INSTALLATION INSTRUCTIONS

A. Qualified Personnel

These installation instructions are for the use of

qualified installation and service personnel
only. Installation or service by other than

• Check for concealed damage. The carrier
must be notified within fifteen (15) days of
the delivery of the unit and the crate and all
packaging materials must be retained for
inspection.

 Check compressor compartment housing

and visually inspect refrigeration package.
Check that refrigeration lines are secure
and the base is still intact.

Duke Manufacturing Co. cannot assume liability
for loss or damage suffered in transit. The
carrier assumes full responsibility for delivery in

B. Delivery and Inspection

Duke Manufacturing Co. does everything within

• Look over the shipping container, carefully

noting any exterior damage on the delivery
receipt, which must also be signed by the
driver/ delivery person.

C. Placement

• HANDLING – The units are very heavy and
may require the use of moving equipment.
Consult with your local restaurant
