Vent Accessories; Tv 301 Navigator Controller Compatible - Varian TV 301 Mode D'emploi

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.
NOTE
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 +30°C, with an inlet pressure between 3 and 5
bar. This allows a flow of about 200 l/h.
NOTE
The water electrical conductance must be
µ
s/cm. When the conductance is higher, in closed
water circuit, the use of up to 20% of Ethyl-Glycole
is suggested.
