Installation; Solenoid And Valve Installation - DIG LEIT-2 Operating Instructions Manual

STEP 4: After setting up the controller, program the controller (See RC2
handset operating instruction)
The handset and controller should now be available for communication

2.1 Solenoid and Valve Installation

NOTE: Maximum operating pressure is up to 150 PSI (10.5 bar)
Use DIG's 305DC-XXX valve-assembly or Model S-305DC solenoid and select
the appropriate conversion adaptor for the valve(s) that will be used with the
S-305DC solenoid (see list 1.2 #4 on Page 8).
1. Shut off the mainline to the valve.
2. Install valve assembly (model 305DC-XXX) or unscrew the conventional
solenoid from the valve installed and remove the solenoid housing, solenoid
stem, plunger, spring, and "O" ring (if necessary).
3. Select the appropriate conversion adapters for the valve(s) (see list above in
1.2 #4 on pages 8)
IMPORTANT:
Do not remove existing "O" ring on BUCKNER and SUPERIOR
valves. When installing adaptor on BUCKNER and SUPERIOR valves remove
the adapter sleeve (model 30-424) before installing.
4. Thread and tighten the conversion adapter clockwise to the compatible
valve port, do not over tighten (no tools necessary) (see a).
5. Make sure that the solenoid holder/handle is not inserted onto the solenoid
housing and then, screw model S-305DC solenoid into the selected adapter.
Firmly tighten the solenoid by hand, but do not over tighten (see b).
6. Slip the manual handle into the solenoid housing. Positioning the solenoid
handle at a 40-45° angle towards the valve creates a manual lever; helpful
for manual on/off (see b1-c).

7. After installation is complete, turn the water supply on and pressurize the
mainline. The valves will open momentarily and then shut off. Test each
valve in manual operation by moving the manual handle from left to right to
open and right to left to close the valve, making sure that the valve is
operating correctly.
8. Splice the solenoid hot wires (red) to the controller incoming station wire
(V1 red). Splice the solenoid white wire to the single incoming white wire
(V1). If needed repeat for the second valve. Use 2 conventional dry-splice
waterproof connectors. Leave slack on each side of the
wires so that repairs can be carried out easily.
NOTE: The solenoid operates only with
2-way normally closed valves.
NOTE: V1 may be identified by label or striped wires.
IMPORTANT:
If a valve remains open in manual operation, you may need to
examine the solenoid adaptor and sleeve to see that they are installed
correctly and the adaptor is firmly secured. Do not over tighten the solenoid to
the valve and do not cross thread the adaptor into the solenoid cavity.
CAUTION:
For all valves with built-in internal manual bleed lever, make sure
the lever is in closed position. Do not move the lever after installing the
solenoid with the valve adapter. If the manual lever on the valve is used, it can
damage the adapter or the sleeve causing the valve to stay open.
