Installation

3.1

Water connection

During installation, regard must be paid to the dimensions of the pipes with re- spect to the pre-existing water pressure and the pressure loss in order to ensure sufficient pressure and water flow rates at the draw-off point.

The maximum working pressure is 10 bars, and the maximum operating tem- perature is 65°C. If necessary, the supply pipe must be equipped with a pressure reduction valve and possibly a filter.

As for all pressure vessels, the heat pumps connections must also be equipped with an approved safety valve on the service side and an approved check valve on the supply side.

All pipe work must comply with water safety regulations

3.2Placement of pipe connections

Hot water outlet is mounted on the upper connecting branch. (¾” RG)

If the unit is used with the circulation of the hot water supply, the middle connect- ing branch is used as a return path. (¾” RG)

Inlet of fresh cold water is mounted on the bottom connecting branch. (¾” RG)

It is recommended to use ¾” flex tube for the connection of the water connection, to avoid possible sound from the vibration.

No holes for fittings or the like may be drilled in the product! Such would be able to damage the functionality of the product and cause the product to have to be scrapped!

3.3Connection of condensation drain

While the heat pump is running, some condensation water will occur, which is conducted to the drain connecting branch (1).

The quantity of condensation water depends upon the humid- ity of the air going through the inlet to the heat pump.

The condensation connecting branch must be equipped with a hose with a tight air trap, and run to a drain. The air trap must contain a water column of at least 60 mm.

It is also possible to use other tight air traps, like a tube with one turn.

If mounting of the air trap is omitted, water damage or damage to the heat pump can arise! If the air trap is not correctly mounted, the warranty will not apply!
