Installation
Connect the water pipes to the coupling connections (delivered with the pump):
Water inlet = female connection,
Water outlet = male connection.
Connect the plugs on
WATER IN
and
WATER OUT
Check that there are no leaks in the pipes and connections of the water circuit.

Connection to the nitrogen circuit
A filtered dry nitrogen supply with the characteristics defined is required
for opti-
mum performance

Procedure
WARNING
Pressurised circuit
In order to carry out operations on the product safely, the user must:
Fit a manual valve on the water circuit 3 m from the product allowing the cooling cir-
cuit to be locked.
WATER IN
WATER OUT
DANGER
Risk of explosion
If pyrophoric materials above the LEL (lower explosive limit) are sent to the pump, the
nitrogen supply must make it possible to dilute this concentration.
Ensure there is a sufficient flow of nitrogen to lower the concentration below the LEL.
Provide in addition an interlock to ensure that gas flow towards the pump is stopped
when nitrogen is lost.
NOTICE
Risk of damage of internal parts
A sudden inrush of nitrogen into the pressurization circuit may result in damage to inter-
nal parts.
Close the pressure regulator
R1
by turning the knob counterclockwise before pres-
surizing the circuit.
NOTICE
Risk of nitrogen supply failure
If loss of purge flow creates a significant risk for the process:
Control the nitrogen supply using an external system able to take over in case of fail-
ure.
