Installation

Indoor unit

1. Do not have any heat or steam near the unit.

2. Select a place where there are no obstacles

in front of the unit.

3. Make sure that condensation drainage can be

conveniently routed away.

4. Do not install near a doorway.

5. Ensure that the interval between a wall and

the left (or right) of the unit is more than

50cm. The unit should be installed as high as

possible on the wall, allowing a minimum of

10cm from ceiling.

6. Use a stud finder to locate studs to prevent

unnecessary damage to the wall.

Outdoor unit

1. If an awning is built over the unit to prevent

direct sunlight or rain exposure, make sure

that heat radiation from the condenser is not

restricted.

2. Ensure that the space around the back and

sides is more than 10cm. The front of the unit

should have more than 70cm of space.

3. Do not place animals and plants in the path

of the warm air.

4. Take the weight of the air conditioner into

account and select a place where noise and

vibration are minimum.

5. Select a place where the warm air and noise

from the air conditioner do not disturb

neighbors.

Rooftop Installations:

If the outdoor unit is installed on a roof

structure, be sure to level the unit. Ensure the

roof structure and anchoring method are

adequate for the unit location. Consult local

codes regarding rooftop mounting.

Installation guide at the seaside

10 MPS Multi Air Conditioner

Installation

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.

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.

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

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.

3) Select a well-drained place.

• 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.

Installation

The wall you select should be strong and solid

enough to pr

event vibration

1. Mount the installation plate on the wall with

type "A" scr

ews. If mounting the unit on a

concrete

wall, use anchor bolts.

Mount the installation plate ho

rizontally by

aligning the cente

rline using a level.

2. Measure the wall and mark the centerline. It

is also impo

rtant to use caution concerning

the location of the installation plate-routing

of the wi

ring to power outlets is through the

walls typically. Drilling the hole through the

wall for piping connections must be done

fely.

direction of drain hose.

• Drill the hole for anchor bolt on the wall.

CAUTION:

•

This air-conditioner uses a drain pump.

• Horizontly install the unit using a level

2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in

suspension in factories, etc.

3. Avoid places where inflammable gas is generated, flows in, is stored or vented.

4. Avoid places where sulfurous acid gas or corrosive gas is generated.

5. Avoid places near high frequency generators.

• Thoroughly study the following installation locations:

1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere

to the turbo fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange

reduction, spraying, dispersing of water drops, drain pump malfunction, etc.

In these cases, take the following actions:

• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient

capacity so that it draws oily steam which should not flow into the suction of the air

conditioner.

• Make enough distance from a cooking room to install the air conditioner in such a place

where it may not suck in oily steam.

• Drill the piping hole on the wall slightly tilted to the

outdoor side using a Ø 70 hole-core drill.

• Although the room temperature sensor is in the indoor unit, the remote controller should

be installed in such places away from direct sunlight and high humidity.

Installation of the remote controller

• Select places that are not splashed with water.

• Select control position after receiving customer approval.

• The room temperature sensor is built in the indoor unit.

• This remote controller equipped with liquid crystal display. If this position is higher or lower,

display is difficult to see.(The standard height is 1.2 ~ 1.5m high)

Routing of the remote controller cord

• Keep the remote controller cord away from the refrigerant piping and the drain piping.

• To protect the remote controller cord from electrical noise, place the cord at least 5cm away

from other power cables (audio equipment, television set, etc.)

• If the remote controller cord is secured to the wall, provide a trap at the top of the cord to

prevent water droplets from running.

Installation

Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the

following procedure.

Cut the pipes and the cable.

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 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.

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

1. Firmly hold copper pipe in a die in the dimension

shown in the table below.

4. Indoor unit installation

Hook the indoor unit onto the upper portion of

the installation plate.(Engage the two hooks

of the rear top of the indoor unit with the

upper edge of the installation plate.) Ensure

that the hooks are properly seated on the

installation plate by moving it left and right.

Press the lower left and right sides of the unit

against the installation plate until the hooks

engage into their slots(clicking sound).

Connecting the piping to the indoor unit and

drain hose to drain pipe.

1. Align the center of the pipes and sufficiently

tighten the flare nut by hand.

2. Tighten the flare nut with a wrench.

3. When extending the drain hose at the indoor

unit, install the drain pipe.

Wrap the insulation material around the

connecting portion.

1. Overlap the connection pipe insulation

material and the indoor unit pipe insulation

material. Bind them together 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.
