• Fans can exceed speeds of 1000 rpm. Do not insert any objects or hands into electric fans.
• We recommend installing an omnipolar safety circuit breaker near the unit, which can be easily reached to cut off the power. Before any cleaning or maintenance, cut off the power to the unit.

- Before opening the unit, make sure that all electric supplies have been cut off. In particular, make sure that the fan is off and cannot be started inadvertently prior to opening inspection panels.

- CHECK THE EARTH CONNECTION!!

• This unit may be used only for the purpose for which it is intended: heating, cooling, ventilation and air treatment of domestic, residential, commercial and industrial sites in which the air condition can be considered good/standard/normal. It should be used only for treating air with “civil” temperatures and low levels of pollutants, industrial fumes, chemical fumes, salts, powders, oils, fats, relative humidity (R.H.) and aggressive substances. Any other use must be considered improper and therefore dangerous, (besides starting corrosion/abnormal wear, bonding/binding/locking motors/fans/bushings/bearings and moving parts, obstructing filters/coils/etc., and therefore dramatically reducing the efficiency and life of the unit).
• The main risks arising from improper maintenance and/or use are mostly electrical (short circuit, electric shock, overheating and igniting fire), thermal (overheating and igniting fire), mechanical (projection of moving parts, overheating due to friction and consequently igniting fire) and water-related (water leakage, flooding and damage to structures and furnishings).
• In particular, the standard unit is not suitable for use in the agricultural sector (e.g. greenhouses with high R.H., fertilizers, nitrogen, chemicals and pesticides sprays, etc.), salty environments and the livestock sector (e.g. farms with acid atmospheres, high R.H., nitrogen, ammonia, sewage, biogas, etc.), food industries (air with high levels of volatile organic compounds, acid vapours, chlorides, yeasts, etc.), marine areas (air with high levels of chloride, salt, corrosive substances, etc.).
  For similar applications, ask for specific units that are designed for a specific use (e.g. units with a high IP level, ATEX units, units with condensate drain pan and/or casing and/or coil and/or other components made of AISI304L or AISI316 stainless steel, are painted, etc.).
• Beware when starting up units: do not start units on sites where other operators are still finishing construction site work (mounting/cutting/smoothing/painting plasterboard/floors/false-walls/furniture/furnishing/etc., and construction work in general): the atmosphere may be full of different types of dust and pollutants (including chemicals) that could quickly damage the unit, even seriously.
• Should the unit work in a house where disabled people and/or children and/or animals live, it must be located safely out of their reach. Always make sure that the access door to the inside control board remains locked.
• The unit can be used by children older than 8 years or by people with diminished physical, sensory or mental capacities, or those without experience or the necessary knowledge, provided they are supervised or have received instructions on using the device safely and are aware of the risks it poses. Children must not play with the unit. Cleaning and maintenance intended to be carried out by the user must not be done by children without supervision.
• Wrong installation may cause harm to people or animals, or damage to property for which the manufacturer will not be held liable.
• The manufacturer shall not be held liable for any damage caused by improper, incorrect or unreasonable use.
• In the event of failures or malfunctions, deactivate the unit and do not attempt to repair it, but ask for the assistance of the installer.

- If you are going to leave the unit off for a long time, first make sure that it cannot harm anyone in any way.

- PLEASE DO NOT FORGET THAT THE WARRANTY CANNOT BE APPLIED IN THE EVENT OF ELECTRICAL OR MECHANICAL MODIFICATIONS, OR TAMPERING IN GENERAL!!

• The unit must be installed in such a way as to guarantee full accessibility for routine and special maintenance, including easy replacement of any component and/or replacement of the entire unit. The manufacturer shall not be held liable for any costs or expenses incurred as a result of failure to comply with these requirements.
• Any false ceilings must allow removal of the bottom and front panels on the unit for inspection and maintenance, and to replace the filters, fans, coil, regulation devices and electrical equipment.
• On the water connection side of the unit, leave at least 200 mm for installing the pipes and valves.
• For the other 3 sides of unit leave at minimum 100 mm free space for inspection/maintenance.

