RESIDUAL RISKS
GENERAL
This section lists some of the more common situations which, being beyond the control of the manufacturer, could be a source of risk to persons or property.
DANGER AREA
The figure below highlights the area in which only authorised personnel may operate.
• External danger zone, identified by a precise area
around the unit and its vertical projection on the ground in the case of hanging unit.
• Internal danger zone, identified by the area that can
be entered only after having intentionally removed the protecting panels or parts of these.
HANDLING
If handling operations are undertaken without adopting all the necessary safety procedures and exercising due care, the unit can fall or topple, causing damage — possibly extremely serious — to persons and/or property, and to the unit itself. Ensure the unit is handled and manoeuvred as directed on the packing and in the present manual, and in accordance with local regulations. In the event of refrigerant gas escaping, refer to the “Safety datasheet” for the particular refrigerant.
INSTALLATION
Incorrect installation of the unit can result in water leaks, accumulation of condensate, escape of refrigerant, electric shocks, fire, as well as irregular operation or damage to the unit itself. Make certain that the installation is carried out only by a qualified technician, also that the directions contained in this manual are followed and local statutory regulations observed. In the event of the unit being installed in a site where there is even the slightest risk of inflammable gas escapes and consequently the possibility of such gases accumulating in area around the unit, the risk of explosion and fire cannot be discounted. Take every care and precaution when selecting the installation site. Installation on a structure not able to bear the weight and/or afford a secure anchorage of the equipment may cause the unit to fall and/or topple, resulting in damage to persons or property, or to the unit itself. Make certain that every care and precaution is taken when positioning and securing the unit. If the unit is easily accessible to children, unauthorized persons or animals, this is a situation that can give rise accidents and injuries, perhaps serious. Install the unit in a place where access is allowed only to authorized persons, or install barriers or guards preventing unauthorized entry.
GENERAL RISKS
A smell of burning, smoke or other indications of serious irregularity could signal the onset of situations liable to cause damage to persons or property or to the unit itself. Isolate the unit from the electrical power supply (red-and­yellow) switch. Contact an authorized service centre so that the source of the problem can be identified and remedied. Accidental contact with heat exchange coils, compressors, pressure pipelines or other components can result in wounding or burns, or both. Always wear suitable clothing, including protective gloves, when working in the danger area.
Maintenance or repairs carried out by unskilled operatives can result in harm or damage to persons and property, or to the unit itself. Always contact an authorized service centre. Failure to close the panels of the unit, or to check that all the fixing screws of the panels are properly tightened, can result in harm or damage to persons or property, or to the unit itself. Verify periodically that all panels are closed and made properly secure. In the event of fire, the temperature of the refrigerant can rise to the point that pressure will exceed safety levels and perhaps cause fluid to be projected. It may also happen that parts of the circuit isolated by closed valves will explode. Do not stand near safety valves, and never leave the valves of the refrigerant circuit closed.
ELECTRICAL SYSTEM
If the power line connecting the unit to the a.c. supply is incomplete, or if the connection is made with cables of incorrect cross section and/or with insufficiently rated protective devices, this can result in electric shock, toxicity hazard, damage to the unit or fire. All work on the electrical system should be carried out referring to the wiring diagram and to the directions given in this manual, and the system itself must be dedicated. Failure to secure the cover enclosing electrical components can lead to the infiltration of dust and water, ultimately causing electric shocks, damage to the unit, or fire. Always fasten the cover securely to the unit. If live metal parts of the unit are not connected properly to the earth system, they can cause electric shock or even death by electrocution. Make absolutely certain that the connection to the earth system is made in accordance with correct practice. Contact with live parts rendered accessible internally of the unit when the guards are removed can result in electric shock, burns or death by electrocution. Before exposing these parts, make certain the isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign. Contact with parts that could become live when the unit is started up can result in electric shock, burns or death by electrocution. When there is no need for circuits to be powered up, set the isolating switch on the power line to the OFF position, padlock it and post a warning sign.
MOVING PARTS
Contact with the fan rotors can cause injury. Before removing the protective grilles or the fans themselves, make certain the isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign. Before removing the protective grilles or the fans themselves, make certain the isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign.
WATER SYSTEM
Defects affecting pipelines, connections or valves and other control componentry can result in water being leaked or sprayed from the system, occasioning damage to property or causing short circuits in the unit. Make certain all hydraulic connections are securely made, following the directions given in the present manual.

