Aeroqual AQM60 User Guide
If the flow does not drop to zero it suggests there is a leak somewhere in the system. To check the pump
module:
Keep the purge line disconnected.
Remove the sample connection and cap off the module sample port.
Connect the exhaust port of the module to the pressure end of a flow meter.
The flow should drop to zero.
If there is a leak in the pump module the module will need to be sent back to the Aeroqual factory. Please
contact technical support.
If there is no leak in the pump module it is likely the leak is located in the engine. In this case, the engine will
need to be sent back to the Aeroqual factory. Please contact technical support.
7.5.4. Filter Changes
There are two green filters which are located to the left of the sample filter holder. They are designed to
provide protection to the pump and optical window. The filters will become dirty and must be replaced
periodically.
To do this, unclip the filters from the connectors and replace. Ensure the filters are connected the right way
in accordance to the flow arrow. These filters can be purchased from Aeroqual. Please contact technical
support for a quotation.
