Cleaning - Coolant Filter
The Cooling Unit contains a screen-type filter
contained within the in-line strainer assembly.
This filter is attached to the Cooling Unit chassis.
To prevent restricted coolant flow and over-
heating of the anode, perform this inspection and
cleaning procedure every month.
1. Release the four latches that fasten the top
cover to the Cooling Unit, then lift the cover off the
unit. Remove the ten screws from the top plate,
and the four bolts from the bottom of the case. Lift
the entire Cooling Unit chassis from the protective
case.
2. Unscrew and remove the cap nut from the
strainer assembly (expect coolant solution to seep
out while the cap is removed). Lift the
filter/strainer out of the assembly, and quickly
replace the cap nut to stem the flow of coolant
solution.
3. Remove contaminants from the filter with a
solution of warm water and mild detergent. The
screen is made of delicate material and can be
deformed quite easily. Handle the filter with
extreme care.
4. Rinse the filter in clean, warm water to remove
excess detergent. Remove the cap nut and re-
install the filter. Replace the cap nut and tighten.
5. Add coolant solution to the reservoir to
compensate for spillage that occurred during
cleaning. Clean any coolant solution from the
chassis that leaked out during this procedure.
Install the chassis into the protective case.
6. Attach the twin hose assembly between the
Cooling Unit and the Tube Head, and the Control
Unit to the Cooling Unit. Apply power, and allow
coolant to circulate for three minutes. Re-check
the coolant level to ensure it is 1/2" from the top.
Add Cooling Solution as needed.
