Routine Maintenance - Bryant 583B Series User's Information Manual

ROUTINE MAINTENANCE

All routine maintenance should be handled by skilled, experienced
personnel. Your dealer can help you establish a standard proce-
dure.
For your safety, keep the unit area clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.
To assure proper functioning of the unit, flow of combustion and
ventilating air must not be obstructed from reaching the unit.
Clearance of at least 48 in. is required from top of unit and on sides
except the power entry side (42 in. clearance) and the duct side (12
in. minimum clearance).
MAINTENANCE AND CARE FOR THE EQUIPMENT
OWNER
Before proceeding with those things you might want to maintain
yourself, please carefully consider the following:
WARNING:
1. TURN OFF GAS SUPPLY AND ELECTRICAL
POWER TO YOUR UNIT BEFORE SERVICING OR
PERFORMING MAINTENANCE.
2. Do not turn off electrical power to this unit without
first turning off the gas supply.
3. When removing access panels or performing mainte-
nance functions inside your unit, be aware of sharp
sheet metal parts and screws. Although special care is
taken to reduce sharp edges to a minimum, be ex-
tremely careful when handling parts or reaching into
the unit.
Failure to follow these instructions may result in serious
injury or death.
A. Air Filters
Air filter(s) should be checked at least every 3 or 4 weeks and
changed or cleaned whenever it becomes dirty. Dirty filters
produce excessive stress on the blower motor and can cause the
motor to overheat and shut down. Table 1 indicates the correct
filter size for your unit. Refer to Fig. 3 to access the filter(s).
To replace or inspect filter(s) (or accessory filter rack when
supplied):
1. Remove the filter access panel using a 5/16-in. nut driver.
2. Remove the filter(s) by pulling the filter(s) out of the unit.
If the filter(s) is dirty, clean or replace with new one.
When installing the new filter(s), note the direction of the airflow
arrows on the filter frame.
If you have difficulty in locating your air filter(s), or if you have
questions concerning proper filter maintenance, contact your
dealer for instructions. When replacing filters, always use the same
size and type of filter that was supplied originally by the installer.

CAUTION: Never operate your unit without filters in
place. Failure to heed this warning may result in damage
to the blower motor and/or compressor. An accumulation
of dust and lint on internal parts of your unit can cause
loss of efficiency and, in some cases, fire.
B. Heat Exchanger
To ensure dependable and efficient heating operation, the heat
exchanger should be checked by a qualified maintenance person
before each heating season, and cleaned when necessary. This
checkout should not be attempted by anyone not having the
required expertise and equipment to properly do the job. Checking
and/or cleaning the heat exchanger involves removing the gas
controls assembly and the flue collector box cover and, when
completed, reinstalling the gas controls assembly for proper
operation. Also, the flue collector box cover must be replaced
correctly so that a proper seal is maintained. Contact your dealer
for the required periodic maintenance.
C. Fans and Fan Motor
Periodically check the condition of fan wheels and housings and
fan-motor shaft bearings. No lubrication of condenser- or
evaporator-fan bearings or motors is required or recommended.
D. Evaporator and Condenser Coils
Cleaning of the coils should only be done by qualified service
personnel. Contact your dealer for the required annual mainte-
nance.
E. Condensate Drain
The drain pan and condensate drain line should be checked and
cleaned at the same time the cooling coils are checked by your
dealer.
F. Compressor
All compressors are factory-shipped with a normal charge of the
correct type refrigeration grade oil in them and should rarely
require additional oil.
