5.3.2 Capacitor Replacement
The capacitor starts the compressor. If the compressor cannot start, the
capacitor may be defective and require replacement. To replace the
capacitor, take the following steps:
1 Set the unit’s ON/OFF switch to the OFF position, and unplug
the power cord.
2 Remove the side and lower front panels.
3 Disconnect the two leads to the capacitor and slide capacitor
out of the tie wrap holding it in place.
4 To install the new capacitor, connect the leads and slide the
capacitor into the tie wrap holding it in place.
5.4 Solenoid Valves
The NewLife uses 5 two-way solenoid valves: two feed, two waste, and one
equalization. Each valve has an open (energized) and closed (de-energized)
position. As the NewLife operates, two valves are always energized.
The solenoid valves of the NewLife unit require no scheduled maintenance.
If a valve becomes noisy, you can easily replace the internal valve parts. To
identify the noisy valve, observe which green circuit board light illuminates
at the time of the noise. The lighting matrix on the circuit board corresponds
to the valve location.
5.4.1 Feed or Waste Valve Rebuilding
The two feed valves and two waste valves are located on the unified
valve block. This valve block does not require removal to rebuild a
feed or waste valve.
1 Set the ON/OFF switch to the OFF position, and unplug the
power cord.
2 Remove the side and back panels.
3 Remove the retaining cap from the appropriate valve with a
slotted-head screwdriver.
4 Lift off the solenoid coil.
