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.
