3.1 Extra equipment, accessory
If the cooling unit is installed higher than the plasma torch, a non-return valve must
be installed, see accessories on page 20. Connect the non-return valve to the
“COOLANT SUPPLY TO TORCH” outlet on the reverse of the cooling unit. The
non-return valve closes if the supply pressure drops below 1719 KPa (250 psi),
which ensures that the coolant does not run out of the cooling unit when replacing
consumables.

4 INSTALLATION
The installation must be executed by a professional.
WARNING!
ELECTRIC SHOCKS CAN KILL
Always switch off and lock the machine according to the instructions before
making the electrical connections. If conductors are equipped with mains circuit
breakers, the breaker must be set to off and locked with a padlock to prevent
switching on unintentionally. If the included conductors come from a fuse box, the
affected fuses must be removed and the fuse box cover locked with a padlock. If it
is not possible to use a padlock, the mains circuit breaker or fuse box must have a
red notice displayed indicating that the circuit is being worked on.
CAUTION!
Do not run the pump motor intermittently, it causes unnecessary pump wear.

4.5 Pressure setting
The pressure is controlled by a relief valve next to the pump in the tank. Turn the
pressure setting screw clockwise to increase the pressure and anticlockwise to
reduce the pressure. The pressure is default set to around 1203 KPa (175 psi) at 5.7
l/min. This setting is suitable for plasma torch PT-36 in M3 systems. The setting does
not usually need to be changed if the cooling unit is to be used in any other
application.
Fig. 7. Pressure setting screw
The relief valve allows the coolant to pass through the radiators and back to the
tank.
The pump also has an integrated safety valve, which is default set to be fully open at
1719 KPa (250 psi). It is designed to protect the pump if the external relief valve
jams in the closed position. The relief valve must not be adjusted by the user. If the
external relief valve jams in the closed position and the outlet line is closed, the
pump motor is stopped by a thermostat if the pump temperature exceeds 55 °C.
5 OPERATION
General safety regulations for the handling of the equipment can be found on
page 4. Read through before you start using the equipment!
WARNING!
ELECTRIC SHOCKS CAN KILL
Do not rely on the indicator lamp, disconnect the cooling unit from the power
supply and disconnect the cable at the connection before opening the cover or
carrying out any work on the cooling unit.

5.1 Control device and indicators
A. Pump manometer
Indicates the pressure at outgoing
connection. The pressure is default set to
around 1169 - 1203 KPa (170-175 psi) at
5.7 l/min. Lower flow gives greater read off
pressure, greater flow gives lower read off
pressure.
Adjust the pressure using a pressure
regulator near to the coolant tank. The
pressure does not usually need adjusting
by the user, if the pressure regulator is not
replaced or the cooling unit is used for an
application that requires a lower pressure.
The pump is protected by a default set
safety valve. The setting for this valve must
not be changed.
B. Indicator lamp for mains voltage ON
Indicates that incoming power supply is on.
C. Indicator lamp for pump ON
Indicates that the pump and fan motor are powered.
D. Switch Auto/Test
In Auto mode, the pump and fan motors are
powered via the power source's control unit.
In test mode, the pump and fan motors are
powered directly.
E. Indicator lamp for overheating
If the coolant flow through the cooling unit is blocked and the pressure regulator
does not work properly, the pump is protected by the integrated safety valve. After a
few minutes operation under these conditions, however, the pump reaches
temperatures so high that it can become damaged. Too high temperature trips the
pump's thermal cutout.
F. Fuse F1 and F2
Fuses for 230 VAC supply for cooling unit to the fan respectively pump motors.
