I RECEPTION OF T E EQUIPMENT
The units are delivered on stringers or pallets then wrapped in plastic film.
I.1 Checks on reception
When the appliance is received, the state of the packaging and the equipment must be checked. In the event of damage,
make an accurate note of any problems on the carrier’s delivery note.
I.2 Storing
The appliance must be stored in shade, in a dry place, at a temperature between -20°C and 40°C.
II INSTALLATION
II.1 andling
The appliances must only be moved to their installation position.
If the appliance is handled using a fork-lift truck, ensure this supports the load-bearing structure and does not touch the
panels enclosing the unit.
If the appliance is moved using a crane, use four cables of identical lengths. These must be at least as long as the
greatest distance between two fastening points.
If L (length) + W (width) + (height) > 5 m _, then the case must be lifted using a lifting beam.
II.2 Space required
Generally speaking, it is desirable to provide access space of at least the width of the unit on the access side for
maintenance. These units require a siphon and must be installed at a sufficient height to allow this to be fitted.
Note: for vertical units, allow at least 300 mm on the rear for connecting the condensate drain fittings.
II.3 Installation
The unit must be laid on a sufficiently rigid and flat surface (use vibration dampers if necessary). or the HVAC connection,
select duct sections based on the dimensions of the pipes, which must be properly extended.
Install the unit in such a way that bad weather or room temperature cannot damage the internal items of the unit during
installation or subsequent use (provide a protective cap if possible).
Installing the unit on the floor: the unit must be laid on a sufficiently rigid and flat surface (use vibration dampers if
necessary). or these units, provide a gradient of 2 to 3% for the removal of condensate in the direction of the width.
(connect the condensate drainpipes as per section II.4).
Installing the units outdoors: or raising the unit above the ground (protection from water), a set of feet can be supplied
as an option (NRG EC E C). A roof (NRG EC RRC) and rain cowls (NRG EC RRO) must also be provided if necessary and
are available as options. or these units, provide a gradient of 2 to 3% for the removal of condensate in the direction of
the width (connect the condensate drainpipes as per section II.4).
In compliance with current regulations, the machine must be installed only by a technical person qualified for this type
of work. During installation, ensure that:
- The machine is handled as specified in section II.1.
- The required personal protection devices are worn so as to avoid injuries caused by electrical and mechanical
hazards (injuries by touching panels, sharp edges, etc.).
- Electrical connections are made after the power supply has been shut off, in compliance with the recommendations
given in section VI.
- The unit is grounded in compliance with the regulations in force.
- The machine is powered up after completion of installation (ducting installed and inspection doors closed).

Installing the units on the ceiling: the units must be mounted preferably on a frame suspended from the structure of the
building, taking care to comply with load limits (the frame is the installer’s responsibility).
or these units, provide a gradient of 2 to 3% for the removal of condensate in the direction of the width. (connect the
condensate drainpipes as per section II.4). The 3000 model can be suspended directly from the ceiling by means
of M8 threaded rods connected to the attachment lugs on the lower part of the unit.
Before starting the unit, check the tightness of all bolts, particularly those of rotating components
II.4 Siphon
Provide a siphon on each condensate drainpipe. Each siphon can be used for one drainage system only. Note: the siphon
must be connected in accordance with best practices in order that condensate is removed as
efficiently as possible.
The height H must be at least equal to the maximum internal negative pressure of the unit (p in mm).
Example: Dp = 500 Pa 50 mm CE
_H > 50 mm 2H > 100 mm

The electric board is located in the vicinity of the return air duct.
VI.2 Electric supply and wire section
The VORT NRG EC units are connected with either 230 V / 50 Hz single phase or with 400 V / 50 Hz three phase + neutral
(see table below for power supply cable selection). The power supply is directly connected to the local circuit breaker (the
labels show you where to connect the neutral on the circuit breaker). The earth wire is directly connected to the insert
located on the door or on the band of the electronic control module.
The unit may malfunction due to wrong choice of wire section. The wire section must be selected
according to the regulations in force in the country of destination of the appliance.
VI.3 Connection of the probes
All the components are factory-connected to the power supply terminal board, except the temperature probes, which
are connected directly to the CORRIGO regulator.

