There are no buried--line applications greater than 36 in. (914.4
mm).
If refrigerant tubes or indoor coil are exposed to atmosphere, they
must be evacuated to 500 microns to eliminate contamination and
moisture in the system.
Outdoor Unit Connected to Factory Approved Indoor
Unit
Outdoor unit contains correct system refrigerant charge for
operation with factory approved AHRI rated indoor unit when
connected by 15 ft. (4.57 m) of field--supplied or factory--accessory
tubing, and factory supplied filter drier. Check refrigerant charge
for maximum efficiency.

the environmentally sound refrigerant
This product has been designed and manufactured to meet
Energy Star criteria for energy efficiency when matched
with appropriate coil components. However, proper
refrigerant charge and proper air flow are critical to achieve
rated capacity and efficiency. Installation of this product
should follow all manufacturing refrigerant charging and air
flow instructions. Failure to confirm proper charge and
air flow may reduce energy eff iciency and shorten
equipment life.
