Manual Operation:
A
Manual on: Turn the solenoid counter-clockwise
1/4 turn. Do not unscrew completely. To close,
hand tighten clockwise.
B
Flow control (select models only): Turn clock-
wise to restrict flow. Turn counter-clockwise to
open flow.
C
Flush valve to clear debris: Turn the bleed screw
counter-clockwise ONLY 1 turn. Flush one min-
ute and turn clockwise to close.
First Use:
D
Open the main water supply and flush one min-
ute with bleed screw to clear debris.
E
Test wiring by using the Manual Water feature

NOTE:
For flows below 3 GPM (0.75 m3/h), or
any drip application, use a 200 mesh filter up-
stream and a pressure regulating filter down-
stream from the valve. 40 psi for 1” and 30 psi for
3/4” drip lines.

Turn On at
the Timer
Verify timer settings are correct
Check and repair wiring and connections as
needed

Remove and clean the diaphragm. Replace
if needed.
Leaks around

Check pipe fittings connection and glue,
repair or replace as needed
Hand tighten solenoid and bleed screw if
needed
If vacuum breaker is leaking (anti-siphon
models) remove cap, gasket, and internal
