In the event it is necessary to repack the equipment 

for shipment, the equipment must be packed exactly 

as shown below. It is very important that the four feet 

are attached to the bottom of the equipment. This will 

ensure the proper equipment location on the bottom 

foam pad. Failure to do this will result in shipping 

damage.

To protect the tubes during shippment, the Foam 

Insert removed from the MC2152 needs to be re-in-

serted. Follow the unpacking instructions on pages 4-5 

in the reverse order.

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, refer to page 2. Please 

see the Part List for the correct part numbers.
