Manufacturer’s Introduction
The Duke Dry Channel Holding Unit was
developed to provide the market with a more
efficient method of keeping food warm. This
equipment uses electronically controlled heaters to
warm aluminum channels to a user programmable
temperature. Advantages over steam tables
include lower energy and maintenance costs.
Unpacking Unit:
• Inspect the shipping carton and/or
container, carefully noting any exterior
damage on the delivery receipt, which must
also be signed by the driver/delivery
person.
• Unpack and inspect for any damage, which
was not evident on the outside of the
shipping container (concealed damage).
Contact the carrier immediately and file a
damage claim with them. Save all packing
materials when filing a claim. Freight
damage claims are the responsibility of the
purchaser and are not covered by the
warranty.
• Do not attempt to use the unit if
damaged.
If unit has been stored in extremely cold area, wait
a few hours before connecting power.
