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.

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 ground-
ing can cause accidental injury or death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheat-
ing 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.
Important
CAUTION
When Installing
……………………………………………………………………
…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 Sys-tems)
Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
……………………………………………………………………
• Ventilate the room well, in the event that 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.
• 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 connection.
• Check carefully for leaks before starting the test run.
NOTE
Depending on the system type, liquid and gas lines may be
either narrow or wide. Therefore, to avoid confusion the
refrigerant tubing for your particular model is specified as either
“narrow” or “wide” rather than as “liquid” or “gas”.
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 when installation is finished. Check that no
metal scraps or bits of wiring have been left inside the unit.
CAUTION
• Ventilate any enclosed areas when installing or testing the
refrigeration system. Contact of refrigerant gas with fire or
heat can produce poisonous gas.
• Confirm after installation that no refrigerant gas is leaking. 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.
