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 BACview display to be sure unit has not been dis-
abled. Check set points are properly set.
( ) 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 the 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 gas section
access panels.
( ) During the heating season, check the switch on the gas
valve. Is it in the ON position? If it is not, be sure it has not
been turned off for the purpose of safety. 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 checks, unit performance is
unsatisfactory, shut off the unit and call your dealer.
