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.

A = 2000mm B = 2000mm

C = 2000mm D = 2000mm

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.

M03I40M7-03 15/11/07 page 7

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.

REFRIGERANT

In the event of safety valves coming into operation and releasing refrigerant gas, persons in the vicinity can be

injured or suffer toxic effects. Always wear suitable clothing and protective goggles when working in potential hazard areas.

In the event of refrigerant gas escaping, refer to the “Safety datasheet” for the particular refrigerant.

If an open flame or heat source is brought into contact with the refrigerant, or the pressurized gas circuit should overheat (e.g. during welding operations), this can cause explosion or fire. Do not position any heat source within the hazard area.

Maintenance or repair operations involving welding must be carried out with the system emptied of refrigerant.

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.

M03I40M7-03 15/11/07 page 11

POSITIONING

GENERAL

For installing air-conditioning systems, it is necessary to consider the following:

• the technical spaces necessary for the machine and

system

• the place where the machine will be installed

• the transport of thermal carrier fluids and relevant

connections to the unit:

o water o air o refrigerant (unit in more sections)

• electrical connections

If these aspects are not evaluated carefully, they can affect the performances and the working life of the unit.

FUNCTIONAL CLEARANCES

When placing the unit, please respect the functional clearances indicated in DIMENSIONS section. The functional spaces need to be observed because of the following:

• to guarantee the good operation of the unit

• to allow the performance of all maintenance operations

• to protect the authorized operators and exposed people

If more units are placed close to one another, the functional spaces must be doubled.

POSITIONING

1. The units are designed for INDOOR installations,

performed in fixed positions and in areas accessible only to qualified and authorized personnel

2. SAFETY VALVE (only if present on the unit) : the

installer is responsible for evaluating the opportunity of installing drain tubes, in conformity with the local regulations in force ( EN 378 )

3. Install the unit raised from the ground

4. avoid installations in places subject to flooding

5. Verify that the fixing/supporting points are level and

suitable to support the weight of the unit (see the weight and the weights distribution)

6. It is recommended to put the unit on specific

antivibration devices

Each support point of the unit sustains a different weight. Therefore, each anti-vibration device is sized for a specific support point, and can only be placed there. The anti-vibration devices must therefore be placed in accordance with the instructions provided with them and with the dimensional drawings in which the support points are indicated by W1 , W2 , W3 etc .

On each anti-vibration device (if provided by CLIVET), its identifying code is stamped, for example C6100100

Flexible joints are necessary on all the hydraulic/ aeraulic connections (the joints are not supplied by Clivet)

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.

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

10,5 bar evaporator 16 bar condenser

ARIES EFFECTS AND AIR BUBBLES CAN PRODUCE THE OVERCOMING AND CAUSE WATER DROPS.

EXCHANGER USE SIDE

FILTER

It is very important for the water to be free of impurities. If it is not, the efficiency of thermal exchange is diminished. In worst cases, the exchanger can be irreparably damaged. If the filter is not present on the machine, it must be immediately installed upstream from the unit, in a position which can be easily reached for cleaning.

The filter mesh must be :

• < 1 mm unit with 1 compressor

• < 1.5 mm multicompressor unit.

FLOW SWITCH

The flow switch must be present as a component of the system, so as to ensure shutdown of the unit if water is not circulating. It must be installed in a straight tract of the tubes, not near the elbows, which can generate harmful turbulence

UNFREEZABLE LIQUIDS

If the unit is used when the water temperature is lower than + 4°C, avoid the formation of ice by using unfreezable liquids (ex. Ethilenic Glycol) in the necessary percentage. The use must also be determined for ambient temperatures near 0°C .

ANTIFREEZE RESISTANCES

If the unit is equipped with antifreeze resistances on the exchanger side (standard or optional according to the models), verify that they are electrically fed during periods that the machine is stopped (night, weekends, long stops)

WASHING THE SYSTEM

Carefully wash the system by using clean water and discharge it before connecting the unit.

M03I40M7-03 15/11/07 page 15

DIAGRAM OF RECOMMENDED USE SIDE CONNECTION

Depending on the type of machine and the selected setup, some components may be integrated into the unit.

