1. SAFETY PRECAUTIONS

1.1. 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 efﬁ ciently.

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.

WARNING

This symbol refers to a hazard or unsafe practice which can

result in severe personal injury or death.

CAUTION

This symbol refers to a hazard or unsafe practice which can

result in personal injury and the potential for product or prop-

erty damage.

• Hazard alerting symbols

Electrical

Safety/alert

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 certiﬁ ed

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.

1.2. Special precautions

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A

QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYS-

TEM.

• 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 wir-

ing diagram and these instructions when wiring. Improper connections and inadequate

earthing (grounding) can cause accidental injury or death.

• Earth (Ground) the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points and

a possible ﬁ re 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 ﬁ ns on the air conditioner can cut your ﬁ ngers.

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 drip-

ping and water damage to walls and ﬂ oors.

...In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable air bafﬂ e.

...In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow.

When Connecting Refrigerant Tubing

• Keep all tubing runs as short as possible.

• Use the ﬂ are method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the ﬂ are and union tubes before

connecting them, then tighten the nut with a torque wrench for a leak-free connection.

• Check carefully for leaks before opening the refrigerant valves.

When Servicing

• Turn the power OFF at the main circuit breaker panel before opening the unit to check

or repair electrical parts and wiring.

• Keep your ﬁ ngers and clothing away from any moving parts.

• Clean up the site after you ﬁ nish, remembering to check that no metal scraps or bits of

wiring have been left inside the unit being serviced.

• After installation, explain correct operation to the customer, using the operation manual.

WARNING

• Never touch electrical components immediately after the power supply has been

turned off. Electric shock may occur. After turning off the power, always wait 10 min-

utes before touching electrical components.

• If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant

comes in contact with a ﬂ ame, it produces a toxic gas.

• Cancer and Reproductive Harm - www.P65Warnings.ca.gov.

• Branch box which is speciﬁ ed in this manual is the equipment to support the indoor unit

of multi-connection type.

• All products are manufactured to metric units and tolerances. United States customary

units are provided for reference only. In cases where exact dimensions and tolerances

are required, always refer to metric units.

For authorized service personnel only.

CAUTION • Do not attempt to install the air conditioner or a part of the air conditioner by yourself. • This unit must be installed by qualified personnel with a capacity certificate for handling refrigerant fluids. Refer to regulation and laws in use on installation place. • This unit is part of a set constituting an air conditioner. It must not be installed alone or with a device non-authorized by the manufacturer.

.1. Selecting an installation location CAUTION Install heat insulation around both the gas and liquid pipes. Failure to do so may cause water leaks. Use heat insulation with heat resistance above 248 °F (120 °C). Reverse cycle model only. In addition, if the humidity level at the installation location of the refrigerant piping is expected to exceed 70%, install heat insulation around the refrigerant piping. If the expected humidity level is 70-80%, use heat insulation that is 3/4 in.
