Install the Exhaust Pressure Module on the pump
When the Q Series 3 Exhaust Pressure Module is installed in the frame of the QDP pump, the
Exhaust Pressure Module inlet-purge and exhaust-purge nitrogen outlets are designed to align
and engage with the nitrogen pipelines on the pump. Figures 5 and 6 show the location of
components of the Exhaust Pressure Module. Where necessary, refer to the instruction manuals
supplied with your QDP pump and your QDP Gas Module.
Use the procedure below to fit the Q Series 3 Exhaust Pressure Module.
1.
Switch off the pump, if it is in use.
2.
Remove the two blanking plugs from the inlet-purge and exhaust-purge nitrogen pipeline
terminations on the QDP pump.
3.
If there is a restricted bulkhead fitting (identified by an external O ring) in the exhaust purge
pipeline, replace the fitting with the unrestricted bulkhead fitting supplied in the fitting-kit.
4.
Align the Exhaust Pressure Module in the pump frame. Make sure that the exhaust-purge
and inlet-purge nitrogen pipeline terminations on the back of the Exhaust Pressure Module
(Figure 6, items 2 and 3) are in-line with the nitrogen pipelines on the pump.
5.
Use the two screws supplied to secure the Exhaust Pressure Module in position.
6.
Tighten the inlet-purge and exhaust-purge nitrogen pipeline connectors.
7.
Fit the connecting pipe supplied to the exhaust-purge inlet on the Exhaust Pressure Module
(Figure 6, item 4) and to the auxiliary nitrogen outlet on the QDP Gas Module. This pipe
passes through a cut-out in the gas services panel.
