Aqua Phase AQ-F250, Operating Manual, Page: 46 / 89

V alve inspection can be performed while the valve is still piped in line.
The Valves to be inspected may be:
•
Fill Line Valve
•
Disinfectant Line Valve
(Option)
•
Drain Valve (pre - 2005)
•
Main Chamber Valve (Pre - 2005).
1. Unplug the Aqua Phase from the power Supply
2. Turn off the water supply to the Aqua Phase
3. Loosen the Fill Line connection (to release water pressure).
4. Remove the Retainer clip or Cap
5. Remove the Data Label Plate if an Asco Valve.
6. Lift the Unit Solenoid (electrical coil) up, off the Plunger Tube Assembly (
Do not mis
-
place
the spring or tension clip on the Plunger Tube assembly).
7. Remove the bolts connecting the valve Cover/Solenoid Base to the valve Body.
8. Separate the valve Cover/Solenoid Base AND the Diaphragm from the valve Body. (
Be
sure
not to mis
-
place the springs between the Cover/Solenoid Base and the Diaphragm). Pay
attention to the location of the valve Body Gasket/O-ring.
9. Look at/into the valve Body for and dirt or debris, and remove if any exists.
10. Carefully, separate the Diaphragm for the Cover/Solenoid Base.
11. Inspect the Diaphragm for any damage or wear such as cracking, blisters, or warps. The
Diaphragm should have the same pliability/flexibility across its surface.
12. Locate the Bleed Hole (1/2” Valves) in the Diaphragm and make certain it is not plugged or
clogged with debris or hard water particles.
13. Check that the Core Spring and Core Assembly moves freely inside the Cover/Solenoid base.
If you find there are issues with items 11, 12, or 13 from above, a valve rebuild kit may need to
be ordered and installed.
When reassembling the valve:
IT IS CRITICAL TO VALVE OPERATIONS THAT THE BLEED HOLE be towards the
“OUT” stamped into the va lv e Body
(the Bleed Hole will be at about 45 degree from the “OUT”
stamp).
IT IS CRITICAL TO VALVE OPERATIONS THAT BOTH THE Core Spring and Diaphragm
Spring exist and are in position.
