• 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 exposedtomanyhoursofsunlightshouldbettedontheinsidewithcurtainsor,evenbetter,onthe outsidewithcoveringssuchasVenetianblinds,verandahs,refractivelm,etc.).Theair-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. Donotexposetheappliancetoheatorsteamsources(g.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.(g.2). c.

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, grat- ings or grids too dense, etc.).ENGLISH EN - 16

The maximum allowed length of the pipes is 1 m, the pipes must be internally smooth, with a di- ameter equal to 202 mm or 162 mm and bends cannot be performed. It is necessary to use the grilles provided, or grilles which keep the same features.

2.4.1 - Drilling the wall

Install the unit by drilling two holes (diameter of either 162 mm or 202 mm) in the wall as indicated in the drilling template. The 202-mm holes will ensure best performance and utmost noiselessness.

• 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.

• Topreventthecreationoflargeamountsofdustandrubbleduetodrilling,thecoreborercanbetted 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, theoorandfromthesidewallsindicatedonthejigitselfwhichcanbekeptinthecorrectposition usingadhesivetape(Y)(g.4). - Use a small drill or punch to mark, with extreme care, the exact centre of each of the holes to be drilled(g.4). - Using a core boring head measuring at least 202 mm (or 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 (g. 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.UNICO PRO INVERTER R32 ENGLISH EN - 17

• Drilltheholes,previouslymarked,forthewallplugsrelatedtothexingbrackets(g.6). Carefully check the characteristics and consistency of the wall in order to possibly choose wall plugs specic 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.

• 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 dischargeline.Usearigidorexibletubehavinganinsidediameterofatleast16mm.

• If the line empties into a sewerage system, install a siphon before the point in which the pipe reaches themaindischarge,atleast300mmbelowtheinletfromtheunit(g.8).

• If the drainpipe drains into a vessel (tank or other container), this container should not be sealed and thedrainpipeshouldnotremainimmersedinthewater(seeg.9).

• Theholethroughwhichthecondensatepipepassesshouldalwaysslopetowardstheoutside(seeg. 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 tted, 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.ENGLISH EN - 18

2.4.3 - Assembly of the air ducts and external grids

• After drilling the holes (with the core drill), insert the plastic sheet (G) supplied with the air conditioner (g.11)insidethem. Since the sheet (G) was made for 202 mm holes, you will have to cut off 130 mm from the long side of thesheetforthe162mmholes(g.11). The sheets must be 65 mm shorter than the length of the wall.

• Roll the sheet (G) and insert it into the hole, paying attention to the splicing line, which must always face upwards. (g.12). Useanordinarycutterfortheforegoingoperation(g.12). To position the external grids, proceed as follows: a. Applytheseal(F)tothewallange(D),ensuringitlinesupwiththeouteredgeoftheangeasindicated inthegure13. b.

When using the accessories B1014 and/or B1012, it is not possible to control the air conditioner neither from the remote control nor from the keys on the air conditioner console.MODE DisplayLED5LED1

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 ow 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 ap by hand. Always use the remote control to adjust bafe 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 lter periodically, as described in the specic paragraph (4.1.2). The air conditioner must not be installed in rooms where explosive gasses de- velop or where there are conditions of heat and humidity beyond the maximum limits indicated in the installation manual.

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.

• The remote control operates by means of an infrared beam.

• During use, there must not be any obstacle between the remote control and the air-conditioner.

• If other appliances in the room have remote controls (TV, stereo, etc...), there may be interference with consequent loss of the sent signal.

• Electronic and uorescent lights may also interfere with transmissions between remote control and air-conditioner.

• Remove the batteries in case of prolonged disuse of the remote control.

• The remote control display goes off after a few seconds of non-use, to reactivate it press any key.

• Reset as described in paragraph 3.2UNICO PRO INVERTER R32 ENGLISH EN - 25

3.4.1 - Insertion of batteries

Toinsertthebatteriescorrectly(gure35-36): a. Remove the batteries compartment cover. b. Insert the batteries into the relevant compartment. Check the polarity indicated on the bottom of the compartment (g.36). c. Closethecompartmentcorrectly(g.37).

3.4.2 - Replacement of batteries

The batteries should be replaced when the display on the remote control does not appear sharply or when the remote control does not change the settings. Always use new batteries and replace both at the same time. The use of old or different batteries could generate malfunctioning of the remote control. The remote control uses two dry alkaline 1.5V batteries (AAA.LR03). When the batteries have been replaced, adjust the remote control clock.

When replacing batteries, replace both and dispose of the dead batteries in the appropriate collection centres and as required by law.

• If the remote control is not used for several weeks or longer, remove the batteries. Any leaks from the batteries could damage the remote control.

• The average life-span of the batteries, with normal use, is approx. six months. Replace the batteries when the indoor unit command receipt “beep” can no longer be heard, or if the transmission indicator on the remote control does not switch on.

Do not re-charge or disassemble the batteries. Do not throw the batteries into the re. They can burn and explode.

If the battery liquid falls onto the skin or clothes, wash well with clean water. Do not use the remote control with batteries that have leaked. The chemical products contained in the batteries can cause burns or other risks to health.

3.4.3 - Location of the remote controller

• Keep the remote control in a position from which the signal can reach the appliance receiver (maximum distanceisabout8meters-withchargedbatteries)(g.38). The presence of obstacles (furniture, curtains, walls, etc.) between the remote control and the appliance reduces the remote control range.D

The remote control is the interface between the air-conditioner and the customer, so it is very important to learn all its functions, the use of the various controls and the meaning of the symbols marked on it.
