Assembly

4.1 Installation Guidelines
• Safety valve must be installed in the cold water supply
pipework before the water heater
• The installation must be carried out so that:
– There are no shut-off valves or fittings, narrowing
of the pipework or strainers between the water
heater and the safety valve
– Good access is provided for service and
maintenance
– The draining water must be visible and mustn't
damage persons or electrical devices
– The safety valve is fitted above the top of the water
heater to avoid the need for draining down when
exchanging the safety valve insert
– That between the safety valve and heat exchanger
a max. 1 m long straight connection line with the
size of the inlet diameter is installed
• The discharge line must be performed to the size of
the safety valve outlet diameter and may not have
more than 2 elbows and or be longer than 2 m
• The discharge line must be installed with an incline
• If there is no drainage facility in the room where the
heater is installed, then the safety valve may be fitted
in an adjacent area. DIN 1988-200 is to be observed
• The installation location should be protected against
frost
• The safety valve must be mounted so that in its
installed condition no external forces act on it
• Nearby the safety valve must be signed
– Drainage water can discharge
– Not locking!
• Requires regular maintenance in accordance with
EN 806-5
4.2 Assembly instructions
CAUTION!
The safety valve may not be overheated through
welding and soldering work on the system. Install
the safety valve only after these tasks are
completed.
1. Thoroughly flush pipework
2. Install the membrane safety valve
• Tighten the connections with max. 18 Nm when
joining. Cracks may form in the material when
tighten to strongly which may cause leaks in the
system.
• Installation in horizontal pipe with safety cap