INSTALLATION: DUCT CONNECTIONS

Renewal system and remote air distribution

The side openings allow the separate realization of an external air intake duct for the renewal and of an air hose duct for an adjacent room.

Fresh air

Remove the film on the sheet indicated with letter "A".

Use the flange ∅72mm (optional) and connect the pipe with anti-condensate insulation; the use of a fan for the duct (optional) must be provided with non-return valve and filter to prevent dust.

Remote air distribution

Remove the film on the sheet indicated with letter "B".

Use the flange ∅155mm (optional) e connect the pipe for air distribution in the adjacent room.

It is recommended the closing of the air vent on the panel in correspondence of the duct of remote air distribution.

Air supply adjacent room 103 B D.155 285 103 60 D.72 Air-a A

• The ducts must be sized according to the system and air flow characteristics (ESP) of the unit fans. Miscalculating the ducts would cause loss of power or could trigger devices in the system.
• In order to attenuate the noise level, the use of cased air ducts is recommended.
• The initial section of the air supply duct should be twice as long as the shorter side of the duct before curves, branches or obstructions such as shutters, otherwise the unit performance will suffer.
• Branching sections should not be angled by more than 7^ .

In compliance with the European ECODESIGN directives and regulations, the ducts must be properly sized (large sections, few and slight changes of direction, etc.) in order to guarantee low pressure drops (pressure drops are always a source of waste and energy dissipation, with consequent loss of performances and energy efficiency in the unit and in the system in general).

- The air intake and supply ducts must always have a larger section (or the same, but never smaller) than the air intake or outlet on the unit, otherwise the @ESP performance will drop (due to air pressure drops).

EN - 8

INSTALLATION: WATER SUPPLY CONNECTIONS

- WARNING:

when connecting the coil to the pipes, always use anti-torsion systems (e.g. a spanner and counter-spanner), and tighten with the correct tightening torque, to avoid breaking the coil.

For water coil versions: Make the water connections

• In compliance with the European ECODESIGN directives and regulations, the pipes must be properly sized (large sections, etc.) in order to guarantee low pressure drops (pressure drops are always a source of waste and energy dissipation, with consequent loss of performances and energy efficiency in the unit and in the system in general).
• The water connections must be made using pipes with a larger diameter (or at least equal, but never smaller) that the water connections on the unit!
• Install shut-off valves (of suitable dimensions, MIN 3/4") to isolate the coil from the rest of the circuit in the event of special maintenance. Connect the inlet with a shut-off ball valve and the outlet with a balancing or lockshield valve (or install 2 shut-off ball valves).
• Install a breather valve above and a discharge valve below.
• Mandatory: appropriately insulate water valves and pipes to prevent dripping in cooling mode.
• The water heat exchanger coils are tested at a pressure of 30 Bar, and can therefore operate at a maximum pressure of 15 Bar.

Tightening torque (Min .... Max)
Unit (coil connection) A 3/4": 10...14 Nm
Regulation valve B 3/4": 8...12 Nm

Cool 3/4" Heat 3/4" OUT IN OUT IN 80 50 4 pipe unit

Heat/Cool 3/4" OUT IN 50 80 2 pipe unit

Please note that the main causes of coil failure are:

• Breakage/cracking of welds or pipes due to abnormal mechanical shock (e.g. impact and/or forcing during handling, transport and especially during installation), in particular forcing during assembly caused by tightening too vigorously without the use of anti-torsion systems such as a spanner and counter-spanner.
• Excessive thermal expansion of the water supply pipes (different temperature between hot/cold water), expansions that in certain circumstances (e.g. pipes that are too long) may become evident and therefore dangerous if they discharge on the unit manifolds.
• Weights, transmission of vibrations or deformations of the pipes in the supply system acting on the unit manifolds.

- MANDATORY: therefore, depending on the features of the system (to be evaluated on a case-by-case basis), use brackets, expansion joints, anti-vibration systems and all other precautions required to prevent the weights, deformations and vibrations of the return pipes from acting on the unit manifolds.

Risk of freezing:

Install antifreeze devices if the unit, drain or plumbing connections may be subject to temperatures close to 0^ C (e.g. protect the pipes with heating cables under the insulation, insulate the pipes, etc.). If the unit is installed in areas with particularly cold climates, empty the water from the system during long system shutdown periods.

