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 2x4
(minimum), 2x6, 2x8 and 2x10 lumber, as necessary to
achieve proper pitch of 

1

⁄

4

" per foot for the condensate

drain line. Figure 2.11 shows the approximate normal
allowable run of condensate 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 with fan coil unit)
to platform covering as shown in Fig. 2.8.

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 flange should overhang the platform.

DO NOT

let the flange 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.

STEP 5: CONNECTING REFRIGERANT
LINES

Connect refrigerant lines from the outdoor condensing
unit to the fan coil unit in accordance with its manu-
facturer's sizing recommendations for the length 
of the piping run. Proper line sizing is critical to the
operation of the system. Always use proper brazing
procedures. A trickle flow (2PSI) of dry nitrogen to avoid
scale or blockage in the piping system is recommended
while brazing. Spacepak also recommends installing a
sight glass on the liquid line outside of the 
unit as an aid for accurately charging the system.
