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 (150OF TO 400OF). 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 the previous page) 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.

PRINTED IN THE U.S.A. PAGE 3

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 can be installed indoors or outdoors. If the unit is to be installed outdoors or in an area where ambient temperatures can fall below 35oF, precautions must be made 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 for mounting hole locations and dimensions. Use hardware (not supplied) sized for the mounting holes.