INSTALLATION: CONDENSATE DRAIN

For versions used in cooling with condensate generation:

• Mandatory: appropriately insulate condensate drain pipes to prevent dripping in cooling mode.
• Install an appropriately sized condensate drainage system, position it to favour drainage (min. 3% slope), and ensure it has no rising or narrow sections in order to allow regular outflow.
• Mandatory: install a siphon in condensate drainage system.
• Connect the condensate drain to rainwater drainage system.
• Do not use waste water or sewage drains to prevent unpleasant odours from returning into the room if the water in the siphon evaporates.

3 cm/m

Pipe MIN. Ø 16mm MAX 1,00m OUT OUT IN IN 43 25

The drainage system should feature an adequately sized trap to:

• Allow the condensate to drain freely.
• Prevent inadvertent entry of air into the circuit under negative pressure.
• Prevent inadvertent leakage of air from the pressurized circuit.
• Prevent entry of unpleasant odours and insects.

- NOTE:

The trap should have a plug to facilitate cleaning of the lower section, and be easy to disassemble.

AUXILIARY DRAIN PAN MOUNTING (optional)

The auxiliary drain pan collects the condensate formed near the water connections and the valves.

Fix the auxiliary drain pan to the structure with the 2 screws provided in the position shown in figure, making sure pipes and insulation do not tilt it, hindering the drain.

EN - 10

(non-exhaustive) prescriptions are given below. Refer to the electrical system design for further details.

- WARNING:

make sure that electrical power to the unit is turned off before carrying out any work.

- Please do not forget that the warranty cannot be applied in the event of electrical or mechanical modifications, or tampering in general.

• Observe the EEC safety regulations and the regulation/laws in force in the country of installation.
• Make sure that the mains specifications comply with the data indicated on the unit identification label.
• Power supply for the unit and accessories (motor, electric heater, remote controls, regulation, etc.): Check that the mains supply voltage is within the established limits (see operating limits).
• Operating the unit with voltages that are not within the aforementioned limits invalidates the warranty.
• Make sure that the electrical system is able to supply the current required by the electrical household appliances already in use in addition to the working current required by the unit.

CHECK THE EARTH CONNECTION

• The unit is electrically safe only when it is correctly connected and properly earthed according to the safety standards in force.
• When making the connection, the earth cable must be longer than the live ones. It will be the last cable to come away if the power cable is accidentally pulled, thus ensuring good earth continuity.

CONNECTION CABLE SPECIFICATIONS

• Make all connections to the unit using cables of adequate size for the power used in accordance with the local laws in force. Their size must be such that the phase voltage drop is less than 3% of the nominal voltage.
• Use H05V-K or N07V-K cables with 300/500V insulation in pipes or ducts.
• For units with an inverter/driver or other frequency-varying device, use shielded cable.
• All cables have to be in pipes or ducts until they are in the terminal board of the unit.
• The cables must not be pulled or twisted as they leave the pipe/duct. They must be protected from the weather. Always use stranded cables with ferrules. Make sure that all individual strands are correctly inserted in the ferrule.

ELECTRICAL CONNECTION AND OMNIPOLAR RESIDUAL CURRENT CIRCUIT BREAKER

- ALL WIRING DIAGRAMS ARE SUBJECT TO UPDATE:

IT IS ADVISABLE TO REFER TO THE WIRING DIAGRAM ACCOMPANYING THE UNIT.

• It is mandatory to rely on a designer and use first class, certified components suited to the specifics of the system in which they must be installed, and to the characteristics of the components mounted on the unit/accessory to be powered.
• Make the electrical connections according to the unit wiring diagram.
• The use of adapters, multiple sockets and/or extension cords is not permitted for main power supply to the unit
• To prevent short circuits, the unit should be connected to the power supply line via an appropriate omnipolar residual current circuit breaker with a minimum contact opening of 3 mm. This circuit breaker is intended to ensure adequate overload protection (thermal part) + short-circuit protection (magnetic part) + protection against electric leakage, electric shock or earth fault (residual current part). See the electrical absorption on the unit label to choose the most suitable circuit breaker.
• Remember: an omnipolar circuit breaker is a switch capable of opening both the phase and neutral. This means that when the switch is opened, both contacts are open.
• The omnipolar circuit breaker or the plug (connection by means of cable and plug) must be mounted where they are easy to reach.
• It is always advisable to install an additional fused cut-off switch upstream, that besides offering additional protection, completely isolates the electric line with a contact gap of at least 3 mm when the fuses are removed.
• The installer is responsible for installing the unit as close as possible to the main power cut-off switch!!

