Unit Mounting
ND360, 480 & 600
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 Section) may be ordered separately. All Suspension accessories include three suspension channels and
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 mounting details and Corner Weights Tables for unit weight distribution.

1The 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.
2The 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.
3The same channels can be used to support a horizontal, floor- mounted unit from below.
4After 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.
