been made to assure that the duct system has the capacity to handle the air required for the unit application. If ducting is too small, as in replacement of heating only systems, larger ductwork should be installed. All existing ductwork should be checked for leaks and repairs made accordingly. The duct systems and diffusers should be sized to handle the design airflow quietly. If air noise or excessive airflow is a problem, the blower speed can be changed to a lower speed to reduce airflow. This will reduce the performance of the unit slightly in heating; however, it will increase the temperature rise across the air coil. Airflow must still meet minimum requirements.

Equipment Selection

The following guidelines should be used when mating an Envision Split to an air handler/coil.

•Select R-410A components only.

•Match the air handler to the air handler coil data table.

•Indoor matching adjustable TXV is factory installed on every air handler/coil. Fixed orifice or cap tube systems should not be used.

Utilizing Existing Coil or Air Handler

It is recommended that a new R-410A air handler be installed with an Envision Split considering the long term benefits of reliability, warranty, etc. versus the short term installation cost savings. However, the existing air handler may be retained provided the following:

•Coil currently is R-410A rated

•Coil uses a TXV. No capillary or fixed orifice systems should be used

•A life expectancy of more than 7 years remaining for the air handler and components
