Connection to water supply
Please pay attention to the regulations of your waterworks company! In accordance
with DIN EN 61770, the machine may not be directly connected to the public drinking
water supply lines. A brief connection however is permissible according to DVGW
(German Association for Gas and Water Affairs) if a tube ventilator with check valve
(Kränzle Order-No. 41.016 4) is built into the water supply. Also indirect connection to
the public drinking water supply lines is permissible by way of free emission in
accordance with EN 61 770; e.g. by using a reservoir with a float valve. Direct
connection to a non-drinking water supply line is permissible.
Electrical connection
The voltage given on the specification plate must match the mains
voltage.
The machine is supplied with power cable without plug. The plug has to be
equipped with a safety earth terminal and a 30 mA residual-current circuit breaker.
The mains connection has to be fused with a time-delay fuse according to the
specifications on page 6/7.
If an extension cable is used, it must have an earth line that is properly connected to the
plug connections. The conductors in the extension cable must have the following
minimum cross section:
2
at 18 kW - 6 mm
2
at 24 kW - 10 mm
2
at 36 kW - 16 mm
2
at 48 kW - 25 mm
Extension cables that are too long cause a drop in voltage and thus
malfunctions. If you are using a cable drum, the cable must always
be fully unwound.
