Refrigerant piping

• Piping material used for the conventional refrigerant cannot be used.

• Use copper pipe only with a wall thickness of 0.8 mm or more for Ø6.4, Ø9.5, Ø12.7.

• Flare nut and flare operations are also different from those of the conventional refrigerant. Use the flare nut fitted to the indoor unit of the air conditioner.

• Ensure that all Local, National and International regulations are satisfied.

• Important safety information are describes in this installation manual. Please ensure this manual is read thoroughly and kept for future reference.

• After the installation work, perform a trial operation to check for any problem. Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.

• Turn off the main power supply switch (or breaker) before any unit maintenance.

• Ask the customer to keep the Installation Manual together with the Owner’s Manual.

PRECAUTIONS FOR SAFETY

CAUTION New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER FEATURES A NEW HFC REFRIGERANT (R410A) WHICH DOES NOT

DEPLETE OZONE LAYER.

The pressure of R410A is 1.6 times higher than that of former refrigerant R22. The refrigerating oil has also been changed. Therefore be sure that any former refrigerant, refrigerant oil or any other contaminants do not enter the refrigerating cycle of the air conditioner, during either installation or service work. If incorrect tools or operating procedures are used, there is a possibility of a serious accident. Use only tools and materials that have been designed to operate with R410A.

To prevent the risk of charging with an incorrect refrigerant, the dimensions of the charging port connections are different to those used for conventional refrigerant. Therefore only tools designed to operate with R410A can be used.

For connecting pipes, use piping specifically designed for R410A. During installation, ensure pipes are clean and ensure contaminants do not enter the pipes as the system is affected

by impurities such as water, oxide scales, dirt, oil, etc. Do not use existing pipe work from previous installation as this will cause problems due to pressure resistances and impurities within the pipe.

ENGLISH

CAUTION To Disconnect the Appliance from Main Power Supply.

This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

WARNING

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

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

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause an electric shock.

• Connect all of the installation wiring correctly.

If the installation wiring is incorrect electrical parts may be damaged.

• During the transportation and installation of the air conditioning unit, ensure that gaseous matter

other than the specified refrigerant does not enter into the refrigeration cycle.

If a refrigerant becomes contaminated with foreign gases, the gas pressure within the refrigerant cycle will become abnormally high and may result in the fracture of pipework and possible human injury.

• Do not modify this unit by removing any of the safety guards or by overriding any of the safety

interlock switches.

• Exposure of the unit to water or other forms of moisture before installation may cause a short-circuit

of the electrical parts.

Do not store it in a wet basement or expose to rain or water.

• After unpacking the unit, examine for possible damage.

• Do not install in a place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• 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 in

the event of a refrigerant leak the rooms does not exceed the critical level.

PRECAUTIONS FOR SAFETY

• Install the air conditioner securely in a location where the base can sustain the weight of the unit

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 unit falling.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gases may be generated.

• 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 gases maybe generated.

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

Manual. Ensure the power supply to the air conditioner is exclusive to that unit only.

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

• Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed,

so preventing any external forces having a negative effect on the terminals.

• Conform to the regulations of the local electric authority when wiring the power supply.

Inappropriate grounding may cause an electric shock.

• Do not install the air conditioner in a location that maybe subjected to a risk of exposure to a

combustible gas.

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

SELECTION OF INSTALLATION PLACE

WARNING

• The air conditioner must be installed in a location that can support the weight of the unit effectively.

If the unit is not installed on a foundation that can support its weight effectively, the unit may fall down, resulting in possible human injury.

• Where required ensure that the units installation is sufficient enough to withstand against an earthquake.

An insufficient installation could result in the unit falling, causing possible human injury.

• Install the air conditioner at a minimum height of 2.5 m from the floor.

Do not insert your hands or others into the unit while the air conditioner is operating.

CAUTION

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

• A place where the unit can be installed horizontally.

• A place where a sufficient servicing space can be maintained for safety maintenance and unit check.

• A place where the drain water can be exited from the unit, without causing a problem.

Avoid installing in the following places.

• Places exposed to air with a high salt content (seaside area), or places exposed to large quantities of sulfide gas

(hot spring). (Should the unit be used in these places, special protective measures are needed.)

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

• Places where organic solvent is used nearby.

• Places close to a machine generating high frequency.

• Places where the discharged air blows directly into the window of the neighbouring house. (For outdoor unit)

• Places where the noise from the outdoor unit can be easily transmitted to the neighboring property.

(When installing the air conditioner on the boundary with a neighbour, pay due attention to the level of noise.)
