4 Preparation

4.1 Preparing the installation site

WARNING

The appliance shall be stored in a room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).

4.1.1 Installation site requirements of the indoor unit

INFORMATION

The sound pressure level is less than 70 dBA.

• Air flow. Make sure nothing blocks the air flow.

• Drainage. Make sure condensation water can be evacuated properly.

• Wall insulation. When conditions in the wall exceed 30°C and a relative humidity of 80%, or when fresh air is inducted into the wall, then additional insulation is required (minimum 10 mm thickness, polyethylene foam).

• Wall strength. Check whether the wall or the floor is strong enough to support the weight of the unit. If there is a risk, reinforce the wall or the floor before installing the unit.
• Spacing. Install the unit at least 1.8 m from the floor and keep the following requirements in mind for distances from the walls and the ceiling:

≥30 ≥50 ≥50 (mm)

4.2 Preparing refrigerant piping

4.2.1 Refrigerant piping requirements

Refrigerant piping diameter

Use the same diameters as the connections on the outdoor units:

Class	L1 liquid piping	L1 gas piping
20~35	∅6.4	∅9.5

Refrigerant piping material

• Piping material: Phosphoric acid deoxidised seamless copper.
• Flare connections: Only use annealed material.
• Piping temper grade and thickness:

Outer diameter (∅)	Temper grade	Thickness (t)(a)
6.4 mm (1/4")	Annealed (O)	≥0.8 mm

(a) Depending on the applicable legislation and the unit's maximum working pressure (see "PS High" on the unit name plate), larger piping thickness might be required.

4.2.2 Refrigerant piping insulation

Pipe outer diameter ( _p )	Insulation inner diameter ( _i )	Insulation thickness (t)
6.4 mm (1/4")	8~10 mm	≥10 mm

If the temperature is higher than 30^ C and the humidity is higher than RH 80%, the thickness of the insulation materials should be at least 20 mm to prevent condensation on the surface of the insulation.