WATER CONNECTIONS
GENERAL
Piping must be designed with the least possible number of bends and head variations. If the pressure chute of the installation is above the useful prevalence of the pump, the water delivery capacity is reduced as well as, as a consequence, the thermal exchange and the yield.
INTERCEPTING VALVES
Install on the input and output of the user parts (exchangers, coils, humidifiers, etc) So that it will be possible to carry out all the service operations and possible substitutions without emptying the installation.
PRESSURE AND TEMPERATURE INDICATOR
Install on the input and output of the user parts (exchangers, coils, humidifiers, etc) So that it will be possible to carry out all the service operations.
AUTOMATIC OR MANUAL ESCAPE VALVES
Install the highest points of tubes in a way that the air can escape form the circuit.
BLEEDING COCK
Install them at the lowest points of the circuit, so as to allow emptying.
LEAKAGE TESTS
Before performing the insulation of the tubes, carry out a leakage test.
TUBE INSULATION
All tubes of water must be insulated so that to avoid the formation of condensation and thermal dispersions along the tubes themselves. Verify that the insulation is the vapour coil type. The connections for the air escape and for the emptying must be out of the insulating thickness to assure the accessibility.
CONDENSATE DISCHARGE CONNECTION
CONNECTIONS SUPPORTS
The weight of the hydraulic connections must be supported in the exterior of the unit so as not to stress the connections of user devices (exchangers, coils, humidifiers, etc ) .
ANTI-VIBRATION DEVICES
In case of units with anti-vibration devices, it is necessary to assemble elastic joints, even on water connections.
RISK OF FREEZE
If the unit and the relevant water connections are subject to temperatures near 0°C:
• mix the water of the system with glycol
• protect the tubes with heating cables under the tubes
insulation
• empty the system by verifying that:
o no taps are closed so they can not trap the water,
even after emptying
o there are no low points where the water can
stagnate even after emptying; blow if necessary
INSTALLATION EMPTYING
The refilling of the water present in the installation increase the oxidation phenomena and lime deposits.
If necessary empty only the interested system section and anyway empty or refill the installation if necessary .
EXPANSION TANK
The installation must be kept at the right pressure by both an expansion tank and a combined valve of pressure reduction and discharge; if the components are present on the unit, they must be installed on the installation. The expansion tank must be dimensioned in function of the water in the installation.
MAX. WORKING PRESSURE = 10 Bar
ARIES EFFECTS AND AIR BUBBLES CAN PRODUCE
THE OVERCOMING AND CAUSE WATER DROPS.
The condensate must be dispersed to avoid damages to persons and property.
1. Unit discharge fitting : the connection must avoid the transmission of mechanical stresses and must be performed paying attention to avoid the damaging of the unit discharge fitting
2. Make a trap that, eliminating the depression caused by the fan, stops the return of gas from the discharge pipe (see the figure).
3. Connect the condensate discharge to a rainwater drain. Do NOT use sewerage drains, so as to avoid the return of odours if the water contained in the trap evaporates.
4. Finally, check that the condensate will drain correctly by pouring water into the tray stud.
WATER HEATING COIL
OPTIONAL - The position of the connections is shown on the dimensional drawing of the unit. The air valve is placed on the top of the coil manifold, it is used to eliminate possible air bubbles on the circuit. The discharge valve is placed on the bottom of the manifold, it is used to empty the coil if it is unused for a long period.
TO AVOID THE FREEZE FORMING INSIDE THE COIL
1. If the unit or the relevant water connection are subjects to temperatures next to 0°C see RISK OF FREEZE in the GENERAL WARNINGS paragraph.
2. The freeze forming is possible also in summer in abnormal operating conditions (ex. Insufficient air flow-rate for clogged filters). It is so recommended to glycolate or empty also in summer
M42740M4-02 02/10/08 page 9
AIR CONNECTIONS
Proper execution and sizing of air connections are essential for ensuring correct operation of the unit and an acceptable level of silence in the room.
When designing and creating ducts, consider PRESSURE DROPS, FLOW RATE and AIR SPEED which need to be compatible with the characteristics of the unit. Special consideration needs to be made for pressure drops that are greater than the unit's static pressure, which would lead to a reduction in flow rate resulting in unit shutdown.
the weight of the ducts must not be supported by the
connection flanges
place anti-vibration joints between the ducts and the
unit
the connection to the flanges and between the various
sections of the ducts must ensure an airtight seal, preventing leakage in delivery and return which would compromise overall system efficiency.
limit pressure drops by optimizing the path, the type
and number of curves and the branches
use curves with a wide radius. Consider whether it
might be useful to equip them with deflectors (especially if the air speed is high or if curves are tight)
FEATURES FOR DUCTS FOR TREATED AIR
1. The inner surface of the duct must be smooth and washable. It must not contaminate the air.
2. Thermally insulate the ducts and the flanges so as to prevent loss of energy and condensation build-up.
Proper distribution of air in the room is essential for ensuring comfort levels.
In the selection and positioning of grilles, outlets and diffusers, the following are to be avoided:
3. excessive air speed
4. formation of stagnant zones and layering
5. entry of cold air into the room
6. formation of localized currents (due to uneven air distribution)
7. excessive variations in ambient temperature in the vertical and horizontal planes
8. short circuiting of delivery air towards return air
For purposes of comfort, the following things need to be considered:
9. air diffusers must be selected by checking the sound power generated at nominal flow rate conditions
10. the disconnections to the diffusers are to be made using flexible elements
11. the return grilles must be amply sized
M42740M4-02 02/10/08 page 10

