Installation and Operation Manual RTC 12i - www.regulus.eu
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 12i 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. 1335 l/h (0.37 l/s)
.
3.7. Electrical wiring
Electrical connection and any interventions in it may only be carried out by a qualified person with
the appropriate authorization!
-
Check that the power supply to the utility room is sufficient and in accordance with
the project documentation, resp. according to valid standards and regulations. The
cross-section of the supply cable for the entire heating technology depends on the
application and the output of the auxiliary heat source.
