STEP 1
Pre-set pilots as noted:
Pressure Sustaining – Turn Sustaining Control adjustment screw OUT, counterclockwise, backing pressure off the spring, to allow it to stay
open while adjusting the other controls.
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 so that initial valve filling is against the
closed solenoid.
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 (See Figure 1).
If your valve does not include a bleed valve, bleed air by loosening
a fitting on the valve or a plug, at the highest point of the valve as-
sembly.
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.
STEP 6
Actuate the solenoid to the open the main valve.
