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.

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 charged 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. Moreover, do not use the existing piping because there are problems with pressure-resistance force

and impurity in it.

• Be sure to install an earth leakage breaker that is not tripped by shock waves.

If an earth leakage breaker is not installed, an electric shock may be caused.

• Be sure to use the cord clamps attached to the product.

• Do not damage or scratch the conductive core and inner insulator of power and inter-connecting cables when

peeling them.

• Be sure to comply with local regulations on running the wire from outdoor unit to indoor unit (size of wire and

wiring method etc.)

• Use the power cord and Inter-connecting cable of specified thickness, type, and protective devices required.

REQUIREMENT

• For power supply wiring, strictly conform to the Local Regulation in each country.

• For wiring of power supply of the outdoor units, follow the Installation Manual of each outdoor unit.

• Never connect 220 – 240V power to the terminal blocks (A, B, etc.) for control wiring.

(Otherwise, the system will fail.)

• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.

The coating may melt resulting in an accident.

• After connecting cables to the terminal blocks, provide a trap and fix cables with the cable clamp.

• Run the refrigerant piping line and control wiring line in the same line.

• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.
