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.
