COOLING UNIT UPKEEP
The following paragraphs describe the monthly
general maintenance procedures for the Cooling
Unit. These tasks include mixing/adding coolant
solution, cleaning the air filter, and cleaning the
coolant filter. Note that the frequency of these
procedures should be adjusted appropriately
during times of heavy use or while operation
under severe environmental conditions.
Mixing & Adding Coolant Solution
After prolonged use (due to evaporation or
spillage), or after performing maintenance on the
Cooling Unit, add coolant solution to the reservoir.
The following procedures describe the methods
used to properly formulate and add coolant
solution to the Cooling Unit.
1. A plastic container is needed to mix and store
the coolant solution. The container should be
appropriately sized to accommodate easy
handling, have a means of pouring the solution,
and a means of capping it off for storage.
2. In this container mix 14 parts of methyl alcohol,
with 7 parts distilled water, and 1 part soluble oil
(Chevron Soluble D or MOBIL S-122 Soluble).
Gently agitate the container to help blend the
solution.
3. Remove the top cover from the Cooling Unit,
then remove the radiator cap. Check that the
coolant level is within specifications. If the coolant
level is more than 1/2" from the top of the
reservoir, add coolant solution to the reservoir
until the level is approximately 1/2" from the top,
then replace the radiator cap.
4. Install the twin hose assembly between the
Cooling Unit and the Tube Head. Connect the
power cable between the Control Unit and the
Tube Head, and the power cord between the
Control Unit and the Cooling Unit. Turn the Key to
ON position and allow the coolant to circulate
through the system for approximately three
minutes.
5. Turn the system OFF and remove the radiator
cap. Inspect the coolant level and ensure it
remained within 1/2" from the top of the reservoir.
Add more coolant solution if necessary, and
repeat step 4.
! CAUTION !
Store the coolant container in a cool, dry
area with the cap on. Clearly mark the
container so that the contents are easily
identifiable.
Cleaning - Cooling Unit Air Filter
Clean the wire mesh air filter within the Cooling
Unit each month to remove dust, dirt, or debris
collected during use. Large accumulations of dirt
can impede the flow of air through the radiator
assembly, resulting in restricted or limited
cooling of the anode. The following procedures
describe the steps to remove and clean the
Cooling
Unit’s air filter.
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. Remove the four screws (with nuts) securing
the grille and filter to the inner side of the
protective case.
3. Remove dirt, dust, or debris from the filter by
washing it in a solution of mild detergent and
warm water. When complete, rinse the filter
thoroughly with clean, warm water. DO NOT use
gasoline or other solvents to clean the filter. Allow
the filter to dry completely, or blow off any
remaining moisture with compressed air.
4. Re-install the filter and grille assembly to the
protective case. DO NOT over tighten the
mounting hardware or distortion to the filter frame
may occur.
5. Insert the Cooling Unit chassis into the
protective
case. Make sure the filter assembly is positioned
directly in front of the radiator before tightening
mounting hardware.