Perform a seal check at max. working pressure checking that no leaks are present.
Check that the shut-off valves in the circuit are in the "OPEN" position. Check that there is no air in the circuit. If required, bleed it using the vent valves in the system. Check that there are no ARIES EFFECTS in the transient (pump and / or valve activation/deactivation) When using antifreeze solutions, make sure the glycol percentage is suitable for the type of use envisaged.

ELECTRICAL SYSTEM
Check the proper tightening of the screws that fix the conductors to the electrical components in the board (during handling and transportation, the vibrations could have loosened them). Verify that the unit is connected to the ground plant. Control that all panels and protection devices of the unit are repositioned and blocked. Charge the unit by closing the sectioning device, but leave it on OFF. Make sure that the tension and net frequency values are within the limit of: 230 +/- 10% single phase unit; 400/3/50 +/- 10% three-phase unit Control the unbalancing of the phases: it must be lower than 2% . Example: L1 - L2 = 388 V, L2 - L3 = 379 V, L3 - L1 = 377 V average of the measured values = (388 + 379 + 377) / 3 = 381 maximum deviation from the average = 388-381= 7V Unbalancing = (7/381) x 100 = 1.83% = ACCEPTABLE Operating out of the indicated limits causes the loss of the guarantee as well as very serious damages.
VERIFY TENSIONS – ABSORPTIONS
Check that the temperatures of the fluids are included in the WORKING LIMITS.
If the controls of the previous paragraphs are positive, it is possible to restart the unit.
For information on the control panel, refer to the paragraph CONTROL.
While the unit is working (ATTENTION ELECTRIC RISK: WORK SAFETLY) check:
• Power supply tension
• Phase unbalance
• Total absorption of the unit
• Absorption of the single electric loads

REMOTE INPUT CONFIGURATIONS
Check used remote inputs are activated (ON-OFF etc.) as given in the instructions in the ELECTRIC WIRING chapter.
SETTING THE SET-POINT
Check if it is necessary to modify the set-points shown in the CONTROL chapter
AIR FLOW CHECK
The effective unit flow-rate is function of the aeraulic system characteristics. It is so necessary to check the air flow-rate and eventually to proceed with the appropriate calibrations on the system (dampers, diffusers etc) and on the unit (fan speed control, pulley calibrations etc in base of the unit type and its configuration). Before performing the check, make sure that the system has been completed in all its parts (derivations, dampers, grilles, diffusers etc) .

