2.4 Fittings
2.4.1 Cooling water fitting

The cooling water input and output has a
G1/4“-internal thread and a G3/8“-external thread.

The maximum cooling water pressure is 15 bar (271 psi).

While connecting the hoses keep inclined the Cooling Jacket at an angle of approx. 45° to
avoid air bubbles.
2.4.2 Air purge collar

Use oil-free, technically clean air only.

The needed amount of air (at least 120 l/ min., 5-8 bar) depends on the application and the
installation conditions on-site.

The air purge collar has a
G1/4“-internal thread and a G3/8“-external thread.
The lens must be kept clean at all times from dust, smoke, fumes and other contaminants in order to avoid
reading errors. These effects can be reduced by using an air purge collar.
