HORIZONTAL DUCT COVER INSTALLATION
The second step in the downshot airflow conversion is to install Hori- zontal Duct Covers. Horizontal Duct Covers are an accessory, and can be purchased from your authorized dealer. The kit number is CHK001A.
Models 24, 30, 36, 42, and PHB48 require that the supply and return air openings be converted to square. Flanges are shipped with these units to complete this conversion.
Models PHD48/60 and PHB60 supply and return air openings are square and do not require a flange conversion. They do, however, require that cover clips (included with the unit) be installed to ensure a secure fit of the Horizontal Duct Covers.
24, 30, 36, 42 AND PHB48 MODELS:
1.Remove and set aside the four supply air side screws (Figure 8).
2.Remove and set aside the two return air side screws.
