Filling the reservoir and water lines
WARNING
Avoid contact with coolant. Wear waterproof
gloves and protective eye wear.
The cooler should be filled and used only in the vertical
position.
Use only recommended coolant FREEZCOOL -
W000010167
Do not use pre-packaged welding industry coolants.
These coolants may contain oil-based substances,
which attack the plastic components of the cooler. Once
added to the cooler, these substances are impossible to
purge from the water lines and heat exchanger.
Do not use automotive anti-freeze. These coolants will
damage the pump and block of the heat exchanger,
affecting cooling performance.
WARNING
Never operate the cooler with the reservoir empty.
WARNING
Do not start the cooler with less than 3 liters of coolant.
Operating without enough coolant can prevent full priming
of the system and may damage the pump.

Assemble the welding setup (see Installation on
Power Source chapter)

Turn the power source on. If COOL ARC
®
26 is
connected properly, power source will recognize it.

When the COOL ARC
®
26 was connected for a first
time welding source automatically starts the filling
procedure (Figure 15 or 24). Remove the reservoir
cap to prevent generating a partial vacuum.

Fill the coolant reservoir to the maximum level - 4
liters - (Figure 16 or 25).

Connect the short black hose with quick water
connectors (BYPASS included with the equipment) to
blue outlet socket on front of the power source.
Observe the coolant circuit, wait till the coolant starts
leak from the BYPASS. For a coolant overflow
recommended is to use FREEZCOOL reservoir -
(Figure 17 or 26).

When coolant will start leaking from BYPASS,
connect second quick connector of BYPASS to red
inlet socket on front of the power source - (Figure 18
or 27).

Wait until the coolant fully circulates through the
cooling system and returns into the reservoir -
(Figure 19 or 28).

Disconnect the BYPASS.

Connect the torch hoses and interconnection cable
when using power source with separate wire feeder
– (Figure 20 or 29).

Wait until the coolant fully circulates through the
cooling system - (Figure 21 or 30).

Check the coolant level and add if required fill in
coolant to reach level between minimum and
maximum, which is present on front label
COOL ARC ® 26 - (Figure 22 or 31).

Tighten the cap.

If the filling process is successful (Figure 23 or 32),
the cooler switches to AUTO mode.
