INSTALLATION MANUAL

AIR CONDITIONER

• Please read this installation manual completely before installing the product.

• Installation work must be performed in accordance with the national wiring

standards by authorized personnel only.

• Please retain this installation manual for future reference after reading

it thoroughly.

TYPE: Ceiling Concealed Duct - Low Static www.lg.com

P/NO : MFL42803121

IMPORTANT!

Please read this instruction sheet completely before installing the product.

This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.

WARNING

• Installation or repairs made by unqualified persons can result in hazards to you and others.

Installation MUST conform with local building codes or, in the absence of local codes, with the National Electrical

Code NFPA 70/ANSI C1-1993 or current edition and Canadian Electrical Code Part1 CSA C.22.1.

• The information contained in the manual is intended for use by a qualified service technician familiar with safety procedures and equipped with the proper tools and test instruments.

• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property damage, personal injury and/or death.

CAUTION:

Improper installation, adjustment, alteration, service or maintenance can void the warranty.

The weight of the condensing unit requires caution and proper handling procedures when lifting or moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.

Safety Precautions

• Always wear safety eye wear and work gloves when installing equipment.

• Never assume electrical power is disconnected. Check with meter and equipment.

• Keep hands out of fan areas when power is connected to equipment.

• R-410A causes frostbite burns.

• R-410A is toxic when burned.

NOTE TO INSTALLING DEALER

: The Owners Instructions and Warranty are to be given to the owner or prominently displayed near the indoor Furnace/Air Handler Unit.

Special warnings

When wiring:

Electrical shock can cause severe personal injury or death. Only a qualified, experienced electrician should attempt to wire this system.

• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.

• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.

• Ground the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.

When transporting:

Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your finger.

When installing...

... in a wall:

Make sure the wall is strong enough to hold the unit's weight.

It may be necessary to construct a strong wood or metal frame to provide added support.

... in a room:

Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to wall and floors.

... in moist or uneven locatinons:

Use a raised concrete pad or concrete blocks provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.

... in an area with high winds:

Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.

... in a snowy area(for Heat Pump Model):

Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

When connecting refrigerant tubing

• Keep all tubing runs as short as possible.

• Use the flare method for connecting tubing.

• Check carefully for leaks before starting the test run.

When servicing

• Turn the power OFF at the main power box(mains) before opening the unit to check or repair electrical parts and wiring.

• Keep your fingers and clothing away from any moving parts.

• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.

Drain Pump use

Drain Piping

• Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow.

• During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit.

• The outside diameter of the drain connection on the indoor unit is

32mm(1-1/4 inch).

Piping material: Polyvinyl chloride pipe inner diometes

Ø 25mm(1 inch) and pipe fittings

• Be sure to install heat insulation on the drain piping.

Heat insulation material: Polyethylene foam with thickness more than 8mm(5/16 inch).

Drain test

The air conditioner uses a drain pump to drain water.

Use the following procedure to test the drain pump operation:

Feed water

Flexible drain hose

Drain Pump

Drain port Glue the joint

Drain hose connection

Use the clip

Drain pan

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end.

• Feed water to the flexible drain hose and check the piping for leakage.

• Be sure to check the drain pump for normal operating and noise when electrical wiring is complete.

• When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

MAX 700mm

(27-9/16 inch)

CAUTION:

After the confirmation of the above conditions, prepare the wiring as follows:

1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control box cover.

2) Provide a circuit breaker switch between power source and the unit.

3) 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.)

4) Specification of power source

5) Confirm that electrical capacity is sufficient.

6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.

7) Confirm that the cable thickness is as specified in the power sources specification.

(Particularly note the relation between cable length and thickness.)

8) Never fail to equip a leakage breaker where it is wet or moist.

9) The following troubles would be caused by voltage drop-down.

• Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the normal function of an overload protection device.

• Proper starting power is not given to the compressor.

HAND OVER

Teach the customer the operation and maintenance procedures, using the operation manual.

(air filter cleaning, temperature control, etc.)

WIERED REMOTE CONTROLLER INSTALLATION

• Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature.

Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by:

- Drafts, or dead spots behind doors and in corners.

- Hot or cold air from ducts.

- Radiant heat from sun or appliances.

- Concealed pipes and chimneys.

- Uncontrolled areas such as an outside wall behind the remote controller.

- This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller

LED's, the remote controller should be installed properly as shown in Fig.1.

(The standard height is 1.2~1.5 m from floor level.)