14. inertial storage tank

The accumulation tank is necessary in the event of the following:

• the water in the system is very low

• the unit will not be used in a private house (in an industrial process or other)

RECOVERY EXCHANGER

OPTIONAL - The unit can be equipped with exchangers to recover the condensation heat.

The recovery can be:

TOTAL

• with 100% recovery of the condensation heat

• the thermoregulation is performed by CLIVET control

system

PARTIAL

• with 20% recovery

• The customer is responsible for the management of the

circulation pump, valves, thermostats, etc

The recovery input water must not be below 25°C, in the event that, wrongful operations and breakages of the unit can occur .

Water connections must be performed carefully as for the evaporator (filter, circuit washing, etc) .

Perform all necessary interventions to avoid the RISK OF FREEZING (tubes insulation, emptying of circuit, addition of glycol, anti-freeze resistances) .

Water temperature can reach high temperatures (up to 100°C), therefore:

• avoid the RISK OF BURNS by adopting the necessary

precautions (insulation of tubes, temperature detecting station on water if the sanitary use is foreseen, etc)

• Install safety valves and specifically dimensioned expansion tanks in the hydraulic circuit.

VICTAULIC CONNECTIONS

1. Take away the supplied connection union by acting on the connection joint Victaulic.

2. Weld the union to the installation pipe.

3. Perform the connection between the installation pipe and the evaporator, using the joint.

Do not weld the system pipe with the Victaulic connection joint attached.

The rubber gasket might be irreparably damaged

SYSTEM MEASURES ON SOURCE SIDE

FILTER

It is very important for the water to be free of impurities. If it is not, the efficiency of thermal exchange is diminished. In the worst cases, the exchanger can be irreparably damaged. The filter, if not present on-board the machine, must be installed immediately upstream from the unit, in a position that is easily accessible for cleaning

FLOW SWITCH

Since it is a system component, it must always be included, in order to ensure unit shutdown in the event of failure of water circulation. It is to be installed in a straight section of the pipes, and not near curves which generate harmful turbulence.

ANTI-FREEZE SOLUTIONS

For use of the unit with ambient temperatures near 0°C, use antifreeze solutions such as ethylene glycol to prevent the formation of ice. Its use is also required when geothermal probes are used.

SYSTEM WASHING

Before connecting the unit, carefully wash the system by filling it and emptying it several times with clean water.

CONTROL OF FLOW RATE

This makes it possible to limit water consumption, increase energy efficiency and extend the unit's operating limits. It can be modified by using

1. Modulating motorized valve

2. Cut-off valve

3. Pressure switch valve

CUT-OFF VALVE

This allows cut-off of water on the source side whenever the compressor is not running.

It is therefore advisable for systems with disposable water, if there is no modulating valve

Few inputs must be activated by configuration parameters whose access is reserved to authorized assistance centers (in order to avoid unauthorized modifications)

ON / OFF FROM REMOTE CONTROL It allows the remote start and stop, not by keypad. It can be used to disable the unit during the night, the weekend etc., so with ON or OFF periods relatively longs (some hours). It has not to be used with ON or OFF cycles too much shorts: they compromise the operating logic and they can cause malfunctions or faults. In summer operating, for example, ON –OFF cycles lower than one hour can compromise the thermoregulation logic, that implements an integral check. If this function is not used, jump the respective terminals .

SIGNALIZATION OF MALFUNCTIONING/ UNIT FUNCTIONING Remote signalization of the proper function (ex. green light) or signalization of blocks of the machine (ex. red light). Maximum voltage at the terminal ends is 24v ac and maximum power is 1A

SECOND SET-POINT It allows the use of a secondary set-point, such as, for example, for a night operation, which can be activated by a remote contact. When the contact is CLOSED, the secondary set-point is activated .

DEMAND LIMIT It allows one to temporarily limit the electric power absorbed by the unit, according to a 10 vcc or 4-20 mA external signal. The higher the signal is, the lower the number of compressors available to meet the thermal need. The parameters must be configured by the assistance center .

START-UP

ALL THE EQUIPMENT MUST BE COMMISSIONED BY AUTHORISED SERVICE CENTRES.

THIS SERVICE IS LIMITED TO START-UP OF THE UNIT ONLY AND NOT THE CONNECTIONS OR INSTALLATION OF

THE SYSTEM.

