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 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.

 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

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 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.

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 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.

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 floors.

...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.

When Connecting Refrigerant Tubing

•  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 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 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.

•  After installation, explain correct operation to the customer, using the operating 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 5 minutes before 

touching electrical components.

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

comes in contact with a flame, it produces a toxic gas.

 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.

Always use a separate power supply line protected by a circuit breaker operating on all 

wires with a distance between contact of 1/8 in. (3 mm) for this unit.

The unit must be correctly earthed (grounded) and the supply line must be equipped 

with a differential breaker in order to protect the persons.

The units are not explosion proof and therefore should not be installed in explosive 

atmosphere.

When moving, consult authorized service personnel for disconnection and installation 

of the unit.

Do not place any other electrical products or household belongings under indoor unit or 

outdoor unit. 

Dripping condensation from the unit might get them wet, and may cause damage or 

malfunction of your property.

• Installation must be performed in accordance with the requirement of NEC and CEC by 

authorized personnel only.

For authorized service personnel only.
