Automated Pressure Calibrator

Contamination Prevention System (CPS)

Disconnect the CPS

To disconnect the CPS:

1. Vent the system.

2. Disable the CPS in the settings. It is important that the CPS is disabled in the

firmware before it is physically disconnected from the system. Failure to do

so could result in the system not being able to vent pressure.

3. Once disabled in the firmware, the CPS can be disconnected both electrically

and pneumatically.

CPS Cleaning

The CPS requires periodic cleaning. To clean the CPS, see Figure 23:

1. Vent the CPS.

2. Remove the waste bottle  from the side opening of the CPS bracket and

safely dispose of the contents.

3. Drop the sump.

4. Pull down the filter assembly.

5. Unscrew the lower screen retainer  from the bottom of the filter assembly.

6. Pull out the screen  and rinse with soapy water or alcohol.

7. Inspect the coalescing filter. If saturated with oil particles, it needs to be

replaced. The coalescing filter cannot be cleaned.

8. Reverse these steps to reassemble the CPS.
