If air enters in the refrigerant circuit, the pressure in the refrigerant circuit
becomes too high, which can cause burst and personal injury.
• Do not processing, splice the power cord, or share a socket with
other power plugs.
This may cause fire or electric shock due to defecting contact, defecting
insulation and over-current etc.
• Do not bundling, winding or processing for the power cord. Or, do
not deforming the power plug due to tread it.
This may cause fire or heating.
• Do not vent R410A into the atmosphere : R410A is a fluorinated
greenhouse gas, covered by the Kyoto Protocol with Global
Warming Potential (GWP)=1975.
• Do not run the unit with removed panels or protections.
Touching rotating equipments, hot surfaces or high voltage parts can cause
personal injury due to entrapment, burn or electric shocks.
• Do not perform any change of protective device itself or its setup
condition.
The forced operation by short-circuiting protective device of pressure
switch and temperature controller or the use of non specified component
can cause fire or burst.
