INSTALLATION GUIDE
Up to four fan coil units can be connected to one outdoor unit.
Refer to the Product Data for approved combinations.
Ideal installation locations include:
Each Indoor
Unit
S A location where there are no obstacles near inlet and outlet area.
S A location which can bear the weight of indoor unit.
S Do not install indoor units near a direct source of heat such as
direct sunlight or a heating appliance.
S A location which provides appropriate clearances as outlined in
Fig. 7.
Outdoor
Unit
S A location which is convenient to installation and not exposed to
strong wind. If unit is exposed to strong winds it is
recommended that a field--fabricated wind baffle be used. (See
Fig. 15)
S A location which can bear the weight of outdoor unit and where
the outdoor unit can be mounted in a level position.
S A location which provides appropriate clearances as outlined in
Fig. 8 and Fig. 9.
S Do not install the indoor or outdoor units in a location with
special environmental conditions. For those applications, contact
your Carrier Representative.
INDOOR UNIT INSTALLATION
INSTALL MOUNTING PLATE
For each fan coil:
1. Carefully remove the mounting plate, which is attached to
the back of the indoor unit.
2. The mounting plate should be located horizontally and level
on the wall.
3. If the wall is block, brick, concrete or similar material, drill
.2” (5 mm) diameter holes and insert anchors for the ap-
propriate mounting screws.
4. Attach the mounting plate to the wall.

Refrigerant Line Routing
The refrigerant lines may be routed in any of the four directions
showninFig.12(a)and(b).
For maximum serviceability, it is recommended to have refrigerant
line flare connections and the drain connection on the outside of
the wall that the fan coil is mounted on.

If piping is going through the back:
1. Determine pipe hole position using the mounting plate as a
template. Drill pipe hole diameter per chart below. The
outside pipe hole is 1/2--in. (13 mm) min. lower than inside
pipe hole, so it slants slightly downward (see Fig. 13).
If piping is going to exit from the left rear, it is recommen-
ded to field--fabricate piping extensions to get the flare con-
nections to the outside of the wall.

If piping is going through the right or left side:
1. Use a small saw blade to carefully remove the correspond-
ing plastic covering on side panel and drill the appropriate
size hole where the pipe is going through the wall. See Fig.
12 (c).
2. Remove knockout 1 if you are running only the wiring.
Remove knockout 1 and 2 or knockout 1, 2 and 3 if you are
running both piping and wiring through the side of the unit.
