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.

Operation range
▪ 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:
≥50

Refrigerant piping requirements

Refrigerant piping diameter
Use the same diameters as the connections on the outdoor units:
Class L1 liquid piping
20~35 Ø6.4
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

6.4 mm (1/4") Annealed (O)
(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.

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
