When Wiring
ELECTRICAL SHOCK CAN CAUSE SE-
VERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
• Do not supply power to the unit all wiring and tubing are
completed or reconnected and checked.
• Highly dangerous electrical voltage are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or
death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fi re
hazard.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your
knees when lifting to reduce strain on your back. Sharp
edges or thin aluminum fi ns on the air conditioner can
cut your fi ngers.
When Installing...
...In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit's weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
...In a Room
Property insulate any tubing run inside a room to
prevent "sweating" that can cause dripping and water
damage to walls and fl oors.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to pro-
vide a solid, level foundation for the outdoor unit. This
prevents water damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and
a metal frame. Provide a suitable air baffl e.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
• Use the frame method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of
the fl are and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free con-
nection.
• Check carefully for leaks before starting the test run.
