,. HANDLING
• When unit received, unpack and make sure the packaging is intact; any defect may indi-
cate damage to the equipment. Review it carefully to make sure that no parts are mis-
sing.
• If there is any damage to the unit or the shipment is not complete, write down the pro-
blems on the delivery slip and send a claim to the carrier. Also report any problems to
S&P.
Filtering section
The filtering section has one flat filters made from galvanised steel frame.
This section includes an specific rail to fit a second filter (supplied as an accessory).
Prefilters
Mounting system via rails included.
Available prefilters (accessories): G4/M5.
Final filtration
Mounting system via fast-clamps that allow a perfect thightness with the unit frame.
Standard filter (supplied with the unit): F7.
Available filters F6, F8 or F9 filters with an efficiency level above 60%.
The filters have been manufactured according to UNE 779:2013.
• Components should be transported using appropriate hoist and slings. The equipment
has corner lugs for loading and unloading.
• The UTBS PRO-REG units are delivered bolted in pallets.

10
-.1. OVERVIEW
• The technician responsible for equipment receipt must ensure that the characteristics of
the existing power supply agree with the electrical data on the unit’s identification plate.
• Before installing the equipment in its final position, make sure that the place where it
will be located is strong enough to support its weight.
• Under no circumstances should these units be installed in flammable or explosive envi-
ronments, in environments that contain oil vapours, salt air, or corrosive environments.
• Equipment installation can present hazards due to the material used, pressures in the
system and the electrical components. For this reason, only trained and qualified service
personnel may install service or repair the equipment.
• As a precaution, when performing operations inside the equipment, shut off the power
at a main breaker. This serves to prevent any accidents involving the equipment’s moving
parts, which can start accidentally, well as to prevent any direct or indirect contact with
live parts.
• When installing the unit, it must be levelled to allow for a good fit between the different
modules, perfect condensate drainage and proper opening of the doors.
• To test whether the fan is in perfect condition, check the centering of the intake ring by
turning the impeller by hand.
• It is possible to manipulate by the unit using a forklift or crane. Handling machines must
be adapted to the conditions of loading and lifting. In all cases, the lift must be carried out
from the base of the device. The centre of gravity is NOT in the center of the unit. Before
lifting the equipment ensure that gravity center of the device is entering the two blades
of the forklift.
• The unit should be handled carefully and only horizontally.
7. INSTALLATION

11
-.3. INSTALLATION SITE
• Avoid installing the unit in areas near heat sources or in damp areas where the unit
might come in contact with water.
• It is recommended that the unit be installed in a place that is easily accessible for the
installation. Provide sufficient room for maintenance, connection and drainage of con-
densate.
-.4. MAINTENANCE SPACE
• The installer should leave sufficient unobstructed space to allow free access to the unit
for maintenance. The amount of space needed will depend on which side of the unit is
performing the extraction. The unit is equipped with some side access doors for access
to the filters and fans. To remove the coils, the side panel must be removed. Both the
filters and the fans can be removed from either side of the unit.

7.5.3. MIXING MODULE INSTALLATION
The mixing module is installed in the intake air side and allows to realize the the mixing
between the outdoor air and the recirculated air with proportional regulation of existent
dampers in either air intakes.
The mix module and the corresponding servomotors are supplied both as accessories.
The installer should mount the damper module, using the screws and bolts supplied with
the unit.
After that, mount the servomotor on the damper shaft.
Once mounted the servomotor, make the electrical connection between the servomotor
and the electrical cabinet according to the indications in the electrical diagram.
Check that the rotation sense of the actuator is correct. If it is necessary, modify the dam-
per rotation sense via the selector in the frontal of the actuator
7.5.4. INSTALLATION WITH ISOLATION DAMPER
To realise the unit isolation of the ductwork, each time that the unit is stopped, it is possible
to install one isolation damper in the unit inlet:

20
Both the damper module and the corresponding servomotors are supplied as accessories.
The installer should mount the damper module, using the supplied hardware with this.
Mount the servomotor on the damper shaft.
After mounting the servomotor, make the electrical connection to the electrical cabinet
according the electrical diagram.
Check that the actuator sense of rotation is correct (once the unit is stopped the damper
must be closed). If it is necessary, modify the damper rotation sense via the selector in the
frontal of the actuator
• Air (inlet section: >i^s sent with a fixed position of the dampers. If not coincide with the
needs of the installation, change the frontal panel as shown.
