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.
The legs can be mounted two ways:
1. Core mounted horizontally
2. Core mounted vertically

AC-10-1 & AC-20-1 .... 615 SCFM
AC-30-1 & AC-40-1 .... 945 SCFM
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.

MAXIMUM PRESSURE DROP LESS THAN 3 PSI.
* Maximum ratings restricted by pressure drop: actual thermal capacities are higher.
Determine the desired position for your installation. Place the
aftercooler in that position (horizontal or vertical). Carefully lift
and support the unit approximately 1 to 2 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.
