CHECK PROCEDURE
Check Screen on Pilot Strainer
1. Using the GBE, manually cycle the
pilot as required until the piston(s) in
question should be closed. (Refer to
Table 13 on page 72). Remove the
tubing from the inlet to the pilot valve
strainer and check for water from the
tube.
2. Manually cycle the pilot to position #1.
1. Remove the external plumbing con-
nections and clamp. Remove valve
body from tank adapter. Lay the valve
body on its side. Attach an external air
supply, hand vacuum/pressure pump
with gauge or water supply to the spool
body pressure port.
2. While in position #1 and not in stand
by (multiple units with blocking sole-
noids). Confirm the correct piston func-
tion using Table 13 on page
3. Using the GBE, manually cycle the pi-
lot to position #2. Confirm the correct
piston function using Table
4. Using the GBE, manually cycle the
pilot to position #3. Confirm the correct
piston function using Table
5. Using the GBE, manually cycle the
pilot to position #4. Confirm the correct
piston function using Table
6. Using the GBE, manually cycle the
pilot to position #5. Confirm the correct
piston function using Table
7. Using the GBE, manually cycle the pi-
lot to position #1.
Remove the valve manifold and check refill
piston spring.
Incorrectly sized drain line flow control
Incorrect programming
Verify operation of the motorized ball valves
of the control valve.
Clogged Screen prevents control
pressure from reaching pilot valve
(and solenoid valves if applicable).
If water flows out of the tubing, check
the fitting in the valve inlet port and pi-
lot valve strainer for an obstruction. If
water does not flow out of the control
tubing, check the tubing and fittings
for an obstruction.

Correct programming. See the GBE
Programming for Commercial Soften-
ers and Filters, except for HF xN Man-
ual (P/N 01027295)
Motorized ball valve may not be prop-
erly wired or water hardness scale
build-up inside motorized ball valve is
causing malfunction. (See
