1. Safety precautions

► Before installing the unit, make sure you read all
the "Safety precautions".
► Please report to or take consent by the supply au-
thority before connection to the system.
► Equipment complying with IEC/EN 61000-3-12
(PUHZ-W112VAA)
Warning:
Describes precautions that must be observed to pre-
vent danger of injury or death to the user.
Caution:
Describes precautions that must be observed to pre-
vent damage to the unit.
Warning:
• The unit must not be installed by the user. Ask a
dealer or an authorized technician to install the unit.
If the unit is installed incorrectly, water leakage,
electric shock, or fire may result.
• For installation work, follow the instructions in the
Installation Manual and use tools and pipe compo-
nents specifically made for use with R410A refrig-
erant. The R410A refrigerant in the HFC system is
pressurized 1.6 times the pressure of usual refrig-
erants. If pipe components not designed for R410A
refrigerant are used and the unit is not installed cor-
rectly, the pipes may burst and cause damage or
injuries. In addition, water leakage, electric shock,
or fire may result.
• The unit must be installed according to the instruc-
tions in order to minimize the risk of damage from
earthquakes, typhoons, or strong winds. An incor-
rectly installed unit may fall down and cause dam-
age or injuries.

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 opera-
tion. Both the Installation Manual and Operation Manual
must be given to the user for keeping. These manuals
must be passed on to subsequent users.
: Indicates a part which must be grounded.
Warning:
Carefully read the labels affixed to the main unit.
• 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
damage or injuries.
• If the outdoor unit is installed in a small room,
measures must be taken to prevent the refriger-
ant concentration in the room from exceeding the
safety limit in the event of refrigerant leakage. Con-
sult a dealer regarding the appropriate measures
to prevent the allowable concentration from being
exceeded. Should the refrigerant leak and cause the
concentration limit to be exceeded, hazards due to
lack of oxygen in the room may result.
• Ventilate the room if refrigerant leaks during opera-
tion. If refrigerant comes into contact with a flame,
poisonous gases will be released.
