Packing Instructions
In the event it is necessary to repack the equipment for
shipment, the equipment must be packed exactly as
shown below.
Note:
It is very important that the four plastic feet are
attached to the bottom of the equipment. This will
ensure the proper equipment location on the bottom
pad. Failure to do this will result in shipping damage.
Use the original shipping carton and interior parts
only if they are all in good serviceable condition.
If a shipping carton or any of the interior part(s) are
needed, please call or write Customer Service Depart-
ment of McIntosh Laboratory.
