STEP 1

Pre-set pilots as noted:

Pressure Reducing

 - Adjust OUT, counterclockwise, backing pressure off the spring, preventing possible over-pressuring of the system.

Opening and Closing Speed 

– Turn the adjustment screws on the Closing Speed and Opening Speed Controls, if the main valve is so 

equipped, OUT, counterclockwise, 11/2 to 21/2 turns from full closed position.

STEP 2

Energize the solenoid to check actuation and to confirm connection to power source.

STEP 3

De-energize the solenoid for initial valve filling.

STEP 4

To ensure proper operation, any trapped air will need to be bled off 
the valve cover during startup. If your ACV includes a bleed valve, 
use a flat head screwdriver to slowly open the valve.

If your valve does not include a bleed valve, bleed air by loosen-
ing a fitting on the valve or a plug, at the highest point of the valve 
assembly (See Figure 1).

STEP 5

Pressure the line, by opening the upstream isolation valve slowly 
Air is vented through the air bleed valve or loosened fitting. Tighten 
the fitting when liquid begins to vent (See Figure 1).

Repeat the process until no air is trapped in the system.
