- Before starting to operate on the appliance, it is necessary to check the zone surrounding the equipment to make sure there are no dangers of fire risks of combustion.

This product must be used exclusively according to the specifications indicated in this manual. Use different to that specified, could cause serious injuries.

THE MANUFACTURER IS NOT LIABLE FOR INJURY/DAMAGE TO PERSONS/OBJECTS DERIVING FROM FAILURE TO COMPLY WITH THE REGULATIONS CONTAINED IN THIS MANUAL.

To repair the refrigerating system, it is necessary to take the following precautions before starting the intervention on the system.

1. It is necessary to define the area around the work space and to avoid working in tight spaces. Ensure safe work conditions by checking flammable material.

EN - 7

1. All personnel in charge of maintenance and people which work in the surrounding area must be instructed on the type work they are going to carry out.

1. The zone MUST be checked with a specific refrigerating liquids detector before and during work, so that the technician is aware of potentially flammable atmospheres. Make sure the detection device of the leaks is suitable for use with flammable refrigerants, then that it does not produce sparks and that is adequately sealed or intrinsically safe.

2. The leaks electronic detectors may need calibration. If necessary, calibrate them in a zone free of refrigerant.

3. Make sure the detector is not a potential source of combustion and that it is suitable for the refrigerant used. The device for detection must be set at a percentage of the refrigerant LFL and must be calibrated for the used refrigerant; the appropriate percentage of gas (maximum 25 %) must be confirmed.
4. If the presence of a leak is suspected, all open flames must be removed. If a fluid leak which requires brazing is encountered, all refrigerant must be collected from the system or insulated (by means of shut off valves) in a part of the system away from the leak. Then, bleed nitrogen without oxygen (OFN) through the system both before and after the brazing process.

1. In case it is necessary to carry out a hot work on the appliance, IT IS NECESSARY to have a powder or CO_2 fire extinguisher available.

1. To carry out a work which includes exposition of pipes which contain or contained a flammable refrigerant, DO NOT use sources of combustion. sk of fire or explosion!

2. All sources of combustion (even a lit cigarette) should be kept away from the place in which all operations during which the flammable refrigerant may be released in the surrounding space must be carried out.

3. Make sure the area is adequately ventilated before intervening inside the system; a continuous degree of ventilation must be present.

1. DO NOT use means different from those recommended by the manufacturer in order to speed up the defrosting process or for cleaning.

2. Before any operation, always check that:

• the condensers are unloaded.
The operation must be carried out safely to avoid the risk of producing sparks;
- there are no live electrical components and that the cables are not exposed while loading, recovering or bleeding the system;
• there is continuity in the ground connection.

EN - 8

1. All electrical power supplies must be disconnected from the appliance on which you are working.

If it is absolutely necessary that the appliance has electrical power supply, it is necessary to place a leak detector permanently operational in the most critical point.

1. Make sure the seals and sealing materials have not deteriorated. Possible development of flammable atmospheres.

1. Do not apply any net inductive or capacity load to the circuit without making sure that this operation won't make you exceed the voltage and current permitted for the appliance in use.

The appliance for the test must have correct nominal values.

1. Periodically check that the cables are not subject to wear, corrosion, excessive pressure, vibrations, sharp edges or any other hostile environmental situation.

2. When intervening inside the refrigerating circuit to carry out repairs or for any other reason, the conventional procedures must be followed:

3. remove the refrigerant;

4. bleed the circuit with an inert gas;
5. evacuate;
6. bleed again with an inert gas;

7. open the circuit by cutting or by means of brazing.

8. The load of refrigerant must be stored in the specific custody cylinders.

The system must “cleaned” with OFN to make the unit safe.

It may be necessary to repeat this process several times.

DO NOT use compressed air or oxygen for this operation.

1. The cylinders must be kept in vertical position.

Only use cylinders suitable for collection of refrigerants.

The cylinders must be complete of a pressure-relief valve and switch off valves in good conditions.

A set of calibrated weighing scales must also be available.

1. The pipes must be equipped with couplings for disconnection and must NOT present leaks.

Before using the collection machine, check that it underwent correct maintenance and that the possible associated electric components are sealed, to prevent switching on in case of leak of refrigerant.

