securely so that the outside force of the cable is not
applied to the terminals.
- Inadequate connection and fastening may generate heat and
cause a fire.
• Have all electric work done by a licensed electrician
according to "Electric Facility Engineering Standard,"
"Interior Wire Regulations," and the instructions given in
this manual. Always use a circuit designated solely to the
unit.
- If the power source capacity is inadequate or electric work is
performed improperly, electric shock and fire may result.
• Securely install the cover of control box and the panel.
- If the cover and panel are not installed properly, dust or water
may enter the outdoor unit and fire or electric shock may
result.
• After completing service work, make sure that refrigerant
gas is not leaking.
- If the refrigerant gas leaks and is exposed to a fan heater,
stove, oven, or other heat source, it may generate noxious
gases.
• Do not try to defeat the safety features of devices, and do
not change the settings.
- If the pressure switch, thermal switch, or other protection
device is shorted and operated forcibly, or parts other than
those specified by Mitsubishi Electric are used, fire or
explosion may result.
