similar qualifications.
• This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.
• Use only Genuine Hatco Replacement Parts when
service is required. Failure to use Genuine Hatco
Replacement Parts will void all warranties and may
subject operators of the equipment to hazardous
electrical voltage, resulting in electrical shock or burn.
Genuine Hatco Replacement Parts are specified to
operate safely in the environments in which they are
used. Some aftermarket or generic replacement parts
do not have the characteristics that will allow them to
operate safely in Hatco equipment.
FIRE HAZARD: Locate unit a minimum of 1″ (25 mm) from
combustible walls and materials. If safe distances are not
maintained, discoloration or combustion could occur.
Make sure food product has been heated to the proper
food-safe temperature before placing on the unit. Failure
to heat food product properly may result in serious health
risks. This unit is for holding preheated food product only.
Make sure all operators have been instructed on the safe
and proper use of the unit.
This unit is not intended for use by children or persons
with reduced physical, sensory, or mental capabilities.

Sanitation Foundation (NSF) standards and are specifically
designed for food holding areas. Breakage of light bulbs
not specially coated could result in personal injury and/or
food contamination.
This unit has no “user-serviceable” parts. If service

Service Agent or contact the Hatco Service Department at
414-671-6350.
CAUTION

bottomed pans, or drop anything on hardcoat surface.
Scratching or breakage may occur. Damage to hardcoat
surface caused by misuse is not covered under warranty.

scratch the finish of the unit, marring its appearance and
making it susceptible to soil accumulation.
IMPORTANT—DO NOT use paper towel or glass cleaner to
clean plastic surfaces such as sneeze guards and flip-up
doors. Paper towel and glass cleaner may scratch the
material. Wipe off plastic surfaces using a soft, clean, and
damp cloth.
