Cleaning  the  Precooler  Coils

You need to clean the precooler coils to keep them 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.

3

Remove the bolts securing the precooler cover.

Remove the cover.

4

Remove the precooler by pulling it out 

of the precooler housing.

5

Clean the assembly using a mild soap and water.

Let the assembly dry

thoroughly before installation.

NOTE:

In cases of heavy volatiles, steam cleaning or the use of solvents, such as ace-

tone, may be necessary.  Be sure to test a small area with the solvent you have select-
ed to be sure there is no adverse reaction.

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 precooler to the inlet of the flow control valve

using the pre-shaped copper tubing and compression fittings provided.

NOTE: 

If an optional flow control was added with the precooler, remove the compression

fitting from the precooler inlet.  Loosen the fitting on the flow control, then swing the
copper water supply tube out and away from the precooler inlet.
