Drain Drive Air Filter Bowl
W
Warning
To prevent personal injury, do not open the tap on the filter bowl with the system at full
pressure.
When there is visible liquid accumulation, open the tap (
R
) on the filter bowl (
L
) and drain the liquid. Reduce
pressure before you open the tap. Replace the filter element when it is visibly dirty.
Troubleshooting
General Information
Note
Numerical references in this section refer to Table 5 and 6, depending on the model.
Several predictable problems can arise with Product booster package use. They are described and addressed in this
section.
W
Warning
Fluke Calibration recommends that those performing troubleshooting procedures
described in this section become familiar with the system. Please see the introductory
WARNING,
Installation
, and
Operation
for important information.
Booster Will Not Run
The booster is a pneumatically-operated pump. The reciprocating action is caused by an imbalance of forces within
the pump due to the opposing drive air pressure and the test gas supply that is being boosted. If the booster does
not operate, it means that all forces are equal or that the pistons are seized.

Check that the booster drive shutoff valve (
D
) is open. If not, fully open the valve.

Check that drive air pressure supply is actually present at the DRIVE port (

). If not, ensure gas is supplied at
the proper pressure and flow value (see
Site Requirements
).

Check that the booster drive adjust regulator (

) is set to a pressure of 0.15 MPa (20 psig) or higher and that
minimum drive air flow requirements are met (see
Site Requirements
).

Check that the high-pressure adjust regulator (
F
) is not closed. If closed, set it to the desired pressure; see
Setting High Pressure Output Equal to or Less than the Supply Pressure, Increase Pressure or Setting High
Pressure Greater than the Supply Pressure, Increase Pressure.

Check that there are no gas leaks in the drive air circuit. Repair any leaks.

Check that gas is not continuously venting from the booster exhaust muffler (
N
). If gas is venting through the
muffler, see
Gas Continuously Vents Through Exhaust Muffler.

Check that the booster is not in a stall state. If booster is stalled, determine reason and remedy. A stall state
occurs when the pressure in the high-pressure section of the booster is equal to the pressure in the low-
pressure section times the booster ratio (152:1). A stall can only occur if the high pressure circuit is plugged.
