SECTION 2: SYSTEM INSTALLATION
NOTICE: Before proceeding with the installa-
tion, we recommend reading through this sec-
tion of the manual for an overall understanding
of the air conditioning fan coil unit and air dis-
tribution system component installation proce-
dures.
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) or a
conditioned space such as a basement, closet or utility
room. Please refer to Figure 2.2 for unit sizes and
recommended service clearances.
When selecting a location, consider the location of the
unit in relation to the return air box or filter box as shown
in Figures 2.3, 2.4. The return air duct should have at
least one 90° bend to avoid unnecessary sound feed-
back to the living space from the fan coil unit.
When selecting a location, consider the layout of the
plenum duct, supply tubing, refrigerant lines and con-
densate drain line.
When installing the unit above a finished ceiling or living
space, install a secondary drain pan. Always follow local
code requirements.
