Fire requirements
$Q\ȴUHVDIHW\UHTXLUHPHQWVPXVWEHFODULȴHG
The positioning of heat sources must be coordinated
with extract air valves so that heat is not sucked straight
out through a valve or door gap.
1.2. PLUMBER
(if the unit has a water battery)
Water pipe layout and placement of the water battery
(channel battery) must be planned. These must be kept
warm to avoid frost damage. A closing damper with
spring must be used. See separate instructions (116166)
that accompany the water battery.
The water battery must be located
in a room with a drain.
1.3. ELECTRICIAN
Power supply
The units have an approx. 2 m cable with plug and
require a single-phase earthed socket nearby. Plug
requirements: 10 A. We recommend a separate circuit
for the unit.
For permanent installation, it is possible to
use a fuse in the installation network, provided that it is
DSSURYHGDQGLWPXVWEHSRVVLEOHWRVHFXUHLWLQWKHR΋
position. Or a separate approved service switch can be
installed.
!
It is important for the plug to be
accessible for servicing when the
unit is fully installed.
The unit should be installed with
an earth fault breaker.
When using the app:
The unit must be connected to the internet or an access
point for local communication with the app. A conduit of
at least Ø20 mm is recommended between the unit and
the home’s router for the network cable.
When using the control panel:
Lay a Ø20 mm conduit for running the cable for
controlling the unit between the unit and an easily
accessible place in the home (e.g. outside the bathroom)
DQGWHUPLQDWHZLWKDȵXVKPRXQWHGVLQJOHZDOOER[
Locate the control panel here. The control cable must
be located min. 30 cm away from any power cables. The
control cable must be max.
24 m long to ensure a signal.
For use with accessories:
Lay a Ø16 mm conduit between the unit and the

pressure relay, etc.).
NB! The PG nipple for the power cable must be tightened
with a torque of 2.0 Nm if the cable is replaced.
