WARNING
• Have the air conditioner ser-
viced by a qualified service
personnel. If it is serviced by
an unqualied person, he/she
can be injured by the refrigerant
under high pressure.
CAUTION
• The A/C system is charged
with new refrigerant that does
not destroy the ozone layer. Be
careful when servicing the A/C
system.
• Do not use unspecied refriger-
ant and compressor oil, or the
air conditioner system could be
seriously damaged.
• The performance of the A/C
becomes poor when the refrig-
erant is insu󰀩cient. However,
charging the air conditioner
with excessive refrigerant af-
fects its performance negative-
ly. Therefore, have the system
checked by a KIOTI Dealer if
malfunction is found.
