• In the event that the ventilation unit was transported in a tem-
perature lower than 0 °C, it is necessary to leave the unit for
at least 2 hours without turning it on, allowing the tempera-
ture inside the unit to be levelled to the temperature of the
surrounding area.

3. MAIN COMPONENTS
2.1 CHECK THE SUPPLIED UNIT
DO NOT MISS!
• Check immediately on delivery, that the packaged product
is not damaged. In the event of damaged packaging, consult
the haulier.
• In the event that any reclaim will not be applied in time, future
applications will not be processed.
• Check if the product type is the one you have ordered. In the
event that it is not the ordered unit, do not open the pac-
kaging and report the fault to the supplier immediately.
• After unpacking the product, check that the units and acces-
sories are in order. If you have any doubts, contact the supplier.
• Never try to operate a damaged ventilation unit.
• In the event that you decide not to unpack the ventilati-
on unit immediately after delivery, the product must be
stored in a dry interior with a temperature ranging from
+5 °C up to +35 °C maximum.
• This product is not intended for use by persons (including chi-
ldren) whose physical, sensory or mental incapacity or lack of
experience and knowledge in the safe use of products when
they are not supervised or, if they were not instructed on the

12.5 mm, not protected from water!)
6.1-1 Built up dimensions
The unit must be installed in such a way that the direction of
the air ow throughout the unit corresponds with the air ow
in the distribution system.
The unit must be installed in such a way that the direction of
the air ow throughout the unit corresponds with the air ow
in the distribution system.
6.1.-2 Required distances
ATTENTION
Non-ammable materials must not obstruct the suction and
exhaust openings.
• The safe distance of ammable materials from the entry neck
of the unit is 500 mm.
• The safe distance of ammable materials in the remaining
directions is 100 mm.
6.1.-3 Mounting of the unit
500 mm
380 mm
• These dimensions are recommended for servicing access.
TECHNICAL INFORMATION
• All types of ventilation units can be installed in following
positions:
• Any other position is prohibited.
• The unit must be installed in such a way that the direction of
the air ow throughout the unit corresponds with the air ow
in the distribution system.

6. INSTALLATION
ATTENTION
• Threaded rods must be able to take the weight of the unit!
• Considering the weight of the unit, it is necessary to use
suitable lifting equipment (a fork lift truck etc.) or use
two or more persons who will hold it up until it is safely
mounted
• Measure up the place of installation
• Drill the holes into the wall and hang the unit on threaded
bars on all corners of the unit.
YOU WILL NEED
• 4 wall plugs according to type and size of the screw (also
depending on the ceiling material and the weight of the unit)
• Electric drill and drills of the relevant size
6.2 CONNECTING THE CONDENSATION
wATEr OUTLET
YOU WILL NEED
• drain hose 1/2“
h1=150mm
The remaining holes blind
by plugs.
Connect the siphon on to the neck and the drain pipe which will
lead to the sewerage system.
DO NOT MISS!
• Check whether the unit is tilted so the condensate may run o
freely (we suggest 5° tilt, see the gure below).
• The siphon must be connected and sealed properly in the
heat exchange unit.
DO NOT MISS!
Check the following prior to the rst activation of the ventilation
unit:
• That unit is correctly attached to the framework.
• That unit is closed properly, all of the necks are connec-
ted to the pipelines or protected with a grid and therefore
there is no risk of injury from rotating or hot parts.
• Electrical connections must correspond with wiring dia-
gram.
• That all electrical components are correctly connected.
• That condensation water outlet is connected to the drai-
nage
• That installation corresponds with all instructions from
this manual
• That there are no tools or other objects left inside the unit
which could damage it.
• Whether unit includes a clean lters.
ATTENTION!
• Interventions and changes to the internal connection of the
unit are prohibited, they may lead to warranty loss.
• We suggest using the accessories supplied by our company.
In case of any doubts in use of the original accessories please
contact the supplier.

DO NOT MISS!
• The connected pipes must be of the same diameter as the ex-
haust and suction necks. If pipes of a smaller diameter will be
used, the unit performance could drop and in some cases the
lifespan of the ventilators could also decrease.
• Any joints between the air distribution pipes and the unit
must be sealed using a sealant or a sealing tape.
• The minimum distance of the bent air pipes or adapting pie-
ces from the unit neck should be 500 mm.
6.3-2 Protective grid
In the event that some of the necks of the unit will not be used
for connecting pipes, it is necessary to x the opening with a
grid for protection from touching the rotating parts of ventilator,
heater bars etc..

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 qualied 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
