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 suffi- cient 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 im- portant operating and maintenance (servicing) in- structions in the literature accompanying the appli- ance.
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.
Precautions When Wiring:
•Do not plug in the unit until all connections (tubing, drain hose, mounting, etc.) have been made and
•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 acciden- tal injury.
•This unit must be grounded in accordance with local electrical codes.
•Connect wires and pipes securely and tightly as loose connec- tions/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 insulat- ed 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.
