from the safety valve can occur, which indicates that the
pressure has increased above the rated value, which
triggered the valve. This may in no way be prevented.
■ Safety valve drain line should be installed with a decline, in
an environment free of freezing and remain open to the
atmosphere. The manufacturer is not responsible for
flooding the room through the safety valve.
■ Blocked safety valve can cause equipment failure. Drain
the outflow from the safety valve to the sewerage or drain
grate.

8. Hot water expansion vessel
Information
In order to minimize the flow of water from the safety valve
associated with the thermal expansion of the liquid, it is
advisable to install a suitable expansion vessel at the cold
water connection (see item 8.)
CAUTION
Installation of the appropriate safety valve in the cold
water supply line protecting the unit against
overpressure is mandatory!
CAUTION
Installation of necking of any kind (such as reducers, dirt pockets,
valves between the storage tank and the safety
valve is not allowed. Only a T-pipe with a drain valve and a T-pipe
with an expansion vessel may be installed in these line sections.
CAUTION
Never block the safety valve or drain line. This can cause
a dangerous overpressure in the storage tank.
CAUTION
When heating water, slight, temporary discharge from
the safety valve can occur. This is a correct safety valve
function. Any attempt to interfere in its operati on can
lead to the danger and destruction of the storage tank.
CAUTION
Never use the equipment with clogged safety valves.
Connection
After the installation and levelling the tank, follow the proce-
dure below (for the connector pipe symbols, refer to page 82):
1. Remove protecting plugs from the connector pipes
2. Connect the hot water intake line (N).

medium to the coil.

reducer if the pressure at the cold water inlet to the tank is
higher than allowed.
Connect the water supply system according to the installation
diagram.