ONLY QUALIFIED TECHNICIANS MUST PERFORM THE FOLLOWING OPERATIONS.

PRELIMINARY CHECKS

Before checking, please verify the following

1. the unit should be installed properly and in conformity with this manual.

2. the electrical power supply line should be sectioned at the beginning.

3. the sectioning device is locked and the proper warning “not to operate” sign is placed on the handle.

4. make sure no tension is present

REFRIGERANT SYSTEM

Carefully check the refrigerating circuit: the presence of oil stains can mean leakage caused by transportation, movements or other).

Open the cocks of the refrigerator circuit, if there are any.

Using the unit manometers, if present, or service manometers, verify that the refrigerating circuit is in pressure.

Make sure that all the service outlets are closed with proper caps; if caps are not present a leak of refrigerant can be possible.

WATER SYSTEM

Ensure that the plumbing system has been washed. Drain the wash water before connecting the unit to the system.

Check that the water circuit has been filled and pressurised.

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.

% weight of ethylene glycol

10 % 20 % 30 % 40 %

Freezing point

- 4 °C - 9 °C - 15 °C - 23 °C

Safety temperature

- 2 °C - 7 °C - 13 °C - 21 °C

Check that the circulator pumps are not blocked. In fact, their motor shaft may seize up, especially after long shutdowns. Unblocking can be accomplished with a screwdriver using the purge hole.

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 +/- 6% single phase unit; 400/3/50 +/- 6% 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.

IF THE CRANKCASE RESISTANCES ARE FITTED

when the unit is started up for the first time and following all prolonged periods of inactivity is OBLIGATORY to connect the oil resistances on the compressor crankcase at least 8 hours before the compressor is to be starter.

BEFORE POWERING THE RESISTANCES, OPEN THE COMPRESSORS COCKS, IF PRESENT.

To supply the resistances is necessary to switch off the isolator switch on the unit.

To make sure that hte resistances are working, check the power input with amperometic pliers.

At start-up the compressor cranckase temperature on the lower side must be higher at least of 10°C than the outside temperature.

DO NOT START THE COMPRESSOR WITH THE CRANKCASE OIL BELOW OPERATING TEMPERATURE.

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

M03I40M7-03 15/11/07 page 26

EVAPORATOR WATER FLOW RATE

Check that the difference between the temperature of exchanger return and supply water corresponds to power according to this formula:

unit cooling power (kW) x 860 = Dt (°C) x flow rate (L/h).

The cooling power is shown in the TABLE ON GENERAL TECHNICAL DATA included in this manual, referred to specific air/water conditions, or in the tables on cooling PERFORMANCE IN THE TECHNICAL BULLETIN referred to various conditions of use.

Check for water side exchanger pressure drops:

• Determine the water flow rate.

• Measure the difference in pressure between

exchanger input and output and compare it with the graph on WATER SIDE EXCHANGER PRESSURE DROPS.

The measurement of pressure will be easier if pressure gauges are installed as indicated in the DIAGRAM OF SUGGESTED WATER CONNECTIONS .

CONDENSER WATER FLOW RATE

Check that the difference between the temperature of exchanger return and supply water corresponds to power according to this formula:

unit cooling power + power absorbed by compressors (kW) x 860 = Dt (°C) x flow rate (L/h).

The data is shown in the table on GENERAL TECHNICAL DATA included in this manual, referred to specific air/water conditions, or in the tables on COOLING PERFORMANCE

in the TECHNICAL BULLETIN referred to various conditions of use.

Check for water side exchanger pressure drops:

• Determine the water flow rate.

• Measure the difference in pressure between

exchanger input and output and compare it with the graph on WATER SIDE EXCHANGER PRESSURE

DROPS. The measurement of pressure will be easier if pressure gauges are installed as indicated in the DIAGRAM OF SUGGESTED WATER CONNECTIONS.

REFRIGERANT CIRCUIT PARAMETER CHECK

Detecting the operational conditions is useful to control the unit along time: the performed records must be kept and be available during maintenance interventions.

