Plastic parts may deteriorate and falloff or cause water leakage.▪ In places where the unit would be in the path of direct sunlight.▪ In bathrooms.▪ Sound sensitive areas (e.g. near a bedroom), so that theoperation noise will cause no trouble.WARNINGDo NOT place objects below the indoor and/or outdoor unitthat may get wet. Otherwise condensation on the unit orrefrigerant pipes, air filter dirt or drain blockage may causedripping, and objects under the unit may get dirty ordamaged.▪ Spacing. Install the unit at least 1.8 m from the floor and keep thefollowing requirements in mind for distances from the walls andthe ceiling:≥50 ≥50≥30(mm)Note: Make sure that there are no obstacles within 500 mm underthe signal receiver. They may influence reception performance of theuser interface.4.2 Preparing refrigerant piping4.2.1 Refrigerant piping requirementsRefrigerant piping diameterUse the same diameters as the connections on the outdoor units:Class L1 liquid piping L1 gas piping15~35 Ø6.4 Ø9.542+50 Ø6.4 Ø12.7Refrigerant piping material▪ Piping material: Phosphoric acid deoxidised seamless copper.▪ Flare connections: Only use annealed material.▪ Piping temper grade and thickness:Outer diameter(Ø)Temper grade Thickness (t)(a)6.4 mm (1/4") Annealed (O) ≥0.8 mmtØ9.5 mm (3/8")12.7 mm (1/2")(a) Depending on the applicable legislation and the unit'smaximum working pressure (see "PS High" on the unitname plate), larger piping thickness might be required.4.2.2 Refrigerant piping insulationPipe outer diameter(Øp)Insulation innerdiameter (Øi)Insulation thickness(t)6.4 mm (1/4") 8~10 mm ≥10 mm9.5 mm (3/8") 12~15 mm12.7 mm (1/2") 14~16 mmØiØitØpØpIf the temperature is higher than 30°C and the humidity is higherthan RH 80%, the thickness of the insulation materials should be atleast 20 mm to prevent condensation on the surface of theinsulation.5 Installation5.1 Opening the indoor unit5.1.1 To open the indoor unitTo open the front panel1 Hold the front panel on both sides and open it.2 Pull down both locks on the back of the front panel.3 Open the front panel until the support fits into the fixing tab.a dcba Lock (1 on each side)b Backside of the front panelc Fixing tabd SupportTo close the front panel1 Lift the front panel slightly and remove the support from thefixing tab.abca Backside of the front panelb Fixing tabc Support2 Close the front panel.