- ELECTRICAL ABSORPTION:

Refer to the electrical absorption on the unit serial number label.

Accessories, remote controls:

When installing the control panel, choose an area where the maximum and minimum ambient temperature limits are respected (0–45°C, < 85% R.H.). Do not install the control panel on a metal wall if it is not permanently earthed.

ROUTINE MAINTENANCE (TO BE CARRIED OUT BY THE USER): MONTHLY CHECKS

- NOTE:

Adequate maintenance ensures safety and savings!

For environments with “normal” levels of cleanliness, it is advisable to carry out the following operations at the beginning of each cooling and heating season, and thereafter at least once every month of operation:

- CLEANING:

Clean the external parts of the unit simply using a damp cloth.

- AIR FILTER:

Clean the ter mat simply by beating it, washing it with water and detergent, or using a jet of compressed air.

IMPORTANT: when cleaning the Alter, make sure that the water/air jet passes through the media in the opposite direction to that of normal operation, and ensure that it is not strong enough to damage the Alter media. If alters are washed with water, dry them in the open air before re-installation in order to avoid compromising system efficiency.

To clean air □ter, follow the procedure below:

• With the help of a ☐at-blade screwdriver rotate of 90° the locks placed on the intake grid of the front panel as shown in previous ☐gure.
• Remove the □iter from the inner rails, being careful not to break.
• Once cleaned, re-insert the Alter into the guide and close the grid by turning the locks of 90° in the opposite way than the opening.
• Always reassemble the □iter after cleaning it before restarting the unit.

- CONDENSATE DRAIN:

During the summer season, check that the condensate drain is not obstructed and that the pan is clean and free of dust or anything else. Any dirt may obstruct the drain, causing the condensate to overflow. If it is dirty, request the intervention of the after-sales service.

ROUTINE MAINTENANCE (TO BE CARRIED OUT BY QUALIFIED PERSONNEL): YEARLY CHECKS

The ensure the unit is kept in good working condition, periodic maintenance is mandatory at least once a year. Remember that maintenance must be carried out by qualified personnel only. The first annual check on the unit is carried out entirely by the qualified maintenance technician, with the related responsibilities.

- CHECKING THE ELECTRICAL PARTS:

Check all electrical equipment, and in particular the tightness of the electrical connections. Check the electrical absorption.

- CHECK THE TIGHTNESS of all nuts, bolts and ranges that may have been loosened by vibrations.

- VIBRATIONS/NOISE:

Check that the unit operates without vibrations or abnormal noise.

- VENTILATION CIRCUIT INLET/OUTLET:

Check that they are not obstructed, which lead to overheating the windings.

- FAN/MOTOR UNIT:

Both the motor and fans rotate on self-lubricating bearings that do not need maintenance. Make sure the impeller is clean. Check that the fan is free of dirt and foreign bodies. If this is not the case, clean it using compressed air, taking care to avoid damaging the impeller.

- MOTOR:

Make sure that there are no traces of dust, dirt or other impurities on the motor. Any dust/dirt entering the moving parts (especially bearings/bushings/etc.) could cause the components to seize/bind, increasing resistance to movement and eventually blocking the system, overheating the motor, or causing burning or damage.

- AIR FILTERS:

In addition to routine cleaning/maintenance to be carried out by the user, replace all the air filters at least once a year or 3,000 hours of operation.

- WATER COIL:

The heat exchanger coil must be kept in perfect condition to guarantee the technical design specifications. Check that the nned wall has no obstructions to airflow; if necessary, clean it and be careful not to damage the aluminium ns. To clean it, use a little brush or a vacuum cleaner, which is even better.