1. Make sure the refrigerating system is earthed before proceeding with reloading of the system with refrigerant.

Label the system when reloading is complete.

Pay particular attention not to overload the refrigerating system.

1. Before proceeding with reloading, the system must undergo the pressure test with OFN and the tightness test at the end of reloading, but before commissioning.
   It is necessary to carry out an additional tightness test before leaving the site.
2. Collected refrigerant must be returned to the fluid supplier in the appropriate collection cylinder, compiling the corresponding Transfer Note of Scraps. DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.
3. If the compressors or their oils must be removed, make sure they have been emptied at an acceptable level to be sure that the flammable refrigerant does not remain in the lubricant.

This process must be carried out before the compressor returns to the suppliers.

Only use electric heating on the compressor body to speed up this process.

1. Once installation is complete, check that there's no loss of refrigerant (the refrigerating liquid produces toxic gas if exposed to a flame).

0.5 - PROPER USE

• The air-conditioner should be used for the exclusive purpose of producing hot or cool air (on demand) for the sole purpose of obtaining a comfortable temperature in the room.
• An improper use of the devices (external and internal) with possible damages caused to people, things or animals relieves OLIMPIA SPLENDID from any liability.

0.6 - HAZARDOUS ZONES

• The climate controllers must not be installed in environments with the presence of inflammable gases, explosive gases, in very humid environments (laundries, greenhouses, etc.), or in places with other machines that generate a strong heat source, in proximity of a sources of salt water or sulphurous water.
• DO NOT use gas, gasoline or other inflammable liquids near to the climate controller.

- The climate controller does not have a fan for the introduction of fresh outdoor air into the room; ventilate by opening doors and windows.

• Always install circuit breaker and a dedicated power circuit.

2.1 - INSTRUCTIONS FOR INSTALLATION

To obtain the best results and optimum performance, follow the instructions for correct installation provided in this manual.

A failure to implement the indicated standards, which may cause a malfunction of the appliances, relieves OLIMPIA SPLENDID from any form of warranty and from any liability for possible damages caused to people, animals or things.

The electrical system must be compliant with legal standards, must respect the data in the technical data sheet and be must be equipped with an efficient ground system.

EN - 12

2.2 - Size and specifications of the room in which to install the air conditioner

• Before installing the air conditioner, it is essential to make an accurate calculation of the heat load in summer (and cold load in winter for models with heating pump) at the site of installation.
  • The more accurate this calculation is made the better the air conditioner will be able to do its job.
• When executing the calculations, refer directly to the prevailing standards.
  • For particularly important applications, we recommend contacting expert heating engineers.
• The user should try to limit high heat loads as much as possible as follows: glass doors and windows exposed to many hours of sunlight should be fitted on the inside with curtains or, even better, on the outside with coverings such as Venetian blinds, verandahs, refractive film, etc.). The air-conditioned room must remain closed as long as possible.
• Halogen spotlights or other electrical equipment with high power consumption should not be used in the room (toasters, steam irons, hot plates for cooking, etc.).

2.3 - CHOOSING THE POSITION OF THE UNIT

To obtain the best operating performance and prevent faults or hazardous conditions, the position of indoor unit installation must meet the following requirements:

a. Do not expose the appliance to heat or steam sources (fig. 3).
b. Make sure that the space to the right and left is at least 60 mm and space above the unit is at least 80 mm. (fig. 2).
c. The height of the unit's lower edge from the floor should be at least 100 mm if fixed to the wall in the lowest position. If fixed to the wall in the highest position, it should be at least 80 mm from the ceiling (fig. 2).
d. The wall where the indoor unit is to be fixed, must be stable, strong and suitable to support the weight.
e. It must be possible to leave room around the unit for any maintenance operations that may be necessary.
f. Nothing should be in the way of the air that needs to circulate both on the top air-intake (curtains, plants, furniture) and at the front where the air exits. This could cause air swirls that would inhibit the working efficiency of the unit (fig. 3).
g. Do not spray water or other liquids of any kind directly on the unit (fig. 3).
h. The appliance must not be positioned so that the air flow is directed directly towards nearby people (fig. 3).
i. Never force the opening of the airflow flap (fig. 3).
I. Do not place bottles, cans, clothes, flowers or any other object on the air suction grille (fig. 3).
m. Do not install the air conditioner directly on another household appliance (TV, radio, fridge, etc.), or on a heat source (fig. 3).

