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, follow the
steps below:
1. Set the unit’s I/ 0 switch to the “0” position and disconnect 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 Intensity uses five 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 Intensity operates, two valves are always energized.
The solenoid valves of the NewLife Intensity 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/Waste Valve Replacement
Feed/Waste Valve Removal
To remove the feed or waste valves, follow the steps below:
1. Set the unit’s I/ 0 switch to the “0” position and disconnect the power cord.
2. Remove the side and back panels.
3. Remove the red cap from the appropriate valve with a slotted-head
screwdriver.
4. Lift off the solenoid coil.
Correct direction of spring is required for proper valve function.
5. Loosen and remove the valve using a one-inch deep well socket. Be sure to
also remove and discard valve o-ring.
Feed/Waste Valve Installation
To install a feed or waste valve, follow the feed/waste valve removal procedure in
reverse order. Make sure to install new o-ring and test for leaks.
5.4.2 Solenoid Valve Coil Replacement
An ohmmeter can be a useful tool in determining the condition of a valve coil.
When using and ohmmeter in the NewLife Intensity unit, valve coil readings
should be as indicated below:
1. 120VAC units
a. EQ coil = 800ohms +/- 10%
b. Feed/waste coil = 800ohms +/- 10%
