9.7 Leak test
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instruction for work on live com-
ponents.
Leakages may invoke leak currents.
The leak test described below must be done
after all maintenance work that affects the
water circuit inside the unit. If work has been
done at several points, the final leak test is
enough, although this work step is listed for
all parts of the work.
The leak test must be done with the unit
open, paying particular attention to the warn-
ing above.
» Open the water supply.
» Switch on the unit and check the
inside for leaks (hose connections,
O-rings, seals) after 15-30 minutes
of operation.
» In case of leakage turn off power
supply and secure against being
switched on again.
» Find leakage and eliminate.
» Check again.
» Follow the instructions in the sec-
tion
funktional check .
9.8 Functional check
» Run the system with maximum out-
put for a couple of minutes
» Check hose connections and seals
for leakage.
