Unit Installation
If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or
electrical shock.
(14) 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.
(15) An all-pole disconnection switch having a contract separation of at least 3mm in poles should be
connected in fixed wiring.
(16) When carrying out piping connection, take care not to let air substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and
injury.
(17) 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.
(18) 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.
Remark: Failure to observe a warning may result in death.
1.4.8 Caution
(1) Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning rod or a telephone ground wire.
Incomplete grounding may result in electric shocks.
(2) Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks.
(3) Connect the outdoor unit wires, and then connect the indoor unit wires.
You are not allowed to connect the air conditioner with the power source until wiring and piping the air
conditioner is done.
(4) While following the instructions in this installation manual, install drain piping in order to ensure
proper drainage and insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and property damage.
(5) Install the indoor and outdoor units, power supply wiring and connecting wires at least 1 meter away
from televisions or radios in order to prevent image interference or noise.
Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the
noise.

children should be supervised to ensure that they do not play with the appliance.
(7) Don't install the air conditioner in the following locations:
There is petrolatum existing.
There is salty air surrounding (near the coast).
There is caustic gas (the sulfide, for example) existing in the air (near a hot spring).
The Volt vibrates violently (in the factories).
In buses or cabinets.
In kitchen where it is full of oil gas.
There is strong electromagnetic wave existing.
There are inflammable materials or gas.
There is acid or alkaline liquid evaporating.
Other special conditions.
(8) The insulation of the metal parts of the building and the air conditioner should comply with the
