Solution
The air is not cool or
warm enough.
࡛ Close the windows and doors to maximize the cooling and heating
efficiencies.
࡛ If the Cool mode is stopped and then started immediately, cool air comes
out after about 3 minutes to protect the compressor of the outdoor unit.
࡛ When the Heat mode is started, warm air does not come out
immediately to prevent cool air from coming out at the beginning.
࡛ If the refrigerant pipe is too long, the cooling and heating efficiencies
may be decreased. Avoid exceeding the maximum pipe length.
The air conditioner
makes strange
noises.
࡛ In certain conditions (especially, when the outdoor temperature is
lower than 20°C), a hissing, rumbling, or splashing sound may be heard
while the refrigerant is circulating through the air conditioner. This is a
normal operation.

is a normal sound.
Unpleasant odours
permeate the room.
࡛ If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
࡛ If both indoor temperature and indoor humidity are high, operate the air
conditioner in the Clean or Fan mode for 1 to 2 hours.
࡛ If the air conditioner has not been operated for an extended period of
time, clean the indoor unit and then operate the air conditioner in the
Fan mode for 3 to 4 hours to dry the inside of the indoor unit for removal
of unpleasant odours.
࡛ If the air filter blocked with dirt, clean the air filter.
Steam is produced
on the indoor unit.
࡛ In winter, if the indoor humidity is high, steam may be produced around
the air outlet while the defrost function is running. This is a normal
operation.
The outdoor unit
fan continues to
operate when the
air conditioner is
turned off.
࡛ W hen the air conditioner is turned off, the outdoor unit fan may
continue to operate to reduce noise of the refrigerant gas. This is a
normal operation.
Water drops
from the piping
connections of the
outdoor unit.
࡛ Condensation may develop due to the difference in temperature. This is
a normal condition.
Steam is produced
on the outdoor unit.
࡛ In winter, when the air conditioner runs in the Heat mode, the frost on
the heat exchanger melts and steam may be produced. This is a normal
operation, neither product malfunction nor a fire.

Step 7 Connecting the assembly pipes
to the refrigerant pipes
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 and 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.
NOTE
࡛ If the pipes must be shortened, see Step 6 Cutting
and flaring the pipes on page 28.
2 Be sure to use an insulator thick enough to cover the
refrigerant tube to protect the condensate water on
the outside of the pipe falling onto the floor and to
improve the efficiency of the unit.
3 Cut off any excess foam insulation.
4 Make sure that there are no cracks or waves on the
bent area.
5 It would be necessary to double the insulation
thickness (10 mm or more) to prevent condensation
even on the insulator when if the installed area is
warm and humid.

and for a burst pressure of at least 20.7 MPa. Copper
pipe for hydro-sanitary applications is completely
unsuitable.
Installation Procedure
Step 8 Performing the gas leak test
To identify potential gas leaks on the indoor unit, inspect
the connection area of each refrigerant pipe using a leak
detector for R-410A.
Before recreating the vacuum and recirculating the
refrigerant gas, pressurize the whole system with
nitrogen (using a cylinder with a pressure reducer) at a
pressure above 4.1 MPa in order to immediately detect
leaks on the refrigerant fittings.
4 The pipes and electrical cables connecting the indoor
unit with the outdoor unit must be fixed to the wall
with suitable ducts.

system, you can insulate the piping and hose.
1 To avoid condensation problems, place Acrylonitrile
Butadien Rubber separately around each refrigerant
pipe.

insulation thickness that must differ according to the
pipe size.
࡛ Standard: Less than an indoor temperature of 30°C,
with humidity at 85%. If installing in a high humidity
environment, use one grade thicker insulator by
referring to the table below. If installing in an
unfavourable environment, use thicker one.

࡛ To prevent water from flowing back to indoor units, install
an individual air vent at the top of each indoor unit.
– The air vents should be T or 7 shaped to prevent
dust or foreign substances from entering.
– You may not need to install air vent if the horizontal
drain pipe is in proper slope.
b After pouring some water, reassemble the rubber
cap on the connection part of a flexible hose of
the indoor unit and firmly tighten it with a band to
prevent leakage.
Installation Procedure
CAUTION
࡛ Only in the Cool mode, you can check the correct
operation of the drain pump.
When the electric cable connection has not been

࡛ Reassemble the control box cover and turn on the
indoor unit.
CAUTION
࡛ When the float switch is not detected due to
insufficient water on the drain pan, the drain
pump will not work.
