OWNER'S MANUAL

SPLIT AIRCONDITIONING SYSTEM

This air conditioner meets strict safety and operating standards. The installer of this unit must install or service this unit so it operates safely and efficiently.

The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

Contact Installer if Necessary:

The installation instructions are for a experienced installer. If you are not an experienced installer, contact a local installer for help. If you require help with service, contact your certified dealer or Daewoo Electronics for additional instructions.

If Unit is Installed Improperly:

The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this manual.

Precautions When Wiring:

• Do not plug in the unit until all connections (tubing, drain hose, mounting, etc.) have been made and double-checked.

• High voltages are present in this unit and are very dangerous. Please refer to these instructions and diagrams when wiring. Improper connections or inadequate grounding can cause accidental injury.

• This unit must be grounded in accordance with local electrical codes.

• Connect wires and pipes securely and tightly as loose connections/wiring may cause overheating at connections and a possible fire hazard.

Precautions When Transporting:

• When transporting the unit, be very careful and get help as the units are very heavy. Be careful of sharp edges on the units also.

Precautions When Installing:

• When installing in a ceiling or wall, make sure the ceiling/wall is strong enough to hold the unit’s weight. A frame may be necessary for added support.

• When installing in a room, make sure the tubes are well insulated to protect the walls and furniture from sweating of the tubes.

• When installing in moist or uneven locations, make sure to use a raised level concrete pad or concrete blocks to provide a level, solid foundation for the outdoor unit; this prevents water damage and vibration.

• When installing in an area of high winds, make sure to securely anchor the outdoor unit down with bolts and a metal frame.

When Connecting Refrigerant Tubing:

• Keep all tubing as short as possible.

• Use the flare method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten , making sure not to overtighten.

• Check the tubes carefully for leaks before starting the test run.

When Servicing:

• Make sure the power is off and the unit is unplugged before opening the unit to troubleshoot or repair electrical parts and wiring.

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

• Clean up the sight after you finish, making sure no metal scraps and wiring are left in the unit.

• The Air conditioner shall be installed in accordance with the nat ioned wiring regulation.

NOTES:

• After installation it must be possible for the user to disconnect the power supply plug.

• If the AC outlet is a 3-pronged type or other, have an electrician install a new outlet.

• Contanct service man when replace the power cord set.

• The specification of AC connection is 1.5mm

X5PX6m.

Maximum Height 7M(21Ft) Maximum Length 15M(49Ft)

1. Determine the type of wall (sheetrock, concrete, etc.) and make sure it is strong enough to hold indoor unit. Select an approximate position for the unit, taking the required distances away from walls/AC outlet into consideration.

INSTALLATION

INDOOR UNIT

• Do not install the unit in an area with direct sunlight, near heat sources (radiator, etc.), or an area where leakage of flammable gas may be expected.

• Select a position in the room, high on the wall, where the whole room can be uniformly cooled.

• Select a location that can hold the weight of the unit and where the copper tubing, drain hose and Indoor to Outdoor Wire have the shortest distance to the Outdoor unit.

• Make sure the Indoor unit is installed at least 10cm (3.95in) away from the top and left side wall and at least 30cm (11.8in) from AC outlet and right side wall (see Overview figure on previous page).

OUTDOOR UNIT

• Do not install the unit in an area near heat sources, exhaust fans, or an area where leakage of flammable gas may be expected.

• Do not install the unit in a humid, damp or uneven location.

• Select a location that is well ventilated .

• Leave enough room around the unit for air intake, exhaust and possible maintenance.

2. Determine if the hole is to be made at the left or right hole location.

3. Using drill with hole-cutting attachment or equivalent, cut a hole 65mm (2.56") in diameter. The hole should be made at a slight downward slant to the outdoor side. Measure the thickness from the inside to outside edges and cut a PVC pipe at a slight angle 1/4" shorter than the thickness of the wall and insert pipe in wall.

4. For sheetrock, wooden or similar wall, measure down from the ceiling using a level or tape measure and attach the wall bracket to the wall using 4 screws. If you are not able to line up the holes with the beams, use toggle bolts. Make sure the wall bracket is even and flush against the wall.

CAUTION

• Before making hole, make sure there are no studs, pipes, electrical wiring or conduit directly behind the area to be cut.

For Concrete, or similar type wall, make holes into the wall and insert concrete nails instead of screws.

INSTALLING THE WALL BRACKET:

To install the wall bracket, follow the procedures below. One hole is required for the tubing and may be either on the left or right side.

INSTALLATION (CONTINUED)

NOTES:

• This appliance must be installed according to National power supply requirement.

• If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.

• Make sure the Indoor unit’s AC cord is not connected to AC power when connecting the indoor/outdoor wire.

• When connecting wires, make sure they are fully inserted and minimum copper wire is exposed. If they are not, shorting, overheating, no operation, etc. may occur.

• Be sure to comply with local codes on running a wire from the indoor to the outdoor unit.

1. Open the connection cover on the indoor unit to access the connection area.

Remove the Connection Cover.

• Loosen one screw for fixing the Connection Cover.

• Loosen one screw at the Connection Cover.

• Remove the Connection Cover.

2. Fish the indoor/outdoor wire from the rear of the indoor unit through the front of the unit. For easier connection, make sure enough wire is pulled through the front. Use the wire as shown below:

INSTALLING THE INDOOR/OUTDOOR WIRE TO THE INDOOR UNIT FOR AC CONNECTION

The Indoor/Outdoor wire is used to supply AC from the Indoor unit to the Outdoor unit. To install the indoor/outdoor wire, follow the procedures below.

3. To connect wires, loosen the screw in the Terminal Block and insert the correct wires like following figure. Connect the Brown wire to the “L” connection, Yellow/Green wire to the “ ” connection, the Blue wire to “Y” connection, the Blue wire to “1” connection and the Black wire to “2” connection.

4. Connect the wires to the housing and terminals on the control board individually according to the outdoor unit connection.

The used connection cable connected to indoor and out-

door unit must be ;

1) H07RN-F 3G1.5mm

(NOT INCLUDED)

2) H07RN-F 2G1.5mm

(NOT INCLUDED)

3) UL2464 AWG22 2G0.75mm

2. Make sure the drain hose and copper tubing are wrapped with the rubber insulation. Using the tape, wrap the indoor/outdoor wire, copper tubing and drain hose together.

MOUNTING THE INDOOR UNIT

The Indoor unit must be mounted before connecting the indoor/outdoor wire, drain hose and copper tubing. To mount, follow the procedures below:

1. The tubing can be extended in 4 directions as shown below. No cutting is necessary for left/rear and right/rear tubing connections. If using left or right tubing connections, remove the plastic area with a hacksaw so pipes can go through.

CAUTION:

• Make sure the Indoor unit’s AC cord is not connected to AC power when performing these procedures.

• Be sure to comply with local codes on running a wire from the indoor to the outdoor unit.

• DO NOT LET THE INDOOR/OUTDOOR WIRE COME IN DIRECT CONTACT WITH THE TUBING OR HOSE!
