Confirmation of parts attached
In addition to this manual, the following parts are supplied with the outdoor unit.
They are used for grounding the S terminals of transmission terminal blocks TB3,
TB7. For details refer to "6. Electrical work".

1. Safety precautions

► Before installing the unit, make sure you read all the "Safety precau-
tions".
► Please report to or take consent by the supply authority before connec-
tion to the system.
► Equipment complying with IEC/EN 61000-3-12
► It is designed for use in the residential, commercial and light-industrial
environment.
► PUMY-P200YKM
"This equipment complies with IEC 61000-3-12 provided that the short-
circuit power S is greater than or equal to S
sc
between the user's supply and the public system. It is the responsibility
of the installer or user of the equipment to ensure, by consulation with
the distribution network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power S
or equal to S (*1)"

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 components specifically made for use with R410A refrigerant.
The R410A refrigerant in the HFC system is pressurized 1.6 times the pressure
of usual refrigerants. If pipe components not designed for R410A refrigerant are
used and the unit is not installed correctly, the pipes may burst and cause dam-
age or injuries. In addition, water leakage, electric shock, or fire may result.
• The unit must be installed according to the instructions in order to minimize
the risk of damage from earthquakes, typhoons, or strong winds. An incor-
rectly installed unit may fall down and cause damage 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
damage or injuries.
• If the air conditioner is installed in a small room, measures must be taken to
prevent the refrigerant concentration in the room from exceeding the safety
limit in the event of refrigerant leakage. Consult a dealer regarding the appro-
priate 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 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. The units must be
powered by dedicated power lines and the correct voltage and circuit breakers
must be used. Power lines with insufficient capacity or incorrect electrical
work may result in electric shock or fire.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. If the pipes are not connected correctly, the
unit will not be properly grounded and electric shock may result.

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.
