5.4 Solenoid Valves
The NewLife 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 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.
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 ON/OFF switch to the OFF 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.
