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.
pag 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.

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.

CONDENSATE DISCHARGE CONNECTION
.
1. The condensate must be dispersed to avoid damages to persons and property.
2. 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
3. Make a trap that, eliminating the depression caused by the fan, stops the return of gas from the discharge pipe (see the figure).
4. 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.
5. Finally, check that the condensate will drain correctly by pouring water into the tray stud.
6. RISK OF FREEZE : If the unit operates in cooling with external temperatures lower than 0°C, value the possibility that the condensate can freeze blocking the downflow and provoking flooding. Use heat cables or other devices to guarantee the disposal.
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.

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
5. the coils must be clean and free of obstacles
6. the ventilators must be free of leaves, cardboard, fixed obstacles (beams, barriers, etc.), snow, etc
7. the external ventilators must not be blocked
The external ventilators can be subject to a temporary block, especially if the inactivity period before the first start-up was quite long or if external temperature is very low. It is also possible to unblock them manually (ONLY WHEN THE UNIT IS UNPLUGGED – RISK OF INJURES) so that jams or electric overloads are avoided when the unit is restarted.
AERAULIC SYSTEM
Check that:
1. the air filters are not removed from unit and are cleaned (possible ventilation checks and the operating starting period determinate a ducting “cleaning” with conseguent filter precocius clogging, filters that must be cleaned and replaced)
2. ducting are completed, connected and without obstructions
3. possible dampers are opened (for ex. fire stop dampers) and calibrated (for ex. external air damper, control damper, ejection damper)
4. Grilles, outlets, and diffusers must be free of obstructions (furniture, shelves, etc.), open and pre­calibrated, so as to ensure proper air distribution, which is essential to comfort in the room.
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
Freezing point
Safety temperature
10 % 20 % 30 % 40 %
- 4 °C - 9 °C - 15 °C - 23 °C
- 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 HEATERS 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 heaters on the compressor crankcase at least 8 hours before the compressor is to be starter.
BEFORE POWERING THE HEATERS, OPEN THE COMPRESSORS COCKS, IF PRESENT.
To supply the heaters is necessary to switch off the isolator switch on the unit.
To make sure that hte heaters 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 external 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
UNIT EQUIPPED WITH SCROLL COMPRESSORS
The GENERAL TECHNICAL DATA table shows the type of compressor on the unit.
The Scroll compressors have only one direction of rotation.
In the event that the direction is reversed, the compressor will not be damaged, but its noisiness will increase and pumping will be negatively affected. After a few minutes, the compressor will stop because of the activation of the thermal protection. In this event, cut the power and reverse the 2 phases on the machine power.
Prevent the compressor from working with in reverse rotation: more than 2-3 anomalous starts up can damage it.
Make sure the direction of rotation is correct, measure the condensation and suction pressure. Pressure must clearly differ: at the start, the suction pressure decreases whilst the condensation pressure increases.
The phase optional monitor, which controls the phase sequence, can be installed later.
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) .

In the time the working point can change, for example for the operations on the system (grilles covered by furniture, closed outlets to modify the air diffusion, exclusion or addition of the distribution sections etc.) or for lacking maintenance (clogged air filters, blocked dampers etc) .
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

CLEAN
In the CLEAN mode, the unit is on the ejection mode with injection of all the external air for a fixed time; after this time, the mode deactivates. It can be activated from the thermostat, keyboard or remote selector (see ELECTRICAL CONNECTIONS section).
VENTILATION
When the unit is in ONLY VENTILATION mode, it operates like a fan; the fans are activated; no adjustment on the room temperature. It can be activated from the thermostat, keyboard or remote selector.
SET-POINT
MANUAL AMBIENT SET POINT
The room set point is defined by thermostat with parameter P01 ManSet = 23°C. The set is modifiable MANUALLY, the modify is limited in values: 25°C > ManSet > 21°C
25 °C = ManSet MAX
2°C = + P 09
23 °C = ManSet
2°C = - P 09
21 °C = ManSet MIN
Starting from ManSet the module calculates the set point for HEATING and COLING, spacing them of 1°C respect the manual set: COOLING = 24°C HEATING = 22°C
AUTOMATIC AMBIENT SET POINT
The set-point can also be adjusted AUTOMATICALLY to the external temperature variations: the variation curve is defined by 5 points, modifiable by service centers through the service keypad.

ALARM LIST
BEFORE RESETTING AN ALARM, IDENTIFY AND REMOVE ITS CAUSE.
REPEATED RESETS CAN CAUSE IRREVERSIBLE DAMAGE.
The ALARMS indicate a potentially hazardous situation for the machine integrity. Before resetting the alarm, identify and remove the reason of the lock: a repeated reset can cause irreversible damage. That's why the reset is MANUAL, namely through keyboard (provided that the cause no longer exists).
PRE-ALARMS and SIGNALS indicate a close risk situation. Their occurrence can be accepted if occasional and/or in temporary situations (for example at the system start-up). The reset is AUTOMATIC, that is there is a self-reset as soon as the cause ceases without any keyboard intervention.
FAILURES signal the malfunctioning of probes and transducers; they are AUTOMATICALLY reset, so that anyway the unit can operate, even if possibly with reduced functions.
In case of doubt contact an authorized service center. The presence of one or more alarms is signalled by the ALARM CODE blinking and by the machine time it/they occurred. The cumulative lock relay activates simultaneously with the alarm code displaying.
Some alarms, typically PRE-ALARMS, do not activate the relay. The table shows all the variables which can be managed by the electronic system.
According to the machine configuration and the accessories, some alarms can be not relevant.

