Dirt and deposits in the heating circuit can cause malfunc-
tions.
Install shut-off devices for the heating water outlet
(flow) and heating water inlet (return) on the heat
pump side…
By installing the shut-off devices, the evaporator and
condenser of the heat pump can be flushed, if neces-
sary.
Connect the unit to the fixed piping of the heating
circuit via vibration isolators. You must install them to
prevent the transfer of structurally borne sound to the
fixed piping.
NOTE.
Vibration isolators are available as accessories.
1 Heating water inlet connection (return)
2 Heating water outlet connection (flow)
Lay the condensate hose in the unit so that it cannot
come into contact with the refrigerant pipes.
Check that frost-free condensate discharge is ensured.
Installation plan for the respective model.
Heat pump planning & design manual.
Seal empty pipes on the unit side.
CONDENSATE DRAIN
The condensate precipitated from the air must be removed
frost-free via a condensate pipe with minimum 50 mm
diameter. If surfaces are water permeable, it is sufficiency
for the condensate water pipe to be laid vertically in the
ground to a depth of at least 90 cm. If the condensate is
discharged into drains or sewers, ensure frost-free laying
with a gradient.
Hook the upper facing panels into the unit cover.
Screw the bottom onto the unit frame…
The air deflector hoods are now installed. You can
carry out the assembly and installation work on the
unit, and when finished attach the bottom facing panels.
(See “Electrical connection work”)…
In case of lengthy work interruptions, attach the facing
panels to close off the unit.
INSTALLATION / CONNECTION TO THE HEATING CIRCUIT
ATTENTION
Integrate the unit in the heating circuit as shown in
the hydraulic diagram for the respective unit model.
It is not possible to connect several heat pumps in
parallel.
“Hydraulic integration” documents.
Check to make sure that the cross-sections (diameters) and
lengths of the pipes for the heating circuit (including the
pipes laid in the ground between the heat pump and the
building!) are adequately dimensioned.
The hydraulic system must be equipped with a buffer tank,
the required volume of which depends on your unit model.
see “Buffer tank” page 15 .
ATTENTION
When installing the connections, always protect the
connections on the unit from twisting, in order to
prevent damage to the copper pipes inside the unit.
Flush the heating circuit thoroughly before connecting
the unit to the heating circuit…
