Varian Turbo-V 2000 HT Instruction Manual page 34

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.
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 +20°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 following figure (dimensions are in
inches [mm]).
