7.5 Cooling of the machine – Cooling set K4
The cooling unit is factory-filled with approx. 2 l of coolant EFS 15. Top up the water
container with coolant via the fill opening on the rear of the device (
). As
soon as coolant extends into the neck of the filler pipe, the maximum filling level is reached.
To refill coolant, the welding machine has to be placed on a flat surface. To fill long
interconnecting and torch hoses, the water pump can be switched on by pressing the key
2) on the back side of the machine.
Please observe information on the cooling unit.
Please only use the original Jäckle & Ess coolant type EFS 15, item no. 450152.
Do not mix with other coolant!
We recommend to exchange the coolant completely in 12 to 14 months.
