Connecting the Aftercooler
The aftercooler and optional precooler require a source of cooling water and a
discharge or return line.
To connect water hoses:
1 Connect the water supply line to the
aftercooler inlet. If a manual shut off
valve is used, it should be mounted on
the inlet line.
2 Connect the water discharge or return
line to the aftercooler outlet.
✒
TIP: Make the water supply and
discharge / return connections
with flexible hoses at least 24 in.
(61 cm) long. This allows you to
easily remove the aftercooler
assembly for cleaning.
✒
TIP: If an optional flow control is
being installed to the aftercooler,
the manual shut off valve should be
installed on the inlet line for the flow
control.
NOTE: Water to aftercooler should be turned off when the dryer is not running to
prevent condensation.

✒
TIP: To ensure that the aftercooler’s
copper piping is not damaged or
pinched while installing an adapter,
use a wrench to brace the aftercool-
er piping.
