• After 40 min heating mode operation, at 4 min interval, whether to carry out defrost control or not and the time of
defrost control are determined according to the following conditions.
1) While in heating mode operation, the maximum of the indoor pipe temperature is measured and it is compared
with the present indoor pipe temperature to get the difference of the indoor pipe temperatures (=the maximum
temperature of indoor pipe - the present temperature of indoor pipe), according to wich, whether to carry out defrost control or not is determined.
2) According to the need of defrost control shown above and the elapsed time of heating mode operation at that
moment, the defrost control time is determined.
3) When the determined time of defrost control is below 7 min, heating mode operation continues without carrying
out defrost control.According to the procedure stated above, the determination is made again.When the defrost
control time is 7 min or longer, defrost control is then carried out.
• While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the present
temp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of the indoor pipe - the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost control is
completed and heating mode operation is carried out.
• While in defrost control, if the defrost time determined before the start of defrost control is completed, defrost control stops and heating mode operation is carried out regardless of the above condition.

5) Installation guide at the seaside
CAUTION
1. Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion
on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.
3. If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it
needs additional anticorrosion treatment on the heat exchanger.
Selecting the location(Outdoor Unit)
1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the outdoor unit on the opposite side of the sea wind direction.
Sea wind
Sea wind
2) In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.
Windbreak
• It should be strong enough like concrete to prevent
the sea wind from the sea.
• The height and width should be more than 150% of
the outdoor unit.
Sea wind
•It should be keep more than 70 cm of space
between outdoor unit and the windbreak for easy
air flow.
3) Select a well-drained place.
1. If you can't meet above guide line in the seaside installation, please contact LG Electronics for the additional anticorrosiontreatment.

are set to the open position.
ñ Remove the valve stem caps and confirm that
the valve stems are in the raised position.
ñ Be sure to use a hexagonal wrench to operate
the valve stems.
(2) Operate the unit for 10 to 15 minutes.
(3) Stop operation and wait for 3 minutes, then
connect the charge set to the service port of
the 3-way valve.
ñ Connect the charge hose with the push pin to
the service port.
(4) Air purging of the charge hose.
ñ Open the low-pressure valve on the charge set
slightly to air purge from the charge hose.
(5) Set the 2-way valve to the closed position.
-32-
(6) Operate the air conditioner at the cooling
cycle and stop it when the gauge indicates
1kg/cm2g.
(7) Immediately set the 3-way valve to the closed
position.
ñ Do this quickly so that the gauge ends up indicating 3 to 5kg/cm2g.
(8) Disconnect the charge set, and mount the 2way and 3-way valveís stem nuts and the service port nut.
ñ Use torque wrench to tighten the service port
nut to a torque of 1.8 kg.m.
ñ Be sure to check for gas leakage.
Do not use the existing charge set for R-22.
It is necessary to use new charge set for R-410A.
The pressure of R-410A is 1.6 times higher than
that of R-22. Thus, the high pressure side gauge of
charge set should be used higher pressure gauge
of 50kg/cm2 range.

and press the check valve on the charge set to
purge the air. (Be careful of the liquid refrigerant). The procedure is the same if using a gas
cylinder.
(3) Open the valve (Lo side on the charge set and
charge the system with liquid refrigerant.
– If the system can not be charged with the specified amount of refrigerant, it can be charged
with a little at a time (approximately 150g each
time) while operating the air conditioner in the
cooling cycle; however, one time is not sufficient, wait approximately 1 minute and then
repeat the procedure (pumping down-pin).
-35-
This is different from previous procedures.
Because you are charging with liquid refrigerant
from the gas side, absolutely do not attempt to
charge with larger amounts of liquid refrigerant
while operating the air conditioner.
(4) Immediately disconnect the charge hose from
the 3-way valveís service port.
ñ Stopping partway will allow the gas to be discharged.
ñ If the system has been charged with liquid
refrigerant while operating the air conditioner
turn off the air conditioner before disconnecting
the hose.
(5) Mount the valve stem nuts and the service
port nut.
ñ Use torque wrench to tighten the service port
nut to a torque of 1.8 kg.m.
ñ Be sure to check for gas leakage.
