COOL ARC
®
47
Priming Pump (only for first time use)
and Bleeding the Cooling System
Figure 6.
•
Assemble the welding setup.
•
Connect the short
hose with quick water connectors
(included with the equipment) to the cooler’s inlet
and outlet sockets (Figure 6).
•
Fill the coolant reservoir – minimum 1,06 gal
(4 liters).
•
Remove the reservoir cap.
WARNING
During the first use of the
COOL ARC
®
47, the
reservoir
cap must be removed to avoid generating a partial
vacuum in the cooling system while priming the pump.
•
Turn the power source on.
•
Wait 30 seconds until the coolant fully circulates
through the cooling system and returns into the
reservoir.
•
Turn the power source off.
•
Disconnect the short hose with quick water
connectors.
•
Connect the torch water-cooler hoses – Figure 7.
•
Turn the power source on.
•
Wait 30 seconds until the coolant fully circulates the
cooling system and returns into the reservoir.
•
Tighten the cap.
WARNING
After priming the pump and/or bleeding the cooling
system, be sure the reservoir’s cap is tightened.
Operating the cooler without the cap tightened, can
cause poor cooling efficiency, evaporation loss of
coolant, and low product life.
•
The welding set is ready to work.
Connecting the Cooling System Hoses
•
The power source has to be turned off.
•
Connect the "inlet" hose of torch/gun
(colored or tagged blue on most hoses) into
the outlet quick connect coupling [4] located
on the front panel of the cooler.
•
Connect the "outlet" hose of torch/gun
(colored or tagged red on most hoses) into
the inlet quick connect coupling [5] located
on the front panel of the cooler.
Figure 7.
Warning:
The water-cooler hoses are connected into
the quick connect coupling type 21KATS09MPX (see
"Spare parts" section), which automatically close when
hoses are disconnected.
Before installing the hoses to the cooler, you should
check if the hose connectors match the quick connect
couplings located on the front panel of the cooler.
WARNING
Avoid kinking or putting sharp bends in any water lines.
WARNING
Keep all water lines clean and free of any blockage.
WARNING
Keep the reservoir full especially after changing any
water lines.
Transport
To avoid freeze damage and water leakage during
transport, the coolant must be removed from the cooler’s
reservoir.