The air conditioner must be installed on a wall that communicates with the outside

After determining the best place for installation as described above, check for the absence of other structures or systems (beams, piers, pipes, wires, etc.) at the points where the holes are to be drilled, which would prevent drilling the holes required to install the unit.

Check again to make sure there are no obstacles to air circulation through the holes to be drilled due to plants and their leaves, slats or panelling, blinds, gratings or grids too dense, etc.).

EN - 13

2.4 - UNIT ASSEMBLY

The maximum length allowed for the pipes is 1 m, the pipes must be internally smooth and no bends can be made.

It is necessary to use the grilles provided, or grilles which keep the same features.

2.4.1 - Drilling the wall

To operate, the unit requires two holes to be drilled in the wall, positioned as indicated on the drilling template; the holes must be 162 mm in diameter.

• It is possible to install the unit UNICO PRO INVERTER instead of a unit UNICO SKY or UNICO STAR or UNICO SMART or UNICO INVERTER without modifying the already existing holes, exception made for the small condensation drain hole.
  In this case, in order not to penalize performances, remove the insulating material possibly present in the air expulsion hole. The anchoring brackets need new drilling too.
• Drill the wall using the proper tools to facilitate your job and prevent excess damage or disturbance to your client.
  The best tools for drilling large holes in walls are special drills called core borers with very high twisting torque and adjustable rotating speed depending on the diameter of the hole to be drilled.
• To prevent the creation of large amounts of dust and rubble due to drilling, the core borer can be fitted with a vacuum system applied by means of suction cups to the drilling zone.
  • To drill the holes, proceed as follows:

- Place the supplied drill jig (M) against the wall observing the minimum distances from the ceiling, the floor and from the side walls indicated on the jig itself which can be kept in the correct position using adhesive tape (Y) (fig. 4).

- Use a small drill or punch to mark, with extreme care, the exact centre of each of the holes to be drilled (fig.4).

- Using a core boring head measuring 162 mm to drill the two holes for entry and exit of the air.

Drill the foregoing holes tilted slightly downwards to prevent water from being fed back through the ducts (fig. 5).

Most of the removed material is expelled outwards, therefore make sure that it does not hit any person or object when it falls out.

In order to avoid as much as possible outer plaster breaking, it is necessary to proceed carefully with the last part of hole execution, decreasing pressure on core borers.

- Drill the holes, previously marked, for the wall plugs related to the fixing brackets (fig. 6).

EN - 14

Carefully check the characteristics and consistency of the wall in order to possibly choose wall plugs specific for particular situations.

The manufacturer will not be held liable for any underestimates made in the structural consistency of the anchor prepared by the installer.

Therefore, pay utmost attention to the foregoing operation that could cause serious injury/damage to people/property if carried out incorrectly.

- When installing models equipped with heating pump, if no condensate discharge was built into the wall (see paragraph 2.4.2), in order to drain the condensate it will be necessary to drill a hole through the wall in the position shown on the template.

2.4.2 - Preparing the condensate discharge

- As regards machines with heat pump, a condensation drain pipe (fig. 1 - ref. N) (supplied) to be inserted in the specific connection (A) (fig. 7).

Remove the cap (B) (fig. 7) before inserting the condensation drain pipe.

When the max level is reached, a solenoid valve ensures the condensate will flow out from the internal tray.

• For cold-only machines, connect the condensate discharge pipe if you intend running the unit at low outdoor temperatures (lower than 23°C).
• Since condensate drains by gravity, there must be a minimum slope of at least 3% at every point of the discharge line. Use a rigid or flexible tube having an inside diameter of at least 16 mm.
• If the line empties into a sewerage system, install a siphon before the point in which the pipe reaches the main discharge, at least 300 mm below the inlet from the unit (fig. 8).
• If the drainpipe drains into a vessel (tank or other container), this container should not be sealed and the drainpipe should not remain immersed in the water (see fig. 9).
• The hole (J) through which the condensate pipe passes should always slope towards the outside (see fig. 10).

The exact position in which to place the pipe inlet, as compared to the machine, is shown on the drilling template.

