4.5.4 Installation of the P connection kit

The optional P connection kit for Biv device types allows better ac-

solar system or another external heat generator on the storage tank.

The kit contains two thermally insulated corrugated pipes that are

connected to the connections of the storage tank via a union nut. At

the other end of the corrugated pipes there is an adapter for different

connection sizes of the inflow and return flow lines.

Important information

CAUTION

If the indoor unit is connected to a heating system with

steel pipes, radiators or non-diffusion-proof floor heating

pipes, sludge and chips can enter the hot water storage

tank and cause blockages, local overheating or corro-

sion damage.

▪ Rinse supply lines before filling the device.

▪ Rinse out the heat distribution network (in the existing

heating system).

▪ Install a dirt filter or sludge separator in the heating re-

turn flow (see chap.).
