AirVantage Servicing -

Solenoid Valve and Pressure Regulator

To service the solenoid valve or the pressure regulator, first shut off and bleed the air being supplied to

the pump. For safety purposes the air supply line should be disconnected from the pump. Then shut off the

suction and discharge lines to the pump. Bleed the pressure from the pump suction and discharge lines and

remove the lines from the pump. During the servicing of the AirVantage, consult the “AirVantage Composite

Repair Parts Drawing”. (page 14)

Step #1: Remove the Patch Cable

• Twist the ribbed portion of the patch cable connector in a counterclockwise direction, until it unthreads

from the connector. The cable can either be removed from the intermediate or from the control module.

Step #2: Remove the AirVantage from the Pump

• Use a ½” socket and remove the four 5/16-18 x 5

cap screws that hold the AirVantage to the pump.

Be sure to support the weight of the AirVantage while removing the last cap screw. After the AirVantage

is removed from the pump, set the unit down on bottom cover. Inspect the o-ring between the poppet

valve and the adapter plate for damage.

Step #3: Access the Solenoid Valve and Pressure Regulator

• Use a 5/32 hex-key wrench and remove the four 10-32 x .50 socket head cap screws securing the top

cover on. Lift the cover off, exposing the solenoid valve and pressure regulator. There is a molded o-ring

seal located on the underside of the cap. Make sure the o-ring stays located within the groove.

• If the solenoid valve needs to be replaced, unplug the connector attached to it. Use a miniature 4-way

Phillips screwdriver and remove the two screws holding the solenoid valve to the plate. The valve and

gasket can now be removed and/replaced. When reinstalling the solenoid valve, tighten the screws to

snug with a miniature 4-way Phillips screwdriver.

•

“airVantage caution” – Be sure to reattach the connector to the solenoid valve.

• If the pressure regulator needs to be replaced, use slip-joint pliers to unscrew the regulator from the

body by turning it in a counterclockwise direction.

•

“airVantage caution” – Do not loosen or tighten the regulator by turning the knurled portion

of the unit. Place the slip-joint pliers on the smooth area underneath the knurled area of the

regulator.

Step #4: Reinstallation

• Reinstall the top cover, making sure the o-ring seal is still in the groove. Tighten the four 10-32 screws.

• Reinstall the AirVantage using the four 5/16-18 x 5

cap screws and torque to 90 in-lbs.

•

“airVantage caution” – Be sure to reattach the patch cable connector that connects the

airVantage module to the intermediate.
