BEFORE YOU CALL FOR SERVICE, CHECK
FOR 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 selector
is set above the indoor temperature during the heating season,
or below the indoor temperature during the cooling season. Be
sure the SYSTEM switch 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 shut-
off valve. Is this lever parallel with the pipe, indicating that the
valve is open? Or is the lever at a right angle, indicating 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, turn OFF the
electrical power supply to the unit. Remove the control access
door.
( ) During the heating season, check the control dial on the
gas valve. Is it in the ON position? If it is not, be sure it has not
been turned off for safety reasons. 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 manual 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 preparation for the
service call.
IN CASE OF TROUBLE
If, after performing the above, unit performance is unsatis-
factory, shut off the unit and call your dealer.
