Rigging Details - Daikin DFG Series Installation Instructions Manual

RIGGING DETAILS

To prevent property damage, the unit should remain in an
upright position during all rigging and moving operations.
To facilitate lifting and moving when a crane is used, place
the unit in an adequate cable sling.
Do not lift units two at a time. Provisions for forks have
been included in the unit base frame. Minimum fork length is
72" to prevent damage to the unit.
Provisions for forks have been included in the unit base frame. No
other fork locations are approved.
To prevent possible equipment damage, property damage,
personal injury or death, the following bullet points must
be observed when installing the unit.
• Unit must be lifted by the four lifting holes located at the
base frame corners.
• Lifting cables should be attached to the unit with shackles.
• The distance between the crane hook and the top of the
unit must not be less than 60".
• Two spreader bars must span over the unit to prevent
damage to the cabinet by the lift cables. Spreader bars
must be of sufficient length so that cables do not come
in contact with the unit during transport. Remove wood
struts mounted beneath unit base frame before setting
unit on roof curb. These struts are intended to protect
unit base frame from fork lift damage. Removal is ac-
complished by extracting the sheet metal retainers and
pulling the struts through the base of the unit. Refer to
rigging label on the unit.
IMPORTANT: If using with roof curb, ductwork should be attached
to the curb prior to installing the unit. Ductwork dimensions are
shown in Roof Curb Installation Instructions.
Refer to the Roof Curb Installation Instructions for proper curb
installation. Curbing must be installed in compliance with the Na-
tional Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit,
center of gravity will cause condenser end to be lower than supply
air end.
