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.
