Bryant 583A - Manual (Page 7)

VIII. Electrical Controls and Wiring
Electrical controls are difficult to check without proper in-
strumentation; therefore, if there are any discrepancies in the
operating cycle, contact your dealer and request service.
IX. Refrigerant Circuit
The refrigerant circuit is difficult to check for leaks without
the proper equipment; therefore, if inadequate cooling is sus-
pected, contact your local dealer for service.
X. Combustion Area and Vent System
The combustion area and vent system should be inspected
visually before each heating season. The normal accumula-
tion of dirt, soot, rust, and scale can result in loss of effi-
ciency and improper performance if allowed to build up.
CAUTION: If your unit makes an especially loud noise
when the main burners are ignited, shut down the heat-
ing section and call your dealer.
Proceed as follows to inspect the combustion area and power-
venting system of your unit.
1. Turn off electrical power and gas supply to your unit.
2. Remove burner access panel. (See Fig. 1.)
3. Using a flashlight, carefully inspect the burner areas for
dirt, soot, rust, or scale. See Fig. 2.
CAUTION: If dirt, soot, rust, or scale accumulations
are found, call your dealer and do not operate your heat-
ing section.
4. When you have completed your inspection, follow the
start-up procedures in this manual to restore your unit
to operation.
5. Observe unit heating operation.
WARNING: Components in heat section may be hot
after unit has been started up. When observing flame,
be careful not to get close to or touch heating compo-
nents or serious personal injury may result.
Watch the burner flame to see if it is bright blue. If you
observe a suspected malfunction or if the burner flames
are not bright blue, call your dealer.
6. Replace burner access panel.
XI. Unit Panels
After performing any maintenance or service on the unit, be
sure all panels are fastened securely in place to prevent rain
from entering unit cabinet and to prevent disruption of the
correct unit airflow pattern.
REGULAR DEALER MAINTENANCE
In addition to the type of routine maintenance you might be
willing to perform, your unit should be inspected regularly
by a properly trained service technician. An inspection (pref-
erably each year, but at least every other year) should in-
clude the following:
1. Inspection of all flue product passages — including the
burners, heat exchanger, and flue collector box.
2. Inspection of all combustion- and ventilation-air pas-
sages and openings.
3. Close inspection of all gas pipes leading to and inside
of your unit.
4. Inspection and, if required, cleaning of the condenser
and evaporator coils.
5. Inspection and, if required, cleaning of the evaporator
drain pan.
6. Inspection and cleaning of blower wheel housing and
motor.
7. Inspection of all supply-air and return-air ducts for leaks,
obstructions, and insulation integrity. Any problems
found should be resolved at this time.
8. Inspection of the unit base to ensure that no cracks,
gaps, etc., exist which may cause a hazardous
condition.
9. Inspection of the unit casing for signs of deterioration.
10. Inspection of all electrical wiring and components to
assure proper connection.
11. Inspection for leaks in the refrigerant circuit. Pressure-
check to determine appropriate refrigerant charge.
12. Inspection of compressor oil level.
13. Operational check of the unit to determine working con-
ditions. Repair or adjustment should be made at this
time.
Your servicing dealer may offer an economical service con-
tract that covers seasonal inspections. Ask for further
details.
Complete service instructions can be found in the unit
Installation, Start-Up and Service Instructions.
