Room Terminators

Terminators should be located only in the ceiling or floor

for  vertical  discharge.  Horizontal  discharge  is  accept-

able, but is sometimes more difficult to install. Two excel-

lent spots for horizontal discharge are in the soffit area 

above kitchen cabinets (see Figure 1.4) and in the top

portion of closets (see Figure 1.5).

Terminators  should  always  be  out  of  normal  traffic 

patterns  to  prevent  discharge  air  from  blowing  directly 

on  occupants. And  they  should  not  be  located  directly

above shelves or large pieces of furniture. Outside wall 

or  corner  locations  are  recommended  if  the  room  has

more than one outside wall. Locating terminators away

from  interior  doors  prevents  short  cycling  of  air  to  the

return air box.

SHIPMENT OF UNIT

Each fan coil unit is shipped in a single carton. Packed with

the unit, there are vibration isolation pads, a condensate

trap assembly and a factory installed primary float switch.

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 dimen-

sions in Figures 2.2 and 2.3).

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 clear-

ances (see Figures 2.2).
