INSTALLATION MANUAL
1. BEFORE INSTALLATION
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 falling,
or leakage of water.
When installing the unit, use appropriate protective equipment and tools for
safety.
Failure to do so could cause injury.
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 telephone
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.C. board 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.
Depending on the installation area, install a Ground Fault Interrupt (GFI) circuit
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.

When installing multi units, refer to the instal-
lation manual of the multi unit for outdoor unit
installation.
WARNING
CAUTION
Required Tools for Installation
Phillips screwdriver
Level
Scale
Utility knife or scissors
3 in. (75 mm) hole saw
Torque wrench
Wrench (or spanner)
(Could lead to death or serious injury.)
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, relocating, or servicing the unit, make sure that no substance
other than the specified refrigerant (R410A) enters the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pressure rise and
may result in explosion or injury. The use of any refrigerant other than that specified
for the system will cause mechanical failure, system malfunction, or unit breakdown. In
the worst case, this could lead to a serious impediment to securing product safety.
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.
(Could lead to serious injury when operated incorrectly.)
Do not touch the air inlet or the aluminum fins of the outdoor unit.
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 mal-
function, smoke emission, or fire. Keep the area around the unit clean.
