All panels must be secured in place when the unit
is lifted.
The condenser coils should be protected from
damage by the rigging cables with plywood or
other suitable material.

fired units to prevent moisture from entering the
unit which could cause damage to electrical com-
ponents. Allow this closure label to remain in place
until the combustion air hood is to be installed
