2.6Connection of water pipes

During installation the actual pressure and pressure losses must be taken into account regarding pipe dimensions to assure sufficient pressure and water flow rates.

The plumbing must be carried out according to regulations.

The piping can be made of flexible or solid materials. Care must be taken in re- spect to corrosion to avoid damages.

As for all pressurerized containers the heat pump must also be equipped with safety and check valves on the supply side.

Cold water inlet and hot water outlet is located under the tank (3/4” thread con- nectors).

The maximum working pressure is 10 bars, and the maximum working tempera- ture is 65°C.

If necessary, the supply pipe must be equipped with a pressure reduction valve and eventually a filter.

When installing the pipe work in the house any dirt in the pipes must be avoided. (Eventually flush the pipes with clean water before the heat pump is installed)! When the pipes are connected make sure the pipes are not twisted. Use tools to hold the pipes against twisting!

If no recirculation is needed make sure the recirculation connector is closed!

Water connection

Under the heat pump the connections are located:

Condense water drain hose

Cold water inlet / Recirculation / Hot water outlet

No holes may be drilled. This can damage the winded condenser.
