Appendix A: General Maintenance (continued)
Filter Check Continued
The other two filters are located in the water trap (p/n A796). The main filter is
the A762F particle filter. This filter stops debris and dust from traveling down to
the analyzer. The secondary filter is the A794W water block filter. This filter
stops flow in the event the water trap fills with condensate. Refer to the picture
below.
Visually inspect the A762F particle filter. If the filter is discolored on the inside
or outside a replacement filter should be installed.
If the A762F is clean but saturated with water a replacement should be installed
to ensure proper flow. The saturated filter can be left to dry and reused later.
Pump Operation Check
1. Turn the analyzer on as outlined on page 5 and connect to the TPI View app.
Do not connect anything to the inlet. Turn the pump on by tapping “Start Pump”
prior to proceeding to step 2.
2. Cover the analyzer inlet with your finger. The analyzer pump should draw
down and begin to slow.
If the analyzer pump does not draw down and slow this may be an indication
the pump is faulty, or there is an internal leak. The analyzer should be returned
for factory service.
