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 dan-
gerous. 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 connec-
tions 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 out-
door 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 electri-
cal parts and wiring.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the sight after you finish, making sure no met-
al scraps and wiring are left in the unit.
• The air conditioner shall be installed in accordance with
the nationed wiring regulation.
