6.4.ELECTrOINSTALLATION
AND ELECTrICAL FITTINGS
ATTENTION
• The main electrical supply must be turned o prior to any
interference with the internal parts of the ventilation unit!
• The electro installation of the ventilation unit must be
implemented according to the technical documentation
issued by a qualied electro engineer. The actual installa-
tion can be carried out by a professional educated in the
electro eld. The manual instructions must be observed
as well as the valid national regulations and directives.
• The electrical charts featured on the product have a
higher priority than the charts included in the manual!
Prior to installation, check if the marking of the termi-
nals conform to the electrical chart for connection. In the
event of any doubts, contact your supplier and under no
circumstances should you connect the ventilation unit.
• The unit must be connected to the power supply using in-
sulated xed and temperature resistant cable according
to the diameter and the relevant national regulations and
directives.
• Any interference and amendments into the internal co-
nnection of the unit are prohibited and can lead to a loss
of the warranty service.
• Correct unit functioning is guaranteed only with original
ttings

The heat recovery unit must be connected using the TN-S
system which means that the neutral wire must always be
connected. All electrical circuits into the heat recovery unit
must be connected via a protective power circuitbreaker
according to the current and type. The distance in between
the open contacts must be bigger than 3mm.
Heat recovery unit must be connected in such a manner so
it can be disconnected from the power supply via a single
element. Table of the minimum dimensioning of the power
supply cables and circuit breakers according to the type of
heat recovery unit.

6.4-2 Electrical ttings
Connect the unit electrical ttings to the terminal inside the
regulator box exactly according to the el. diagram for conne-
ction and according to the markings of the terminals.
DO NOT MISS!
• The connection diagram is glued to the internal side of the
removable lid of the regulator box.
• Each element must be connected using an original cable or
cable as per the specication for each element.
• To open the lid of the regulator box you will need 2,5mm
imbus key. See picture.
