External antifreezing circulation/emergency frost protection attachment set
Please read and comply with
these instructions prior to the
initial operation of your appliance. Retain
these operating instructions for future refer-
ence or for subsequent possessors.
Function
In plants with an external collective shaft,
the water is led into the circuit and flows in
the following path:
– Circulation pump for frost protection
with filter
– Filter with manometer and locking valve
– Heating coil in the warm water tank
(Only optionally available for SB MB)
– Distributor
– High pressure module
– Washing tool
– Backflow of frost protection water
– External collective shaft
Water losses are balanced out with soft wa-
ter via the swimmer valve.
DANGER
Health risk from contaminated drinking wa-
ter. The float valve must be isolated from
the drinking water network via an isolator to
compensate water loss. It is sufficient for a
water softening unit to be connected to the
drinking water network via an isolator when
in use.
WARNING
The inside room lighting and the sockets
(230V0 are functioning even when the main
switch is switched off. Electrically con-
trolled anti-freeze equipment remains de-
activated. The optional attachment set
'emergency anti-freeze' is activated when
the main switch is switched off. When the
anti-freeze valve is opened, fresh water
comes out to the spray guns via the high-
pressure pumps.
