Installation

7.1 General Information

The following connections need to be established on the heat
pump:
- Fresh and exhaust air
- Flow and return flow of the heating system
- Condensate outflow
- Voltage supply
- Temperature sensor

7.2 Air Connection

ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
The glass fibre reinforced concrete air ducts offered as accesso-
ries are moisture-resistant and diffusion-free (exhaust air duct
600 x 600 and inlet duct 750 x 750). When using the air duct for
the air outlet side (600 x 600), the "insulating mat duct connec-
tion" (in the accessory pack) is to be adhered to the air outlet on
the desired connection side.
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts are not screwed directly onto the heat pump. Only
the rubber seal comes into direct contact with the heat pump
when the system is installed correctly. This guarantees easy as-
sembly and disassembly of the heat pump and also ensures that
solid-borne sound is well insulated.
If an alternative air duct is being used to that which has been sup-
plied as an accessory, care must be taken to ensure that it does
EN-6
not reduce the cross sectional area of the air intake and air outlet
sides. The "small and large sealing rings" included in the scope
of supply can be used for sealing the heat pump connection.
They also function as vibration isolators.
The large sealing ring can be used to position the air intake open-
ing of the heat pump directly onto an appropriately constructed
wall opening.
It must be ensured that the interior side of the wall opening is
lined with thermal insulation to prevent the wall from becoming
cold and to prevent moisture from penetrating the wall.
When very short air ducts are used on the air outlet, the exterior
side of the wall opening must be fitted with a safety guard or an
air deflector grille suitable for preventing body parts (fingers or
arms, especially those of children) coming into contact with the
ventilator in the heat pump.
If flange-mounted air ducts are used, connecting stubs are se-
cured on the air inlet and air outlet sides with 4 M8 hexagon bolts
in the threaded holes provided (the hexagonal long nuts). When
doing this, ensure that both air duct stubs only touch the insula-
tion. There should be no contact with the external sheeting.
Care must also be taken to ensure that suitable vibration isola-
tion and duct insulation are provided.
