WARRANTIES
The 583B warranty is located at the back of this book. Be sure to
read the warranty carefully to determine the coverage for your unit.
BEFORE YOU CALL FOR SERVICE,
CHECK FOR SEVERAL EASILY-SOLVED PROBLEMS
If insufficient heating or cooling is suspected:
( ) Check for sufficient airflow. Check the air filter for dirt. Check
for blocked return-air 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 is in the proper HEAT or COOL 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, 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 gas
supply, then the electrical power supply to the unit. Remove the
control access door.
( ) During the heating season, check the control dial on the internal
gas valve. Is it in the ON position? If it is not, be sure it was not
turned off for the propose of safety. If no safety hazards exist,
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 and unit performance is still
unsatisfactory, shut off the unit and call your dealer.
