correctly.
■ The dangers and degree that could occur if handling is mistaken are ranked with the following
symbols.
WARNING When fatalities or serious injuries could result if handling is mistaken.
CAUTION
When personal injury, or damage to house or assets could result if handling is mistaken.
■ After reading this manual store it in a safe place together with the installation manual for future
reference.
When changing users, always give this manual and the installation manual to the new user.

WARNING
■ Unit must not be installed by user.
Always contact your dealer or a specialist to install the unit. Improper installation by the user could result in
electric shocks or fires, etc.
■ Check the installation state.
Always check that the unit is installed on a solid place where it will not fall off.
■ Stop immediately when error occurs.
Continuing operation in an erroneous state could result in trouble, electric shocks or fires, etc. If any abnormality is sensed (burning smell, etc.), always stop the operation, turn the power switch OFF, and contact
your dealer.
■ Unit must not be moved and re-installed by user.
Improper installation by the user could result in electric shocks or fires, etc.
Always contact your dealer or a specialist when the unit must be moved.
■ Unit must not be disposed by user.
Contact your dealer when the unit must be disposed of.
■ Never modify or repair the unit.
Improper modifications or repairs could result in electric shocks or fires, etc. Always consult your dealer for
repairs.
■ Stop operation if operation is inhibited with an error display or if a fault occurs.
Continuing operation could result in fires or faults.
Contact your dealer.
CAUTION
■ Do not place hazardous objects near unit.
Do not install this unit where flammable gases could leak. If flammable gases leak and accumulate around
the unit, fires or explosions could result.
■ Do not wash this unit with water.
Washing the unit with water could result in electric shocks or faults.
■ Do not operate switches with wet hands.
Touching the unit with wet hands could result in electric shocks or faults.
■ Do not use for special applications.
This product is intended for use with the Mitsubishi Electric building air conditioning control system. Do not
use for the control of other air conditioners or for other applications.
Failure to observe this could result in malfunctioning.
■ Do not spray insecticide or flammable sprays onto unit.
Do not place flammable sprays, etc., near the unit or spray these directly onto the unit.
Doing so could result in fires or explosions.
■ Do not use in special environments.
Using this product in environments containing a high level of oil (including machine oil), vapors or sulfuric
gases, etc., could result in a drop in performance or damage of parts.
■ Do not press switches with pointed objects.
Pressing with pointed objects could result in electric shocks or faults.
■ Observe the working temperature range.
Always observe the working temperature range. Serious faults could result if the unit is used outside the
working temperature range.
Refer to the specifications in the instruction manual for the working temperature range.
If not indicated in the instruction manual, the range is 0°C to 40°C (32°F to 104°F).
■ Do not pull or twist the transmission cables
Doing so could result in fires or faults.
■ Do not disassemble this unit.
Touching the internal PCBs, etc., is hazardous, and could result in fires or faults.
■ Do not wipe this unit with benzene, thinner or chemical rags.
Using these matters could result in discoloration or faults. If the unit is heavily dirtied, wipe off with a cloth
wetted in diluted neutral detergent, and then wipe again with a dry cloth.

4-1. When "COLLECTIVE ON/OFF LAMP" and "ERROR
CODE" are flickering
• The air conditioner is stopped because a problem has occurred and operation cannot be
continued.
• Check the address of the unit where the error is occurring and the error code, and call your
nearest MITSUBISHI ELECTRIC supplier or dealer.
The COLLECTIVE ON/OFF lamp flickers.
The address No. of the faulty unit and the attributes
alternately flicker and display.
The error code flickers and displays. (4-digit)
The operation status for each group containing
the faulty unit is displayed.

error for the group containing the first problem will appear.
2. If the error occurs while the [Group Setting/Monitor Screen] is displayed, the error will display
only when the currently selected group has the error.
3. If an error occurs in several groups, the operation status display for each group having an
error will flicker, so check the details of the error with "Checking errors in a different group".
• Checking errors in a different group
Press the GROUP switch to select the group with the error, and check the details of the
error.
1. If an error occurs in a group other than that displayed on the [Group Setting/Monitor
Screen], the COLLECTIVE ON/OFF lamp and the group operation status of the
group with the error will flicker.
2. The details of past errors can be confirmed. Refer to section "7. Error history monitor"
for details.
4-2. When "group operation status display" and "error code"
are flickering
• The air conditioner will continue operation, but there may be a problem.
• Check the error code and contact your dealer or service center.
The error code flickers. (4-digit)
The operation status for each group containing
the faulty unit is displayed.
