Caution:
• Do not vent R410A into the atmosphere.

1. Safety precautions

► Before installing the unit, make sure you read all the "Safety precautions".
► Please report to or take consent by the supply authority before connec-
tion to the system.
► Equipment complying with IEC/EN 61000-3-12
(PUHZ-ZRP100/125/140VKA3)
► PUHZ-ZRP200/250Y, P200/250Y
"This equipment complies with IEC 61000-3-12 provided that the short-
is greater than or equal to S
circuit power 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 consultation with
the distribution network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power S
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 leak-
age, 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 refrig-
erant. 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 damage 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 ap-
propriate measures to prevent the allowable concentration from being ex-
ceeded. 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 cor-
rectly, the unit will not be properly grounded and electric shock may result.
1.1. Before installation
Caution:
• Do not use the unit in an unusual environment. If the air conditioner is in-
stalled in areas exposed to steam, volatile oil (including machine oil), or
sulfuric gas, areas exposed to high salt content such as the seaside, or
areas where the unit will be covered by snow, the performance can be sig-
nificantly 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, fire or
explosion may result.

specified refrigerant (R410A) 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.
