4 MainTenance
Check the coolant level and antifreeze regularly and refill if necessary.
4.1 heaT exchanger
In order to achieve maximum cooling capacity, the heat exchanger of the cooling unit must be kept clean.
Check the heat exchanger every three months for cleanliness. If cleaning is required, perform the following:
1. Disconnect the cooling unit from the main power source.
2. Remove the side cover.
3. Clean the heat exchanger with compressed air, a damp cloth or shop vacuum.
4. Mount the side cover.
4.2 pUMp
The pump has incorporated a coolant filtering mechanism to keep debris out of the pump. It is
recommended to check the filter every three months to make sure it is clean. If cleaning is required,
then perform the following:
Note:
If the filter is not cleaned, then degradation to pump may occur.
1. Disconnect the cooling unit from the main power source and external hoses.
2. Drain the coolant from the reservoir.
3. Remove the side cover.
4. Close the ball cock.
5. Unscrew the filter cap with a wrench that can accommodate a 24 mm nut.
Note:
Some coolant may run out from the pump. Collect in a suitable container.
6. Remove the filter and clean with mild soap and water or replace.
7. Insert the filter into the housing and tighten the nut.
8. Open the ball cock.
Note:
Do not operate the cooling unit when the ball cock is closed, as this can damage the pump.
9. Mount the side cover and reposition the cooling unit on its legs.
10. Refill the coolant in reservoir and run for 10 minutes to deaerate.
Check the coolant level and refill if necessary.
