IMPORTANT!
Please Read Before Starting
When Installing…
This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an
important part of your job to install or service the system
so it operates safely and efficiently.
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
For safe installation and trouble-free operation, you
must:
● Carefully read this instruction booklet before beginning.
● Follow each installation or repair step exactly as shown.
● Observe all local, state, and national electrical codes.
● Pay close attention to all warning and caution notices
given in this manual.
This symbol refers to a hazard
or unsafe practice which can
WARNING
result in severe personal injury
or death.
This symbol refers to a hazard
or unsafe practice which can
CAUTION
result in personal injury or
product or property damage.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
When Connecting Refrigerant Tubing
• Do not add any refrigerant, air, or substance into the
refrigeration circuit other than the designated refrigerant (R410A). Adding anything other than the specified
refrigerant may cause the pressure to rise excessively
in the refrigeration circuit, rupturing the circuit and
causing injury or damage.
• Use all-new tubing and flare nuts to make the tubing
connections. Using any previous parts (from R22based systems) may result in damage to the equipment, and may lead to the refrigeration circuit rupturing, causing a serious accident.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for
a special problem, contact our sales/service outlet or
your certified dealer for additional instructions.
• Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them,
then tighten the nut with a torque wrench for a leakfree connection.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
• Check carefully for leaks before starting the test run.
When Servicing
SPECIAL PRECAUTIONS
WARNING
• Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.
When Wiring
• Keep your fingers and clothing away from any moving
parts.
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
• Clean up the site after you finish, remembering to
check that no metal scraps or bits of wiring have been
left inside the unit being serviced.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.
Others
• Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and
these instructions when wiring. Improper connections
and inadequate grounding can cause accidental
injury or death.
CAUTION
• Ventilate any enclosed areas when installing or testing the
refrigeration system. Escaped refrigerant gas, on contact
with fire or heat, can produce dangerously toxic gas.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
• Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.

2-2. Embedding the Tubing and Wiring
●
Before beginning embedding installation work, consult fully with agencies or offices related to the building’s foundation, construction, electricity, and water.
●
Wait to make connections to the embedded portion.
Each connection step is described later in this
manual.
●
Securely cover the end of the embedded tubing to
prevent intrusion of dirt or moisture.
●
If an embedded tube is to be left for a long time, fill
the tube with nitrogen and seal both ends securely.
If a tube is left open for an extended time, moisture
in the air inside the tubing may condense into water
droplets, and lead to water contamination of the
refrigerant circuit.
●
In order to prevent insulation breakdown and ground
faults, do not allow wiring ends to come in contact with
rainwater, or be subjected to condensation or dew.
●
Apply sufficient thermal insulation to the refrigerant
tubing and drain pipes.

4. How to Secure the Wireless Remote
Control Unit
The remote control unit can be operated from either a
non-fixed position or a wall-mounted position.
To ensure that the air conditioner operates correctly, do
not install the remote control unit in the following
places:
● In direct sunlight
● Behind a curtain or other place where it is covered
● More than 8 m away from the air conditioner
● In the path of the air conditioner’s airstream
● Where it may become extremely hot or cold
● Where it may be subject to electrical or magnetic
interference
4-1. Mounting on a Wall
a) Removable mounting
1) Confirm the indoor unit beeps when the
ON/OFF button is pressed at the wall location
where the remote control unit is to be attached,
then attach the holder to the wall. (Fig. 32)
