Installation guide at the seaside
Sea wind Sea wind
Installation guide at the seaside
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.
2) In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.
Windbreak
Sea wind
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 anticorrosion treatment.
2. Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water
• 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.
• It should be keep more than 70 cm of space
between outdoor unit and the windbreak for easy
air flow.

Fixing Installation Plate(Standard Type)
The wall you select should be strong and solid enough to
prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a concrete wall,
use anchor bolts.
• Mount the installation plate horizontally by aligning the
centerline using a level.
2. Measure the wall and mark the centerline. It is also
important to use caution concerning the location of the
installation plate-routing of the wiring to power outlets is
through the walls typically. Drilling the hole through the
wall for piping connections must be done safely.

Flaring Work and Connection of Piping
Flaring work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.
Cut the pipes
1. Use the piping kit accessory or the pipes purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1.5m (5.0ft) longer than the pipe length.
Burrs removal
1. Completely remove all burrs from the cut cross section of
pipe/tube.
2. Put the end of the copper tube/pipe in a downward direction
as you remove burrs in order to avoid dropping burrs into the
tubing.
Pipe
Reamer
Putting nut on
• Remove flare nuts attached to indoor and outdoor unit, then
put them on pipe/tube having completed burr removal.
(not possible to put them on after flaring work)
Flaring work
• Carry out flaring work using flaring tool as shown below.
• Firmly hold copper pipe in a Bar in the dimension shown in the
table Below.

1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and do flaring work
again.
Connecting the Piping
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the illustration by)
and pull the tubing and drain hose away from chassis.
3. Replace only the plastic tubing holder 1, not the holder 2 in
the original position.
For right rear piping
1. Route the indoor tubing and the drain hose in the direction
of rear right.
2.
Insert the connecting cable into the indoor unit from the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
•
Make a small loop with the cable for easy connection later.
3. Tape the tubing, drain hose, and the connecting cable. Be
sure that the drain hose is located at the lowest side of the
bundle. Locating at the Upper side can cause drain pan to
overflow inside the unit.
If the drain hose is routed inside the room, insulate the hose
with an insulation material* so that dripping from "sweating"(condensation) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.

with vinyl tape so that there may be no gap.
2. Wrap the area which accommodates the rear piping housing section with vinyl tape.
3. Bundle the piping and drain hose together by wrapping
them with vinyl tape for enough to cover where they fit into
the rear piping housing section.

1. Route the indoor tubing and the drain hose to the required
piping hole position.
2. Insert the piping, drain hose, and the connecting cable into
the piping hole.
