1487 the specified pressure must not
exceed 7 bar. Other safety valves should
be calibrated to a pressure that is 1 bar
less than what is specified on the product
type plate. In such cases the supplied
safety valve cannot be used.
• The safety valve and the pipe between the
valve and the product must be protected
from freezing. When emptying with a
hose the free end of the hose should
always be open to the atmosphere (not
immersed in fluid). The hose must also be
protected from freezing.
• The product must only be installed in
areas where the floor has an approved
sealing layer and where it is possible to
empty the pipes, otherwise there is a risk
of material damage in the event of a fault
in the hot water system. Do not put non
water resistant material or items under
the product. If the product is installed in
an area without an approved sealing layer
a collector trough that runs to a drain
should be placed under the product.
• It is normal for water to drip from the
safety valve outlet during operation. The
safety valve should be open to the
atmosphere. Take steps to collect and lead
water away from any leakage, otherwise
there is a risk of water damage.
• The product must be emptied if there is a
risk of the ambient temperature falling
below 0°C.
The power supply to the product must be
disconnected before the product is
emptied of water.
Connection to water pipe
1. Inlet pipe.
2. Safety valve (8 bar).
3. Pressure relief valve (if the water pressure
exceeds 6 bar).
4. Shut-off valve.
5. Funnel shaped outlet to drain.
6. Hose.

Collector trough sold separately.
Colour marking
Note the colour markings (rings) on the pipes
when connecting to water pipe.
• BLUE for water inlet/cold water.
• RED for water outlet/hot water.
Shut-off valve
The shut-off valve with safety valve supplied
with the product must be installed. The shut-off
valve with safety valve must be installed in the
supply pipe as per the flow arrow on the valve.
Filling the product
The product is filled with water by opening
the tap in the supply pipe and the mixer’s
hot water tap. The product is filled with water
when the flow of water from the mixer tap is
continuous. The mixer tap can then be closed.
NOTE:
• It is not permitted to use any other type
of shut-off device between the shut-off
valve with safety valve and the.
• The use of other shut-off valves with
safety valve can cause the product to
malfunction. Any such devices must
therefore be removed.
• It is not permitted to install the shut-off
valve with safety valve on thread longer
than 10 mm, because this can damage
the valve and can result in the use of the
product causing a risk of personal injury
and/or material damage.
• The safety valve and the pipe between the
