The aftercooler coils will need to be kept clean to keep the aftercooler working
efficiently. Cleaning frequency depends on the type and amount of material you
process.
1
Stop the dryer and lockout the main power.
2
Turn off the water flow to the water supply line. Disconnect
supply and return lines.
i
NOTE: If an optional flow control was added with the aftercooler, remove the compres-
sion fitting from the aftercooler. Loosen the fitting on the flow control, then swing the
copper water supply tube out and away from the aftercooler.
3
Remove the two (2) nuts securing the aftercooler in the housing.

TIP: If the aftercooler (without a flow control) was installed using the recommended
24 inches {61 cm} of flexible hoses, there is no need to disconnect the hoses from the
aftercooler inlet and outlet.
4
Remove the aftercooler from the aftercooler housing.
5
Clean the assembly using a mild soap and water. Let the assembly dry
thoroughly before installation.
6
Inspect the condition of the gasket. If it is damaged, replace the gasket.
7
Reassemble by repeating the steps in reverse order.
8
Connect the water supply line to the inlet. If a manual shut off valve is used, it
should be mounted on the inlet line as well.
9
Connect the outlet of the aftercooler to the inlet of the flow control valve using
the pre-shaped copper tubing and compression fittings provided.
