Solution
Check power supply
Check fuse and change it if necessary
Wait until cooled off and care for enough ven-
tilation
Wait for 20 minutes maximum
Make sure that air can circulate free and that
ventilation louvers are not obstructed
Check application parameters, install
pre-separator
Check fan, replace if necessary
Send cooler for inspection
Drain flask
Flush both directions
Check limiting parameters
Check / flush heat exchanger
Send cooler for inspection
Temperature sensor defect. Send cooler for
repair
