Your MITSUBISHI ELECTRIC product is designed and manufactured with high quality materials and components which can be recycled and/or reused.
This symbol means that electrical and electronic equipment, batteries and accumulators, at their end-of-life, should be disposed of separately from your
household waste.
If a chemical symbol is printed beneath the symbol shown above, this chemical symbol means that the battery or accumulator contains a heavy metal
at a certain concentration. This will be indicated as follows:
Hg: mercury (0,0005%), Cd: cadmium (0,002%), Pb: lead (0,004%)
In the European Union there are separate collection systems for used electrical and electronic products, batteries and accumulators.
Please, dispose of this equipment, batteries and accumulators correctly at your local community waste collection/recycling centre.

1. Safety precautions
► Before installing the unit, make sure you read all the "Safety
precautions".
en
Warning:
Precautions that must be observed to prevent injuries or death.
Caution:
Precautions that must be observed to prevent damages to the unit.
Warning:
• The unit must not be installed by the user. Ask an installer or an authorized
technician to install the unit. If the unit is installed improperly, water leakage,
electric shock, or fire hazard may be caused.
• The unit must be installed according to the instructions in order to minimize
the risk of damages by earthquakes, typhoons, or strong winds.
An improperly installed unit may fall down and cause damages or injuries.
• The unit must be securely installed on a structure that can sustain its weight.
If the unit is mounted on an unstable structure, it may fall down and cause
damages or injuries.
• If the outdoor unit is installed in an enclosed area, measures must be taken
to prevent the refrigerant concentration in the room in the event of
refrigerant leakage. Consult an installer regarding the appropriate measures.
Should the refrigerant leak and cause the concentration oxygen in the room
may lack.
• All electric work must be performed by a qualified technician according to
local regulations and the instructions given in this manual. The units must
be powered by dedicated power lines and the correct voltage and isolating
switch must be used. Power lines with insufficient capacity or incorrect
electrical work may result in electric shock or fire hazard.
• 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 hazard.
• Terminal block cover panel of the outdoor unit must be firmly fixed. If the
cover panel is mounted improperly, dust and moisture may enter the unit,
and it may cause electric shock or fire hazard.
• Make sure to use accessories authorized by Mitsubishi Electric and ask an
installer or an authorized technician to install them. If accessories are improperly
installed, it may cause water leakage, electric shock, or fire hazard.
1.1. Before installation
Caution:
• Do not use the unit in an unusual environment. If the outdoor unit is
installed exposed to steam, volatile oil (including machine oil), or sulfuric
gas, or exposed to briny air, or covered with snow, the performance can be
significantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced,
flow, or accumulate. If combustible gas accumulates around the unit, it may
cause fire hazard or explosion.
• The outdoor unit produces condensate during the heating operation. Make
sure to provide drainage around the outdoor unit if such condensate is
likely to cause damage.

After installation, perform the test run to ensure normal operation. Then explain to
your customer the "Safety Precautions," use, and maintenance of the unit based
on the information in the Operation Manual. Both the Installation Manual and the
Operation Manual must be given to the user. These manuals must always be kept
by the actual users.
: Indicates a part which must be earthed.
Warning:
Carefully read the labels attached to the unit.
• Do not remodel the unit. Consult an installer for repairs. If alterations or
repairs are not performed correctly, it may cause water leakage, electric
shock, or fire hazard.
• The user should never attempt to repair the unit or transfer it to another location.
If the unit is installed improperly, it may cause water leakage, electric shock,
or fire hazard. If the outdoor unit needs to be repaired or moved, ask an
installer or an authorized technician.
• After installation has been completed, make sure that refrigerant does not
leak.
• Be sure always use the specified antifreeze solution. The deterioration of
antifreeze quality may result in the system breakdown or the water leakage.
• Never use anything other than antifreeze as a medium. It may cause a fire
hazard or an explosion.
• Do not directly use heated that is produced by the air to water heat pump as
drinking and cooking water.
• 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.
• When installing the unit in a hospital or in a building where communication
equipment is installed, you may need to take measures to reduce noise and
electronic interference. Inverters, home appliances, high-frequency medical
equipment, and radio communications equipment can cause the outdoor
unit to malfunction or to breakdown. At the same time, the noise and
electronic interference from the outdoor unit may disturb the proper
operation of medical equipment, and communications equipment.
• If the unit is connected to deteriorated emitters, it may reduce water quality
within heating circuit. And it may cause resulting in a significant decrease in
performance of the unit or damages of parts.
