CHECK THE AIR FILTER
A dirty air filter wilt cause excessive strain on the compres-
sor and blower motor. This can cause the components to over-
heat and automatically shut do,am. In the extreme, the com-
ponents will tail and need to be replaced. To avoid inefficient
or tailed operation of your unit, CHECK THE FILTER(S)
EVERY 3 TO 4 WEEKS. Replace filter(s) when necessary,
or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters
of the same dimensions.
Reusable, permanent filters should be washed in a solution
of cotd water and mild detergent, then rinsed and thoroughly
dried. THE FILTER MUST BE COMPLETELY DRY BE-
FORE BEING REINSTALLED. To avoid prolonged shut-
do,am of your unit while a filter is drying, you should have
an extra filter on hand. This would allow you to rotate be-
tween the two with minimal downtime tbr your comfort sys-
tem. Extra filters may be purchased fioln your dealer.
The filter(s) and filter rack for a packaged system are sup-
plied and installed by the contractor or dealer. Typically, the
filter(s) and rack are located in the return-air duct at the out-
door unit or behind the return-air grille(s). Have your dealer
show you the location of your filter(s) and the procedures
for removal and replacement.
If you have any questions about the removal and/or cleaning
of your filter(s), contact your dealer for assistance.
If grass clippings, leaves, shrubbery, and debris are kept away
fiom the unit, minimal care should be sulticient to keep the
system functioning properly. However, if the outdoor coil
becomes dirty, use a brush or vacuum cleaner and soft brush
attachment to clean the exterior surface. If dirt is trapped
deep in the coil, contact your dealer t\_r service.
UNIT SUPPORT
Your packaged unit should be lnaintained at a level position.
If its support should shift or settle so that the unit is no longer
level, you should correct the condition. Relevel it prolnptty
to assure condensate drainage out of the unit. If you notice
that water or ice collects beneath the unit, arrange _\_rit to
be drained away from the unit.
BEFORE YOU REQUEST A SERVICE CALL
BEFORE YOU CALL FOR SERVICE, CHECK FOR
THESE EASILY SOLVED PROBLEMS:
Check the indoor and outdoor disconnect switches. Veril_
that circuit breakers are ON or that fuses have not blown.
Check for sui_cient airflo,a: Check the air filter(s) for any
accumulations of dirt. Check tbr blocked return-air or supply-
air grilles. Be sure grilles are open and unobstructed.
Check the settings on your indoor therlnostat. If you desire
cooling, see that the telnperature control selector is set be-
low room temperature and the SYSTEM switch is on the
COOL or AUTO position. If you require warlnth, be sure the
telnperature control selector is set above room telnperature
and the SYSTEM switch is at HEAT or AUTO. The FAN
switch should be set at ON for continuous blower operation
or AUTO if you wish the blower to function only while the
unit is operating.
If your comfort system still Ihils to operate, contact your ser-
vicing dealer for troubleshooting and repairs. Specil_ your
apparent problem, and state the model and serial nmnbers
of your equipment. (You should have them recorded on this
page.) With this information, your dealer may be able to of-
fer helpful suggestions over the phone, or save valuable time
through knowledgeable preparation for the service call.
