Incorrect installation can result in falling equipment causing damage, injuries or other
accidents.
► Install in a location that is fully strong enough to support the weight of the equipment.
► Perform installation that is secure enough to withstand earthquakes, tornadoes, storms
and other strong winds.
Frostbite injuries may result from coming into direct contact with the refrigerant gas.
► When handling refrigerant gas, be careful not to touch the refrigerant gas directly.
CAUTION
The following precautions need to be followed strictly, in order to avoid hazardous situations, which
could result in minor or moderate injury.
Electric shock, shock and fires may result from incomplete grounding of the equipment or
failure to install an earth leakage circuit breaker (ELCB) or residual current device (RCD).
► Be sure to ground equipment properly.
► Do not attach ground wires to gas pipes, water pipes, lightning arresters, or telephone
ground lines.
► Always install an earth leakage circuit breaker or residual current device.
Ignition of flammable gas or inflammable materials may result from installing the system in
locations where flammable gas can generate, enter, build up, or leak.
► Do not install the system in locations where flammable gas can occur in any way.
► Do not install in locations where volatile inflammable materials are handled.
