a horizontal or vertical position.
The location of the fan coil is not as critical as
it is with conventional low velocity systems.
Location of the fan coil unit will depend on:

Minimizing all duct runs.

Maximizing usable floor space.

Reducing structural changes.

Serviceability and access to the unit.

Location of heat/cool source to fan coil.

Available space in mechanical room.
When suspending the unit from the ceiling, it
is recommended to use spring vibration
isolators at each corner of the fan coil unit.
This will provide a secure means of hanging
the unit, and will also reduce any transfer of
vibration into the building structure. Rubber
belting is also acceptable. Another common
means of suspending the fan coil is with
angle iron, sheet metal channel, or uni-strut
placed underneath the unit, and supported by
threaded rod. If this method is used, isolators
(rubber or equivalent) must be placed
between the fan coil unit, and the support.
Ensure that the hanging method does not
hinder any piping, electrical runs, filter access,
or blower access.
trunk duct
Inspect the location for the trunk duct as per
the duct layout for the home or building. An
important consideration in placement of the
main supply plenum is that the fan coil unit
must be connected to the main supply
plenum. Therefore, it is necessary to have a
clear path from the fan coil unit to the main
supply plenum.
supply duct connections
There are numerous fittings required at this
stage of the installation. These fittings may
include couplings, block ends, reducers,
elbows (90

and 45

), and tee's.
Place the fittings inside the pipe you intend to
connect. After pushing the supply duct over
the fitting as tight as possible, use four
screws on each side of the connector to
fasten. Locate the screws at 90

to one
another. After securing the connector with the
screws, be sure to
tape or seal all joints to
eliminate any air leaks.
elbow and tee placement
It is recommended to avoid penetrations
within the first 18” of the plenum Where
possible allow 18" before installing any tee or
saddle. An elbow or an offset elbow can be
incorporated in the 18” dimension
For best performance of the system, keep the
number of elbows and tees to a minimum.
When using elbows always use adjustable
type elbows for
MaxAir(e) ™ systems. When
utilizing tees that deflect both air steams at
90

angles try to maintain a 50/50 split on the
air stream. When using tees that deflect one
air stream at 90

try to maintain a 70%
straight through to 30% at right angle ratio.
These are approximate ratios plus/minus
10%.
connecting the ducts to the fan coils
Once the main plenum duct and the fan coil
is in place, they can be fitted together. You
may need to rotate the plenum in order to
ensure your branch take-off lines up properly.
Connecting the main supply plenum with the
use of flexible duct as a connector or a
canvas connector is permitted. The flexible
duct should be used as a connector only. The
use of flexible duct as a supply plenum is not
permitted.
When ductwork is being mounted in the
basement between the joists, the use of
appropriate sheet metal strapping (field
supplied) can be used to secure the duct to
the joists. When installing ductwork in the
attic, it should be laid upon ceiling joists and
wrapped with insulation as per local building
codes. Running the duct high in the attic
increases the duct losses or gains.
