The ND Series evaporator units may be suspended from
joists with isolation type hangers or hooks. Suspension
accessories 1HH0403 (ND360), 1HH0404 (ND480) and
1HH0405 (ND600 Air Handler with M1CZ600 Evaporator

hardware. The channels extend across the evaporator
section, the heating section (if included) and the blower
section. Each channel is to be bolted to both sections as
shown in Weight Distribution with Suspension Application
Figures. Refer to the Unit Mounting Dimensions Table for

The same channels can be used in either position. When used to
support a vertical unit, these channels should be cut to match the
bottom dimension of the evaporator section.
The suspension channels have two sets of mounting holes to
accommodate horizontal units with or without a heating coil. On
a horizontal unit without a heating coil, the suspension channels
will extend 3” beyond both ends of the unit.
The same channels can be used to support a horizontal, floor-
mounted unit from below.
After these bottom channels are cut per Note 1, a new hole will have
to be drilled at the cut end if the unit is to be mounted on isolators.
