Aeroqual AQM60 User Guide
The TSP inlet can also be dismantled by unscrewing the 3 screws and separating the head into two parts.
Use a lint-free cloth wetted with isopropyl alcohol to clean both the inside and outside of the inlet.
7.4.10. Pump Module Removal
The pump module can be removed by unscrewing the 4 screws on the base plate and sliding the module
out. Ensure the AQM is switched off when removing the module. The sample, purge and exhaust lines need
to be disconnected and all the connected cables removed. The two main failures which would require
removal of the pump module are:
1. A leak is discovered
2. The pump requires replacement
In both these cases the pump module will need to be sent back to the Aeroqual factory for repair. Please
contact technical support for assistance.

7.5.1. Sample Flow Check and Adjustment
A set flow rate is essential to ensure consistency in the measurement. To measure the flow, remove the TSP
head and connect the volumetric flow meter to the top of the inlet using the adaptor supplied with the
instrument. Ensure the flow meter is on a steady surface before reading the flow rate.
Note 1: The adaptor tubing should be connected to the TOP of the volumetric flow meter (negative
flow)
Note 2: The flow should be 1.0 LPM
The inlet flow can be adjusted via the flow adjuster on the exhaust line.
If the flow is
greater than
1.0 LPM then
close the exhaust flow screw
(turn clockwise) until 1.0
LPM is achieved.
If the flow is
less than
1.0 LPM then
open the exhaust flow screw
(turn anticlockwise) until the
flow is 1.0 LPM.
