Procedure 4: Clean and Replace Polar Cool Flux Filters.

(Interval - 3 weeks)

All surfaces inside of the oven may be hot. This can include

"cool cells". Make sure that the system is safe to touch before

attempting this procedure

Each cooling cell has a removable fin type flux filter that

should be checked, cleaned and replaced periodically. Make

sure the system is cool before attempting this procedure.

Raise the main Hood. Open the hinged housing cover and

remove the heat exchanger fin assembly and properly dispose

of it or clean and reuse by soaking in a flux removing solvent

such as Isopropyl alcohol. Once thoroughly cleaned, replace

the heat exchanger and reassemble.

To remove the Cooling Cell Faceplate, rotate the Retaining

Clips and drop the Faceplate down to soak and/or wipe with

Isopropyl Alcohol. If the face plate is removed.

After releasing the cam locks, remove the "clam shell"

housing from the cell.

The aluminum flux filter is housed within an aluminum

“clam-shell” housing which is seated against the cold plate.

This assembly conducts heat to the cold-plate as well as

filters flux vapors from the oven gas.

The filters require periodic maintenance, but can be

removed cleaned and reused (There is no liquid

connection).

Clean dirty filters with isopropyl alcohol.

Note: Reverse the disassembly process to reinstall the filters

in the oven
