Maintaining the Forepump

Cleaning the Fan Filters

Thermo Scientific
The forepump is located under the TSQ mass spectrometer work table. Inspecting, adding,
purging, and changing the oil are all that is required to maintain the forepump.
Forepump oil is a translucent, light amber color, which you must check often. During normal
operation, oil must always be visible in the oil level sight glass between the MIN and MAX
marks. If the oil level is below the MIN mark, add oil. If the oil is cloudy or discolored, purge
the oil to decontaminate dissolved solvents. If the pump oil is still discolored, change it. Plan
to change the pump oil after every 3000 hours (about four months) of operation. Refer to the
manufacturer's documentation for procedures for purging, adding, and changing the
forepump oil.
You must clean the two fan filters every four months. The fan filters are located on the of the
front cover and on the right side cover of the TSQ Series mass spectrometer.
 To clean the fan filters
1. Remove the fan filter from the right side cover:
a. On the TSQ Vantage, using a Phillips screwdriver, remove the six screws that hold
the blue appliqué to the right-side cover.
b. Remove the appliqué.
c. Loosen and remove the four screws that hold the filter bracket to the right-side cover.
Note that from the outside of the mass spectrometer the filter bracket appears to be a
grille.
d. Remove the filter and filter bracket.
2. Remove the fan filter from the front cover:
a. Remove the front cover of the TSQ mass spectrometer:
i. Disconnect all tubing to the divert/inject valve and syringe pump.
ii. Depress the two (blue) spring catches that are located on either side of front
cover.
iii. Pull the front cover straight off by about 6 in. (15 cm) to access the Front Panel
PCB cable and the two grounding wires.
iv. Disconnect the Front Panel PCB cable from the TSQ mass spectrometer by
pushing the connector retainer up and then pulling the cable free.
