INSTALLATION, SAFETY AND OPERATIONS
WARNING! ALL THE INSTALLATION OPERATIONS AND
ELECTRIC CONNECTIONS SHOULD BE CARRIED OUT WITH
THE EQUIPMENT TURNED OFF AND DISCONNECTED FROM
THE POWER SUPPLY. EXPERT AND QUALIFIED PERSONNEL MUST
CARRY OUT THE ELECTRIC CONNECTIONS.
LIFTING THE EQUIPMENT
The cooling unit described in this manual is not fitted with lifting systems.
POSITIONING THE EQUIPMENT
The installation position for the cooling unit must be chosen to ensure
that the cooling air inlet and outlets are not blocked in any way (forced
fan circulation, if fitted); at the same time, ensure that no conductive dust,
corrosive vapours, humidity, etc. could be sucked in.
A free space of at least 250 mm should be left around the cooling unit.
WARNING! Position the equipment on a flat surface
adequate to support the weight, to avoid it tipping over or
making dangerous movements.
CONNECTIONS TO THE POWER SUPPLY
- Before carrying out the electric connections, check that the data on
the specification plate on the cooling unit corresponds to the power
voltage and frequency supplied in the installation area.
- The cooling unit must be connected to a power supply with the neutral
lead grounded.
PLUG AND SOCKET: connect a normalised plug (2P + T) to the supply
cable and prepare a socket with corresponding features: the ground
terminal must be connected to the ground lead (yellow-green) in the
supply line.
The plug and socket must have a rated voltage and current that
corresponds to the technical specifications.
In case the supply is carried out through a socket or a terminal board,
provided for this purpose, on the welding machine, follow the instructions
for the connection given on its panel.
OPERATION
WARNING!
THE TANK FILLING OPERATIONS SHOULD ALWAYS BE
PERFORMED WITH THE MACHINE SWITCHED OFF AND
DISCONNECTED FROM THE MAINS SUPPLY.
ONLY USE THE COOLANT RECOMMENDED BY THE MANUFACTURER
OF THE COOLING UNIT.
NEVER USE POLYPROPYLENE BASED ANTIFREEZE LIQUIDS.
1- Use the nozzle to fill up the tank: Tank CAPACITY = 5 l; do not overfill

it to prevent any liquid overflowing.
2- Close the tank cap.
3- Connect the torch terminals as follows and check they are correctly
inserted, since the unit does not signal no or improper connection:
: LIQUID DELIVERY (cold)
-
= blue flexible hose corresponding to the GRA socket
indicated by the relevant symbol.
: LIQUID RETURN (hot)
-
= red flexible hose corresponding to the GRA coupling
indicated by the relevant symbol.
4- Connect to the socket and close the switch (position I).
The cooling unit starts to work making the liquid in the torch
circulate.
5- After running for a few minutes, especially if connection extension
hoses are being used, it is necessary to top-up the tank level with a
suitable amount of liquid.
6- Periodically check the level of liquid in the tank.
7- If there is a lack of liquid return flow in the tank, switch the
cooling unit off immediately and refer, for first intervention, to the
maintenance section.
8- Do not operate the unit if the torch tubing is not connected,
otherwise liquid will freely leak which would cause damage to the
electrical circuits nearby.
MAINTENANCE
WARNING! BEFORE CARRYING OUT MAINTENANCE WORK,
MAKE SURE THE COOLING UNIT IS SWITCHED OFF AND
DISCONNECTED FROM THE POWER SUPPLY.
ROUTINE MAINTENANCE:
ROUTINE MAINTENANCE WORK CAN BE PERFORMED BY THE
OPERATOR.
- Check the level of liquid in the tank on a regular basis, according to the
degree of use.
- Check on a regular basis that the external flexible hoses connected to
the cooling unit are not obstructed.
- Change the coolant every 6 months.
EXTRAORDINARY MAINTENANCE:
EXTRAORDINARY MAINTENANCE
CARRIED OUT ONLY AND EXCLUSIVELY BY SKILLED OR AUTHORISED
ELECTRICAL-MECHANICAL TECHNICIANS.
WARNING! BEFORE REMOVING THE COOLING UNIT PANELS
AND GOING INSIDE, MAKE SURE THE EQUIPMENT IS
SWITCHED OFF AND DISCONNECTED FROM THE MAIN
POWER SUPPLY.
If checks are carried out while the inside of the cooling unit is live,
this could cause a serious electric shock due to direct contact with
live parts and/or injury due to direct contact with moving parts.
In the following cases:
- excessive need to restore the level in the tank,
- liquid leaks,
switch off the cooling unit immediately, remove the plug from the power
socket and examine the tubing, the coupling elements and the internal
and external components on the cooling circuit and make any repairs as
necessary.
