Description

Campbell Hausfeld oil-level monitor is an accessory for two-stage air compressor
pumps. This monitor measures the level of oil in the compressor and shuts the
pump down if the level drops below a minimum. Can be used with 208-230 volt
single-phase and 208-230 volt three-phase, two-stage, cast iron Campbell Hausfeld
air compressor pumps equipped with a magnetic starter.

5. Push the oil level guard housing on
to the adapter (See Figure 2).

6. Tighten set screws in housing until
snug and then re-install oil level sight
glass on the front of the housing
(See Figure 3).

ELECTRICAL INSTALLATION

Always disconnect, lock­out and tag power
before attempting to
install, service, relocate
or perform any maintenance.

Use the diagram in Figure 4, 5 or 6 to

Operating Instructions and Parts Manual

Low Oil Guard
for 5 to 25 HP Compressors

Installation (Continued)

guard must be tested to verify proper
installation. Before refilling crankcase
with oil, briefly turn on power to the
compressor motor (2-3 seconds max.).

NOTE: Some oil film remains on the lu­bricated parts of the compressor.
Running the compressor dry for 2-3 sec­onds will not cause any damage.

If motor does not run, installation is
correct. If motor begins to run, turn
power off immediately. The installation
is wrong and the following items
should be checked:

1. Check for loose wire connections.

2. Check for wrong wiring (Refer to
Figure 4, 5 or 6).

3. Check to see if the float mechanism is
moving freely.

4. Check the compressor for a level
position.

After the monitor installation has been
tested and found correct, refill the com­pressor pump with compressor oil. For
complete information on compressor
pump oil, see your compressor pump
manual.

TF0628

Operation

In normal operation, the low oil-level
monitor should not have any effect on
the performance of the compressor. If
the oil level in the pump is too low, the
monitor will shut off power to the
motor, stopping the compressor pump.

Maintenance

The operation of the low oil-level mon­itor should be checked at every oil
change. After the oil has been drained
from the crankcase, repeat the initial
test as previously described.
