• Check if the power plug is properly connected.
• Check whether the auxiliary power switch (MCCB, ELB) is turned on.
• If the auxiliary power switch (MCCB, ELB) is turned off, the air
conditioner does not work although you press the (Power) button.
• When you clean the air conditioner or do not use it for an extended
period of time, turn off the auxiliary power switch (MCCB, ELB).
• After the air conditioner is not used for an extended period of time, be
sure to turn on the auxiliary power switch (MCCB, ELB) 6 hours before
starting operation.
NOTE
• The auxiliary power switch (MCCB, ELB) is sold separately.
• Make sure that auxiliary power switch (MCCB, ELB) is installed in
the distribution box inside the building.
• If the air conditioner is turned off by the Timed off function, turn on the
air conditioner again by pressing the (Power) button.

• Check whether the outdoor unit is designed for cooling only. In this case,
warm air does not come out although you select the Heat mode.
• Check whether the remote control is designed only for cooling only. Use
a remote control that supports both cooling and heating.
The fan speed does

• Check whether the Auto or Dry mode is running. In these modes, the
air conditioner controls the fan speed automatically, and you cannot

Installation Procedure
Installation Procedure
Step 1 Installing the indoor unit
When deciding on the location of the air conditioner the
following restrictions must be taken into account.
1 Place the pattern sheet on the ceiling at the spot
where you want to install the indoor unit.
NOTE
• Since the diagram is made of paper, it may shrink
or stretch slightly due to temperature or humidity.
For this reason, before drilling the holes, be sure
to maintain the correct dimensions between the
markings.
2 Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.

3 Install the suspension bolts, depending on the ceiling
type.
Ceiling support
CAUTION
• Make sure that the ceiling is strong enough to support
the weight of the indoor unit. Before hanging the unit,
test the strength of each attached suspension bolt.
• If the length of the suspension bolt is more than 1.5 m,
