The heat pump should only be launched when
you are sure that the tank is completely filled with
water.
At first launch (or when the tank has been drained)
the heat-up time (ambient air temperature of
approx. 15°C, DHW temperature 45-55°C) is likely
to be 4 to 6 hours. Choose the HP operating mode
to start, perhaps in combination with the
supplementary heating.
The installation must be done according to the
state of the art of installation. The non-respect of
these rules and abnormal water composition may
be the reason of warranty exclusion. The
manufacturer has no liability for the installation
and possible damages to it.
Your DHW HP has a high quality stainless steel tank for the
DHW production. In order to protect the tank and also the
connectors you have to avoid connecting copper pipes or
galvanized steel fittings directly. The use of insulation fittings is
mandatory in this case.
COLD WATER CONNECTION
The DHW HP core is a pressure tank. The hydraulic connec-
tions have to be made in accordance with the local, national
and international regulations and standards. Generally the
water inlet is protected by a safety device (safety valve and
drain combined) as well as a backflow protection (retention
valve) and a shunt-valve. These fittings are not included in the
delivery. The use of approved new fittings is mandatory. If the
supply pressure is > 5 bar.
DHW CONNECTION
Please respect the legal an specially hygienic requirements for
DHW and the restrictions given by the use of different
installation material. The DHW HP might be used as unique or
additional source for the production of DHW.
INSULATION OF THE INSTALLATION
All pipes, fittings and connectors on the DHW side must be
insulated to prevent heat loss. Unused connectors have to be
sealed and insulated.
The installation and the first launch of the DHW HP have to be
made by a qualified and authorised installer according to the
instructions and recommendations of this manual. The respect
of the manufacturer’s instructions, as well as the respect of the
actual local, national and international standards, regulations
and laws as well as the state-of-the-art regarding water and
electrical installations is mandatory and part of the warranty
requirements
