STEP 4: SETTING THE UNIT
Construct a platform for the fan coil unit, as shown in
Figure 2.10. The platform can be constructed of 2 x 4
(minimum), 2 x 6, 2 x 8 and 2 x 10 lumber, as necessary
to achieve sufficient height so that proper condensate
drain line pitch of 1/4" per foot can be maintained. Figure
2.11 shows the approximate normal allowable run of con-
densate piping as a function of the framing lumber used
for platform construction. The platform covering should
be 1/2" plywood minimum.
Attach vibration isolation pads (supplied inside fan coil
unit) to platform covering as shown in Fig. 2.10.
Secure the platform to the joist or floor, depending on
location selected for the fan coil unit. Make sure platform
is level.
For locations where the fan coil unit will be suspended,
suspend platform from overhead by 1/4" threaded rods.
NOTICE: Leave room on sides for servicing.
For installations with a return air box and return air
duct, set fan coil unit on the platform with the elliptical
opening facing in the direction of the return air opening.
The supply air plenum adaptor should overhang the
platform.
DO NOT
let the adaptor support the weight of
the unit.
Do not secure the unit to the platform, as the weight of the
unit will hold it in position.