Make sure, in this case, that the water expelled outward does not damage or disturb persons or property.

During the winter this type of drainage may cause sheets of ice to form.

When the condensate drainage is fitted, pay much attention not to compress the rubber hose.

In the event of operation during the winter with temperatures equal to or lower than 0^ C, make sure that the condensate drain pipe is protected from freezing in order to ensure draining.

In the event of prolonged operation during the winter with temperatures below 5^ C, install the optional basin heater kit.

2.4.3 - Assembly of the air ducts and external grids

• After drilling the holes (with the core drill), insert the plastic sheet (H) supplied with the air conditioner (fig. 11) inside them.

Cut a 130 mm flap on the long side from the sheet (H) (fig. 11).

The sheets must be 65 mm shorter than the length of the wall.

- Roll the sheet (H) and insert it into the hole, paying attention to the splicing line, which must always face upwards. (fig.11).

Use an ordinary cutter for the foregoing operation (fig. 11 - 12).

To position the external grids, proceed as follows:

a. Apply the seal (G) to the wall flange (D), ensuring it lines up with the outer edge of the flange as indicated in the figure 13.

b. Fix the two flanges using 2 pegs having a diameter of 6 mm and check that the two fixing holes are horizontal (fig. 14 - 15 - 16).

c. Fit the small eyelet of the spring, with the long stem, on the cap pin (on both components) (fig. 17).

d. Insert the two caps (with spring), on the front part of the external grid, on its two housings, pulling until it clicks (fig. 18) and couple the two chains to the large eyelet of the spring.

e. Using one hand, grip the two chains connected to the grid;

f. Bend the external grids back, gripping them with your free hand where they bend, and insert your fingers inside the single fins (fig. 19).

g. Insert your arm into the pipe until the grid protrudes completely outwards.

h. Reopen the grid, being careful to keep your fingers inside the fins.

i. Turn the grid until the fins are fully horizontal and tilted downwards.

I. Pull the chain, tensioning the spring, and couple the chain ring to the pin of the inner flange through which the pipes pass (fig. 20).

m. Use hand shears to cut off any excess chain links.

Use exclusively the supplied grids (F), or grids with like characteristics.

2.4.4 - Preparing the holes on the machine

The unit is designed exclusively for coupling with pipes for the exit and entry of air with a diameter of 162 mm.

2.4.5 - Positioning of the device on the anchor brackets

Working on the two previously drilled holes (see fig. 6), fix the support brackets (L) to the wall using the supplied wall plugs screws (E) (fig. 21).

After checking:

that the fixing brackets are well anchored to the wall,

that the installation site has been prepared for electrical connection and condensation discharge (if necessary),

it is possible to hook the air conditioner.

Work as follows:

a. Apply adhesive tape (A) to have references to the hooking points of the unit (fig. 22).

The tape can be removed once the unit has been hooked to the wall.

b. Raise the air conditioner holding it by the sides of the lower base and hook it to the brackets (L) (fig. 23).

Slightly tilt the lower part of the appliance towards yourself to ease the operation.

EN - 16

- To make the electrical connection and fasten the drainpipe, place a wedge between the air conditioner and the wall (see fig. 24).

- When you have finished, inspect carefully to make sure there are no fissures at the back of the air conditioner (the insulating gasket must fit firmly against the wall) particularly in the zone where air enters and leaves the machine.

3.1 - WARNINGS

The installation and electrical connection of the air conditioner should be carried out by specialized personnel who possess the requisites set forth by law.

The installation instructions are contained in the appropriate paragraph of this manual.

No structural object (furniture, curtains, plants, leaves, blinds, etc.) should ever obstruct the normal flow of air from either the internal or external gratings.

• Never lean or, worse yet, sit on the casing of the air conditioner as this could cause serious damage to the external parts.
• Do not move the air outlet flap by hand. Always use the remote control to adjust baffle position.
• If the unit leaks water, switch it off immediately and disconnect it from the power mains. Call the nearest service centre.
• When the air conditioner is heating, it has to periodically eliminate any ice that could form on the external battery. While it is doing this, the machine keeps running but does not heat the room. This lasts for a brief period of time, from 3 to a maximum of 10 minutes.
• Clean the air filter periodically, as described in the specific paragraph (4.1.2).

