•   The valve must not be operated continuously for more than 12 hours in
any 24-hour period.
•   Installing a manual shut-off valve between the main water supply and
automatic valve or valve manifold is recommended for ease of valve
maintenance and sprinkler system winterization.
Installation Procedure
Figure 1
1.
From the shut-off valve, route a supply  pipe to the valve
installation site. For UV protection, use dark  gray
Schedule 80 PVC on the inlet (pressurized)  side of the
valve and all PVC pipe installed above  ground. Use
Class 200 PVC on the underground sprinkler  lines.
Slip x Male Thread
PVC Adapters

3.
Flush the supply line thoroughly to remove  all traces of
dirt and debris.
6"
(minimum)
Prepare two 1" slip/male thread adapters with three to five
complete wraps of teflon tape, evenly covering the threads.

Install the threaded adapters into the valve and tighten
securely. Using PVC primer and cement, install the valve to
the PVC pipe as shown in Figure 1.

Route a multi-wire, direct-burial sprinkler valve cable
from the sprinkler timer to the valve  location. If the cable
run is less than 800', 18-gauge wire  is sufficient. For dis-
tances from 800'2000', 14-gauge wire is recommended.
6.
Using wire splice connectors, attach either wire  from
each valve solenoid to the white cable  wire. This wire is
designated as the valve common wire. Connect  the
remaining wire from the solenoid to one  of the color-
coded cable wires. Ensure all wire connections  are
secure and waterproof.

CAUTION: Use grease caps or waterproof connec-
tors on all wire splice connections to prevent corrosion,
connection failure and short circuit.

At the sprinkler timer, connect the  white common wire to
the output terminal labeled Cor COM.”  Connect each
color-coded valve wire to the numbered output
terminals in the order you wish the  valves to operate dur-
ing the automatic watering cycle.
Open the shut-off valve from the water  source. Test valve
operation using the timer or manually at  the valve.
