REMOVING THE COOLING UNIT
Removal of the cooling unit is carried out in the same way as described in chapter 3. INSTALLATION,
except that it’s carried out in the reverse order.
START-UP / DRAINAGE
This section explains the process which needs to be made before first usage or a longer period
of inactivity of the Cooling unit , also in the case in which the electro pump does not go under
pressure. This process called drainage is necessary to undertake in order to eliminate all the air
bubbles present within the hydraulic circuit.
WARNING
•
Read the precautions for coolants and follow them during the whole process of start-up.
Drainage:
1.
Pour the coolant into the tank so that the level of the coolant is between the MIN and MAX mark.
As coolant, mixtures shown below can be used.

2.
Using the Pipetting Bulb (606499), squeeze the bulb fully and hold in this condition.
3.
While the pipette bulb is squeezed, connect the connector on the end of the hose with the blue
connector on the front of the cooling unit.
4.
Release the pipette bulb and wait until the coolant (and maybe air bubbles) fully fill it the bulb as
well as the hose.
5.
Disconnect the pipette bulb and the hose from the Cooling Unit and empty the coolant into the tank.
6.
Repeat the process from point 2 to 5 until the air bubbles at point 4 no longer appear. Usually two
to three repetitions are required.
7.
Adequately (by color) connect the cooling unit to the wire feeder with water hose.
8.
Turn on the welding power source and press the Water / TORCH buttom on the operational panel
(see welding power source owner’s manual), to engage the cooling unit.
9.
After a minute re-check the coolant level, and add additional coolant if necessary.
Note: On long torches, such as a water-cooled push-pull torch, it may be necessary to restart the
power source multiple times to clear the E-501 error and allow the coolant to flow back to the cooler
and engage the flow switch.
10. The Cooling Unit is ready to use.
