Connecting the air hoses

Note
In the case of heat pumps installed indoors, if a blower
door test to EN 13829 is to be carried out, apply Proce-
dure B (checking the building envelope). This involves
closing or sealing off all apertures which are purposely
provided in the building envelope before the air hoses
are installed.
f Seal off the wall outlets for the blower door test. f
Note
Air hoses guide the intake air to the appliance and route
the discharge air from the appliance to the outside. These
air hoses are highly flexible, thermally insulated and are
self-extinguishing in case of fire.
f Connect the air hoses to the function module using the wing f
nuts contained in the pack.
f Use rawl plugs and screws that are suitable for the wall f
structure to attach the air hoses.

10.1 Preparation

Note
The heat pump with function module is designed for in-
stallation in interiors, except in wet areas.
By installing the supplied pressure hoses to connect the function
module and the heat pump, you do not need to install any addi-
tional pressure hoses externally as anti-vibration mounts.
10.1.1 Electrical installation
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
The connection to the power supply must be in the form
of a permanent connection. Ensure the appliance can be
separated from the power supply by an isolator that dis-
connects all poles with at least 3 mm contact separation.
This requirement can be met by using contactors, circuit
breakers, fuses/MCBs, etc.
Note
The specified voltage must match the mains voltage.
f Observe the type plate. f
f Use cables with the relevant cross-sections. Observe the ap- f
plicable national and regional regulations.

The electrical data is listed in chapter "Specification" in these oper-
ating and installation instructions and in the heat pump operating
and installation instructions. For the BUS cable you will need a
J-Y (St) 2x2x0.8 mm² cable.

Provide separate fuses/MCBs for the three power circuits,
i.e. those of the appliance, the control unit and the elec-
tric emergency/booster heater.
