COOK Laboratory Exhaust - Manual (Page 7)

3.2 Rigging a Multiple Section Unit
Note: Use all of the lifting points provided on the equipment.
Loren Cook will not be responsible for damages incurred from not using all of the lifting points.
Remove all of the sheet metal covers marked “Remove—For Shipping Purpose only” that may
interfere with the installation. When the unit is lifted, check the bottom for truck supports.
These supports will be 2” x 2” tubing screwed to the bottom of the unit to provide support to
units whose width exceeds that of the trailer that it was shipped on. Remove these as the unit is
lifted as they may interfere with the installation.
If the equipment is to set on a curb, install the curb gasket to the curb only. Do not apply curb
gasket to the unit
’s base frame. Apply the demount gasket to the equipment. Do not double
gasket the sectional abutment. Apply the gasket to the face of only one of the mating sections.
Be sure that gasket is applied to the perimeter of the cabinet and also around the separate air
passages, which may exist on some units (i.e. units with heat reclaim, exhaust air, heat wheels,
multi-zone units, etc.) Demount
gasket is 3/8” x 1” and is also supplied with the equipment.
Select the first section to be set and prepare for lifting. Rig into place being careful to place it
square and in line of the curb or support base. Once the first section is in place, secure it to the
supporting structure. When the second and continuing sections are set, they will be drawn to
the previous section. That is why it is necessary to secure the first section before proceeding. It
is critical that each section is rigged as level a possible.
