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 (test run) 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.
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 earth 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 main power supply switch or breaker before attempting any electrical work.
Make sure all power switches 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 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.
• 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.
