Installation 171
1. Precautions
Be sure only trained and qualified service personnel to install, repair or service the equipment.
Improper installation, repair, and maintenance may result in electric shocks, short-circuit, leaks, fire or other
damage to the equipment.
If installation is defective, it will cause water leakage, electrical shock fire.
When installing the unit in a small room, take measures against to keep refrigerant concentration from
exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for
more information. Excessive refrigerant in a closed ambient can lead to oxygen deficiency.
Use the attached accessories parts and specified parts for installation.
Otherwise, it will cause the set to fall, water leakage, electrical shock fire.
Install at a strong and firm location which is able to withstand the set's weight.
If the strength is not enough or installation is not properly done, the set will drop to cause injury.
The appliance shall be installed in accordance with national wiring regulations
The appliance shall not be installed in the laundry.
Before obtaining access to terminals, all supply circuits must be disconnected.
The appliance must be positioned so that the plug is accessible.
The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the fluid flow.
For electrical work, follow the local national wiring standard, regulation and this installation instructions. An
independent circuit and single outlet must be used.
If electrical circuit capacity is not enough or defect in electrical work, it will cause electrical shock fire.
Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on
the terminal.
If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
Wiring routing must be properly arranged so that control board cover is fixed properly.
If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical
shock.
If the supply cord is damaged, it must be replaced by the manufacture or its service agent or similarly
qualified person in order to avoid a hazard.
An all-pole disconnection device which has at least 3mm separation distance in all pole and a residual
current device(RCD)with the rating of above 10mA shall be incorporated in the fixed wiring according to
the national rule.
When carrying out piping connection, take care not let air substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and
injury.
Do not modify the length of the power supply cord or use of extension cord, and do not share the single
outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling and causing accidents.
The temperature of refrigerant circuit will be high, please keep the interconnection cable away from the
copper tube.
The power cord type designation is H07RN-F. Equipment complying with IEC 61000-3-12.
If the refrigerant leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant comes into the place contacting with fire.
After completing the installation work, check that the refrigerant does not leak.
Toxic gas may be produced if the refrigerant leaks into the room and comes into contact with a source of fire,
such as a fan heater, stove or cooker.
