Here are some tips that you would follow when using your air conditioner.
TOPIC RECOMMENDATION
 • If current outside temperatures are much higher than the selected indoor
temperature, it may take time to bring the inner temperature to the desired coolness.
• Avoid drastically turning down the temperature.
Energy is wasted and the room does not cool faster.
 • Since the air conditioner heats the room by taking heat energy from outdoor air, the
heating capacity may decrease when outdoor temperatures are extremely low. If you
feel the air conditioner insuciently heats, using an additional heating appliance in
combination with the air conditioner is recommended.
 • When the air conditioner runs in Heat mode, due to temperature dierence between
the unit and the outside air, frost will form.
If this happens:
- The air conditioner stops heating.
- The air conditioner will operate automatically in De-ice mode for
10 minutes.
- The steam produced on the outdoor unit in De-ice mode is safe.
No intervention is required; after about 10 minutes, the air conditioner operates again
normally.
The unit will not operate when it starts to de-ice.
 • Fan may not operate for about 3~5 minutes at the beginning to prevent any cold
blasts while the air conditioner is warming up.


• If both indoor and outdoor temperatures are high and the air conditioner is running in
Heat mode, the outdoor unit’s fan and compressor may stop at times. This is normal; wait
until the air conditioner turns on again.
 • If a power failure occurs during the operation of the air conditioner, the operating
immediately stops and unit will be o. When power returns, the air conditioner will run
automatically.
 • If the air conditioner has just been turned on after operation stops or being plugged
in, cool/warm air does not come out for 3 minutes to protect the compressor of the
outdoor unit.

For the best performance from your air conditioner, clean it periodically. When cleaning, make sure to unplug from the unit
for user’s safety.

When deciding on the location of the air conditioner with the owner, 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.
2
Insert bolt anchors. Use existing ceiling supports or construct a suit-
able support as shown in figure.
3 Install the suspension bolts depending on the ceiling type.
4 Screw eight nuts to the suspension bolts making space for hanging
the indoor unit.
5 Hang the indoor unit to the suspension bolts between two nuts.
6 Screw the nuts to suspend the unit.
7 Adjust level of the unit by using measurement plate for all 4 sides.

• 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 maintain the correct
dimensions between the markings.
•Ensure 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 suspension bolt is more than 1.5m,
it is required to prevent vibration.
• If this is not possible, create an opening on the false ceiling in
order to be able to use it to perform the required operations on
the indoor unit.
• Piping must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
piping into position for connection to the unit before
placing the unit inside the ceiling.
•For proper drainage of condensate, give a 3mm slant to the
left or right side of the unit which will be connected with the
drain hose, as shown in the gure. Make a tilt when you wish to
install the drain pump, too.
• You must install all the suspension rods.
