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.
