Planned Maintenance
Preventive maintenance is the best way to avoid unnecessary
expense and inconvenience. Have this system inspected at
regular intervals by a qualified service technician. The required
frequency of inspections depends upon the total operating time
and the indoor and outdoor environmental conditions. Routine
maintenance should cover the following items:
• Tighten all belts, wire connections, and setscrews.
• Clean the evaporator and condenser coils mechanically
or with cold water, if necessary. Usually any fouling is
only matted on the entering air face of the coil and can be
removed by brushing.
•
Check each circuit’s refrigerant sightglass when
the circuit is operating under steady-state, full load
conditions. The sightglass should then be full and clear. If
it is not, check for refrigerant leaks.
NOTE:
A partially full sight glass is not uncommon at part
load conditions.
• Check for proper superheat.
• Check for proper subcooling.
• Check for blockage of the condensate drain. Clean the
condensate pan as needed.
• Check the power and control voltages.
• Check the running amperage of all motors.
• Check all operating temperatures and pressures.
• Check and adjust all temperature and pressure controls
as needed.
• Check and adjust all damper linkages as needed.
• Check the operation of all safety controls.
• Check the condenser fans and tighten their setscrews.
• Lubricate the door latch mechanisms.
