3-Way Solenoid – Confirm that the manual operator is turn counter clockwise to a full OUT position (See Figure 1).
STEP 2
Energize the solenoid to check actuation and to confirm connec-
tion to power source.
STEP 3
De-energize the solenoid prior to initial pump start.
STEP 4
Loosen a tube fitting or cover plug at the main valve to allow air to
