The controller should be repaired or moved only by
qualified personnel.
Do not disassemble or modify the controller.
Improper installation or repair may cause injury, electric
shock, or fire.
To reduce the risk of shorting, electric shock, fire, or
malfunction, do not touch the circuit board with tools or
with your hands, and do not allow dust to accumulate
on the circuit board.
To avoid damage to the controller, use appropriate
tools to install, inspect, or repair the controller.
This controller is designed for exclusive use with the
Building Management System by Mitsubishi Electric.
The use of this controller for with other systems or for
other purposes may cause malfunctions.
Take appropriate measures against electrical noise
interference when installing the air conditioners in
hospitals or facilities with radio communication
capabilities. Inverter, high-frequency medical, or
wireless communication equipment as well as power
generators may cause the air conditioning system to
malfunction. Air conditioning system may also
adversely affect the operation of these types of
equipment by creating electrical noise.
To avoid malfunctions, do not bundle power cables and
signal cables together, or place them in the same
metallic conduit.
To prevent malfunctions, do not remove the protective
film or the circuit board from the casing.
To avoid damage to the controller, do not overtighten
the screws.
Use a flat-head screwdriver with a blade width of 4-5.5 mm
(5/32-7/32 in). The use of a screwdriver with a narrower or
wider blade tip may damage the controller casing.
To prevent damage to the controller casing, do not
force the driver to turn with its tip inserted in the slot.
To avoid discoloration, do not use benzene, thinner, or
chemical rag to clean the controller. To clean the
controller, wipe with a soft cloth soaked in water with
mild detergent, wipe off the detergent with a wet cloth,
and wipe off water with a dry cloth.
To avoid damage to the controller, provide protection
against static electricity.
Do not use solderless terminals to connect cables to
the terminal block.
Solderless terminals may come in contact with the
circuit board and cause malfunctions or damage the
controller cover.
To avoid damage to the controller, do not make holes
on the controller cover.
To avoid deformation and malfunction, do not install
the remote controller in direct sunlight or where the
ambient temperature may exceed 40ºC (104ºF) or
drop below 0ºC (32ºF).
Do not install the controller on the control panel door.
Vibrations or shocks to the controller may damage the
controller or cause the controller to fall.
Hold the cables in place with clamps to prevent undue
force from being applied to the terminal block and
causing cable breakage.
To prevent cable breakage and malfunctions, do not
hang the top controller casing hang by the cable.
