Warning
Pressure limiter device
The pressure limiter device (safety valve or
safety unit) must be regularly operated in order
to remove limescale deposits and ensure that it
is not blocked.
A pressure limiter device must be fitted to a
discharge pipe.
As water may flow out of the discharge pipe, the
pipe must be kept open to the open air, in a
frost-free environment, and at a continuous
downward gradient.
To ascertain the type, specifications and
connection of the pressure limiter device, refer
to the chapter "Connecting the domestic hot
water tank to the drinking water mains" in the
domestic hot water tank Installation and Service
Manual.
