1.2.3 OVERVIEW OF INSTALLATION KEY: 1. Select the installation position (X = 15 cm, Y = 2,3 mt, Z = 12 cm) 2. Determine the position of the hole in the wall. 3. Secure the mounting plate 4. Drill the hole in the wall 5.
Page 16 1.2.4 INSTALLATION Before installing the indoor unit, see the label on the box of the product to make sure that the model number of the indoor unit matches the number of the Outdoor Unit. STEP 1: Choosing the place of installation. Before installing the indoor unit, choose a place for correct installation.

Page 18 Using a minimum 65mm size cutter bit for the drill (for UI Thor-24 it must be a minimum of 90mm), drill a hole in the wall, ensuring that it is angles slightly downwards, so that the outer end is about 5-7mm lower than the inner end. Indoor Outdoor KEY:...
Page 19 STEP 4: Preparation of cooling pipes The cooling pipes are located inside an insulated sleeve connected to the back of the indoor unit. The pipes must be prepared before threading them through the hole in the wall. 1. Based on the position of the hole in the wall for the mounting plate, choose the side from which the pipes will exit the unit. 2.
Page 20 STEP 5: Connection of drain pipe By default, the drain pipe is connected on the left side of the unit (in a front position with respect to the back of the unit). However it can also be connected on the right side. To guarantee adequate drainage, connect the drain pipe on the same side that the cooling pipes exit the unit.
Page 21 STEP 6: Signal and power supply cables connection The connection cable between the indoor and outdoor unit allows to power the indoor unit(s) and communication. The type of cable and relative dimensions to be used are indicated in the wiring diagram below. All electrical connections must be made strictly complying with the wiring diagram sticker applied on the inside of the front panel and checking the connection wiring diagram in this manual.
Page 22 2. Open the front panel of the indoor unit. 3. Using a screwdriver, remove the terminal block cover on the right side of the unit. This allows you to access the terminal block below. KEY: 1. Terminal block 2. Cover 3.
Page 23 STEP 7: Wrapping pipes and cables Before passing the pipes and cable through the hole in the wall, they must be wrapped together to save space, and to protect and in- sulate them. Indoor unit KEY: 1. Space behind unit 2.
Page 24 If the cooling pipes are already recessed in the wall, proceed as follows: Couple the top of the indoor unit to the upper hook of the fixing plate. Use a bracket or wedge to prop up the unit, leaving enough space to connect the cooling pipes, the signal pipe and the drain pipe. Connect the drain pipe and the cooling pipes (see dedicated paragraphs in this manual).

Page 29 STEP 4: Signal and power supply cable connection Attention Before doing any electrical work, read the warnings at the beginning of this manual. Before performing any electrical work or cleaning, be sure to cut off the power supply to the units. When stripping the wires, be sure to clearly identify the “L”...
Page 30 1.3.4 CONNECTION OF COOLING PIPE When the refrigerant pipes are connected, do not let substances or gases other than the specified refrigerant get in. The pressure of other gases or substances reduces the capacity of the unit and can cause an abnormally high pressure in the cooling cycle. This can cause explosions and injuries.
Page 31 ATTENTION FOR THE USE OF R32 REFRIGERANT When using a flammable refrigerant, the device must be kept in a well-ventilated area where the size of the room corresponds to the area of the room, as specified for operation. The device must be installed, used and kept in a room larger than 4m².
Page 32 Step 2: Remove any burrs Burrs can affect the tightness of the connection of the refrigerant pipes. They must be completely removed. Hold the pipe with a downwards angle to avoid the burrs from falling into the pipe. Using a reamer or a deburring machine, remove all of the burrs from the cut section of the pipe. Step 3: Flare the ends of the pipes Correct flaring is essential for obtaining water-tightness.
Page 33 ATTENTION MINIMUM CURVATURE RADIUS: when refrigerant pipes are bent, make sure that the minimum bending radius is at least 10cm. Radius 10 cm ≥10cm Raggio 1-29 Step 4: Pipe Connection When connecting refrigerant pipes, be careful not to use an excessive torque or not to deform the pipes in any way. One must first connect the low pressure pipe, then the high pressure one.
Page 34 • Outdoor Unit Unscrew the valve cover on the side of the outdoor unit. Remove the protective caps from the ends of the valves. Align the flared end of the pipe with each valve and tighten the flared nut as tight as possible by hand. Using a spanner, grip the valve body.
