When the heater is lifted for suspension, support the bottom of the heater with plywood
or other appropriately placed material. If the bottom is not supported, damage could
occur. Before hanging, verify that any screws used for holding shipping brackets were
re-installed in the cabinet.
NOTE: If installation of a Model UDBP or UDBS Size 30-125 includes an optional step-
down transformer (Option CG2 or CG4), attaching the transformer bracket is part of the
suspension procedure. Follow the instructions shipped with the transformer.
When the heater is lifted for suspension, support the bottom of the heater with plywood
or other appropriately placed material. If the bottom is not supported, damage could
occur. Before hanging, verify that all screws used for holding shipping brackets were
re-installed in the cabinet.

Paragraph 4.2 and the illustration in FIGURE 5 or 6.
