2 PRECAUTIONS FOR SAFETY

Installing, starting up, and servicing air--conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service mechanics should install, start--up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning heat exchanger. All other operations should be performed by trained service personnel. When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment. Follow all safety codes.Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment. Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize safety information. This is the safety--alert symbol . When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury.Understand these signal words: DANGER, WARNING, and CAUTION. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

WARNING

• Ask an authorized dealer or qualified installation professional to install (including moving)/maintain the air conditioner.

Inappropriate installation may result in water leakage, electric shock or fire.

• Be sure to connect ground wire. (grounding work) Incomplete grounding cause an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.

• Turn off the circuit breaker before attempting any electrical work. Make sure all circuit breaker is off. Failure to do so may cause electric shock.

• Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the air conditioner is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.

• When moving the air conditioner for the installation into another place, be very careful not to enter any

gaseous matter other than the specified refrigerant into the refrigeration cycle.

If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high and it resultingly causes pipe burst and injuries on persons.

• Perform installation work properly according to the Installation Manual. Inappropriate installation may result in water leakage, electric shock or fire.

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that the

concentration of refrigerant leakage occur in the room does not exceed the critical level.

• Install the air conditioner securely in a location where the base can sustain the weight adequately.

• Perform the specified installation work to guard against an earthquake. If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

• After the installation work, confirm that refrigerant gas does not leak. If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might generate.

• Electrical work must be performed by a qualified electrician in accordance with the Installation Manual. Make

sure the air conditioner uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

• Use the specified wires for wiring connect the terminals securely fix.

To prevent external forces applied to the terminals from affecting the terminals.

3-EN

–3–

Under Ceiling Type

• Conform to the regulations of the local electric company when wiring the power supply. Inappropriate grounding may cause electric shock.

• For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the

compressor before disconnecting the refrigerant pipe.

If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.

Installation Manual

CAUTION

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER.

• The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main unit and installation tools are changed from those for the conventional refrigerant.

• Accordingly the exclusive tools are required for the new refrigerant (R410A).

• For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not enter.

• Tighten the flare nut with a torque wrench in the specified manner. Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.

• Wear heavy gloves during the installation work to avoid injury.

• The installation fuse must be used for the power supply line of this conditioner.

3 SELECTION OF INSTALLATION PLACE

WARNING

• Install the air conditioner at enough strong place to withstand the weight of the unit.

If the strength is not enough, the unit may fall down resulting in injury.

• Install the air conditioner at a height 8’ (2.4 m) or

more from the floor.

If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you may contact with revolving fan or active electricity.

CAUTION

• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.

If a combustible gas leaks and stays around the unit, a fire may occur.

Upon approval of the customer, install the air conditioner in a place that satisfies the following conditions.

• Place where the unit can be installed horizontally.

• Place where a sufficient servicing space can be ensured for safety maintenance and check.

• Place where drained water will not cause any problem.

Avoid installing in the following places.

• Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas (hot spring). (Should the unit be used in these places, special protective measures are needed.)

• Place exposed to oil, vapor, oil smoke or corrosive gas.

• Place where organic solvent is used nearby.

• Place close to a machine generating high frequency.

• Place where the discharged air blows directly into the window of the neighbor house. (Outdoor unit)

• Place where noise of the outdoor unit is easily transmitted. (When install the outdoor unit on the boundary with the neighbor, pay due attention to the level of noise.)

• Place with poor ventilation. (Before air ducting work, check whether value of fan speed, static pressure and duct resistance are correct.)

 Height of ceiling

Set the installable height of the ceiling within 13’1” (4 m), otherwise the air distribution will become poor.

If height of ceiling exceeds 11’6” (3.5 m), hot air becomes difficult to reach the floor surface, and then the change of setup of high ceiling is necessary. For the change method of high ceiling, refer to the application control, “In case of installation to high ceiling” and “In case of incorporating filter sold separately” in this Manual.

According to the conditions of installation, setup time of turning-on of filter sign (notification of filter cleaning) of the remote control can be changed.

When it is difficult to warm up the room due to installation place or structure of the room, the detection temperature of heating can be raised. For change the setup time, refer to the application control, “Change of filter sign turning-on time” and “How to increase the heating effect” in this Manual.
