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.

Install power cables at least 1metre away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 3metres may NOT be sufficient.

▪ Choose a location where the hot/cold air discharged from the unit

or the operation noise, will NOT disturb anyone.

▪ Fluorescent lights. When installing a wireless user interface in a

room with fluorescent lights, mind the following to avoid interference:

▪ Install the wireless user interface as close as possible to the

indoor unit.

▪ Install the indoor unit as far as possible from the fluorescent

lights.

(mm)

ØiØ

ØpØ

b c

It is NOT recommended to install the unit in the following places because it may shorten the life of the unit:

▪ Where the voltage fluctuates a lot

▪ In vehicles or vessels

▪ Where acidic or alkaline vapour is present

▪ In places where a mineral oil mist, spray or vapour may be

present in the atmosphere. Plastic parts may deteriorate and fall off 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 the

operation noise will cause no trouble.

WARNING

Do NOT place objects below the indoor and/or outdoor unit that may get wet. Otherwise condensation on the unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, and objects under the unit may get dirty or damaged.

▪ 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:

4.2.2 Refrigerant piping insulation

Pipe outer diameter

(Øp)

6.4mm (1/4") 8~10mm ≥10mm

9.5mm (3/8") 12~15mm

12.7mm (1/2") 14~16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.
