VI. MAINTENANCE
Refrigerant Charging
Unit is factory charged. When recharging is necessary, blow
any refrigerant remaining in system, then weigh in total
charge indicated on unit rating plate. Standard 1/4-inch
Schrader service connections are provided on high and
low sides of refrigerant system for evacuation and charging.
Cleaning
Before cleaning, disconnect electrical power.
Condenser Coil: Lift or remove unit top cover for access to
condenser coil. Inspect coil periodically. Clean with brush,
vacuum cleaner, low-pressure water, steam, or air.
Evaporator Coil: Lift or remove unit top cover for access
to evaporator coil. Inspect coil periodically. Clean with
brush, vacuum cleaner, or low-pressure air.
NOTE: When cleaning condenser coil or evaporator coil, be
sure to thoroughly clean out the spaces between fins.
Return Air Filter: Clean filter a minimum of twice yearly.
Flush permanent type with hot water, steam; or soak in
mild solution of soap, or detergent, and water. Allow filters
to dry, and replace. Refer to filter manufacturer’s in­
structions, as required, for other types of filters.
This Bryant self-contained cooling unit is designed and in­
stalled to provide maximum comfort. Adherence to
following guidelines will help promote greater efficiency
and longer operating life.
1. Do not rapid-cycle unit. Allow at least 3 minutes
before returning unit to operation after shutdown.
On size 048 units, do not manually override
COMPROTEC^.
2. If there is a general power failure, it is recommended
that electrical power supply be turned off at unit
disconnect switch until electrical power supply to
building is restored. This prevents excessive current
draw that would result from momentary low-voltage
conditions at time power is restored.
3. Air filters should be cleaned or replaced regularly to
protect against restricted airflow across cooling coil.
4. Size 048 units incorporate Bryant’s COMPROTEC™
system for compressor protection. If compressor
overloads or hi-pressure switch have cause to function,
COMPROTEC ™ system will hold unit off for approxL
mately 5 minutes. At that time, unit will try to restart.
Should original condition still exist, unit will again
cycle on COMPROTEC™ system.
