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 UNITto 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 80mm. (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 thelowest 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). l. 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 outsideAfter 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 – 11UNICO PRO INVERTER

ENGLISH

2.4 – UNIT ASSEMBLYThe maximum allowed length of the pipes is 1 m, the pipes must be internally smooth, with a diameter 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. · 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 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 (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.EN – 12

ENGLISH

· Drill the holes, previously marked, for the wall plugs related to the fixing brackets (fig. 6).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) which can be accessed after opening the door (6) under the unit (fig. 7 ) must be connected to the air conditioner. 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 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.EN – 13UNICO PRO INVERTER

ENGLISH

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 (fig. 11) inside them. Since the sheet (G) was made for 202 mm holes, you will have to cut off 130 mm from the long side of the sheet for the 162 mm holes (fig. 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. (fig.12). Use an ordinary cutter for the foregoing operation (fig. 12).to position the external grids, proceed as follows: a. Apply the seal (F) to the wall flange (D), ensuring it lines up with the outer edge of the flange as indicatedin the figure 13. b. Fix the two flanges using 2 pegs having a diameter of 6 mm and check that the two fixing holes arehorizontal (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 untilit 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 fingersinside 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. l. Pull the chain, tensioning the spring, and couple the chain ring to the pin of the inner flange throughwhich the pipes pass (fig. 20). m. Use hand shears to cut off any excess chain links.Use exclusively the supplied grids (E), or grids with like characteristics.2.4.4 – Preparing the holes on the machineif Ø 200 mm holes are being used, work as follows: a. if 162 mm pipes are being used, the removal operation of part of the rear cover must not be performed.The fan extension cable (W) (fig. 21) must be removed. b. Use pliers to break the preblanking of the rear cover (fig. 22-A). c. then, rotate the cover part to be removed back and forth with your hand until you break the remainingpreblanked part (fig. 22-B). d. Trim excessive insulating material remained inside the hole using an utility knife (fig. 22-B).the rear cover is also suitable for a rectangular suction channel. If you prefer this type of installation, break the rectangular preblanking shown in fig. 23 and use a suction grille of a size suitable for the suction channel.2.4.5 – Positioning of the device on the anchor bracketsWorking on the two previously drilled holes (see fig. 6), fix the support brackets (L) to the wall using the supplied wall plugs screws (H) (fig. 24).after checking …….EN – 14
