• When installing, relocating, or servicing the air conditioner,
use only the specified refrigerant written on the outdoor unit to
charge the refrigerant lines. Do not mix the refrigerant with any
other refrigerant, and do not allow air to remain in the lines.
- If air is mixed with the refrigerant, then it may cause abnormal high
pressure in the refrigerant lines, resulting in an explosion and other
hazards.
- The use of any refrigerant other than that specified for the
system will cause mechanical failure, system malfunction, or
unit breakdown. In the worst case, this could lead to a serious
impediment to securing product safety.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held
responsible for malfunctions or accidents resulting from the use of
the wrong type of refrigerant.
