Installation location

Precautions Keep the indoor unit and outdoor unit accessible at all times.
If you install the indoor unit in a small room, take appropriate measures (ventilation) to prevent the refrig­
erant from exceeding the concentration limit even if it leaks. Consult the Installation chapter when you
implement the measures.
Accumulation of highly concentrated refrigerant may cause an oxygen deficiency accident.
Install the indoor unit and outdoor unit on a solid, stable structure able to bear its weight.
Install the indoor unit in a frost-free location.
Do not install the indoor unit in a location where it is directly exposed to sunlight.
Do not install the indoor unit in a location that may be subject to a risk of exposure to combustible gas. If
there is a combustible gas leak and the gas becomes concentrated around the unit, a fire may occur.
Do not install the air conditioner in a place that has an atmosphere with a high salt content or in any cor­
rosive environment.
Do not install the air conditioner in a place exposed to steam and combustion gases.
Do not install the outdoor unit in a place where it may be covered in snow.
1.5

Refrigerant piping

Precautions Use tools and pipe components especially designed for use with R32 refrigerant.
Use copper pipes deoxidised with phosphorus to carry the refrigerant.
Store the refrigerant connection pipes away from dust and humidity (risk of damage to the compressor).
Apply refrigerant oil to the beaded parts to facilitate tightening and improve the leak-tightness.
Protect the outdoor unit and indoor unit, including the insulation and structural elements. Do not overheat
the pipes as brazed components may cause damage.
Protect pipes from physical damage.
Insulate the pipes to reduce heat losses to a minimum.
Do not touch the refrigeration connection pipes with your bare hands while the air conditioner is running.
Danger of burn or frost injury.
1.6

Maintenance and repair work

Precautions Do not disassemble to repair the unit while it is running.
Use only dehydrated nitrogen for detecting leaks or for pressurised tests.
After maintenance or repair work, check the entire air conditioning system to ensure that there are no
leaks.
Remove the casing only to perform maintenance and repair work. Put the casing back in place after
maintenance and repair work.

Recommendations

Operation Keep the indoor unit and outdoor unit accessible at all times.
Installation Install the air conditoner's indoor unit in a frost-free location.
Install the air conditoner's indoor unit and outdoor unit on a solid, stable structure able to bear its weight.
Insulate the pipes to reduce heat losses to a minimum.
Do not make any modifications to the air conditioner without the written consent of the manufacturer.
To benefit from warranty cover, no modifications should be made to the appliance.
Do not install the air conditioner in a place that:
has an atmosphere with a high salt content,
is exposed to steam and combustion gas,
may get covered in snow.
