Hydraulic Installation; Cold Water Connection - Weider BWP 270 0A Mode D'emploi Et D'installation

HYDRAULIC INSTALLATION

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.

COLD WATER CONNECTION:

The DHW HP core is a pressure tank intended for multiple outlets. The hydraulic connections 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 shut-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 resect 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 generation of DHW.
NOTE: The heat pump should only be launched when you are e 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 8 to 10 hours. Choose the HP operating mode to start, perhaps in combination with
the supplementary heating.
INSULATION OF THE INSTALLATION:
All pipes and fittings and connectors on the DHW side must be insulated to prevent heat loss. Unused connectors have
to be sealed and insulated.
NOTE: The proper insulation measures are mandatory for an efficient operation of the DHW HP. The non-respect of these
rules might be the origin of customer complaints.
