TROUBLESHOOTING FOR PRO COOLING UNIT
GENERAL MAINTENANCE OF PROCOOL 10
The amount of use and the working enviroment should be taken into consideration when
planning the frequency of maintenance. Careful use and preventive maintenance will
help to ensure trouble-free operation.
CHECK DAILY!
-amount of cooling liquid (NOTE! If cooling liquid has boiled, it must be
replaced, because then the solution has lost its metal coats protective effect.)
- check with test switch that liquid is also returned to reservoir.
-gaskets of welding/liquid cables. DON´T USE LEAKING WELDING CABLES OR
HOSES.
- condition of connection cables.
The number of systems in operation and the importance of minimize not running time
will determine to what extend consumable- and spare parts will be stocked.
