Before filling the system with solvent, be sure that you have checked for leaks, the refrigeration system is on, all drain valves are closed, and drain plugs are installed. Be sure the cooling media is flowing through the condensing coils. Fill the non-boiling sump to the top of the divider and allow solvent to overflow into the boiling sump until the level is approximately 2” from the top of the divider.

After the machine is turned ON and the spray reservoir fills with clean condensate, additional solvent will need to be added to the boiling sump to bring the level back up. The solvent level in the boiling sump should be maintained at least 2” above the heating elements at all times.

Bleed off water from the water separator daily. While the degreaser is operating, partially open the purge valve and collect the overflow into a container. Since this water contains some solvent, it must be disposed of in accordance with local regulations.

Until the heat switch is turned ON, the refrigeration system will cycle to maintain an air temperature of approximately 50°F in the freeboard area above the solvent. After turning the heat on, the solvent vapors will rise, and the refrigeration system will run continuously to maintain a constant vapor height.

Cleaning may begin as soon as the boiling sump starts boiling, and the condensed vapors are dripping off the condensing coil. For ease of handling, large parts may be placed in the cleaning tank directly with long handled hooks or tongs, while small parts are best placed in a basket. Stainless steel baskets are recommended. If a basket is used, rack the parts for maximum drainage and minimum solvent entrapment. Best cleaning will result when the number of parts being cleaned at one time is kept at a minimum.

Lower the work into the boiling sump slowly, at a rate not to exceed 11 feet per minute, a greater rate will disturb the vapors and cause excessive solvent loss. Allow parts to sit in the vapors until condensation off the parts ceases. The exact time will depend on the kind and amount of contamination and the size and construction of the part, and is best determined experimentally.

Transfer the work slowly into the clean solvent sump to rinse for several minutes. While moving the part(s) from sump to sump, never bring work above the vapor line. If the clean solvent tank is equipped with ultrasonics, additional surface cleaning will take place. The work can then be raised into the solvent vapor for a spray rinse, if desired, and a final vapor rinse.

After completing the cleaning operation, the stainless steel cover should be moved into place to conserve solvent whether the boiling sump is ON or OFF.
