1.1 Introduction
Before using this device, all persons authorized to operate,
repair or inspect the unit must read the following safety and
operating instructions :
Remember: YOUR SAFETY DEPENDS ON YOU !
The operator is responsible for his own safety, and for that of
other persons in the working area. He must therefore be aware
of, and respect, all safety regulations.
NOTHING CAN REPLACE COMMON SENSE!

2.3 Description of protections
2.3.1. "Coolant pressure" protection
This protection is achieved by means of a pressure switch,
inserted in the fluid delivery circuit, which controls a
microswitch. Low pressure is indicated from the flashing
message H2O on the display E1.
2.4 Description of the apparatus
A3) Tank cap
B3-D3) Rapid joints for the torch cooling hoses.
C3) Slot for checking the coolant level.
E3) Controls connection cable.
F3) Power cable.
G3+H3) Rapid joints fo the cooling hoses of the joining
extension.
INSTRUCTION MANUAL FOR COOLING UNIT
3 INSTALLATION
3.1 Setting up
Insert the cooling hoses in the fittings of the cooling unit, being
careful to correctly place the delivery and the return ones.
Connect the power cord F3 and the controls cable E3 to the
respective sockets of the welding equipment.
Take care not to obstruct the flow of air through the cooling
slots.
3.2 Installation
The unit must be installed by qualified personnel. All
connections effected must comply with the current standards
and with the law on safety at work.
Unscrew the cap A3 and fill the tank. It is important to
periodically check through the slot C3 that the fluid remains at
the "max" level".
The cooling unit is supplied without coolant.
The coolant should be of the type used for cooling circuits in
the automobile sector. This is obtained by mixing water
(preferably deionized) with a glycol-based antifreeze, in
quantities which depend on the ambient conditions.
To facilitate this operation, follow these indications:
20% antifreeze when the ambient temperature is -9°C,
30% antifreeze when the ambient temperature is -17°C,
40% antifreeze when the ambient temperature is -25°C,
Important: This mixture not only maintains the fluidity of the
coolant at extremely low temperatures, but also prevents the
formation of chalky deposits from hard water which would
compromise the life of the system, in particular of the pump.
For this reason, you are advised to use antifreeze even during
the summer.
Warning! Prolonged dry operation of the pump may
compromise its functionality and life.
