BEFORE YOU CALL FOR SERVICE, CHECK FOR
SEVERAL PROBLEMS THAT CAN BE EASILY SOLVED
If insufficient heating or cooling is suspected:
( ) Check for sufficient airflow. Check the air filter for dirt.
Check for blocked return- or supply-air grilles. Be sure they
are open and unobstructed. If these checks do not reveal the
cause, call your servicing dealer.
If your unit is not operating at all, check the following list for
easy solutions:
( ) Check to be sure that your thermostat temperature se-
lector is set above the indoor temperature during the heating
season, or below the indoor temperature during the cooling
season. Be sure the SYSTEM switch is in the proper HEAT,
COOL, or AUTO. position and not in the OFF position.
( ) Is the electrical supply switch ON? Are any fuses blown
or has the circuit breaker tripped?
( ) During the heating season, check the external manual
shutoff valve. Is this lever parallel with the pipe, indicating
that the valve is open? Or is the lever at a right angle, indi-
cating that the valve is closed? If closed, has the gas been shut
off for safety reasons? Otherwise, you may open the valve and
follow the start-up procedures listed in this manual.
NOTE: Before proceeding with the next check, shut OFF the
gas supply to the unit and then turn OFF the electrical
power supply to the unit. Remove the compressor access
panel.
( ) During the heating season, check the control switch on
the gas valve. Is it in the ON position? If it is not, be sure it
has not been turned off as a safety precaution. If no safety
hazards are present, follow the start-up procedures in this
manual.
( ) If your unit still fails to operate, call your servicing
dealer for troubleshooting and repairs. Specify the model
and serial numbers of your unit. (Record them in this man-
ual in the space provided.) If the dealer knows exactly which
unit you have, he may be able to offer suggestions over the
phone, or save valuable time through knowledgeable prepa-
ration for the service call.
IN CASE OF TROUBLE
If after performing the above routine checks, unit perfor-
mance is unsatisfactory, shut off the unit and call your
dealer.
