2. INSTALLATION
2.1 Connecting the cooling system
Fill the coolant container through the filling tube. When the maximal level is reached, the
built-in mechanical float switch breaks the water delivery. At the same time, circulation pump
starts to operate for a while to allow automatic ventilation of the system.
NOTE! The transfer pump must be switched on only when the system is completely filled. Running
dry can damage the pump.
If the cooled welding torches are located higher than the radiator, the coolant starts to flow
back when you switch off the pump, and the coolant container may overflow. In this case you
can set a check valve (either magnetic or manual) in the flow circuit.
2.2 Electrical connection
All local electrical and electronic regulations must be complied with when making the
electrical connections. Before taking the equipment into use, check that the environment
fulfils the following requirements.
Mains voltage 230 V, 50 Hz
Max. fuse protection 10 A
Wire cross section 1.5 mm2
3. TAKING THE MACHINE INTO USE
When you have filled the cooling system and made the necessary electrical connections, you
can turn on the heat exchanger group. The pump starts when you switch the device on.
If the desired pressure is not reached, please do as follows:
1. Check the coolant level in the cooling system and fill if necessary.
2. Check all joints.
3. Ventilate the system one more time.
3.1 Service and maintenance
The heat exchanger does not require any special servicing. However, it is recommended to
check regularly the hoses and connections for leaks.
NOTE! Always ensure that the voltage is switched off when carrying out any kind of maintenance
or service work on the KempCool 40 cooling device.
NOTE! Do not change electronic connections or make any technical modifications on the machine.
For repair work, contact authorised Kemppi service workshop.
