1. Safety precautions
• Please report to or take consent by the supply authority before connection to
the system.
• Be sure to read "Safety precautions" before installing the air conditioner.
• Be sure to observe the cautions specified here as they include important
items related to safety.
• The indications and meanings are as follows.
Warning:
Describes precautions that should be observed to prevent danger of injury or
death to the user.
Caution:
Could lead to serious injury in particular environments when operated
incorrectly.
• After reading this manual, be sure to keep it together with the instruction
manual in a handy place on the customer's site.
Warning:
• Do not install it by yourself (customer).
Incomplete installation could cause injury due to fire, electric shock, the unit
falling or leakage of water. Consult the dealer from whom you purchased the
unit or special installer.
• Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall causing
injured.
• 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.
• Do not use intermediate connection of the power cord or the extension cord
and do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective
insulation, exceeding the permissible current, etc.
• 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.
• Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric
shock, the unit falling or leakage of water.
• All electric work must be performed by a qualified technician according to
local regulations and the instructions given in this manual.
If the capacity of the power circuit is insufficient or there is incomplete
electrical work, it could result in a fire or an electric shock.
• Attach the electrical part cover to the indoor unit and the service panel to the
outdoor unit securely.
If the electrical part cover in the indoor unit and/or the service panel in the
outdoor unit are not attached securely, it could result in a fire or an electric
shock due to dust, water, etc.
• Be sure to use the part provided or specified parts for the installation work.
The use of defective parts could cause an injury or leakage of water due to a
fire, an electric shock, the unit falling, etc.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will 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.
• 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.

This Installation Manual describes only for the indoor unit and the connected
outdoor unit of PUHZ series.
If the connected outdoor unit is MXZ series, refer to the Installation Manual for
MXZ series.
Symbols put on the unit
: Indicates an action that must be avoided.
: Indicates that important instructions must be followed.
: Indicates a part which must be grounded.
: Indicates that caution should be taken with rotating parts.
: Indicates that the main switch must be turned off before servicing.
: Beware of electric shock.
: Beware of hot surface.
Warning:
Carefully read the labels affixed to the main unit.
• Do not alter the unit. It may cause fire, electric shock, injury or water leakage.
• 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.
• 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.
• 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.
If 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. 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.
• 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 accessories authorized by Mitsubishi Electric and ask a dealer or an
authorized technician to install them.
• 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.
