Connecting the Aftercooler (Optional)
The aftercooler and optional precooler require a source of city, tower, or chiller
water and a discharge or return line. You can use water at temperatures of 45 to
85°F {7 to 29°C}. But the water flow should be at least 3 gal/min {11.4
liters/min}. See Appendix B for installation and water connection instructions for
the optional precooler.
1 Secure the aftercooler assembly in the
aftercooler housing using the six screws.
2 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.
3 Connect the water discharge or return
line to the aftercooler outlet.
IMPORTANT: Turn the water off when the dryer is not in use to prevent
condensation.
✒
TIP: Make the water supply and dis-
charge / 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 also
being installed with the aftercooler,
the manual shut off valve should be
installed on the inlet line for the flow
control.
