Toshiba RAV-SM1101AT-E Precautions For Safety, New Refrigerant Air Conditioner Installation

RAV-SM561AT-E, RAV-SM801AT-E

1 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

New Refrigerant Air Conditioner Installation

•THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DE- STROY 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.

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.

The installation fuse (25A D type ) must be used for the power supply line of this conditioner.

WARNING

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

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 electric shock.

•Connect the connecting cable correctly.

If the connecting cable is connected in a wrong way, electric parts may be damaged.

•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 abnor- mally high and it may resultingly causes pipe burst and injuries on persons.

•Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.

•Exposure of unit to water or other moisture before installation may cause short-circuit of electrical parts.

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

•After unpacking the unit, examine it carefully if there are 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.
