Connecting the Intercooler and
Optional Precooler
(W1600 - 5000)
The intercooler and/or 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}.
1 Connect the water supply line to
the intercooler or precooler 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 with the pressure
relief valve to the intercooler
or precooler outlet. Use the
bracket supplied to secure the
pressure relief valve to the back of
the dryer.
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 intercooler
assembly for cleaning.
✒
TIP: If an optional flow control is
also being installed with the inter-
cooler, the manual shut off valve
should be installed on the inlet line
for the flow control.
