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,
etc.) and cut-off 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.
