CyberOne EC DX IOM Manual
If ductwork is to be installed, always consult your local and
state codes when determining ducting requirements. The
duct system should be designed to allow the air to move with
as little resistance as possible.
The return inlet is provided with flanges for connection of the
ductwork. Refer to the installation drawing provided with the
unit. The connection of ductwork to the unit may be made with
either pop rivets or self-tapping screws.
2.4.2 Upflow Configuration Air Patterns
In an upflow configured unit, the conditioned supply air
has two methods of discharge: Ducted or through a 2- or
3-way grilled plenum box (see Figure 8). There are two
basic air patterns: Front free return and rear ducted return.
If ductwork is to be installed, always consult your local or
state codes when determining ducting requirements. The
duct system should be designed to allow the air to move
with as little resistance as possible.
