grille assembly by reversing items
1 through 4.
INDOOR-AIR COIL
Eventually, minor amounts of lint and
dirt may pass through the filter and
collect on the indoor-air coil. These
minor accumulations can be carefully
vacuumed away with a brush
attachment on a vacuum cleaner.
Care must be taken to prevent
bending the soft fins on the coil.
If the fins are accidentally bent, most
air conditioning service technicians
have a tool for straightening bent fins.
UNIT EXHAUST AND
OUTDOOR-AIR INTAKE
The unit’s exhaust and outdoor-air
intake must remain clear. Check
the unit exhaust frequently. Keep it
free of all debris, snow, or ice. The
outdoor-air intake should also be kept
free of obstructions. Blocking the
exhaust or outdoor-air intake opening
will reduce the efficiency of your unit,
could damage it, and void your
warranty.
CONDENSATE DRAIN
The condensate drain must be routed
to a suitable drainage area. Check
the unit condensate drain periodically.
Keep it free of anything that may
block or impede the flow of condensate
water. If there is any accumulation
of foreign matter in the drain pipe,
it should be removed and
cleaned.
BEFORE YOU REQUEST
A “SERVICE CALL’’
• Check disconnect switches. Verify
that circuit breakers are ON or that
fuses have not blown.
• Check for sufficient airflow. Check
the air filter for any accumulations
of dirt. Check for blocked
return-air or supply-air registers. Be
sure registers 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 or MODE control
is set to COOL or AUTO. If you
require heat, be sure the temperature
control selector is set above
room temperature and the
SYSTEM or MODE control is set
to HEAT or AUTO. The FAN
control should be set to ON for
continuous blower operation or
AUTO if you wish blower to
function only while the unit is
operating.
