Cleaning the Aftercooler Coils
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.
NOTE: If an optional flow control was added with the aftercooler, remove the compres-
sion fitting from the aftercooler inlet. Loosen the fitting on the flow control, then swing
the copper water supply tube out and away from the aftercooler inlet.
3 Remove the screws securing the aftercooler in the aftercooler housing.
✒
TIP: If the aftercooler (without a flow control) was installed using the recommended
24 inch {61 cm} of flexible hoses, there is no need to disconnect the hoses from the
aftercooler inlet and outlet.
4 Remove the aftercooler assembly from the aftercooler housing.
