Kermi Anti-freeze Valve Set 1 1/4" for x-change dynamic pro S/M/L

Kermi Anti-freeze Valve Set 1 1/4" for
x-change dynamic pro S/M/L
consisting of 2 thermostatic
safety valves incl.
connection accessories for installation in the flow
and return of the heat pump outdoors.
If the temperature falls below 3°C, the
valves open mechanically and the
heating circuit water drains out
(closing temperature +4°C).
It is recommended to install the
anti-freeze valve set if,
for example, in winter there is a risk of frost and a
power outage could go unnoticed or
last for an extended period.
Installation is carried out in the horizontal
section of the pipe directly after the
heat pump below the condenser
and the openings of the
anti-freeze valves must not be insulated or closed
at the top and bottom.
