortable environment on cooler days and nights
than on moderate ones.
To assure proper functioning of the unit, flow of condenser air must
not be obstructed from reaching the unit. Clearance from the top of
the unit is 48 in. (1219 mm) Clearance of at least 36 in. (914 mm)
is required on sides except the power entry side (42 in. [1067 mm]
clearance) and the duct side (12 in. [305 mm] minimum clearance).

WARNING
FIRE AND UNIT OPERATION HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
2. When removing access panels or performing maintenance
functions inside your unit, be aware of sharp sheet metal
parts and screws. Although special care is taken to reduce
sharp edges to a minimum, be extremely careful when
handling parts or reaching into the unit.
Never operate your unit without filters in place. An
accumulation of dust and lint on internal parts of your unit can
cause loss of efficiency.
Fans and Fan Motors
Air Filters
Periodically check the condition of fan wheels and housings and
fan--motor shaft bearings. Contact your dealer for the required
annual maintenance.
The air filter(s) should be checked every 3 or 4 weeks and changed
or cleaned whenever it becomes dirty. Dirty filters produce excessive stress on the blower motor and can cause the motor to overheat
and shut down.
Indoor and Outdoor Coils
Cleaning of the coils should only be done by qualified service personnel. Contact your dealer for the required annual maintenance.
This unit must have air filters in place before it can be operated.
These filters can be located in one of at least two places. In many applications, the installer will provide return air filter grilles mounted
on the wall or ceiling of the conditioned structure. In the instance of
filter grilles, the filters can simply be removed from the grille and replaced.
Condensate Drain
The drain pan and condensate drain line should be checked and
cleaned at the same time the cooling coils are checked by your dealer.
The other typical application is an accessory filter rack installed inside the unit itself. The following information is given to assist in
changing filters used in these internal filter racks.
Compressor
All compressors are factory shipped with a normal charge of the correct type of refrigeration grade oil. A compressor should rarely require additional oil.
Table 1 indicates the correct filter size for your unit. Refer to Fig. 2
to access filters installed in the accessory filter rack.
