8. Connection
8.1. Technical air connection
8.1.1. Without air duct
Without an air duct, the device must be installed in a
room of at least 20 m³.
If the clear height under the ceiling above the device
is less than 40 cm, it is advisable to install a bend on
the air outlet and to direct it to the rear or to the sides.
The domestic hot water heat pump can also be used
in unheated workshops and garages if the parameters
listed in chapter 7 "Installation location" are complied
with.
The domestic hot water heat pump enables dehumid-
ification and cooling of rooms such as laundry rooms
and storerooms.
8.1.2. Intake and air outlet using air duct within
buildings
By using an air duct on either the intake or outlet site
it is possible to take in air from an adjacent room (e.g.
from a laundry room to dehumidify it) or to route the
outlet air into an adjacent room (e.g. into a store room
to cool it).
A connection with two air ducts is also possible as an
option to allow air intake or outlet from or to two dif-
ferent rooms.
8.1.3. Intake or air outlet with outside air
The operating range of the domestic hot water heat
pump covers an air temperature range of -7 °C to
max. +45 °C. The domestic hot water heat pump takes
in heat energy from the outside air. As a result, it is es-
sential to route the air ducts for intake and air outlet
outside into the open air to prevent frost damage in
the air outlet room during the winter months.

NOTE
Total length max. at Ø 160:
6 m for flexible pipe, 12 m for smooth pipe
1 bend = 1 equivalent metre
The domestic hot water heat pump should be con-
nected using air ducts with an internal diameter of
160 mm.
With a 90° cell foam (EPP) pipe Ø 160 mm the posi-
tion of the ducts connected to the device can be
aligned in all directions (360°).
8.1.4. Accessories for duct connections
The optional accessories available for the duct con-
nection are designed for easy and high-performance
connection of the domestic hot water heat pump.
Item 1 and item 2
The air duct 1 (IS R 160 – 370650) and the bends 2 (IS
BG 160-90 – 370660) are made of cell foam (EPP),
and are semi-rigid, lightweight and heat insulating.
Item 3
They are connected using a connector 3 (IS VM 160 –
370670).
