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 structure s , 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 coils. 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 and leakage breaker before attempting any electrical work. Make sure all circuit breaker and leakage breaker are 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 over pressurized, 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 refr igeration 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 conn ect the terminals securely fix.

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

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

• For the refrigerant pump-down 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 over pressurized, which may cause a burst or injury.

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.

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

• 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 and a long sleeve shirt during the installation work to avoid injury.

9 REFRIGERANT PIPING

 Refrigerant Piping

1. Use copper pipe with 0.03” (0.8 mm) or more thickness. (In case pipe size is dia.

5/8” (15.9 mm), with 0.04” (1.0 mm) or more.)

2. Flare nut and flare works are also different from those of the conventional refrigerant. Take out the flare nut attached to the main unit of the air conditioner, and use it.

REQUIREMENT

When the refrigerant pipe is long, provide support brackets at intervals of 8’2” - 9’10” (2.5 - 3 m) to clamp the refrigerant pipe. Otherwise, abnormal sound may be generated.

CAUTION

IMPORTANT 4 POINTS FOR PIPING WORK

1. Remove dust and moisture from the inside of the connecting pipes.

2. Tight connection (between pipes and unit)

3. Evacuate the air in the connecting pipes using VACUUM PUMP.

4. Check the gas leakage. (Connected points)

 Pipe size

 Permissible Piping Length and

Height Difference

They vary according to the outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit.

Flaring

• Cut the pipe with a pipe cutter. Remove burrs completely. Remaining burrs may cause gas leakage.

• Insert a flare nut into the pipe, and flare the pipe. As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newl y manufactured for R410A are recommended. However, the conventional tools can be used by adjusting projection margin of the copper pipe.

▼ Projection margin in flaring: B (Unit: in (mm))

Rigid (Clutch type)

▼ Flaring dia. meter size: A (Unit: in (mm))

* In case of flaring for R410A with the

conventional flare tool, pull it out approx.

0.02” (0.5 mm) more than that for R22 to adjust to the specified flare size. The copper pipe gauge is useful for adjusting projection margin size.

Piping with outdoor unit

• Shape of valve differs according to the outdoor unit. For details of installation, refer to the Installation Manual of the outdoor unit.

Heat insulation

Heat insulation for the pipes should be done separately for the liquid side and gas side. Because both of the liquid and gas side pipes become a low temperature during cooling operation, sufficient heat insulation should be done to prevent condensation.

• Heat insulator with a heat resistance of 248 °F (120 °C) or more must be used for the gas side pipe.

• The pipe connection section of the indoor unit must be heat insulated securely and compactly with the attached heat insulator.

 Air purge

Using a vacuum pump, perform vacuuming fr om the charge port of valve of the outdoor unit. For details, follow to the Installation Manual attached to the outdoor unit.

• Never use the refrigerant sealed in the outdoor unit for air purge.

REQUIREMENT

For the tools such as charge hose, etc., use those manufactured exclusively for R410A.

Refrigerant amount to be added

For addition of the refrigerant, add refrigerant “R410A” referring to the attached Installation Manual of outdoor unit. Be sure to use a scale to charge the refrigerant of specified amount.

REQUIREMENT

• Charging an excessive or too little amount of refrigerant causes a trouble of the compressor. Be sure to charge the refrigerant of specified amount.

• A personnel who charged the refrigerant should write down the pipe length and the added refrigerant amount in the nameplate attached to the service panel of the outdoor unit. It is necessary to troubleshoot the compressor and refrigeration cycle malfunction.