LOCAL OR REMOTE MANAGEMENT
The unit can be managed locally from the thermostat or remotely through the use of a RS485 serial line with MODBUS protocol.
ON
The unit can be switching on/off:
• by thermostat
• by digital input (set by parameter)
• by net (set by parameter)
OPERATION
The unit has 2 set-points: one for heating and one for cooling. The first one is automatically kept lower than the second one with a difference of at least 1°C. The regulation module compares ambient temperature with the set-point and tries to keep it as close as possible to it; therefore, it varies the fan speed, the water capacity or both of them according to the configuration.
The unit operating is enabled only if the water temperature:
• in WINTER is higher than 30°C
• in SUMMER is lower than 20°C
OPERATING MODES
The modules automatically commute in cooling or heating mode.

CHANGE OF AUTOMATIC MODE – 2-PIPE UNIT
In this mode, a neutral zone is foreseen when the unit is positioned in a CHANGE OVER status for a time sufficient to probe water temperature. The status is displayed by a “CO” flashing. After that time, if water temperature is out of limit, the H2O alarm is signalled.
Water temperature is detected (therefore, the cooling/heating modes are defined) only if power is demanded. In this operation type, COOLING and HEATING sets are activated simultaneously; when one of the set is bypassed, water temperature is detected and the mode is defined. When thermo-regulator sets are met, the last operation mode is displayed.
The set that is the opposite to the actual one is determined internally by the regulator by a constant that is defined ZoneChangeOver:
with unit in COOLING: set heating (opposite)= current set – ZonaChangeOver with unit in HEATING: set cooling (opposite) = current set + ZonaChangeOver

GENERAL DESCRIPTION
The room thermostat HID-TI2/TI3 (hereafter HID) is a device for recessed installation for the remote control of the unit to which it is connected. It is therefore not a MODBUS network thermostat. It can be connected to terminal units equipped with terminal.ROOM or terminal.SPACE electronics and makes it possible to set:
• desired humidity/temperature
• the desired type of ventilation
• a series of advanced functions for the unit to which it is connected
• display any error codes that correspond to alarms sent by the adjustment unit.
• In the HID-TI control there is also a temperature sensor that can be used as a remote sensor for the unit to which it is
connected.
OPERATING MODES
"Normal" operation, HID-TI connected to CLIVET-BUS:
• the HID thermostat shows the operating status of the unit to which it is connected
• periodically measure the temperature/humidity in the room where it is installed
• it is possible to use only the 4 front keys (user programming)
• "Nolink" operation, HID-TI not connected to CLIVET-BUS:
• the thermostat is powered by auxiliary power (a battery must be present)
• it is possible to access hidden keys for installer use
• it is a temporary mode that allows "advanced programming" of the unit.
INITIAL RESET
Insert the battery (auxiliary power supply) and then press the power on key [A] [A].
All display segments will come on for about 3 seconds. Then the display will show the firmware revision of the device. If the HID device is not connected to CLIVETBUS within one minute, it will go off. During this time, you can only use the hidden buttons for use by the installer. You can also use the HID device without a battery. The initial reset is carried out simply upon connection with the CLIVETBUS. After the initial reset, upon connection to the CLIVETBUS, the device goes into normal operating mode.
USER PROGRAMMING
User programming makes it possible to:
• choose the operating mode of the unit (heating, cooling, eco, fan)
• set the adjustment set point
• manage the fan speed manually or automatically
• enable/disable the floating shutter of the air supply (swing)
• display ambient temperature
• power on/off the adjustment unit
• activate/de-activate silenced mode

The water valve is opened when thermo­regulation is demanded: if the probe detects hot water, the resistors automatically become an integration body.
On the contrary, if after TimeValve is over,
water temperature is not suitable, the valve closes, the H2O alarm is not activated and the resistors are not activated. As soon as the probe detects that water

DEHUMIDIFICATION
The dehumidification control is managed by the network, which is an upwards system that uses one or more terminal units to dehumidify.
When the DeumiOn network variable is switched on 1, the unit is forced into cooling mode, even when the temperature set is
met (100% opened valve and minimum ventilation speed). This occurs to meet the humidity conditions decided by the network (detecting the relevant humidity by a room thermostat). The dehumidification process shown by the display is stopped when the following occurs:
• the DeumiOn variable is 0 (humidity conditions are met).
• Temperature is below the LowLimit, value; therefore, the process can start again only if ambient temperature > set-point
Temp and if there is still a demand.
The dehumidification process can not start if:
• The operation mode is the Heating mode.
• The unit is OFF.

