3.3.2 Water connection
(only on version with rinse fitting)
Connect the water supply to the rinse fittings with internal thread provided (see Fig. 3.8).
One connection is for the water inlet, the other is the water outlet. Make sure that the
discharge is free and pressureless.
The CPA 471 assembly is operated at a water pressure of 2 to 6 bar. A dirt trap and a
non-return valve should be installed in the water supply line.
!
Note!
•
If the water pressure can rise above 6 bar (including any transient pressure surges),
install a pressure reducing valve upstream, otherwise the assembly may be
damaged.
•
The outlet should be located above the inlet as far as possible so that the electrode
does not run dry in the rinse chamber.
Besides water, other or additional cleaning solutions may be used in the rinse chamber.
However, pay attention to the material resistance of the assembly and comply with the
maximum permitted temperatures (see Technical Data).
3.3.3 Compressed air connection to assembly control
(only when equipped accordingly)
Fig. 3.13: Compressed air connections for CPA 471
•
Connect the compressed air supply line for »Measurement« to the upper ¼" screw
union.
•
Connect the compressed air supply line for »Maintenance« to the lower ¼" screw
union.
The CPA 471 assembly is operated at an air pressure of 4 to 8 bar.
The air must be filtered (40 µm), and be water- and oil-free.
There is no continuous air consumption.
!
Note!
If the air pressure can rise above 8 bar (including any transient pressure surges), install
a pressure reducing valve upstream, otherwise the assembly may be damaged.
