The total unit model number consists of a base model number followed by individual model numbers. The base
model number identifies main unit features. Individual module numbers identify module configurations and optional
features.

When determining unit orientation
(or Supply Air Flow as it is
identified in the base model
number below), consider the air to
be “hitting you in the back of the
head” when you are facing the
return air end of the unit.
If you have a “Left Hand”
unit, then all connections
will be on the left hand
side of the unit. Air will
flow from right to left as
you look at the left side.
If you have a “Right Hand”
unit, then all connections
will be on the right hand
side of the unit. Air will
flow from left to right as
you look at the right side.
