Warning:
Describes precautions that should be observed to prevent danger of injury or
death to the user.
Caution:
Describes precautions that should be observed to prevent damage to the
unit.
Warning:
• Carefully read the labels affixed to the main unit.
• Ask a dealer or an authorized technician to install, relocate and repair the
unit.
• The user should never attempt to repair the unit or transfer it to another
location.
• For installation and relocation work, follow the instructions in the Installation
Manual and use tools and pipe components specifically made for use with
refrigerant specified in the outdoor unit installation manual.
• The unit must be installed according to the instructions in order to
minimize the risk of damage from earthquakes, typhoons, or strong winds.
An incorrectly installed unit may fall down and cause damage or injuries.
• Do not alter the unit. It may cause fire, electric shock, injury or water
leakage.
• The unit must be securely installed on a structure that can sustain its
weight.
• The appliance shall be stored in a well-ventilated area where the room size
corresponds to the room area as specified for operation.
• If the air conditioner is installed in a small room or closed room, measures
must be taken to prevent the refrigerant concentration in the room from
exceeding the safety limit in the event of refrigerant leakage. Should the
refrigerant leak and cause the concentration limit to be exceeded, hazards
due to lack of oxygen in the room may result.
• Keep gas-burning appliances, electric heaters, and other fire sources
(ignition sources) away from the location where installation, repair, and
other air conditioner work will be performed.
If refrigerant comes into contact with a flame, poisonous gases will be
released.
• Ventilate the room if refrigerant leaks during operation. If refrigerant comes
into contact with a flame, poisonous gases will be released.
• All electric work must be performed by a qualified technician according to
local regulations and the instructions given in this manual.
• Do not use intermediate connection of the electric wires.
• Use only specified cables for wiring. The wiring connections must be made
securely with no tension applied on the terminal connections. Also, never
splice the cables for wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a fire.
• When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant written on outdoor unit to charge the refrigerant lines.
Do not mix it with any other refrigerant and do not allow air to remain in the
lines.
en
I f air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.

After installation work has been completed, explain the "Safety Precautions," use,
and maintenance of the unit to the customer according to the information in the
Operation Manual and perform the test run to ensure normal operation. Both the
Installation Manual and Operation Manual must be given to the user for keeping.
These manuals must be passed on to subsequent users.
The use of any refrigerant other than that specified for the system will
cause mechanical failure or system malfunction or unit breakdown. In the
worst case, this could lead to a serious impediment to securing product
safety.
• The appliance shall be installed in accordance with national wiring
regulations.
• This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the
appliance.
• The terminal block cover panel of the unit must be firmly attached.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
• Use only authorized accessories by Mitsubishi Electric and ask a dealer or
an authorized technician to install them.
If accessories are incorrectly installed, water leakage, electric shock, or fire
may result.
• After installation has been completed, check for refrigerant leaks. If
refrigerant leaks into the room and comes into contact with the flame of a
heater or portable cooking range, poisonous gases will be released.
• Do not use means to accelerate the defrosting process or to clean, other
than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating
ignition sources (for example: open flames, an operating gas appliance or
an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Pipe-work shall be protected from physical damage.
• The installation of pipe-work shall be kept to a minimum.
• Compliance with national gas regulations shall be observed.
• Keep any required ventilation openings clear of obstruction.
• Do not use low temperature solder alloy in case of brazing the refrigerant
pipes.
• When performing brazing work, be sure to ventilate the room sufficiently.
Make sure that there are no hazardous or flammable materials nearby.
When performing the work in a closed room, small room, or similar
location, make sure that there are no refrigerant leaks before performing
the work.
If refrigerant leaks and accumulates, it may ignite or poisonous gases may
be released.
• Exercise caution when using any auxiliary heat source and follow all third
party manufacturer instructions and safety guidelines for installation and
usage.
Any auxiliary heat source connected to this unit via the CN24 connection
must have an independent temperature control mechanism. Failure to
install and maintain such temperature control mechanism may void the
warranty for this unit.
Mitsubishi Electric shall not bear any warranty obligation or other liability
for any damage or loss in connection with such third party auxiliary
heaters.
