Daikin Rebel Applied Heating and Cooling (IM 1287): Planned Maintenance

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 sight glass when the circuit is operating under steady-state, full load conditions. The sightglass should then be full and clear. It 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.
