Danger!
n
Health hazard through cleaning
detergents.
Due to the possible adding of
detergents to the system water, the
water exiting from the system must not
be used as drinking water.
Switching the System ON
Open the water tap for water
supply and cooling water.
Turn the Emergency-STOP
master switch (Q1) to the I (ON)
position.
Press the unlock button (S1).
n Carry out the cleaning procedure. The
pump stops for a cleaning break of
more than 15 seconds. At the same
time the 6 hours of continuous
availability time is started.
Within the availability time the system
starts automatically owing to the drop
in pressure when opening a handgun.
Restoring Operational Readiness
Press the unlock button (S1).
4. Stopping the System
Turn the system’s Emergency-
STOP master switch to the 0
(OFF) position.
Shut OFF the water supply.
Open the handgun until the water
pressure has dissipated.
Using the locking feature, secure the
handgun against being opened
accidentally.
5. Frost Protection
The water-bearing parts of the system must
be protected from freezing, since they
could otherwise be destroyed. If the system
is to be operated also in freezing
temperatures, it must be installed in a frost-
free location. Outdoor water lines must be
frost-protected (i.e., through insulation or
line heaters, or by draining during freezing
temperatures).
6. System Shut-Down
If a system is to be shut down during cold
periods, it must first be flushed with an
antifreeze solution. As a rule, antifreeze
products also contain corrosion inhibitors.
