NOTE:
The WR1220 110 volt solenoid valve is normally closed (N/C). When bypass lever on the valve housing is closed—Step 2 below—, solenoid must be
energized to allow water to flow. Inlet pressure must be 15 psi greater than the regulated outlet pressure to allow the valve to fully close during operation.

Setting the WR1220 110 VAC Solenoid Valve
2. Rotate the bypass lever to the
7 o'clock or 5 o'clock position to
close the valve.
3. Turn on main water to supply
water to each WR1220 valve.
4. At the first valve, move the
bypass lever to 12 o'clock to
allow water to flow into the valve.
1. With the water turned off,
move to
each WR1220
and turn butterfly
valve clockwise until fully closed.
Do not overtighten.
Photos above identify the different parts of the WR1220 solenoid valve.

5. Turn butterfly valve counter-
clockwise and set the desired
water pressure (20 psi – 45 psi).
ATTENTION:
To prevent damage
to the drippers, water pressure
should not exceed 45 psi.
6. With the pressure at the desired
setting, close the bypass lever by
rotating it to either the 7 o'clock
or 5 o'clock position.
ATTENTION:
During system
operation bypass lever is closed.
7. Move to the remaining WR1220
valves and repeat steps to adjust
pressure setting at each.
8. Return to Procedure 10 (previous
page) and continue with Step 6.
