3.2.3 Loss of air output pressure
If the garments do not inflate, check them for leaks and for the correct
connection of tubesets.
If the leak check is satisfactory the pump unit internal compressor must be
tested.
Switch OFF pump unit and disconnect the supply cord from the power
outlet.
1. Remove unit lid as described in Section 5.
2. Disconnect the compressor outlet tubes from the 4-way connector and
connect a Y-piece to the two tubes.
3. Connect a pressure gauge to Y-piece outlet.
4. Reconnect the power supply cord and switch on the pump.
The pressure reading should be at least 100 mmHg.
If the pressure does not reach 100 mmHg, disconnect the power supply again
and remove the compressor lid. Remove the silencer bag from the valve bodies
and connect the pressure gauge to each valve body in turn. The pressure
reading should once again be approximately 100 mmHg.
If this pressure cannot be reached, the bellow/armature assemblies and valve
bodies must be replaced. If 100 mmHg can be obtained, the silencer bag
assembly must be replaced.
Switch OFF the pump unit and disconnect the electric cord from the
power outlet before performing any repair work.
