TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful for your health and may consume
more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may
block the air flow or weaken the cooling / dehumidifying functions.

12 INSTALLATION OF UNIT
Welding, as when heating without nitrogen substitution a large amount of the oxide film is
formed on the internal piping.
The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of
oil pump in compressor.
It prevents normal operation of the compressor.
In order to avoid this problem, Welding should be done after replacing air by nitrogen gas.
When welding plumbing pipe, the work is required.

! CAUTION
1 Always use the nitrogen.(not use oxygen, carbon dioxide, and a Chevron gas):
Please use the following nitrogen pressure 0.02MPa
Oxygen --------- Promotes oxidative degradation of refrigerant oil.
Because it is flammable, it is strictly prohibited to use
Carbon dioxide --- Degrade the drying characteristics of gas
Chevron Gas ---- Toxic gas occurs when exposed to direct flame.
2 Always use a pressure reducing valve.
3 Please do not use commercially available antioxidant.
The residual material seems to be the oxide scale is observed.
In fact, due to the organic acids generated by oxidation of the alcohol contained in the anti-oxidants, ants nest corrosion occurs. (causes of organic
acid ’ alcohol + copper + water + temperature)
INSTALLATION OF UNIT 13
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following
procedure.
Cut the pipes and the cable.
- Use the accessory piping kit or the pipes purchased locally.
- Measure the distance between the indoor
and the outdoor unit.
- Cut the pipes a little longer than measured
distance.
- Cut the cable 1.5 m longer than the pipe
length.

- Hold the tubing with your two hands
closely and then bend or stretch it slowly
not to make any crack.
- Remember that the radius (R) should not
exceed 70 mm (Refer to Fig. 1)

- The screws which fasten the wiring in the
casing of electrical fittings are liable to
come loose from vibrations to which the
unit is subjected during the course of
transportation. Check them and make
sure that they are all tightly fastened.
(If they are loose, it could give rise to
burn-out of the wires.)
- See to it that the starting voltage is maintained at more than 90 percent of the
rated voltage marked on the name plate.
- The following troubles would be caused
by voltage drop-down.
Vibration of a magnetic switch, damage
on the contact point there of, fuse breaking, disturbance to the normal function of
a overload protection device.
Vacuum Drying of the Connecting Pipes and the Indoor
Unit
The air which contains moisture remaining in
the refrigeration cycle may cause a malfunction on the compressor.
1 Confirm that both the liquid side valve and
the gas side valve are set to the closed position.
2 After connecting the piping, check the
joints for gas leakage with gas leak detector.
3 Remove the service port nut, and connect
the gauge manifold and the vacuum pump
to the service port by the charge hose.
4 Vacuum the indoor unit and the connecting
pipes until the pressure in them lowers to
below - 76 cmHg.
5 Remove the valve stem nuts, and fully
open the stems of the 2-way and 3-way
valves with a hexagon wrench.

Checking the Drainage
1 Remove the inlet grille with your hands as
shown (right and left) and pull in the direction indicated by the arrow.
2 Check the drainage
- Pour a glass of water into the drain pan.
- Ensure if water flows drain hose of indoor
unit.
FINAL CHECK AND TEST RUN 19
After installing the unit, perform the final check and running test as follows:
Final check points
① Is the unit securely mounted?
② Is the installation location adequate?
③ Is the water piping work adequately and without leakage?
④ Are trapped drain lines installed at condensate drain connections?
⑤ Has the refrigeration cooling cycle been kept sealed?
⑥ Is the electrical wiring adequate and are the screws tightened on terminals?
After the above final checkings, prepare the running test as follows:
① Connect compound gauges to the check joints at discharge and suction sides of the compressor.
② Turn all switches "OFF".
③ Turn the main switch "ON".
Running test should be accomplished as follows:
① Set operation switch at "FAN" and the fan will start. Check to ensure that the fan sounds normal.
② Next, set it at "COOL" and the compressor will start. Check to ensure that the compressor
sounds normal.
③ Check discharge and suction pressure on the compound gauges.
④ Check working voltage, phase balance and running current.
⑤ Check to ensure that the thermistor functions properly.
⑥ Check to ensure that the high pressure control switch functions correctly.

INSTALLATION GUIDE AT THE SEASIDE
! CAUTION
• Air conditioners should not be installed
in areas where corrosive gases, such as
acid or alkaline gas, are produced.
• 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.
• 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.
1 Selecting the location(Outdoor Unit)
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 to prevent
oudoor unit from the sea wind.
Windbreak
Sea wind
- It should be strong enough like concrete
to prevent the outdoor unit from the sea
wind.
- The height and width should be more
than 150% of the outdoor unit.
- It should be keep more than 70 cm of
space between outdoor unit and the
windbreak for easy air flow.
3 Place with fluent water draining
- Install at a place with fluent water draining to prevent damage from localized
heavy rain and avoid frequent flooded
area.
- If you can’t meet above guide line in the
seaside installation, please contact LG
Electronics for the additional anticorrosion.
- Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on
the heat exchanger by using water
