IMPORTANT!
When Transporting
Please Read Before Starting
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.
This air conditioner must be installed by the sales dealer or
installer.
This information is provided for use only by authorized persons.
For safe installation and trouble-free operation, you must:
When Installing…
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
This air conditioner shall be installed in accordance with
National Wiring Regulations.
Pay close attention to all warning and caution notices given in
this manual.
Select an installation location which is rigid and strong enough
to support or hold the unit, and select a location for easy
maintenance.
…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.
WARNING
This symbol refers to a hazard or unsafe
practice which can result in severe personal
injury or death.
CAUTION
Keep the fire alarm and the air outlet at least
1.5 m away from the unit.
CAUTION
This symbol refers to a hazard or unsafe
practice which can result in personal injury or
product or property damage.
…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.
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 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.
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.
…At least 2.5 m
Indoor unit of this room air conditioner shall be installed in a
height of at least 2.5 m.
SPECIAL PRECAUTIONS
WARNING
When Wiring
…In laundry rooms
Do not install in laundry rooms. Indoor unit is not drip proof.
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO WIRE
THIS SYSTEM.
When Connecting Refrigerant Tubing
WARNING
•
When performing piping work do not
mix air except for specified refrigerant
(R410A) in refrigeration cycle. It causes
capacity down, and risk of explosion
and injury due to high tension inside the
refrigerant cycle.
•
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.
•
Refrigerant gas leakage may cause fire.
•
Ventilate the room well, in the event that is refrigerant gas
leaks during the installation. Be careful not to allow contact
of the refrigerant gas with a flame as this will cause the
generation of poisonous gas.
•
Connect all wiring tightly. Loose wiring may cause overheating
at connection points and a possible fire hazard.
•
Keep all tubing runs as short as possible.
•
Provide a power outlet to be used exclusively for each unit.
•
Use the flare method for connecting tubing.
•
Provide a power outlet exclusively for each unit, and full
disconnection means having a contact separation in all poles
must be incorporated in the fixed wiring in accordance with the
wiring rules.
•
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 leak-free connection.
•
Check carefully for leaks before starting the test run.
•
Do not leak refrigerant while piping work for an installation or
re-installation, and while repairing refrigeration parts. Handle
liquid refrigerant carefully as it may cause frostbite.
•
To prevent possible hazards from insulation failure, the
unit must be grounded.
