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 the ball valve. Then disconnect tubing from
solenoid 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 back-
washes occur at the wrong time.
2. Plumbing bypass valve(s) must be in SERVICE
position (see Figure 7, page 8).
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, and the power cable fastened securely?
5. The valve drain hose must be free of kinks and
sharp bends.
6. If the air pump is not running, check for binding of
the turbine, check that the leads of the relay box are
connected to the back of the faceplate and there is
power to the relay box.
If you do not find the problem after making the initial
checks, do the MANUAL ADVANCE DIAGNOS-
TICS.
