heat exchanger at the top of the unit. The air-cooled unit with the standard enclosure requires sufficient
flow, Figure 2-2, page 6, for the compressor water/aftercooling system and for electric motor cooling. Do
not block the air flow to and from the unit. Allow three and one-half (3-1/2) feet to the nearest obstruction
on the control box end of the unit. Allow three (3) feet to the nearest obstruction above and on other
sides of unit. For continuous efficiency, the heat exchanger and aftercooler cores must be periodically
cleaned with either vacuum or compressed air. If wet cleaning is required, shield the motor and spray on
a mild soap solution, then flush with clean water.