ROUTINE MAINTENANCE
BEFORE UNDERTAKING ANY SORT OF MAINTENANCE OR CLEANING, DISCONNECT THE ELECTRICAL POWER SUPPLY TO THE UNIT, AND ENSURE THAT OTHER PEOPLE CANNOT RE-CONNECT IT .
All equipment is subjected to wear out. The maintenance makes :
1. keeps the unit efficiency
2. the components last longer
3. keeps their efficiency and limits breakdowns Therefore, it is fundamental to perform periodical checks: a few controls can be performed by the user (AUTONOMOUS MAINTENANCE) and they are mainly cleaning activities; otherwise, controls have to be performed by specialized technicians (INSPECTIONS).
The machine should have a log book used to keep track of the performed controls. This will make fixing up breakdowns easier. Take note of the date, type of control (autonomous maintenance, inspection or fixing up), description of the control, actions taken and so on.

• PLEATED FILTERS
• CONDENSATE DISCHARGE
• ROOM AIR TREATMENT COIL
AIR FILTERS
It is very important for the air treatment coil to be able to offer maximum thermal exchange. Therefore, the unit must always operate with the filters installed and clean. Cleaning and replacement of filters are very important in terms of health and hygiene. Operation with clogged filters leads to a reduction in the air flow rate, resulting in malfunctions and unit shutdowns. It may even cause the unit to break down. How often the filters need to be checked depends on the quality of outdoor air, unit operating hours, dust and number of persons in the rooms. As a guideline, cleaning should ideally take place between weekly and monthly. It is advisable to start with frequent checks, and to adjust the frequency based on how much dirt is discovered.
PLEATED FILTERS
1. Remove the closing doors
2. Carefully extract the filter so that no dust reaches the parts below
3. Wash the filtering mattress in warm water with a common detergent.
4. Carefully rinse it under water while preventing to pour water in the room
5. Dry the filter
6. Reinsert it to its seat
7. Reassemble the closing doors
Old filters, washing residuals and residual parts must be disposed of, according to the law in force.

Dust and deposits could cause obstructions. Clean the tank, pour some water into the tank and check water flows normally.
M42740M4-02 02/10/08 page 29
ROOM AIR TREATMENT COIL
ATTENTION: accidental contact with the fins of the exchanger may cause small cuts. When performing the following steps, use protective gloves. The finned surfaces of the cooling coils and especially the condensation collection trays are the places where micro-organisms and moulds most easily flourish. It is therefore very important to clean regularly with suitable detergents and disinfect with appropriate products as necessary.
STRUCTURE
Check the condition of the parts making up the structure. Paint so as to eliminate or reduce oxidation at the points in the unit where this problem may occur. Check that the panelling is fastened correctly. Poor fastening may give rise to malfunctions and abnormal noise and vibration.
DUCTING
Check the fixing screws and the operation of the anti-vibration devices in order to prevent the transmission of vibrations in the room.
FANS WITH BELT DRIVE
BELT
The tension of the belt can be adjusted by the worm screw on the slide connected to the electric motor, using a socket wrench or spanner. The belt is tensioned correctly when the tolerances defined in the enclosed sketch are respected. The tension of the belt should be checked after around 10 hours of operation.
Avoid the following situations:
1. Not sufficient tension, which causes slipping and overheating and, as a consequence, the reduction of service life.
2. Too much high tension, which subjects the belt to high stresses and, as a consequence, the reduction of unit life and an excessive stress on bearings and
PULLEYS
Avoid the following situations:
1. Pulleys not aligned.
2. Pulleys not parallel.
3. dirty pulleys; dust, grease, dirt deposited between the surfaces of the belt and of the pulleys can make the system operate in anomalous conditions.
4. Pulleys not straight.
5. Pulleys too small.
6. Pulleys broken.
7. Pulleys off-centre or unstable.
8. Pulleys worn.

