3.6. Pipe installation
The hydraulic connection of the heat pump may only be carried out by a qualified specialist.
The horizontal sections of the connecting pipe shall
always be routed so that they can be air bled. The
connecting pipe shall be insulated. Pipes laid in
the exterior of the building shall be provided with
thermal insulation resistant to moisture with a
minimum thickness of 19 mm. Indoors the piping
shall be provided with insulation at least 13 mm
thick.
The connection dimensions of the heat pump pipes
are G 1“ F. Compensators shall be fitted to these
pipes to increase the frost protection of the heat
pump heat exchanger. Compensators are included
in supply. A G 1“ M nipple, which is included in
supply (incl. gaskets), is used to connect the heat
pump outlet pipe to the compensator.
To limit the transmission of vibrations to the house structure, it is recommended to connect the heat
pump using braided diffusion-tight hoses of suitable length. Hoses are included in the delivery only
for heat pumps supplied as a Special Offer, otherwise they must be ordered separately. Braided dif
-
fusion-tight hoses with F/F or M/F threads for RTC 6i heat pumps can be ordered in lengths of 500,
700 and 1000 mm. To eliminate the transmission of vibrations to the adjoining pipeline and possibly
also to the house structure, it is recommended to run the braided hose loose in a slight bend.
When installing compensators and braided hoses, follow the instructions in the separate Installation
Manuals that will come with these products.
Continue after the braided hose with copper, stainless steel or other pipes of suitable size. The
appropriate dimension of the pipe is prescribed by the heating designer, the dimension specified by
him is binding and must be observed during installation. Below are only indicative recommended
pipe dimensions:

For the correct operation of the device, it is necessary to keep the minimum flow through the heat
pump at the level of
min. 680 l/h.
In heating systems, use treated water that is properly filtered and free of all impurities. In
particular, it is important that the heating water does not contain more than 300 ppm of
chlorides and that the pH value is between 6 and 8.
Make sure that the filter with magnet is installed.
Avoid using zinc-plated parts that can cause excessive corrosion of the system.
