the piping to remove accumulated dirt, pipe scale, oil, and other
contaminants before installing the unit.
A properly sized pressure relief valve should be installed after the
compressor and before any block valves. The relief valve should be
installed in compliance with any applicable federal, state, or local
codes.
To isolate the aftercooler for maintenance, install bypass piping around
the aftercooler and separator (if installed). Reference Figure 3.
Connect the inlet piping to the top of the aftercooler. Make sure that
the flexible hose is properly installed before the aftercooler inlet.
Provide supports wherever necessary to prevent stress on the
aftercooler. Supports should be installed close to the inlet and outlet
manifolds. Use either overhead or stiff-leg type supports.
4.5 FREEZE PROTECTION
If the aftercooler is to be installed in a location where ambient tempera-
tures may fall below 35oF, heat tracing and/or insulation must be used
on the outlet piping to the separator, the separator, and the drain
piping. The aftercooler must be protected from the direct wind, i.e. a
roof and/or walls.
The aftercooler should be turned off when ambient temperatures fall
below 35oF.

MAKE SURE THAT ALL USER SUPPLIED WIRING IS
PROPERLY SIZED TO HANDLE THE AMPERAGE REQUIRED
BY THE AFTERCOOLER AND ANY ADDITIONAL
EQUIPMENT.
WHEN WIRING TO THIS UNIT AND ANY OTHER
ELECTRICAL COMPONENTS, ALWAYS COMPLY WITH THE
NATIONAL ELECTRICAL CODE AND ALL APPLICABLE
FEDERAL, STATE AND LOCAL CODES.
IF THE AFTERCOOLER IS TO BE INSTALLED OUTDOORS
OR IN AN EXTREMELY HUMID ATMOSPHERE, MAKE SURE
THAT ALL WIRING AND COMPONENTS ARE PROPERLY
RATED.
VERIFY THAT THE POWER SOURCE MATCHES THE
AFTERCOOLER ELECTRICAL REQUIREMENTS BEFORE
MAKING ANY CONNECTIONS. REFERENCE EQUIPMENT
DATA TAG AND FIGURE 4 FOR INFORMATION.
TO PREVENT POSSIBLE ELECTRICAL SHOCK, IT IS
IMPORTANT THAT THIS UNIT IS GROUNDED. ALWAYS USE
THE PROVIDED GROUNDING SCREW.
The aftercooler electrical requirements are listed on the
equipment data tag and in Figure 5. If there are any discrepan-
cies between the data tag and Figure 5, use the information on
the tag.
Remove the cover from the electrical junction box on the
aftercooler motor. Using FIGURE 5 as reference, make the
necessary wiring connections. Several ways to wire the unit
are listed below. Make the connections for the pertinent
application(s).
1. DEDICATED POWER SUPPLY AND DISCONNECT
Install a properly sized fused disconnect before the
aftercooler. Make the necessary wire connections and re-
install the junction box cover.
2. INTERLOCKED WITH COMPRESSOR MOTOR STARTER
The aftercooler can be interlocked with the air compressor
starter. This allows the aftercooler to operate only when the
air compressor is operating.
If a set of auxiliary, normally open contacts is available on
the air compressor magnetic starter, make necessary wiring
connections from the contacts to the aftercooler.
If a set of auxiliary contacts is not available, use a properly
sized contactor. Wire the contactor's holding coil in parallel
with the air compressor starter holding coil. Make the
necessary wiring connections from the contactor to the
aftercooler.
4.7-1 FAN MOTOR ROTATION
The rotation of the fan motor(s) is important. Units with 3
phase power should be checked for proper rotation after
installation.
Energize the unit. Observe the rotation and air flow direction.
Reference Section 3.2 for air flow direction. If the fan(s) do
not pull the air across the core, turn off the unit and switch
two of the main power legs.
4.6 SEPARATOR INSTALLATION
CAUTION
IF THE SEPARATOR DRAIN IS TO BE CONNECTED INTO A
REMOTE OR COMMON DRAIN LINE, MAKE SURE THAT IT IS
VENTED.
THE DISCHARGE FROM THE SEPARATOR MAY CONTAIN
COMPRESSOR LUBRICANTS. COMPLY WITH ALL
REGULATIONS CONCERNING DISPOSAL OF SUCH FLUIDS.
When the system air is cooled by the aftercooler, moisture in
the compressed air condenses and accumulates in the outlet of
the aftercooler. To efficiently remove this liquid from the air
system, a separator with an FD-1 float drain must be installed
immediately downstream of the aftercooler.
Install the separator as outlined in the Installation, Operation,
and Maintenance Instructions supplied with the component. If
a separator was not ordered with the aftercooler, one can be
ordered from your VAN AIR distributor.

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.
