CAUTION!
Only operate the cooling unit after it has been filled with coolant.
If water-cooled system components are put into operation without coolant, this usu-
ally results in a defect of the system components.
The manufacturer is not liable for any resulting damage, and all warranty claims are
voided
CAUTION!
Use only original coolant from the manufacturer (Cooling Liquid FCL 10/20 or ethan-
ol-based coolant) when filling the cooling unit.
Other coolants are not recommended for electrical conductivity and material compat-
ibility reasons.
Ensure that all hosepacks and welding torches are undamaged
Check that there is an all-round clearance of 0.5 m (1 ft. 7.69 in.) to ensure that cool-
ing air can flow in and out freely
Check the screw connections between all system components of the welding system
for tightness
Check all the coolant connections of the welding system for tightness
Monitor the coolant return flow in the coolant tank
- If no coolant is returning to the container, identify and remedy the cause
Check coolant level. If the coolant level is below the "min" mark, top up with coolant.