MAINTENANCE INSPECTIONS
Foresee inspection assistance carried out by authorized centers or by qualified personnel. The inspections should be carried out at least:
• Every year for only the cooling units
• Every six months for the cooling and warming
units The frequency, however, depends on the use: in the event of frequent use (continuous or very intermittent use, near the operating limits, etc) or critical use (service necessary) it is recommended to plan inspections at close intervals.
For units equipped with safety valves, follow the Manufacturer’s instructions.
Verify periodically the cleaning of the safety valves and that oxidative / corrosive phenomena are not present, in particular for installations near the sea, in industrial areas or in rooms with a corrosive atmosphere.
The inspections to be performed are as follows:
• verify the power supply tension (when emptied or filled)
• inspect the electrical board (status of solenoid starter
contacts, terminal closings, the status of wiring and relevant insulations)
• inspect the absorption of the single electrical loads
• verify the cleaning and the efficiency of the exchangers
• inspect the cleaning of the filters (air/water)
• verify the leakage from the refrigerating circuit
• Verify the protection devices (safety valves, pressure
switches, thermostats, etc.), the adjustment systems, the control devices (alarm signalizations, probes, manometers, etc)
• check the operating parameters of the refrigerating circuit (see the following REFRIGERANT TABLES and the START-UP section)
PUT AT REST
If a long period of inactivity is foreseen, for example the winter for the cooling unit, the following is recommended:
• to turn the power off in order to avoid electrical risks or damages by lightning strike
• to avoid the risk of frosts as shown in the HYDRAULIC CONNECTIONS section, and, in particular
- to empty or add glycole in the plant sections subjected to temperatures below zero
- to empty or add glycole in the water heating coils, also in summer
- - to power antifreeze resistances if present
If the period of inactivity is particularly long or in the event of extremely low temperatures, the external fans can be blocked temporarily; therefore, it is recommended to switch them on every month in order to avoid seizures or electrical overloads when the unit will be switched on.
The restarting of the unit has to be carried out by qualified personnel, in particular, after the winter break for cooling units or when seasonal switching should be performed.
When restarting, refer to the SWITCHING ON section.
Schedule technical assistance in advance to avoid hitches and be able to use the installation when necessary.

TROUBLESHOOTING
THE OPERATIONS MUST BE CARRIED OUT BY TECHNICAL QUALIFIED PERSONNEL HAVING THE REQUISITES UNDER LAW REQUISITES AND IN CONFORMITY WITH THE SAFETY REGULATIONS IN FORCE.
THE INTERVENTIONS WITHIN THE WARRANTY PERIOD WILL BE CARRIED OUT BY AUTHORIZED SERVICE CENTERS.
BEFORE RESETTING AN ALARM, IDENTIFY AND ELIMINATE ITS CAUSE. REPEATED RESETS MAY CAUSE SERIOUS DAMAGES.
In certain machine configurations, some safeties may be placed in series and lead back to a single input on the electronic module.
Therefore, check on the electrical diagram whether the device to which the alarm corresponds has other devices or safeties connected in series.
DECOMMISSIONING OF THE UNIT
DISCONNECTING THE UNIT
The units must be disconnected by authorised personnel, who before proceeding must first read the Residual Risks section in this manual.
Before disconnecting the unit, the following must be recovered, if present:
• the refrigerant (if the circuits cannot be isolated): the refrigerant must be removed using suction devices operating in a closed circuit, so as to ensure that none of the compound is released into the atmosphere.
• the antifreeze in the circuits: when removing this fluid, make sure that it does not leak and that it is not released into the environment. The antifreeze fluid must be stored in special containers.
When recovering the substances present in the unit, all measures must be taken to avoid damaging persons and things and polluting the surrounding area.
Awaiting dismantling and disposal, the unit can also be stored outdoors, as bad weather and rapid changes in temperature will not cause damage to the environment, if electric, cooling and hydraulic circuits of the unit are integral and closed.
DISMANTLING AND DISPOSAL
THE UNIT MUST ALWAYS BE SENT TO AUTHORISED CENTRES FOR DISMANTLING AND DISPOSAL.
When dismantling the unit, the fan, the motor and the coil, if operating, may be recovered by the specialist centres for reuse.
All the materials must be recovered or disposed of in compliance with the corresponding national standards in force.
For further information on the decommissioning of the unit, contact the manufacturer
