COOK Laboratory Exhaust - Manual (Page 4)

2.1.2 Long-Term Storage
Long-term storage is considered to be any period longer than six (6) months from date of
shipment. If long-term storage is anticipated, contact the Loren Cook sales office at time of
order entry for the proper instruction for long-term storage. It is mandatory that a detailed record
be maintained during this long-term storage period, such as, but not limited to, proper sealing of
the cabinet, rotation of the blowers and bearings and protection of all motors from moisture.
Note: Under certain conditions, it may be necessary to remove the motors from the unit and/or
add heat to the motor. This record must be available to Loren Cook should a failure occur
during the warranty period. There is a time limit of one year from date of shipment that any unit
may be kept in long-term storage. At the end of the one year period, the unit must be in
operation.
Note: Failure to perform the long-term storage requirements and properly log these required
procedures will void the warranty.

Rigging the Equipment
Decide which section of the equipment that would be most advantageous to set first. You may
need to consult the rigger in this decision. Items to be considered would be the reach of the
pick, configuration of the building and obstructions on the roof. It is important that an
experienced and reliable rigger be selected to handle unloading and final placement of the
equipment. Weight of the unit or of its individual sections is the key consideration. This will
determine the size of the crane needed to execute the lift. The rigger should have spreader
bars capable of spanning both the width and length of the equipment. The rigging should
employ some method that allows self-leveling of the load. All of the cables tied to the
equipment should be reasonable confirmed to have the same stress as the section being lifted.
An imbalance or unleveled lift will damage piping and components installed in the equipment
and will not allow proper alignment of the sections as they are lowered into position.
