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.
Step #2: Remove the AirVantage from the Pump
Use a ½” socket and remove the four 5/16-18 x 5 1/2 cap
screws that hold the AirVantage to the pump. Remove the two
chamber bolts/nuts that are holding the right side bracket to be
able to remove the right bracket and AirVantage unit from 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 bottom. 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
right bracket, chamber bolts/nuts and four 5/16-18 x 5 1/2 cap
screws, torque to 90 in-lbs.
“AirVantage Caution” – Be sure to reattach the patch cable
connector that connects the AirVantage module to the
intermediate.
