3. GENERAL STANDARDS
• Product risks have been analysed pursuant to the provisions of the Machinery Directive.
This manual contains information intended for all personnel exposed to hazards, with
the goal of preventing personal injuries or damage to objects resulting from mishand-
ling or improper maintenance. All maintenance service work (corrective and preventive)
must be performed with the equipment stopped and disconnected.
• To avoid danger of possible accidental start up ensure that the equipment is electrically
isolated and locked. If this is not possible, warning signs should be placed on main dis-
tribution console that state:
“WARNING: controls disconnected for maintenance”
• Before connecting the power cable to the motors, make sure that the voltage on the line
matches the voltage indicated on the unit’s identification plate.

,. 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 a specific system to fit a second filter (supplied as an accessory).
Mounting system using threaded knobs, which provides great tightness with the equip-
ment frame.
Standard filter (supplied with the unit): G4
Filters available as an accessory (M5, F7, F9).
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 UTV-ECOWATT units are delivered bolted in pallets.

-.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.

-.3. INSTALLATION SITE
-.2. IDENTIFICATION KD?JF7HJI
The main module may consist of three different sections: filter, coils and fans. However,
one of the first two sections may not be included. The following illustration identifies the
main components of the main module.
Electrical cabinet
Breaker
Heating battery
Cold battery
Drain
Fan section
Battery section
Filtration section
The unit must be installed so that the airflow is upright vertical position: Bottom air
intake and top discharge.
• 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.
