•Observe all local, state and national electric codes. Contact your local government for more information on electrical codes.

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.

WARNING:

•ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN/INSTALLER SHOULD ATTEMPT TO WIRE THIS SYSTEM.

•THE APPLIANCE IS NOT INTENDED FOR USE BY CHILDREN OR INFIRM PERSONS WITHOUT SUPERVISION

•YOUNG CHILDREN SHOULD BE SUPERVISED TO ENSURE THAT DO NOT PLAY WITH THE APPLIANCE

Precautions When Wiring:

•Do not plug in the unit until all connections (tubing, drain hose, mounting, etc.) have been made and dou- ble-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 nationed wiring regulation.

To prevent flicker impressions during the start of the compressor (technical process) following installation conditions do apply.

1.The power connection for the air conditioner has to be done at the main power distribution. This distribution has to be of an low impedance. Normally the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max!

2.No other equipment has to be connected to this power line.

3.For detailed installation acceptance please refer to your contract with the power supplier.

If restrictions do apply for products like washing machines, air conditioners or electrical ovens.

4.For power details of the air conditioner refer to the rating plate of the product.

CONSIGINES D’INSTALLATION RACCORDEMENT ELECTRIQUE

INSTRUZIONI PER L’INSTALLAZIONE DEL CONDIZIONATORE

D’ARIA PER STANZE

NOTA DELLA DIRETTIVA EMC 89/336 EEC

Allo scopo di prevenire l’ effetto di FLICKER (variazione della luce) alla partenza del compressore, durante l’installazione seguire l punti sottoelencatl.

1.Il collegamento dell’ alimentazione, del condizionatore, deve essere fatto con una linea preferenziale dlrettamente al quadro principale o contatore, e deve essere a bassa impedenza.

Normalmente questa lmpedenza la si ottiene al punto di fusione di 32 A ; perll condizionatore usare un fusibile da 16 A max.

2.Nessun altro apparecchio elettrico dovra essere collegato alla stessa linea di alimentazione.

3.Per maggiori dettagll circa l’ accettazione dell’ installazione del condizionatore, fare riferimento al contratto con l’ Ente erogatore dell’ Energla Elettrica e verificare che non ci siano restrizioni in atto all’ Installazione di prodottl elettrici ad alto consumo.
