DANGER
Improper installation, adjustment, maintenance or service, and unauthorized alterations or
modifications can cause property damage, injury, or death. Read the installation, operating and
service instructions thoroughly before installing or servicing this equipment.
DANGER
The front ledge of the fryer is not a step. Do not stand on the fryer. Serious injury can result
from slips or contact with the hot oil.
DANGER
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any
other appliance.
DANGER
The crumb tray in fryers equipped with a filter system must be emptied into a fireproof container
at the end of frying operations each day. Some food particles can spontaneously combust if left
soaking in certain shortening material. Additional information can be obtained in the filtration
manual included with the system.
WARNING
No structural material on the fryer should be altered or removed to accommodate placement of
the fryer under a hood. Questions? Call the Frymaster/Dean Service Hotline at 1-800-551-8633.
WARNING
Do not bang fry baskets or other utensils on the fryer’s joiner strip. The strip is present to seal
the joint between the frypot. Banging fry baskets on the strip to dislodge shortening will distort
the strip, adversely affecting its fit. It is designed for a tight fit and should only be removed for
cleaning.
