WARNING: FILTER
TANK CONTAINS AIR.
TO RELIEVE PRES-
SURE, PUT BYPASS
VALVE IN BYPASS AND
ADVANCE FILTER VALVE
TO BACKWASH BEFORE
DISASSEMBLY.
Adaptor Troubleshooting Guide
If excess air is in household plumbing, the air vent is
most likely plugged with debris.
Close ball valve. Then disconnect tubing from sole-
noid inlet, as shown below. Remove the inlet screen,
located inside the inlet port of the solenoid. Clean
and reinstall the inlet screen.
After vent is cleared, reconnect tubing, open ball
valve and check for leaks.

Description of Operation
-- Air pump activation & solenoid venting system
When service water flows through the filter, it rotates the turbine (located in the valve’s outlet port), sending a
signal to the controller (PWA). The controller then activates a 24V power supply to the vent solenoid and relay
box. When activated, the relay box turns on the 120V power supply to the air pump. The air pump adds a head of
air in the filter tank. This supplies oxygen that aerates the water and oxidizes iron, manganese and hydrogen
sulfide (generating particles). The vent solenoid is opened during this time, permitting oxygen--depleted air to
escape and be continuously replaced in the tank by fresh air. After oxidation, the birm filtration media filters out
the particles. During the backwash / rinse cycles, the filter cleans itself. During regenerations the air pump and
vent solenoid do not activate. After service water flow stops, the air pump will run for an additional 8 seconds.
TROUBLESHOOTING
ALWAYS MAKE THESE
INITIAL CHECKS
FIRST
1.
Does the time display show the correct time of day?
...If display is blank, check power source to the filter.
...If time is flashing, power was off for over 6 hours. The filter resumes normal operation but backwashes occur
at the wrong time.
2.
Plumbing bypass valve(s) must be in SERVICE position, Figure 6, page 9.
3.
The inlet and outlet pipes must connect to the filter inlet and outlet respectively.
4.
Is the transformer plugged into a “live” grounded wall outlet?
5.
The valve drain hose must be free of kinks and sharp bends.
If you do not find the problem after making the initial checks, do the MANUAL ADVANCE DIAGNOSTICS.