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
SERVICES
Parts subject to intervention:
• EXTERNAL AIR COIL
• ROOM AIR TREATMENT COIL
• FILTERS
• STRUCTURE
• CONDENSATE DISCHARGE
EXTERNAL AIR COIL
ATTENTION: contact with the exchanger fins can cause cuts. Wear protective gloves to perform the above described operations. It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleaned from dust and deposits. Remove all impurities from the surface. Using an air pressure gun, clean the aluminum surface of the battery. Be careful to direct the air in the opposite direction of the fan air movement. Hold the gun parallel to the fins to avoid damages. As an alternative, an aspirator can be used to suck impurities from the air input side. Verify that the aluminum fins are not bent or damaged. In the event of damages, contact the authorized assistance center and get the battery “ironed out” in order to restore the initial condition for an optimal air flow.
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.
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.

• DUCTING
• STEAM HUMIDIFIER AND IMMERSED
ELECTRODES
• ELECTRIC ELEMENTS
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 micro­organisms and moulds most easily flourish. It is therefore very important to clean regularly with suitable detergents and disinfect with appropriate products as necessary.
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.

Materials required for maintenance:
1. Alkaline detergent A01212 (code CLIVET C6460315)
2. Acid detergent B01212 (code CLIVET C6460316)
3. Protective gloves and goggles
4. Graduated beaker
5. Manual or pneumatic pump for spraying
3
2
Pour part of the alkaline detergent into the graduated cylinder
Dilute with one part water so as to form a 50% solution
4
Fill the spray pump with the prepared solution
5
Also spray the detergent on the base of the contacts. Let the detergent stand for 2-3 minutes
7
Position the filter to be washed on a support so you can work comfortably. Spray the detergent on the blades of the electrostatic filter
6
Rinse with a jet of water or with a pressurized water cleaner at low pressure
8
Thoroughly rinse the insulators of the electrostatic cell Turn the filter and rinse the back as well
pag 29
After washing with alkaline detergent, this is how the filter should look. Otherwise repeat steps 4 to 7
9
Prepare a tub with a 1/20 solution of detergent B01212 diluted in water. Immerge the filter you have just washed in this solution to eliminate alkaline detergent residue. Make sure that the solution covers the entire filter Do not use aluminium or galvanized sheet metal tubs.
11
10
Within 2-3 minutes you will note a slight chemical reaction with the formation of foam. This indicates that the alkaline residues have been eliminated
12
Rinse the filter again with a jet of water or with a pressurized water cleaner at low pressure
IONIZATION WIRES
Impurities may cause oxidation or encrustation on the wires. These may be removed using a cloth soaked in alcohol or with very fine grain steel wool. Because of the high voltage that powers them, the ionization wires are subject to wear. Yearly replacement will prevent unexpected breakage. If breakage occurs:
1. Remove all pieces of wire in the cell and remove the spring that holds the wires taut.
2. Hook the spring onto the eyelet of the wire.
3. Grasp the ionization wire with a curved pincer.
4. Hook the end of the spring with the open eyelet to the wire-tensioning rod of the electro-static cell
5. Holding the ionization wire taut with the other hand, hook it onto the other wire-tensioning rod, again using a curved pincer
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.
CONDENSATE DISCHARGE
Dust and deposits could cause obstructions. Clean the tank, pour some water into the tank and check water flows normally.
Dry the electrostatic cells in a warm room or in direct sunlight for a few hours. Keep the cells up off the ground with two pieces of wood or metal.
pag 30
DUCTING
Check the fixing screws and the operation of the anti-vibration devices in order to prevent the transmission of vibrations in the room.
ELECTRIC FANS
Make sure that the fans and the relative protection grids are well fixed. Check, if possible, the unbalances of the electro-fan evident by noise and anomalous vibrations. Verify that the terminal protection covers are closed and the cable holders are properly positioned.
STEAM HUMIDIFIER AND IMMERSED ELECTRODES
The humidifier and the cylinder contain live electrical components and hot surfaces. All maintenance operations must be performed by qualified, experienced personnel who have been trained on possible hazards. During operation, the steam production cylinder reaches high temperatures! Maintenance must be performed after the cylinder has cooled. Use protective gloves. The cylinder must be replaced periodically. This operation is necessary when lime incrustations build up on the inside such that sufficient current passage does not occur. How frequently this needs to be done depends on the water supply. The harder the water, the more often the cylinder will need to be replaced. The water supply must not be softened. This causes corrosion of the electrodes, foaming and possible abnormal operation. After prolonged use or use with very hard water, the solid deposits on the electrodes may increase in size until they adhere to the inner wall of the cylinder. With especially conductive deposits, the plastic may heat so much that it melts, resulting in water leakage. In case of leaks, power off the unit before touching the cylinder, because electrical current may be flowing through the water.

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
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; briefly and as an example, see the following :
• COMPULSORY VERIFICATION OF THE FIRST INSTALLATION only for units assembled on the installer’s building site
(for ex. Condensing circuit + direct expansion unit)
• CERTIFICATION OF SETTING IN SERVICE for all the units
• PERIODICAL VERIFICATIONS to be executed with the frequency indicated by the Manufacturer (see the
MAINTENANCE INSPECTIONS 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 heaters if present
• 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.
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.
