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.

1 PRECAUTIONS FOR SAFETY

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

•Important safety information are described 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.

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 in 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.

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 pipe work 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.
