Checking before use
Tips on using air conditioner
Here are some tips that you would follow when using your air conditioner.
TOPIC
RECOMMENDATION
Cooling
•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.
Heating
•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
insufficiently heats, using an additional heating appliance in
combination with the air conditioner is recommended.
Frost & De-ice
•When the air conditioner runs in Heat mode, due to temperature
difference 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
•Fan may not operate for about 3~5 minutes at the beginning to
prevent any cold blasts while the air conditioner is warming up.
High indoor/
outdoor
temperatures
•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.
Power failure
•If a power failure occurs during the operation of the air conditioner,
the operating immediately stops and unit will be off. When power
returns, the air conditioner will run automatically.
Protection
mechanism
•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.

Indoor unit installation
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.
• 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.
Concrete
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.
Insert
Hole in anchor
hole in plug
Suspension bolt(M8)-field supply
•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.
4
Ceiling support
Screw eight nuts to the suspension bolts making space for hanging
the indoor unit.
•You must install all the suspension rods.
5
Hang the indoor unit to the suspension bolts between two nuts.
•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.
6
Screw the nuts to suspend the unit.
7
Adjust level of the unit by using measurement plate for all 4 sides.
•For proper drainage of condensate, give a "A"mm slant to the
left or right side of the unit which will be connected with the
drain hose, as shown in the figure. Make a tilt when you wish to
install the drain pump, too.
•When installing the indoor unit, make sure it is not tilted toward
front or back side.
When the drain hose is installed to the right.

Purging the unit
From factory the unit is supplied and set with a pre-charge of nitrogen gas. (insert gas) Therefore, all insert gas must be purged
before connecting the assembly piping.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result : All inert gas escapes from the indoor unit.
Gas refrigerant port
Liquid refrigerant port
• T o prevent dirt or foreign objects from getting into the pipes during
installation, do NOT remove the pinch pipe completely until you are
ready to connect the piping.
• Connect the indoor and outdoor units using pipes with flared
connections(not supplied). For the lines, use insulated, unwelded,
degreased and deoxidized copper pipe (Cu DHP type to ISO 1337 or
UNI EN 12735-1), suitable for operating pressures of at least 4200kPa
and for a burst pressure of at least 20700kPa. Copper pipe for hydrosanitary applications is completely unsuitable.
• For sizing and limits (height difference, line length, max. bends,
refrigerant charge, etc.) see the outdoor unit installation manual.
• All refrigerant connection must be accessible, in order to permit either
unit maintenance or removing it completely.
27
Connecting the refrigerant pipe
There are two refrigerant pipes of different diameters :
◆ A smaller one for the liquid refrigerant
◆ A larger one for the gas refrigerant
◆ The inside of copper pipe must be clean & has no dust
1. Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually
and then with a torque wrench, a spanner applying the following torque.

• If the pipes must be shortened refer to page 14.
2. Must use insulator which is thick enough to cover the refrigerant tube to protect the condensate water on the outside
of pipe falling onto the floor and the efficiency of the unit will be better.
3. Cut off any excess foam insulation.
4. Be sure that there must be no crack or wave on the bended area.
5. It would be necessary to double the insulation thickness(10mm or more) to prevent condensation even on the
insulator when if the installed area is warm and humid.
6. Do not use joints or extensions for the pipes that connect the indoor and outdoor unit. The only permitted connections
are those for which the units are designed.

Cutting/Flaring the pipes
1. Make sure that you have the required tools available. (pipe cutter, reamer, flaring tool and pipe holder)
2. If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle
with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.

Performing leak test & insulation
Leak test
◆ LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R410A, it’s responsable
of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer)
at a pressure above 40 bar (gauge).
◆ LEAK TEST WITH R410A (after opening valves)
Before opening valves, discharge all the nitrogen into the system and create vacuum. After opening valves check
leaks using a leak detector for refrigerant R410A.
• Discharge all the nitrogen to create a vacuum and charge the system.
Insulation
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
1 To avoid condensation problems, place T13.0 or thicker Acrylonitrile Butadien Rubber separately around each refrigerant
pipe.
No gap
• Always make the seam of pipes face upwards.
NBR(T13.0 or thicker)
2 Wind insulating tape around the pipes and drain hose avoiding to compress
the insulation too much.
3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor
unit.
4 The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be fixed to the wall with suitable ducts.
• A
ll refrigerant connection must be accessible, in order to permit
either unit maintenance or removing it completely.
