SECTION 2: SYSTEM INSTALLATION
NOTICE: Before proceeding with the installation, we
recommend reading through this section of the
manual for an overall understanding of the air
conditioning fan coil unit and air distribution system
component installation procedures.
STEP 1: LOCATING THE UNIT
The fan coil unit may be installed in an unconditioned
space (as long as it is protected from the weather) such
as an attic, garage or crawlspace...or a conditioned
space such as a basement, closet or utility room (see
dimensions in Figure 2.2 and 2.3).
The fan coil unit is shipped in a horizontal air flow
arrangement, but can be easily field-converted to a
vertical air flow arrangement (see Figures 2.8 and 2.9).
When selecting a location, consider the locations as
shown in Figures 2.4, 2.5 and 2.6 of the return air box;
routing of the plenum duct, supply tubing, refrigerant
lines, condensate drain line; and all recommended
clearances (see Figures 2.2 and 2.3).
When installing unit in an attic (above a room ceiling),
recommend installing a secondary drain pan or optional
float switch. Follow local code requirements.
