WARNING
Securely attach the terminal block cover (panel) to the 
unit.
If the terminal block cover (panel) is not installed properly, 
dust and/or water may infiltrate and pose a risk of electric 
shock, smoke, and/or fire.
Only use the type of refrigerant that is indicated on the 
unit when installing or reinstalling the unit.
Infiltration of any other type of refrigerant or air into the unit 
may adversely affect the refrigerant cycle and may cause 
the pipes to burst or explode.
When installing the unit in a small room, exercise cau-
tion and take measures against leaked refrigerant 
reaching the limiting concentration.
Consult your dealer with any questions regarding limiting 
concentrations and for precautionary measures before in-
stalling the unit. Leaked refrigerant gas exceeding the lim-
iting concentration causes oxygen deficiency.
Consult your dealer or a specialist when moving or re-
installing the unit.
Improper installation may result in water leakage, electric 
shock, and/or fire.
After completing the service work, check for a gas 
leak.
If leaked refrigerant is exposed to a heat source, such as a 
fan heater, stove, or electric grill, poisonous gases may be 
produced.
Do not try to defeat the safety features of the unit.
Forced operation of the pressure switch or the temperature 
switch by defeating the safety features of these devices, or 
the use of accessories other than the ones that are recom-
mended by MITSUBISHI may result in smoke, fire, and/or 
explosion.
Only use accessories recommended by MITSUBISHI.
Ask a qualified technician to install the unit. Improper instal-
lation by the user may result in water leakage, electric 
shock, smoke, and/or fire.
Control box houses high-voltage parts.
When opening or closing the front panel of the control box, 
do not let it come into contact with any of the internal com-
ponents. Before inspecting the inside of the control box, 
turn off the power, keep the unit off for at least 10 minutes, 
and confirm that the voltage between FT-P and FT-N on 
INV Board has dropped to DC20V or less. (It takes about 
10 minutes to discharge electricity after the power supply  is 
turned off.)
