READ BEFORE INSTALLING UNIT

To avoid risk of personal injury, property damage, or product damage due to the weight of this device and sharp edges that may be exposed:

Air conditioners covered in this manual pose an excessive weight hazard. Two or more people are needed to move and install the unit. To prevent injury or strain, use proper lifting and carrying techniques when moving unit. Carefully inspect location where air conditioner will be installed. Be sure it will support the weight of the unit over an extended period of time.

Handle air conditioner with care. Wear protective gloves whenever lifting or carrying the unit. AVOID the sharp metal fins of front and rear coils.

Make sure air conditioner does not fall during installation.

If a new electrical outlet is required, have the outlet installed by a qualified electrician before installing unit.

NOTE: DO NOT USE ANY SCREWS OTHER THAN THOSE SPECIFIED HERE.