When the unit works in stable conditions and according to the operating limits, take note of the following data:

1. compressor diacharge temperature (WARNING – BURN DANGERI)

2. condensing pressure

3. liquid temperature

4. dehydrator filter upstream and downstream temperature

5. return pressure

6. return temperature

7. exchanger input water temperature

8. exchanger output water temperature

UNIT START-UP

To turn the unit on or off, hold the ON/OFF switch down for a few seconds. When the unit is on, the “ON” message is displayed; when the unit is off, the “OFF” message is displayed.

It is also possible to access the different menus when the unit is in the “OFF” mode.

It is possible to check the ON/OFF condition at a distance, using a remote device (see the ELECTRICAL CONNECTIONS chapter).

CHARACTERISTICS

THERMOREGULATION

The thermal regulation is based on the INLET temperature. The unit is set for a specific TOTAL DIFFERENCE between the inlet and outlet water temperatures. Usually the designed difference is 5°C, in the event that a different value is foreseen, the 17 and 18 parameters must be set again by the assistance center. According to the total difference, the system defines the level of difference that each compressor can give : the STEP DIFFERENCE. The regulations tend to gradually insert the compressors when the inlet temperature is over the set-point + the step difference. The compressors are activated one per time at the end of the SCANNING TIME. This time varies according to the gap between the water inlet temperature and the Set-point value. The higher the gap value is (both negative and positive), the shorter the interval among the scanning points will be. The value of the scanning time is displayed at the status 6; when the status 7 has reached the value of the status 6, the request of operation of the compressor is activated. The counting of the scanning time starts together with the activation of the compressor. The compressor to be activated is chosen to make the shut circuits operate in order to minimize the wear of the entire refrigerating circuit, as well as the single compressor. At the end of the counting, if the inlet temperature is higher than the step difference, another compressor is inserted. temp. H2O > set-point + step difference. What above described is referred to the COOLING operating, in HEATING the logici s the same but overturned (compressor insertion for outlet temp. < set-point – step jump).

SET-POINT COMPENSATIONS

The compensations are evolved functions that aim at protecting the compressors and fit as much as possible, the operation of the unit to the characteristics of the system and its use. The compensations make the time of the compressors’ operation longer and limit the number of starts-up, to make them delay the insertion time by adding an offset.

• The compensation on the DURATION is useful when the water contained in the system is limited.

• The compensation on the CHARGE is useful when a variable charge is present.

Optional components are necessary; the modifications of the parameters performed by the assistance centers have to be performed to enable and configure. In industrial applications, where a precise control of the temperature is necessary, it is possible to deactivate the COMPENSATIONS. The Status menu displays the value of the compensations on ext. temp. (status

9) and WR (status 10).

M03I40M7-03 15/11/07 page 28

SET-POINT CORRECTIONS

The correction aim at optimising the energetic efficiency of the unit. To do this, the corrections dynamically modify the set-point according to some variables. For example, in the summertime with very low external temperatures, therefore with a reduced load, it is possible to obtain the internal comfort even with set-points higher that the standard with a consequent higher energetic efficiency. The static set-point can therefore be modified dynamically with two CORRECTIONS based on two factors external to the unit:

• Correction based on the External temp. / enthalpy

• Correction based on the Water reset (4-20 mA signal supplied by the Customer)

The correct set-point, to which all corrections have been added or detracted, is called PRESENT set-point and is visible at status 2. For further details, see the ELECTRICAL CONNECTIONS chapter.

MAINTENANCE SET POINT

It can be used to maintain the installation inside the working limits, even if the unit is deactivated. The MAINTENANCE Set Point checks the water temperature when the unit is put on OFF or Stand-by. To do this, it periodically activates the circulation pump, tests the water temperature and even activates one or more compressors. It is necessary to modify the parameters with access reserved to the assistance centres

MENU NUM Parameter name meaning

25 MantCoolEn It enables Summer Maintenance PARAMETER CONTROL MAINTENANCE

114 SetMantCool Summer maintenance set-point

DEMAND LIMIT

The function of the DEMAND LIMIT allows the limit of power so that the electric consumptions can be controlled by a signal external to the unit supplied by the customer. On the STATUS menu, no. 22, the external signal of DEMAND LIMIT is displayed. For further information,see the ELECTRICAL CONNECTIONS chapter.

