5.1 START UP INSTRUCTIONS
Pressurize the compressed air system. If the aftercooler was
interlocked with the compressor, the aftercooler will begin to
operate immediately. If the aftercooler was wired on a sepa-
rate electrical source, turn on the source.
Open the inlet and outlet isolation valves on the aftercooler (if
installed). Close the bypass valve. The aftercooler is ready for
operation.
5.2 OPERATING INSTRUCTIONS
The operation of the aftercooler is simple. The fan rotates,
moving ambient air across the core. The ambient air flow cools
the compressed air inside the core. The aftercooler will
automatically operate as long as electrical power is supplied to
the unit.

5.3 SHUT DOWN INSTRUCTIONS
To shut down the aftercooler, turn off the electrical power
source. If the aftercooler was interlocked with the compressor,
the aftercooler will automatically turn off with the compressor.
Open the bypass valve and close the inlet and outlet isolation
valves (if installed).

6.3 MOTOR LUBRICATION
This unit is equipped with a sleeve bearing motor. The sleeve
bearings will require lubrication at least every 6 months. Add a few
drops of S.A.E. 20 oil to each bearing.
6.0 MAINTENANCE INSTRUCTIONS
WARNING
BEFORE STARTING INSTALLATION OR MAINTENANCE
PROCEDURES, TURN OFF ELECTRICAL POWER AND
COMPLETELY DEPRESSURIZE THE UNIT. FAILURE TO
HEED THIS WARNING MAY RESULT IN SERIOUS PERSONAL
INJURY AND/OR DAMAGE TO THE UNIT.
NEVER REMOVE, REPAIR, OR REPLACE ANY ITEM ON THIS
UNIT WHILE IT IS UNDER PRESSURE.
NEVER REMOVE THE FAN GUARD WHILE THE
AFTERCOOLER IS OPERATING. PERSONAL CONTACT
WITH THE ROTATING FAN BLADE MAY RESULT IN
SERIOUS PERSONAL INJURY.
6.1 CORE EXTERIOR CLEANING
The core should be regularly cleaned. Accumulation of dirt or other
contaminants such as oils will greatly reduce the efficiency of the
aftercooler.
Normal accumulation of dirt can be removed by blowing off the core
with compressed air. If the core becomes contaminated with oil-laden
particles, it can be steam cleaned. Clean with extreme care. The
aluminum fins can be easily damaged.
6.2 CORE INTERIOR CLEANING
If the compressed air system contains excessive lubricating fluids,
build-up may occur. The interior of the core may be cleaned to
remove the deposits by circulating a mild cleaning solution through the
core. For most conditions, a mild alkaline solution such as OAKITE or
equal, is satisfactory. For extreme conditions, it might be necessary
to use a weak solution of INHIBITED hydrochloric acid.
Turn off the electrical power supply, depressurize the unit, and
disconnect it from the air system. Circulate the solution through the
core until it is clean. Make sure that the core is rinsed out thoroughly
before returning the unit to service.
When the core is cleaned, it is important that the full characteristics of
the fouling material and cleaning agent be known. Proper care must
be taken when handling and disposing of the solution. Always follow
the instructions supplied with the material.
CAUTION
NEVER USE SOLVENTS CONTAINING STRONG ACID OR
ALKALINE BASES TO CLEAN THE CORE. DAMAGE TO THE
CORE MAY OCCUR.
