Air-Cooled Units - A combination oil/aftercooler is supplied as standard equipment on all air-cooled
units. The air-cooled unit with the standard enclosure requires sufficient flow, Figure 2-2, for the
compressor oil/aftercooling system and for electric motor cooling. Air is drawn into the unit at the motor
side of the enclosure and is exhausted at the oil cooler side. Do not block the air flow to and from the
unit. Allow 1.1m to the nearest obstruction on the starter end and control box end of the unit. Allow .9m
to the nearest obstruction above and on other sides of unit. For continuous efficiency, oil cooler cores
must be periodically cleaned with either vacuum or compressed air. If wet cleaning is required, shield
motor and spray on a mild soap solution and flush with clean water.
Water-Cooled Units - The water-cooled unit with the standard enclosure requires sufficient air flow,
Figure 2-2, page 17, for electric motor cooling. Air is drawn into the unit at the top of the enclosure and is
exhausted at the motor side. Do not block air flow to and from unit. Allow 1.1m to the nearest obstruction
on the starter end and control box side of the unit. Allow .9m to the nearest obstruction above and on
other sides of the unit.
