AirVantage Servicing -
Power Generation Module
To service the power generation module, 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”.
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 the plastic cover located on the top of the
unit. Inspect the o-ring between the poppet valve and the adapter plate for damage.
Step #3: Access the Power Generation Module
• Use a 5/32 hex-key wrench and loosen the four 10-32 x .50 socket head cap screws
• securing the bottom cover. Lift the bottom cover off, exposing the power generation module. 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 power generation module needs to be replaced, unplug the connector that connects
• the power generator to the control board. Use a 5/32 hex-key wrench to loosen the four 10-32 x 2 ¼
socket head cap screws. The power generation module should now be loose. Carefully lift the power
generation module off the rest of the assembly, making sure that the control board wire and connector
slips through the hole in the power generation case.
• "AirVantage CAUTION" - Take caution not to loosen the o-ring that seals between the
components.
Step #4: Reinstallation
• When reinstalling the new module make sure to feed the control module wire through the hole in the
power generation case. Install the four 10-32 x 2 ¼ socket head cap screws and tighten to 60 in-lbs.
• “AirVantage CAUTION” – Be sure to reattach the connector from the power generator to the
control board.
• Reinstall the bottom cover, making sure the o-ring seal is still in the groove. Tighten
• the four 10-32 x .50 socket head cap screws to 30 in-lbs.
• 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.
