To install a unit that uses R410A refrigerant, use dedicated tools and piping mate-
CAUTION!
rials that have been manufactured specifically for R410A use. Because the pres-
sure of R410A refrigerant is approximately 1.6 times higher than the R22, failure to
use dedicated piping material or improper installation can cause rupture or injury.
Furthermore, it can cause serious accidents such as 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. Children should be supervised to ensure that they do not play with the appliance.
When the thunder sounds and the lightning malfunction strike, do not touch the outdoor unit.
If the lightning strike, it can cause malfunction or electric shock.
Do not place other electric appliance or furniture under the outdoor unit and under the outlet
port of indoor unit. The water may drop and can cause the taint damage or fault.
Keep clean and do not place the things around the outdoor unit. If covered with fallen leaves,
it can cause the fault by the small animals or insects coming into and touch the internal elec-
tric parts.
Do not stand on unstable steps when operating or cleaning the air conditioner. It may over-
turn and can cause the injury.
Does not install the indoor unit and the outdoor unit in the following areas:
Area with high salt content, such as at the seaside. It will deteriorate metal parts, causing
the parts to fail or the unit to leak water.
Area filled with mineral oil or containing a large amount of splashed oil or steam, such as a
kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.
Area that generates substances that adversely affect the equipment, such as sulfuric gas,
chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to corrode,
which can cause refrigerant leakage.
Area containing equipment that generates electromagnetic interference. It will cause the
control system to malfunction, preventing the unit from operating normally.
Area that can cause combustible gas to leak, contains suspended carbon fibers or flamma-
ble dust, or volatile inflammables such as paint thinner or gasoline. If gas leaks and settles
around the unit, it can cause a fire.
Area where small animals may live. It may cause failure, smoke or fire if small animals enter
and touch internal electrical parts.
Area where animals may urinate on the unit or ammonia may be generated.
