DHP-iQ
The hot water tank must be equipped with an approved safety valve.
(DHP-iQ Maxi)
Heating systems with closed expansion tanks must also be supplied
with approved pressure gauges and safety valves.
Cold and hot water pipes and overflow pipes from safety valves must
be made of heat resistant and corrosion-resistant material, for exam-
ple copper. The safety valve overflow pipes must have an open con-
nection to the drain and visibly flow into this in a frost-free environ-
ment.
Do not start the unit ( DHP-iQ Maxi) if there is a possibility of frozen
water in the immersion heater.
When cooling, it is important to limit the lowest flow line temperature
to prevent condensation.
