Varian 969-9037 Série Mode D'emploi page 35

The metallic model is assembled as shown in the
figure.
Two 6 mm (1/4") internal diameter rubber or plastic
hoses from the water supply must be fitted to the
two nozzles.
These hoses must be held on the respective noz-
zles using hose clips to avoid that the tube(s) gets
loose or disconnected during operation.
The plastic model must be screwed into the suit-
able holes of the pump.
Cooling may be carried out either through an open
circuit with eventual discharge of the water, or us-
ing a closed circuit cooling system.
The water temperature must be between +10°C
and +30°C, with an inlet pressure between 3 and 5
bar. This allows a flow of about 200 l/h.
The water electrical conductance must be
µs/cm. When the conductance is higher, in closed
water circuit, the use of up to 20% of Ethyl-Glycole
is suggested.
The overall dimensions of the pump when
equipped with the water cooling kit mounted are
shown in the figure below.
