SPECIAL PRECAUTIONS

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.

CAUTION

WARNING

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.

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.

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.

Install a protective leakage breaker depending on the

installation location (especially a damp or humid

location). If a leakage breaker is not installed, electric

shock can occur.

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 leak-free 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.
