In Case of Improper Installation
When Wiring
ELECTRICAL SHOCK CAN CAUS
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM. E
• 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 sys-
tem. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inad-
equate grounding can cause
accidental injury or death.
•
When Installing…
…In a Room
Properly insulate any tubing run inside a room to preven
“sweating” that can cause dripping and water damage to
walls and floors. t
…In Moist or Uneven Locations
…
…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.
•
• Keep all tubing runs as short as possible.
• 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 leak-free con-
nection.
• Check carefully for leaks before starting the test run.
When Servicing
•
• Keep your fingers and clothing away from any moving
parts.
•
•
• Confirm after installation that no refrigerant gas is leak-
ing. If the gas comes in contact with a burning stove,
gas water heater, electric room heater or other heat
source, it can cause the generation of poisonous gas.
IMPORTANT!
For safe installation and trouble-free operation, you must:
Pay close attention to all warning and caution notices
given in this manual.

WARNING
CAUTION
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.
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including fail-
ure to follow the instructions in this document.
SPECIAL PRECAUTIONS
WARNING
Ground the unit following local electrical codes.
Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
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.
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.
When Connecting Refrigerant Tubing
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.
Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical parts
and wiring.
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.
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.
