Shipment and Receiving
Handle your equipment with caution. Some fans are pro-
vided with lifting lugs or holes for easy handling. Others
must be handled using nylon straps which protect the

Fans should be lifted by using straps around the fan
housing only. DO NOT LIFT FANS BY THE MOTOR,

If fans are stored for any length of time, they should
be stored in a clean, dry location to prevent rust and
