TEST FUNCTION

To verify valve operation, or to manually discharge uid, turn the "CLOSED TIME" knob counter clockwise until it stops in the area labeled "TEST". The valve will open for the set "OPEN TIME". After the valve closes, it will automatically repeat the test in 2 seconds unless the "CLOSED TIME" knob is reset to its regular position.

REQUIRED MAINTENANCE

The integral strainer must be cleaned periodically to ensure proper valve performance. The time between cleanings will vary depending operating conditions. Remove cap to access screen for cleaning. (Reference Figure 2).
