When arranged horizontally, the ND600 airhandler and
M1CZ600 evaporator coil can be suspended from joists with
hanger rods using a suspension accessory. 

The suspension channels require no drilling or cutting. Each
channel has enough holes in its bottom flange for:

1.

Four bolted connections to the evaporator coil section. 
(Only two are used on the outside supports)

2.

One bolted connection to the heating coil section.

3.

Four bolted connections to the blower section. (Only two 
are used on the outside supports)

See Figure  details for securing suspension channels.

When the heating section is not included, each channel will
extend 3" beyond the front and the rear of the unit. Bolt holes
in the bottom flange of each channel will still align with the
holes provided in the top framework of the evaporator section
and the blower section.

For both outside channels and for the Point 1 locations on the
center channel, the bolted connections are to be made where
the top sheet metal panels are attached to the unit
framework. The ¼” screws and cage nuts must be removed
and may be discarded. For the Point 2 locations on the center
channel, the bolted connections are to be made through the
knockouts in the top sheet metal panels. 5/16” cage nuts are
provided in the unit framework under these knockout
locations. Note that these cage nuts are part of the basic unit.
They are not supplied with the suspension accessory.
