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 nationed wiring regulation.
