Setting the Altitude Controls
STEP 1
Pre-set pilots as noted:
Altitude Control
– Adjust OUT, counterclockwise, backing pressure off the spring. This simulates a low tank setting which can be
gradually increased to the desired setting.
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, 1
½
to 2
½
turns from full closed position.
STEP 2
Energize the solenoid to check actuation and to confirm connection
to power source and so that initial valve filling is against the closed
solenoid.
NOTE:
In cases when testing is required prior to electrical
installation the solenoid can be manually engaged using the manual
override red knob on the end of the solenoid.
STEP 3
To ensure proper operation, any trapped air will need to be bled off
the valve cover during startup. The ACV includes a bleed valve, use
a flat head screwdriver to slowly open the valve (See Figure 1).
STEP 4
Pressure the line, by opening the upstream isolation valve slowly. Air
is vented through the air bleed valve. Tighten the fitting when liquid
begins to vent (See Figure 1).
Repeat the process until no air is trapped in the system.
STEP 5
Switch the solenoid to the open position (de-energize solenoid).
