Maintenance

Gas Inlet Filter Replacement

Periodically check the gas inlet filter, located directly behind the gas-inlet

fitting, for signs of dirt. As necessary, replace this filter per Figure 23.

Pump Replacement

The pump may become inoperative due to water or solid particles getting

into the valves. This will require replacement of the pump to correct.

To replace the pump (see Figure 24):

1. Remove the instrument’s bottom plate using a

/64" Allen wrench to

remove the plate’s four corner screws. Then remove plate and rubber

bumper to expose the instrument’s interior.

2. Back off the pump bracket screw in the lower corner of the flow block

and rotate bracket arm to free pump.

3. Unplug pump connector from printed circuit board and lift pump

straight out of instrument.

4. Install the new pump by lining up the pump’s inlet and outlet tubes

with the two flow block holes and pushing into place. Swing bracket

arm over pump and tighten—aligning pump as necessary.

5. Leak test pump before use per section Leak Check Basics.
