1-1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY
• Be sure to read these safety precautions and instructions.
• Be sure to observe the warnings and cautions specified
here.
• After reading this manual, be sure to store it with the OPERATING
INSTRUCTIONS
for future reference.
• Please report to your supply authority or obtain their consent before connecting this equipment to the power supply system.
[] Do not install the unit by yourself (user).
Improper or incomplete installation
could cause fire, electric shock, injury due to
the unit falling, or water leakage. Consult a qualified installer or the dealer from
whom you purchased the unit.
[] Follow the instructions
detailed
in the installation
manual.
Incomplete
installation could cause fire or electric shock, injury due to the unit fall-
ing, or leakage of water.
[] Install
the unit securely
in a place that can bear the weight
of the unit.
If the installation location cannot bear the weight of the unit, the unit could fall
causing injury.
[] Perform
electrical
work according
to the installation
manual and be sure to use
an exclusive
circuit.
Do not connect
other electrical
appliances
to the circuit.
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.
[] Ground the unit correctly.
Do not connect the ground wire to a gas pipe, water pipe, lightning rod or tel-
ephone ground. Defective grounding
could cause electric shock.
[] Do not damage
the wires.
Damaged wires could cause fire.
[] Be sure to shut off the main power when setting
up the indoor P.O. hoard or
wiring.
Failure to do so could cause electric shock.
[] Use the specified
wires to securely
connect
the indoor and outdoor
units. At-
tach the wires firmly
to avoid applying
stress to the terminal
block.
Improper connection could cause fire.
[] Do not install the unit in a place where flammable
gas may leak.
If gas leaks and accumulates
around the unit, it could cause an explosion.
[] Do not use intermediate
connection
of the power cord or the extension
cord.
Do not connect
many devices
to one AC outlet.
It could cause a fire or an electric shock.
[] Use the parts 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.
[] When plugging the power supply
plug into the outlet,
make sure that there is
no dust, blockage,
or loose parts both in the outlet
and on the plug. Verify that
the power supply
plug is completely
in the outlet.
If there is dust, blockage, or loose parts on the power supply plug or the outlet, it could
cause electric shock or fire. If loose parts are found on the power supply plug, replace it.
[] Securely attach the electrical
cover to the indoor unit and the service
panel to
the outdoor
unit.
If the electrical cover of the indoor unit and/or the service panel of the outdoor unit are
not attached securely, dust, water, etc. could collect in the unit and could cause a fire or
an electric shock.
[] When installing or relocating
the unit, make sure that no substance
other than
the specified
refrigerant
(R410A) enters the refrigerant circuit.
Any foreign substances
in the refrigerant circuit can cause abnormal pressure rise
or an explosion.
[] Do not discharge the refrigerant into the atmosphere. Check that the refrigerant
gas
does not leak after installation
has been completed.
If refrigerant
leaks during
installation, ventilate the room.
If refrigerant comes in contact with a fire, harmful gas could be generated.
If refrigerant gas leaks indoors, and comes into contact with the flame of a fan
heater, space heater, stove, etc., harmful gases will be generated.
[] Use appropriate
tools and piping materials
for installation.
The pressure of R410A is 1.6 times higher than R22. Not using the appropriate
tools and materials, or improper installation
could cause the pipes to burst causing
an injury.
[] When pumping down the refrigerant, stop the compressor
before disconnecting
the refrigerant
pipes.
If the refrigerant
pipes are disconnected
while the compressor
is running and the
stop valve is open, air could be drawn in and the pressure in the refrigeration
cycle
could become abnormally
high, causing the pipes to burst.
[] When installing the unit, securely
connect
the refrigerant pipes before starting
the compressor.
If the compressor
is started before the refrigerant pipes are connected
and the
stop valve is open, air could be drawn in and the pressure in the refrigeration
cycle
could become abnormally
high, causing the pipes to burst.
[] Fasten a flare nut with a torque wrench as specified
in this manual.
If fastened too tight, a flare nut could break and cause refrigerant
leakage.
[] install
the unit
according
to national wiring regulations.
[] Depending
on the installation
area, install a Ground
Fault Interrupt
(GFI) circuit
[] Do not touch
the air inlet or the aluminum
fins of the outdoor
unit.
breaker.
If the Ground Fault Interrupt (GFI) circuit breaker is not installed, an electric shock
could occur.
[] Perform
the drainage/piping
work
securely
according
to the installation
manual.
If there is defect in the drainage/piping
work, water could drip from the unit, and
damage household
items.
\
•
This could cause injury.
[] Do not install the outdoor
unit where small animals
may live.
If small animals enter the unit and damage its electrical parts, it could cause a
malfunction,
smoke emission, or fire. Keep the area around the unit clean.
