Instructions for safe operation
WARNING
▪ Do NOT modify, disassemble,
remove, reinstall or repair the unit
yourself as incorrect dismantling or
installation may cause an electrical
shock or fire. Contact your dealer.
▪ In case of accidental refrigerant
leaks, make sure there are no naked
flames. The refrigerant itself is
entirely safe, non-toxic and mildly
flammable, but it will generate toxic
gas when it accidentally leaks into a
room where combustible air from fan
heaters, gas cookers, etc. is present.
Always have qualified service
personnel confirm that the point of
leakage has been repaired or
corrected before resuming operation.
CAUTION
This unit is equipped with electrically
powered safety measures, such as a
refrigerant leak detector. In order to be
effective, the unit must be electrically
powered at all times after installation,
except for short service periods.
CAUTION
▪ NEVER touch the internal parts of the
controller.
▪ Do NOT remove the front panel.
Some parts inside are dangerous to
touch and appliance problems may
happen. For checking and adjusting
the internal parts, contact your
dealer.
WARNING
This unit contains electrical and hot
parts.
WARNING
Before operating the unit, be sure the
installation has been carried out
correctly by an installer.
CAUTION
It is unhealthy to expose your body to
the air flow for a long time.
CAUTION
To avoid oxygen deficiency, ventilate
the room sufficiently if equipment with
burner is used together with the
system.
CAUTION
Do NOT operate the system when
using a room fumigation-type
insecticide. Chemicals could collect in
the unit, and endanger the health of
people who are hypersensitive to
chemicals.

NEVER expose little children, plants or
animals directly to the airflow.
WARNING
Do NOT place a flammable spray
bottle near the air conditioner and do
NOT use sprays near the unit. Doing

wrong ampere ratings or other wires
