ASSEMBLY, LEG INSTALLATION SECTION 2
2.1 INSTALLING THE LEGS
This unit was shipped without the legs installed. The legs should be
installed before placing the aftercooler in the piping system. Carefully lift
and support the unit several feet from the floor.
Position the legs against the unit and fasten them in place using the
fasteners provided. Make sure the fasteners are tightened in place.

MAXIMUM CAPACITY (SCFM)
Rated capacities are based on the following conditions: Inlet and approach temperature at inlet pressures 80 to 125 PSIG.
Approach Temperature: The number of degrees above the temperature of the cooling medium (in this case ambient air) to
which the aftercooler reduces the compressed air. A higher approach does not mean better performance.
