WARNING
.
CAUTION
Never use for special applications such as storing food, plants,
precision equipment or art.
The quality of these items may deteriorate.
Always provide adequate signal noise protection when installing in
facilities such as hospitals and communication stations.
Equipment at these facilities, such as inverters, in-house generators,
high-frequency medical equipment, two-way communication equipment,
may cause the air conditioner to operate improperly. Conversely, the
signal noise from the air conditioner may affect the operation of medical
equipment and two-way communication equipment and this could inter-
fere with the medical treatment being given a patient or cause distur-
bances or interference in video broadcasting equipment.
Never operate the air conditioner with the air filter removed.
Particles will enter into the air conditioner and cause damage.
Route wiring so that there is no tension.
Tension could cause the wire to break and this could result in excessive
heat or fire.
Dispose of packing materials properly.
Never use the unit in special environments.
Special environments with high concentrations of oil, steam or sulfuric
gases will reduce the performance of the air condition and cause its
parts to deteriorate.
Never turn off the power supply immediately after stopping the
unit.
Wait five minutes or more before turning off the power supply. Turning
off the power supply before that time could result in water leakage or
damage.
Never install the unit where run-off could result in damage.
If the humidity in the room exceeds 80% or if the drain becomes
clogged, water may drain off of the indoor unit. When the unit is used
for heating, there may be drainage from the outdoor unit. If required,
provide collector drain for the outdoor unit.
