UNIT OPERATION HAZARD
Failure to follow this caution may result in property
damage,
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 and blower motor and/or
compressor damage,
A dirty air filter will cause excessive strain on the compressor and
blower motor. This can cause the components to overheat and
automatically shut down. In the extreme, the components will fail
and need to be replaced. To avoid inefficient or failed 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 cold
water and mild detergent, then rinsed and thoroughly dried. THE
FILTER MUST BE COMPLETELY DRY BEFORE BEING
REINSTALLED. To avoid prolonged shutdown of your unit while
a filter is drying, you should have an extra filter on hand. This
would allow you to rotate between the two with minimal downtime
for your comfort system. Extra filters may be purchased from your
dealer.
The filter(s) and filter rack for a packaged system are supplied and
installed by the contractor or dealer. Typically, the filter(s) and rack
are located in the return-air duct at the outdoor 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 from
the unit, minimal care should be sufficient 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 for service.
Unit Support
Your packaged unit should be maintained 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 promptly to assure
condensate drainage out of the unit. If you notice that water or ice
collects beneath the unit, arrange for it to be drained away from the
unit.
BEFORE YOU CALL FOR SERVICE
CHECK FOR THESE EASILY SOLVED
PROBLEMS
Check the indoor and outdoor disconnect switches. Verify that
circuit breakers are ON or that fuses have not blown.
Check for sufficient airflow. Check the air filter(s) for any
accumulations of dirt. Check for blocked return-air or supply air
grilles. Be sure grilles are open and unobstructed.
Check the settings on your indoor thermostat. If you desire
cooling, see that the temperature control selector is set below room
temperature and the SYSTEM switch is on the COOL or AUTO
position. If you require warmth, be sure the temperature control
selector is set above room temperature 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.
