LOCATING UNIT

Fig. 4 shows the air cleaner in the return-air duct of various furnace
installations, with or without air conditioning. Other methods of
installing the unit are permissible if the design criteria outlined in
this section is observed.

A.

A. Planning an Installation

When planning an installation, consider the following:

1. Air cleaner is approved only for indoor installation. If

outdoor installation is used, unit must be housed in weather-
proof enclosure.

2. Air cleaner may be placed in horizontal position on its right

or left side or in vertical position on its bottom or back. It
must be installed on inlet air side of heating and/or cooling
unit. Be sure that airflow through air cleaner is in same
direction as "airflow arrows" on cells.