SECOND SET-POINT

The secondary set point is activated by remote authorization (see the ELECTRICAL CONNECTIONS chapter). It is possible to limit the minimum power which can be delivered during the time in which the secondary set point is activated by configuring the 276 MinPot2Set parameter (access reserved to the assistance centres).

TIME TABLES

The system is factory equipped with a clock function, found on the board. By activating the timetables, it is possible to set up to 6 events for each day of the week. If there is also a remote keyboard, the operations relative to the time and the date must be repeated on both keyboards, so that the two clocks (which are different) are synchronized.

ALARMS

BEFORE RESETTING THE ALARM, IDENTIFY AND ELIMINATE THE CAUSE OF ITS ACTIVATION.

REPEATED RESETS CAN CAUSE IRREVERSIBLE DAMAGES.

The presence of an alarm is signaled by the icon flashing

. The cumulative block relay activates simultaneously, according to the type of alarm. Alarms can be reset once the conditions that caused them to trip have been removed. ALARMS and faults show a potentially dangerous situation for the machine integrity. An immediate analysis is necessary to detect the causes of the block. A repeated reset can provoke irreversible damage. That is why reset is MANUAL.

PRE-ALARMS AND SIGNALIZATIONS show a situation similar to that one described above. The occurrence of an alarm is acceptable if it is occasional and/or in transitory situations (for example, when the plant starts). In uncertain cases, please contact the authorized assistance center.

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.

SERVICES

Parts subject to intervention:

•

WATER EXCHANGER • STRUCTURE

WATER EXCHANGER

It is very important for the exchanger to be able to provide the maximum thermal exchange. Therefore, it is essential for the inner surfaces to be clean of dirt and incrustations.

Periodically check the difference between the temperature of the supply water and the condensation temperature. If the difference is greater than 8°C–10°C it is advisable to clean the exchanger.

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.

M03I40M7-03 15/11/07 page 38

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. 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)

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.

97/23 CE PED DIRECTIVE

97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well. Refer to local actuation norms. In Italy, refer to the Ministerial Decree of 1

December 2004 no. 329 (and following modifications) which defines the performances to be executed; the units of

category and those defined by the art. 3.3 97/23/EC are not included in this regulation (see the serial number plate on the unit) .

Briefly and as an example, see the following :

1. COMPULSORY VERIFICATION OF THE FIRST INSTALLATION only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)

2. CERTIFICATION OF SETTING IN SERVICE for all the units

3. PERIODICAL VERIFICATIONS to be executed with the frequency indicated by the Manufacturer (see the MAINTENANCE INSPECTIONS paragraph)

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.

REFRIGERANT TABLES

THIS SECTION IS DEVOTED ONLY TO QUALIFIED TECHNICIANS THAT KNOW THE FOLLOWING:

• THE OPERATIONAL PRINCIPLES OF THE REFRIGERATING CIRCUIT OPERATION

• THE MODES OF DETECTING TEMPERATURE AND PRESSURE

• THE RISKS RELEVANT TO THESE OPERATIONS

The data of the tables allow the testing of the refrigerating circuit operation by the detection of a few objective parameters. The data are significant if they are detected simultaneously and while the refrigerating circuit is running.

• Liquid temperature

• Return pressure

• Return temperature

• Condensing pressure

* It is important that the condensation pressure is detected as close as possible to the point where the liquid temperature is detected, in the event that the calculation will be effected by the losses of charge (and, therefore, of temperature) caused by the refrigerating circuit components placed between the two measurement points.

For R410A the glide was not considered, since it is close to 0.

The values in the tables refer to a specific refrigerant supplier; slight differences are possible with other suppliers.

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.

Below is a list of the possible causes of alarms.

HIGH PRESSURE (in cooling)

1. high water temperature (see operating limits)

2. insufficient water flow to the exchanger (high

thermal difference between input and output)

3. not CONSTANT flow (for example, if the pumps

are turned off, certain areas of the plant are excluded or included, other uses are isolated, etc )

4. Dirt water filter / valves open /air bubbles in the

plant

5. dirty exchanger

6. Manostat/transducer: loose electric

contacts/terminals, wiring cables interrupted

7. condensation gas in the cooling circuit

8. Too much refrigerant

9. Check the trigger point for the manostat and

transducer

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
