Avoid any shocks during lifting or ground removal that could damage the structure and the integrity of the unit.
If the unit is lifted using a crane, use a rudder and belt it to keep in a horizontal position.
Do not obstruct the opening of the side doors during the ceiling mounting of the unit.
Support areas under the central part:
•Recessed from doors seals and latches
•From the lower edge of the front panel to the lower edge of
the rear panel.
VIII.3. Installation precautions
Make sure that there is no obstacle in front of the blow jet:
•If the ceiling is sloping, it is recommended to install the unit on the upper part of the slope
•There should be no beams perpendicular to the blow jet
•If there are light fitting protruding from the ceiling, the air stream must be able to pass over the light fittings so that it is
not blocked.

VIII.5. Installation et fixation to the ceiling
EVERSKY unit must be installed exclusively indoor, on the ceiling (with or without false ceiling).
Install the unit in such a way that bad weather or ambient temperature cannot damage the internal elements. No water inlet from
outside must be made possible: make sur to install awnings or rain grilles at the fresh air inlet or at the extract air exhaust and to
leave a slight slop from the inside to the outside on the ducts of fresh air supply and extract air discharge.
Make sure to keep the airtight of the building at the core holes between the wall and ducts:
•On the outside: fill the gap between the duct and the core
•On the inside: fill the gap between the duct and the core or place a seal between the wall and the face concerned of the
unit.
Before any operation, check that the installation supports are suitable to support the weight of the unit with all accessories and
option.
The mounting bracket must always be attached to the top panel in order to ensure the tightness of the unit.

Step
Description
1
Remove the bracket from the top panel of the unit by
unscrewing the 4 fixing screws.
Note: the position of the bracket thus fitted at the
factory corresponds to the clamping position once
the un unit is leaning against the wall.
This position may refer to the prior dimensions taking
depending on the installation configuration chosen.
2
Check the presence of clamping nuts on the threaded
rods of the fixing support (nuts to be engaged
approximately 10mm after the end of the threaded
rods).
3
Draw 2 markers on the ceiling:
•1 line 120mm from the wall to which the unit
is leaning
•1 line perpendicular to the first above and
centered in relation to the 2 cores made in
the wall.
4
Align the edge of the support on the first line and
centered the frame on the second line by means of
the holes (B) acting as markers (templates plates (A)
can optionally be removed beforehand to facilitate
the installation of the frame and rewound
afterwards).
5
Attach the frame by means of 4 x 4 fixing holes (C).
6
Attach the 2 template plates on their ends by means
of fixing holes (D).

VIII.5.b. Installation of the unit on its support
Step
Description
1
Place the unit in horizontal position (doors below and blowing grid at the front) and remove the transport supports.
2
Lift the unit and bring it close to its
final position about 80mm from the
wall and 80mm from the ceiling. (In
this step, the screws (E) are still set
back from above the unit)
3
Adjust the position of the unit
laterally using the 2 template plates
acting as visual guide/marker.
4
Raise the unit until it is flush with
the ceiling.
Engagement of threaded rods inside the unit
5
Move the unit backwards until it is
leaning against the wall.
6
Open the side doors to tighten the
nuts inside the unit so that the unit
can be placed correctly against the
ceiling and its trim adjusted.
7
Arrange the removable port / blind panels from inside according to the configuration of the installation (see I.5 Airflow
connections).

VIII.5.c. Installation of the unit in a false ceiling
The unit can be semi-recessed in a false ceiling (mounting (A)) up to 10mm above the blowing grid frame.
(A) Mounting in contact with the ceiling
(B) Offset ceiling mounting
The unit can also be offset from the ceiling (B).
In this case, remove the 4 screws (E) M10x70 et replace them with a M10 threaded rod. Allow the threaded rod to protrude 70mm
below the support.
Ensure that the attachment of the threaded rod in the ceiling is strong enough to support:
-Weight of the unit itself and any options mounted on it
-Installation loads
-Operation/maintenance loads
VIII.6. Access inside the unit
The EVERSKY unit has 3 independent, recessed and hinged doors for access to the interior.

Connect power supply wires directly on the main switch terminal (marker 1 and 3).
Connect the protective earth (PE) wire on the crimped nut near the main switch (provide a eyelet lug for M6 screw).
The protective earth wire must be slightly longer than the line and neutral wires.
Power supply connection to the main switch
Attach and clamp strongly the power supply cable to a fixed part (frame, cable tray…).
IX. ELECTRICAL CONNECTION OF EXTERNAL DEVICES
The EASY control embedded in the EVERSKY unit provides the user with specific inputs and outputs to know or force the operation,
or to possibly control remoted devices.
IX.1. Alarm report output (DO5) - 24Vac to be relayed
Factory setting = NO (Normally Open) output
Output in idle state (open) = no active alarm or presence of Class
C alarm (warning).
Active output (closed) = Class A or B alarm is active.
See XX.7 List and meaning of alarms.
24Vac output to be relayed.

IX.2. Heating output (DO3) - 24Vac to be relayed
Only for Premium BC and Infinite BC unit versions.
Factory settings = NO (Normally Open) output.
24Vac output to be relayed.
The DO3 digital output is activated when the control identifies a
need for heat to comply with the temperature setpoint. This all-
or-nothing signal can be used to control, for example, the
operation of a circulator/pump, or a heating generator.
The DO3 Output gives 0Vac when it is inactive, 24Vac when it is
active.
The maximum current is limited to 100mA. The output must be
relayed to power a component whose consumption exceeds the
maximum current.
The status of the DO3 digital output is associated with the state of the analog output AO1 used for controlling the 3 ways valve of
the hot water heating coil.
IX.1. 3-way valve control output (AO1 –0-10V)
Only for Premium BC or Infinite BC unit versions.
The operation of AO1 analog output is associated to the operation of the DO3 digital ouptput.
The signal of the AO1 analog output is 0-10V type. It reflects the heating requirement calculated by the unit’s controller according
to the programmed temperature setpoint and the actual measured temperature via a PI (proportional/integral) control loop:
This signal can be used, for example, to control external devices (3-way modulating valve, heating modulating generator…) that
provides heating for the room. The unit is acting as a room thermostat.
