The electrical connection is established on the separating plate
behind the "upper front panel" (illustration). Remove the screws
and the upper side panelling to access the connection space:
The cable entry is located on the rear panel of the device. All ca-
bles inserted from the outside must be installed in the strain re-
lieves provided on the device.
The "upper side panel" (2) and the "upper front panel" (1) must be
removed to insert cables or sensors from the outside. The "cover
panel" (3) must also be removed.
Dismantling order:
1)
Remove the "upper front panel" (1) by loosening the (eight)
tapping screws (a) (the plastic cover caps must first be re-
moved)
2)
Loosen all four tapping screws (b) on the cover (3) and on
the "upper side panel".
3)
Loosen the two screws (c), swing the "upper side panel" (2)
away from rear panel (ca. 20 mm), push back the "upper
side panel" approx. 6 mm (as indicated by the arrow) and lift
(approx. 7 mm).
4)
To remove the "lower front panel" (4) (only necessary when
checking the corrosion protection anode or the heating ele-
ment), it is sufficient to loosen the lower two fastening
screws (d) and to push the "lower front panel" upwards 6
mm and then lift it off.

Supply connection
The power line (3 x 1.5²) for the heat pump and the heating ele-
ment is firmly attached to X1.
As an option, the heating element can be separately supplied
with power. For this purpose, the cable bridges must be removed
at X1 and X2 acc. to the circuit diagram. The power line for the
heat pump is then attached to X1, and the power line for the
heating element is attached to X2.
The requirements of the local utility company must be observed.
Remote control
The remote control is installed (surface-mounted) in an easily ac-
cessible location in the building (e.g. living room or kitchen). To
simplify connection, it is recommended to mount the casing on
top of a flush-type box (installation instructions are included with
the remote control).
The compact domestic ventilation unit (exhaust air) and the re-
mote control are connected on site via a 6-pole connecting cable.
The remote control must be connected according to the circuit di-
agram to operate the compact domestic ventilation unit (exhaust
air).
7.4 Connecting the Exhaust Air
System
Standardised exhaust air systems:
Standardized exhaust air distribution systems with decentralized
outside air valves are available for the compact domestic ventila-
tion unit (exhaust air). These systems are connected to the de-
vice using a flexible air duct equipped with sound and thermal in-
sulation (DN 160). This air duct is used for both the exhaust air
as well as for the outgoing air.
The installation instructions for the respective exhaust air system
must be observed.
If it is possible that the operating noise of the system might be
transmitted into exhaust air rooms located in the immediate vicin-
ity (e.g. in the case of very short air duct routes), an additional
suitable duct sound absorber (DN 160) must be installed on the
exhaust air side of the compact domestic unit.
Individual exhaust air systems:
If rigid ducts (e.g. folded spiral-seam ducts, flat ducts) are used
for the exhaust air system, a flexible transition (e.g. flexible duct
pieces with a length of approx. 1 m) must be used between the
duct system and the exhaust air and outgoing air stubs of the de-
vice to ensure that there is adequate vibration isolation.
A suitable duct sound absorber must be used on the exhaust air
side to prevent the operating noise of the ventilation unit from
being transmitted.
Important information:
To prevent contamination of the device and the heat ex-
changer, suitable exhaust air filters must be fitted in the air
duct system.
The exhaust air duct system must always be insulated with
water-proof insulation on the outside to prevent heat losses
and the formation of condensation when the system is
routed through rooms (e.g. attics, cellars, etc.) that are
colder than the extracted exhaust air.
