Instructions, standards and regulations
Note
Observe all applicable national and regional regula
-
tions and instructions.
◦
The protection rating IP 25 (hoseproof) can only be
ensured with a correctly fitted cable grommet.
◦ The specific electrical resistance of the water must
not fall below that stated on the type plate. In a linked
water network, observe the lowest electrical water
resistance (see chapter «Specification / Application
areas / Conversion table»). Your water supply utility
will advise you of the specific electrical water resist
-
ance or conductivity.

table», On). Increase the mains water pressure if the
required flow rate is not achieved with the draw-off
valve fully opened.
