Valve can be set for time between openings with any valve time open.
Power supply 120 volt single phase.
To change times, remove six socket head cap screws, lift off cover and reset
switches as required.
To check proper functioning of the printed circuit board and to manually operate
valve, press and release manual override on side of housing. Valve will open and
remain open for the set opening time. Valve will then close and timer will start a
new cycle.
If the manual override is pressed and valve does not turn, the circuit board may be
defective and should be replaced or repaired at the factory.
