product.
Once installation is complete, leave this manual in the machine for future reference.
The installation of this product (implementation, connections, commissioning, maintenance) and all other
interventions must be carried out by a professional applying the rules of the art, the standards and the
safety regulations in force.
It must comply with the requirements relating to Electro Magnetic Compatibility and the Low Voltage Di-
rective.
The manufacturer cannot be held liable for any injury and/or material damage caused when the safety
instructions have not been respected or following a modication of the product.
UTBS ECOWATT
®
PRO-REG single-ow units are intended for single-ow ventilation and air treatment
applications in kitchens or tertiary buildings.
Indoor (recommended) or outdoor installation:
• Maximum permanent environment temperature: -20°C / +40°C.
• To avoid any damage to the electronic components (very low temperature, condensation) the safety
switch located on the front panel must be kept in the “ON” position, except during maintenance pe-
riods.
• Relative humidity: max. 95% without condensation.
• Non-potentially explosive atmosphere.
• Low salinity atmosphere, free from corrosive chemical agents.
1.2 Safety instructions
General
• Meaning of the danger labels present on the access doors:
Live equipment Rotating machine Potentially ammable dusty f ilters
• Put on appropriate PPE (Personal Protective Equipment) before any intervention.
• Before installing the air handling unit, ensure that the support and location are strong enough to
• support the weight of the unit and accessories.
• Do not open doors or panels without shutting down the unit.
Case of emergency or danger
• Switch o󰀨 the power supply using the lockable disconnect switch and, if possible, the main circuit
breaker.

5/64 NT00000850-UTBS-ECOWATT-PRO-REG-ETD2-AN-230623
AHU normal shutdown procedure
• Stop the unit from the ETD2 remote control or the BMS to allow ventilation of the electric heater, if pre-
sent, before stopping the fans and the AHU. See § "8.2 Stop the air handling unit", page 42.
• Switch o󰀨 the power supply using the lockable disconnect switch and, if possible, the main circuit
breaker.
• Make sure that moving parts are stationary.
Before starting, check the following points:
• Check the earth connection.
• Check that the access doors are properly closed.
Tripping of safety thermostats (EI model)
• UTBS ECOWATT® are equipped with 2 safety switch thermostats:
-A manual reset thermostat switches off the heater at 85°C.
-An automatic reset thermostat switches off the heater at 60°C.
• Any resetting or tripping information (via the BMS for example) involves looking for the cause of this
triggering on the AHU and on the installation. Contact [email protected].
1.3 Reception – Storage
In the event of lack, non-compliance, total or partial damage to the products delivered, the buyer must, in
accordance with article 133-3 of the Commercial Code, issue written reservations on the carrier's receipt
and conrm them 72 hours by sending a registered letter to the transporter and a copy to the manufacturer.
The receipt without reservation of the equipment deprives the Buyer of any further recourse against us.
The product must be stored away from bad weather, shocks and dirt due to projections of any kind during its
transport from the supplier to the end customer, and on the site before installation.

ment of parts or equipment whose operation is recognized as defective by the manufacturer, excluding
any compensation or penalties. The costs of labor, removal and rest, travel related to the replacement are
the responsibility of the Customer. Excluded from our warranty are linked to abnormal use or not in accor-
dance with the recommendations in our instructions, defects observed as a result of normal wear and tear,
incidents caused by negligence, lack of monitoring or maintenance, defects due to incorrect installation of
devices or poor storage conditions prior to assembly.
In any case, manufacturer is not responsible for transformed material, even partially repaired.

3.3 Handling and lifting
I mini
I
The units are delivered screwed onto pallets made to the
dimensions of the box.
The handling of UTBS ECOWATT
®
air handling units can
be done by pallet truck, forklift or crane. The handling
equipment will be adapted to the load and the lifting
conditions.
In all cases, the lifting will be done at the base of the device
xed on a pallet.
The device should be handled with care and only in a
horizontal position.
3.4 Location and mounting
Pitches
UTBS ECOWATT® AHU must be xed to a at, smooth surface capable of supporting the weight of the
unit in operation and its accessories. The EXD and EXG models are intended for installation outside the
premises.
The air handling unit must be xed by the brackets provided for this purpose. Mounting on anti-vibration
compression or suspension mounts and with exible connections is recommended.

Floor
Attention:
• For electric heater version (EI), only positions A, Band
C are possible.
• For cold water and reversible coil version (EF, ECF,
ER), only positions Aand C are possible.
• For hot water coil version (EC), positions A, B, C, Dand
E (bottom xed to the wall) are possible.
For the installation of a unit with vertical air ow (version B or D), the unit must be xed to the wall so that
the accessory casing under the unit (if present) does not support the entire weight of the unit.
No obstacle must hinder or prevent the good circulation of supply and extract air.
Access for maintenance
UTBS ECOWATT® AHU can be ordered with dampers and right hand/left hand connections (depending on
the airow direction).
Access to the lters can be done by their side panel or the lower or upper panels depending on the as-
sembly of the unit.
Access to the electrical box is made from the side panel.
To remove coil or heater, it is necessary to remove the relative side panel and slide the coil or heater until
it is completely extracted from the unit.

To avoid the transmission of engine vibrations to the building, it is necessary to install anti-vibration mounts
at each xing point. Use the anti-vibration kits recommended in the following table:

The angle brackets are used to join the di󰀨erent modules
together. If the device is made up of several modules, a
connection kit, consisting of 4 bolts and a seal, is supplied
with the module added to the main module.
3.5.1 Damper and cover
The ID registers must be xed with the screws provided in
the frame of the UTBS.
The cover must be xed with the self-drilling screws
provided on the frame of the UTBS.
If there is an ID damper, unscrew the damper xing screws,
overlap the cover and reinstall the screws.
Access to the actuator is via the side cover.
