2 - RECEIPT
The installation and maintenance operations must be performed by qualied and experienced personnel.
Follow the operating precautions to the letter when working on the unit. Labels have been placed on the unit to remind you of
the safety instructions.
As a general rule, follow all applicable safety regulations and standards.
Damage to the 39HX dual-ow air handling unit will be disregarded in case of failure to follow the instructions in this document.
Each unit has a name plate bearing an identication number. This number must be quoted in all correspondence.
In accordance with Article 133-3 of the French Code of Commerce, the recipient is entirely responsible for checking the condition of
the goods received. In the event of missing items, the customer must provide the exact number of parcels delivered. Any damaged or
missing items must be specied on the delivery note in the presence of the driver before signing the delivery note. These comments
must be conrmed to the carrier by registered letter within 3 business days. The comments "conditional" and "pending unwrapping"
shall have no value. The customer must unwrap the goods in the presence of the driver. Claims must be made at the time of delivery
and be described in detail.
The unit must be stored in its packaging and sheltered from weather.
39HXC, 39HXE, 39HXEZ and 39HXV
• The 3 sizes of the 39HXV model and the size 1000 of the 39HXC, 39HXE and 39HXEZ models are packaged units, delivered
mounted on feet.
• Sizes > 1000 for the 39HXC, 39HXE and 39HXEZ models are multi-block units, delivered assembled. The blocks can be split
in order to facilitate their passage through doorways (see splitting procedure in the HANDLING part).
• Sizes 100 and 150 of the 39HXEZ model are delivered in 2 blocks. You are responsible for assembling these yourself on site.
Quick connectors enable the electrics for these blocks to be connected quickly and easily.

3 - HANDLING
The unit can be handled by slings, lifting beam or stacker.
In all cases, the lifting point has to be at the base of the unit. For packaged units or assembled multi-block units, the centre of gravity
is at the centre of the unit.
This operation will be performed by qualied personnel.
The unit must be handled with care, and only in the horizontal
position. If the unit is handled by a lifting beam + slings, tubes
need to be placed in the holes provided in the support feet.
Ensure that the crane hook adapter is large enough to prevent
the belts applying any pressure to the AHU casing. Furthermore,
ensure that the steel tubes are secured to prevent any movement.
If the above-mentioned lifting methods cannot be used, the unit
may be lifted using a forklift truck, taking great care not to dent
the lower panel (use forks of a su󰀩cient length).
Follow the applicable handling rules.
39HXC, 39HXE and 39HXEZ models
Procedure for uncoupling 39HX multi-blocks or assembling the 2 blocks for the 39HXEZ 100 & 150
1 Remove the 4 nuts and screws
2 Undo the screws on each beam and remove them.

5

3 Disconnect the electrical connectors on the control and disconnect switch.
4 You can now separate the blocks.
Note: Follow the procedure in reverse to re-couple the blocks, particularly for the 39HXEZ100 & 150.
When uncoupling the blocks, ensure that the 18X10 PVC gasket located between the blocks remains correctly in place
to guarantee a perfect seal. If necessary, t one.
NB: if there is a roof, remove it rst in accordance with the instructions given on the roof tting plan (see technical specications).
39HXC, 39HXE, 39HXEZ and 39HXV models
These models are placed directly on a at, smooth oor. The atness value must be the best possible, around one per thousand.
Under normal conditions of use, there is no need to x the unit to the oor.
The unit's support feet must be standing fully on their contact surface. It is important to allow su󰀩cient service space to facilitate
maintenance operations.

CO2sensor
The CO2 sensor must be positioned on the return air duct, so that it can measure the CO2 level emitted from the part(s) treated.
This sensor is supplied as a spare part and the manual for this is included in its packaging.
Operating principle
CO2sensor
To congure the CO2 level activation threshold, refer to the information on air quality for the town/city in which the AHU is installed.
CO2 concentration scale and the e󰀨ects on humans:
(Our CO2 sensor has an operating range of 0 to 2000 ppm)
CO2concentration E󰀨ect on humans
380 - 480 ppm Normal atmospheric level
600 - 800 ppm Correct level for enclosed spaces
1000 - 1100 ppm Tolerable level for enclosed spaces
5000 ppm Upper limit for 8 hours of exposure
* CO2 sensor (sensor in duct): refer to the attached supplier manual
Duct pressure sensor
The optional constant pressure mode is available in two versions
-Constant pressure on intake: the air intake fan is controlled to maintain the supply air duct pressure. The extraction fan copies
the intake air ow. It is possible to create an o󰀨set between these two ow rates by conguring the M factor between 0.5 and 1.5
(see control manual).
-Constant pressure on both ow rates: each fan is controlled independently according to the pressure of the associated duct
network. The intake and exhaust ow rates are not connected.
Two pressure values can be congured: Nominal pressure and Reduced pressure.
The ducted pressure sensor must be positioned on the duct
network at a distance: D = 2 Dh (hydraulic Ø)
• If the duct is circular, Dh = Ø of the duct
• If the duct is rectangular DH
4 - DESCRIPTION OF THE UNIT & TECHNICAL CHARACTERISTICS

To guarantee that the ducted pressure sensor operates correctly, it must be autozeroed before its system is started up.
To do this, power up the sensor, disconnect the tubing from the 2 pressure connections, marking their positions, and press the "Autozero"
button found inside the unit. Ret the two pressure tubes in their respective positions.
This autozero should be checked once a year.

5 - INSTALLATION AND INSTALLATION CONNECTIONS
The installation of the equipment must comply with the regulations and standards of the recipient country
The additional box must be positioned in the duct so that the temperature sensor is on the downstream side (air supply)
Special recommendations:
• Connections must not place mechanical stresses on the unit.
• Keep all inspection doors closed while the unit is operating
• If tted outdoors (39HXC, 39HXE and 39HXEZ models only), the units must be installed so as to withstand the climate conditions
in the installation location (risk of snow: height from ground/risk of wind: suitable xings, swan-neck type electrical connection
to the unit, etc.).
Flexible sleeve
Ensure all electrical components are earthed.
5.1 - OUTDOOR INSTALLATION (39HXC, 39HXE and 39HXEZ models only)
The installation of a 39HX dual-ow unit outdoors requires a roof and a canopy to be tted; these are usually supplied mounted* and
adapted to suit each conguration.
(* Supplied in kit form if delivery of the elements assembled is not possible)
Fitting the roofs:
The roofs of 39HX units are designed to provide su󰀩cient protection against adverse weather conditions, as they overlap the edge of
the unit by 80 mm.
Fitting procedure:
1 Fix the foam seal along the length of the unit. (50 x 20 foam seal).
2 Fix the roof panel(s) along the entire length of the unit.
