ENVISION SERIES INSTALLATION MANUAL

General Installation Information (continued)

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.

•Select 12 SEER or higher air handler/coil.

•Match the air handler to the air handler coil data table on page 9.

•Indoor matching adjustable TXV should be used with any 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 ben- efits 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
