࡛ Checkwhetherthe auxiliarypowerswitch (MCCB, ELB) isturned on.
࡛ If the auxiliarypowerswitch (MCCB, ELB) is turned off, the air
conditionerdoes notwork althoughyou pressthe (Power) button.
࡛ Whenyou clean the airconditionerordo not use it foran extended
period of time,turn off the auxiliarypowerswitch (MCCB, ELB).
࡛ Afterthe airconditioneris not used foran extended period of time, be
sureto turn onthe auxiliary powerswitch (MCCB, ELB) 6 hours before
starting operation.
NOTE
࡛ The auxiliary powerswitch (MCCB, ELB) is sold separately.
࡛ Make sure that auxiliarypowerswitch (MCCB, ELB) is installed in
the distribution box insidethe building.
࡛ If the airconditioneris turned off bythe Timed off function, turn on the

࡛ Checkwhetherthe outdoorunit is designed forcooling only. In this case,
warm airdoes not come out althoughyou select the Heat mode.
࡛ Checkwhetherthe remote control is designed onlyforcooling only. Use
a remote control that supports both cooling and heating.
The fan speed does
