EKBRP2A81 : ABC I/P PRINTED CIRCUIT BOARD KIT
Position the wires so that the cover will not rise when wiring the power supply.
Make sure that the cover is attached securely. If the cover is attached improperly,
electric shocks or fire may result.
●The following two conventions are used to indicate and classify precautions in this manual.
Always read the important safety information provided with them.
●Make sure that the unit operates properly after completing the installation, and explain to the customer
how to operate the unit and keep it maintained.
Also, advise the customer that they should keep this installation manual along with other manual for
future reference.
●At the time of the installation, read the installation manual of the unit along with the electric diagram.
Ask your dealer or qualified personnel to carry out installation work.
Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage,
electric shocks or fire.
0P750596-1
Install the kit in accordance with the instructions in this installation manual.
Improper installation may result in electric shocks or fire.
CAUTION
READ THE INSTRUCTIONS PROVIDED HEREIN CAREFULLY IN ADVANCE AND INSTALL THIS KIT CORRECTLY.
Do not install this kit in the following locations:
１．Where there is a high concentration of mineral oil spray or vapor for example a kitchen.
２．Where corrosive gas, such as sulfurous acid gas, is produced, acid or alkaline steam gathers,
or the air contains a high salt content, such as places by the sea. Parts may be corroded and fall off.
３．Near machinery emitting electromagnetic waves or in places with great voltage fluctuations,
such as factories.
４．Where flammable gas may leak, in places with carbon fiber or ignitable dust suspensions in the air
or with volatile flammables such as paint thinner or gasoline, or in vehicles or vessels.
Fire may result if gas leakage occurs and stays around the kit.
５．Where small animals intrude, fallen leaves gather, or weeds grow.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire.
Turn off the unit before touching electrical parts.
An electric shock may be received if charged parts come in contact with humans.
Failure to observe these instructions properly may result in property damage or
personal injury, which may be serious depending on the circumstances.
Failure to follow these instructions properly may result in personal injury or loss of life.
WARNING
Be sure to use the specified wires and fix them securely so that no external force resulting from the wires
will be imposed on any terminal connections.
Improper connections or securing of wires may result in abnormal heat build-up or fire.
CAUTION
Make certain that all electrical work is carried out by qualified personnel according to the local laws and
regulations and this installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper electrical construction may lead to electric
shocks or fire.
WARNING
Be sure to use only the specified accessories and parts for the installation work.
Failure to use the specified parts may cause the kit to fail or result in electric shocks or fire.