EN - 18

The air conditioner must not be installed in rooms where explosive gasses develop or where there are conditions of heat and humidity beyond the maximum limits indicated in the installation manual.

3.2 - DESCRIPTION OF THE WARNING PANEL

In the upper right part of the appliance are located a few keys and LEDs whose functions are described in the paragraph (4.3.3).

3.3 - USE OF THE REMOTE CONTROL

The remote control supplied with the air-conditioner is the instrument that enables you to use the appliance in the most convenient way.

It should be handled with care and in particular:

• Keep it dry (do not clean it with water or leave it outdoors in bad weather).
• Avoid dropping or bumping it.
• Keep it out of direct sunlight.

e. Put the filters back in their original position.

To deactivate the LED A (if on), after cleaning and repositioning the filters, electrically connect the appliance then press the reset key H briefly using a pointed object.

In this way, the signal relating to the need for filter cleaning is reset.

4.2 - MAINTENANCE

If you plan to idle the unit for a long time, perform the following:

a. Stop the air conditioner and disconnect the power supply.
b. Remove the batteries from the remote control.

Do not perform them alone.

4.2.1 - Routine maintenance

The air conditioner that you have purchased has been designed to reduce routine maintenance operations to a minimum.

These operations involve solely the cleaning operations outlined below:

• Cleaning or washing of the ambient air filter every 2 weeks or every time the relative red LED lights up (this can be done by the user, see user manual).
  • Cleaning of the condensing battery and cleaning of the condensate management system.

These operations must be carried out by skilled technicians on a regular basis that will depend on the place of installation and intensity of use.

Depending on the quantity of dirt, the unit can be cleaned dry (by using a battery compressor and bowl and cleaning the fins with a soft brush taking care not to deform them) or more thoroughly using dedicated detergents.

Before you leave the site of installation you should gather up all packing material and use a damp cloth to remove any traces of dust that may have deposited on the machine during assembly (fig. 24).

These operations, though certainly not essential, have a beneficial effect as they enhance the professional image of the installer in the eyes of the client.

To prevent unnecessary calls by the user, before you leave the site of installation

• it is also a good idea to:
- Explain the contents of the Instruction Manual to the user.
• Show the user how to clean the filter.

4.2.2 - Condensation water drainage in case of emergency

If anomalies occur in the condensation water disposal system, the air conditioner stops and signals the alarm status with the intermittent lighting up of LED A, LED B and LED C (fig.46).

To enable the air conditioner to work temporarily until the service personnel arrive, you can drain the water out by following these simple instructions (fig. 32):

Before proceeding with any maintenance and cleaning, always make sure the system has been switched off, using the remote control, and the power supply plug has been disconnected from the system socket (or the upstream master isolating switch is positioned at "0" OFF).

a. Remove the cap (6a) after having placed a good-sized container underneath it (at least 5-liter capacity) to collect the water.
b. After having cleared the fault, the service personnel will close the evacuation pipe.

4.3.1 - Diagnosis of the inconveniences

It is important for the User to distinguish between functional problems and anomalies in relation to the behaviour of the appliance as foreseen for its normal operation. Furthermore, the most common problems may easily be solved through simple operations on behalf of the User (See paragraph 4.3.5 - Anomalies and solutions).

For all the other reports (see paragraph: 4.3.3 - 4.3.4), it is necessary to always contact the technical assistance service"

Any attempt to repair the appliance by unauthorised personnel will immediately invalidate any form of guarantee.

4.3.2 - Functional aspects not to be mistaken for anomalies

The following events may occur during normal operation:

a. The compressor does not start up again immediately after a stop (it takes about three minutes to start again).

- In the operating logic of the appliance a delay between a compressor stop and its successive restart has been included, so that the compressor itself is protected against activations that are too frequent.

b. During the heating operation of the heat pump appliances, the flow of hot air may occur some minutes after activation of the compressor.

- Should the fan start at the same time as the compressor, for the first few minutes it would emit cold air into the room (and this could bother the occupants) since the unit has not yet reached steady running conditions.

4.3.3 - Console led signals

In the event that the air conditioner is blocked, the LEDs highlight an alarm signal as per table "TAB1". Contact an Olimpia service centre.
