PRECAUTIONS FOR SAFETY

• Ensure that all Local, National and International regulations are satisfied.
• Read this "PRECAUTIONS FOR SAFETY" carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• 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 the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner's Manual.
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 refrigerat-
ing 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.
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.
The installation fuse must be used for the power supply line of this air conditioner.
• 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.
