5. Hanging the
Heater (cont'd)
5.2 Lifting and
Suspending
(cont'd)
When the heater is lifted for suspension, the bottom must be protected. If the wooden
crate bottom has been removed, the bottom of the heater will have to be supported
with plywood or other appropriately placed material. If the bottom is not supported, the
bottom access panel could be damaged. Also, when lifting a blower unit, support the
blower and motor to prevent the unit from tipping.
All blower models have legs that support the blower assembly during shipping. After
the unit is suspended, these legs should be removed.
Be sure that the threaded hanger rods are locked to the heater as shown in
FIGURE
8.
If an optional downturn air nozzle is used, the unit must be suspended from four
points to ensure level suspension. Two hanger brackets are included in the downturn
option package and must be field-installed on fan-type units with standard two-point
suspension. For additional information, refer to Paragraph 28 and the instructions that
are furnished with the option package.
When blower-type units are equipped with an optional blower/filter cabinet, there
are two suspension points on the blower cabinet hanger bar. Suspend a unit equipped
with a blower/filter cabinet from four points, using the two heater hanger bracket assem-
blies closest to the front of the heater and the two suspension points on the blower/filter
cabinet.
If one of the four optional, field-installed hanger kits has been ordered for your heater, it
will have been shipped separately. Each option package includes a list of components
and complete, step-by-step assembly instructions.
