IMPORTANT

These air conditioners employ
new refrigerant R410A.

Pay special attention when servicing
the unit.

< Combined Indoor Units >

1. How these units may be combined is given in
the Unit Combination Tables in the Appendix.

2. Be sure to operate the air conditioning
system only when 2 or more indoor units
have been installed. If operated with only a
single unit installed, the returning fluid to the
compressor may cause a malfunction.

Important!
Please Read Before Starting

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.

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 result
in severe personal injury or
death.

This symbol refers to a hazard or
unsafe practice which can result
in personal injury or product or
property damage.

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.

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.

Special Precautions

When Wiring

ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR
DEATH. ONLY A QUALIFIED,
EXPERIENCED ELECTRICIAN SHOULD
ATTEMPT TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and
tubing are completed or reconnected and checked.

• 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.

• Ground the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.

WARNING

CAUTION

WARNING

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.

When Installing…

…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.

…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.

…In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to
provide a solid, level foundation for the outdoor unit.
This prevents water damage and abnormal vibration.

…In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.

…In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is
higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

• Use the flare method for connecting tubing.

• 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.

• Check carefully for leaks before starting the test run.

When Servicing

• Turn the power off at the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.

• Keep your fingers and clothing away from any
moving parts.

• 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.

Others

• 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.

• 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.

• Do not install only on a single indoor unit.

Insulation of Refrigerant Tubing

Because capillary tubing is used in the outdoor unit, both the
wide and narrow tubes of this air conditioner become cold. To
prevent heat loss and wet floors due to dripping of
condensation, both tubes must be well insulated with a
proper insulation material. The thickness of the insulation
should be a min. 8 mm.

After a tube has been insulated,
never try to bend it into a narrow
curve because it can cause the tube
to break or crack.

NOTE

• This performance chart shows operation of a single wall-mounted indoor unit. The performance chart will vary depending on the indoor unit type.

• Check each performance value in test-run mode. Electrical performance values represent a combined indoor/outdoor value.(In this case, be sure to
stop all the indoor units where performance is not being checked.)

• The performance is for a tubing length of 7.5 m. If the tubing length is different, the performance chart will vary.
