INSTALLATION SECTION 4
4.1 LOCATION
CAUTION
DO NOT LOCATE THIS AFTERCOOLER WHERE
PERSONNEL MAY CONTACT THE INLET PIPING
UNLESS THE UNIT IS PROTECTED BY WARNING
SIGNS AND/OR A BARRIER. DURING NORMAL
OPERATION, THE INLET PIPING MAY BECOME
EXTREMELY HOT (150
O F TO 400 O F). CONTACT MAY
RESULT IN SERIOUS PERSONAL INJURY.
DO NOT INSTALL THIS UNIT IN AN ENVIRONMENT OF
CORROSIVE GASES OR CHEMICALS. MAKE SURE
THAT THE MATERIALS USED IN THIS UNIT (listed on
page 2) ARE COMPATIBLE WITH THE ATMOSPHERIC
CONDITIONS.
The aftercooler should be located far enough away from the
compressor so that there are no vibrations transmitted from the
compressor. A FLEXIBLE HOSE MUST BE INSTALLED IN
THE PIPING TO VALIDATE THE WARRANTY AND TO
PREVENT DAMAGE TO THE AFTERCOOLER FROM
VIBRATION IN THE PIPING! REFERENCE Section 4.3 for
instructions.
The location should be level and capable of supporting the
aftercooler and all components and piping to be installed. The
aftercooler must be level to allow proper drainage of fluids from
the outlet manifold.
The aftercooler must be installed at least 1 foot from walls or
obstructions. It is important for the unit to have an adequate
air supply for cooling at all times. If more than one unit is to be
installed in the same area, allow at least 1 foot between them.
This unit must be installed indoors. If the unit is to be installed
in an area where ambient temperatures can fall below 35
o F,
precautions must be taken to prevent freeze-up and damage to
the unit. The drain lines and separator must be heat traced
and/or insulated and the unit should be protected from the
wind. REFERENCE Section 4.5 for details.
4.2 MOUNTING THE UNIT
After selecting the proper location as outlined above, the
aftercooler should be mounted to the installation surface.
Mounting holes are provided on the leg support braces.
Reference Section 3.2, on page 3 for mounting hole locations
and dimensions.

mounting holes.
4.3 FLEXIBLE HOSE INSTALLATION
IMPORTANT
A FLEXIBLE HOSE MUST BE INSTALLED BETWEEN
THE COMPRESSOR AND AFTERCOOLER TO
VALIDATE THE WARRANTY ON THE AFTERCOOLER.
The flexible hose must be installed perpendicular to the
direction of vibration from the compressor.
If a flexible hose was not ordered with the aftercooler, one can
be ordered from your Van Air distributor. Figure 2 lists the
hose required for each aftercooler model.
4.4 PIPING INSTALLATION
CAUTION
ALL PIPING MUST BE ADEQUATELY SUPPORTED
AND ISOLATED FROM VIBRATION. EXCESSIVE
STRESS OR VIBRATION IN THE PIPING WILL CAUSE
DAMAGE TO THE AFTERCOOLER CORE.
TO ENSURE PROPER OPERATION, MAKE SURE THAT
THE INLET AND OUTLET PIPING ARE CORRECTLY
CONNECTED TO THE UNIT. REFERENCE FIGURE 3.
If the aftercooler is to be installed in an existing piping system,
clean 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 inlet of the aftercooler, reference
Section 3.2 for location. 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.