VI.8 Bypass
This function is automatically controlled using the CORRIGO regulator’s programming and the probes installed as
standard in our VORT NRG EC units.
In winter (FREE EATING): When heat is required, the bypass closes to recover maximum calories through the plate
exchanger. If this recovery is not adequate to reach the temperature set-point, the water coil valve (if available) will open
or the electric coil (if available) will start.
In summer (FREE COOLING): The bypass closes when the outside temperature is higher than the inside temperature
to prevent the outside heat from entering directly. If the outside temperature is lower than the inside temperature, the
bypass opens to get the cool outside air.
On the VORT NRG 6000-8000 models, the single servomotor is wired in the same manner as the small shutter.

VI.9 NIG T COOLING
This function is used during summer to cool buildings at night by using cool outdoor air, thus reducing the cooling power to be delivered
during the day. The NIGHT COOLING function works only between midnight and 7 a.m..
During the Night Cooling period, the heating and cooling outlets are blocked. The bypass is also open to prevent air from
travelling through the exchanger. At the end of a NIGHT COOLING period, the heating is blocked for 60 minutes.
Operating conditions:
•The outdoor temperature was greater than 22°C during the day.
• The clocks are set either to LS or to stop between midnight and 7 a.m..
• The outdoor temperature is less than 18°C during the NIGHT COOLING period.
• The outdoor temperature is greater than 10°C during the NIGHT COOLING period.
• The room temperature is greater than 18°C.
During the NIGHT COOLING period, the fan runs at 85% capacity. This speed can be adjusted. See section VII.3.7
or the LOBBY version, a maximum 24 V 2A output is provided between the DO7 and 2 terminals to force the opening
of the dampers during the Night Cooling period.
VI.10 Automatic defrost
This function is automatically controlled using the CORRIGO regulator’s programming and the probes installed as
standard in our double-flow VORT NRG EC units. Defrosting starts with the opening of the bypass (defrost temperature,
SDG, less
than 5°C). If the bypass function is not adequate to defrost the exchanger (normally if the outside temperature is less than
-10°C), the new air fan modulates its airflow until it stops, and then restarts as soon as the defrost temperature probe
exceeds 5°C.
For the INFINITE and E versions: a defrost coil is installed on the new air duct, to minimise the risk of frost with the
bypass closed. The maximum efficiency of the system is thus maintained.
VI.11 ot water and cold water coil (the valve must be connected in the OFF position)
On the VORT PREMIUM BC and VORT INFINITE BC versions, the hot water coil is already installed in the unit. The anti-
frost thermostat is connected. However, you should wire the 3-way valve.
or all other versions, also connect the THA (anti-frost thermostat) and shift the supply air probe after the battery
Connect the 3-way valve’s servomotor as follows:
Hot coil:
Terminal 20 of the VORT NRG EC unit to the +24 V (G) of the valve’s servomotor
Terminal 21 of the VORT NRG EC unit to the +0 V (G0) of the valve’s servomotor
Terminal 22 of the VORT NRG EC unit to the +10 V (Y) of the valve’s servomotor
Connect the NC contact (C and 2) of the T A (anti-frost thermostat) to 18 and 19
Cold coil:
Terminal 26 of the VORT NRG EC unit to the +24 V (G) of the valve’s servomotor
Terminal 27 of the VORT NRG EC unit to the +0 V (G0) of the valve’s servomotor
Terminal 28 of the VORT NRG EC unit to the +10 V (Y) of the valve’s servomotor
Connect the NC contact (C and 2) of the T A (anti-frost thermostat) to 18 and 19
VI.12 Changeover coil (EC FIRST versions only) (the valve
must be connected in the OFF position)
A changeover coil can be installed on the VORT NRG EC FIRST version. In
this case you will not be able to add another hot water or cold water coil. You should connect the 3-way valve, the
changeover handle and the THA (anti-frost thermostat), and shift the supply air
probe after the coil
Connect the appliance as described below:
Red wire of the handle (CO) to Y of the valve’s servomotor
Terminal 20 of the NRG EC unit to the +24 V (G) of the valve’s servomotor
Terminal 21 of the NRG EC unit to the +0 V (G0) of the valve’s servomotor
Terminal 22 of the NRG EC unit to the brown wire of the handle at the hot signal
Terminal 28 of the NRG EC unit to the black wire of the handle at the cold signal
Connect the NC contact (C and 2) of the T A (anti-frost thermostat) to 18 and 19
