Make sure nothing blocks the air flow.▪ Drainage. Make sure condensation water can be evacuatedproperly.▪ Wall insulation. When conditions in the wall exceed 30°C and arelative humidity of 80%, or when fresh air is inducted into thewall, then additional insulation is required (minimum 10 mmthickness, polyethylene foam).▪ Wall strength. Check whether the wall or the floor is strongenough to support the weight of the unit. If there is a risk, reinforcethe wall or the floor before installing the unit.▪ 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)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 piping20~35 Ø6.4 Ø9.5Refrigerant 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 mmtØ(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 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.
