1. Safety precautions

1.1. Before installation and electric work

Symbols used in the text

Warning:

Describes precautions that should be observed to prevent danger of injury or death to the user.

Caution:

Describes precautions that should be observed to prevent damage to the unit.

Symbols used in the illustrations

: Indicates an action that must be avoided. : Indicates that important instructions must be followed. : Indicates a part which must be grounded. : Beware of electric shock. (This symbol is displayed on the main unit label.)

<Color: yellow>

HIGH VOLTAGE WARNING:

• Control box houses high-voltage parts.

• When opening or closing the front panel of the control box, do not let it come into contact with any of the internal components.

• Before inspecting the inside of the control box, turn off the power, keep the unit off for at least 10 minutes, and confirm that the voltage between FT-P and FT-N on INV Board has dropped to DC20V or less. (It takes about 10 minutes to discharge electricity after the power supply is turned off.)

Warning:

• Ask the dealer or an authorized technician to install the air conditioner.

- Improper installation b y the user may result in water leakage, electric shock,

or fire.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

• Use the specified cables for wiring. Make the connections securely so that the outside force of the cable is not applied to the terminals.

- Inadequate connection and fastening may generate heat and cause a fire.

• Always use Relay Box and other accessories specified by Mitsubishi Electric.

- Ask an authorized tech nician to install the accessories. Improper inst allation

by the user may result in water leakage, electric shock, or fire.

• Never repair the unit. If the air conditioner must be repaired, consult the dealer.

- If the unit is repaired improperly, water leakage, electric shock, or fire may

result.

• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

• To reduce the risk of electric shock, do not install the unit when it is raining.

• Never attempt to repair the unit without the proper qualifications. If the air conditioner must be repaired consult the dealer, contractor or qualified Refrigeration Engineer.

- If the unit is repaired improperly, water leakage, electric shock, or fire may

result.

• Have all electric work done by a licensed electrician according to the “Electric Facility Engineering Standard”, the “Wire Regulations in each area” and the instructions given in this manual and always use a dedicated power supply.

- If the power source capacity is inadequat e or electric work is performed

improperly, electric shock and fire may result.

• Securely install the outdoor unit terminal cover (panel).

- If the terminal cover (panel ) i s not installed properly, dust or water may

enter the outdoor unit and fire or electric shock may result.

• When moving and reinstalling the air conditioner, consult the dealer or an authorized technician.

- If the air conditioner is installe d improperly, water leakage, electric shock, or

fire may result.

• Do not reconstruct or change the settings of the protection devices.

- If the pressure switch, thermal switch, fuse, or other protecti on device is

shorted or operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result.

• To dispose of this product, consult your dealer.

• The installer and system specialist shall secure safety against leakage according to local regulation or standards.

- Choose the appropriate wire size and the switch cap acities for the main

power supply described in this manual if local regulations are not available.

• Children should be supervised to ensure that they do not play with the appliance.

1.2.

Before installation

Caution:

• Do not use the air conditioner in special environments.

- Oil, steam, sulfuric smoke, etc. ca n significantly reduce the performance of

the air conditioner or damage its parts.

• When installing the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.

- Inverter equipment, privat e power g enera tor, high-frequency medical equip-

ment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

• To reduce the risk of injury, wear protective gear when working on the controller.

1.3. Before installation (relocation) -

electrical work

Caution:

• Ground the unit.

- Do not connect the ground wire to gas or water pipes, lightning rods, or tel-

ephone ground lines. Improper grounding may result in electric shock.

• Install the power cable so that tension is not applied to the cable.

- Tension may cause the cable to break and generate heat and cause a fire.

• Install a leak circuit breaker, as required.

- If a leak circuit breaker is not installed, elect ric shock may result.

• Use power line cables of sufficient current carrying capacity and rating.

- Cables that are too small may leak, generate heat, and cause a fire.

• Use only a circuit breaker and fuse of the specified capacity.

- A fuse or circuit breaker of a larger capacity, or the use of a substitute

simple steel or copper wire may result in a general unit failure or fire.

• Stop the operation and turn off the power before cleaning.

• Do not wash the air conditio ner units.

- Washing them may cause an electric shock.

 Before installing the unit, make sure you read all the “Safety

precautions”.

 The “Safety precautions” provide very important points

regarding safety. Make sure you follow them.

Warning:

Carefully read the labels affixed to the main unit.

• Be very careful about transporting the product.

- One person should not carry the product. Its weight is in excess of 20 kg [45 LBS].

- Some products u se PP bands for p ackaging. Do not use any PP bands as a means of transportation. It is dangerous.

• Safely dispose of the packing materials.

- Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

- Tear apart and throw away plastic packaging bags so that children will not play with them. If children play with a plastic bag which has not been torn apart, they face the risk of suffocation.

• Never connect in reverse phases.

• Install the power cable so that tension is not applied to the cable.

• Do not wash the air conditioner units.

1.4. Before starting the test run

Caution:

• Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch can result in irreversible damage to internal parts. Keep the power switch turned on during the operational season. Make sure of the phase order of power supply and voltage between each phase.

• Do not touch the switches with wet fingers.

- Touching a switch with wet fingers can result in an electric shock.

• Do not touch the refrigerant pipes during and immediately after operation.

- During and immediately after operation, the refrigerant pipes may be hot or

cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigeran t cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.

• Do not operate the air conditioner with the panels and guards removed.

- Rotating, hot, or high-voltage parts can cause injuries.

• Do not turn off the power immediately after stopping operation.

- Always wait at least 5 minutes before turning off the power. Otherwise,

drainage water leakage or mechanical failure of sensitive parts may occur.
