1. 2. Special precautions
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected
and checked.
• Highly dangerous electrical voltages are used in this system. Carefully refer to the wir-
ing diagram and these instructions when wiring. Improper connections and inadequate
grounding (earthing) can cause accidental injury or death.
• Ground (Earth) 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
Properly insulate any tubing run inside a room to prevent "sweating" that can cause
dripping and water damage to walls and fl oors.
...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.
