electrician to determine and install the proper voltage
and size electrical receptacle.
• Turn OFF power switch, unplug power cord, and
allow unit to cool before performing any cleaning,
adjustments, or maintenance.
• DO NOT submerge or saturate with water. Unit is not
waterproof. Do not operate if unit has been submerged
or saturated with water.
• Unit is not weatherproof. Locate unit indoors where
ambient air temperature is a minimum of 70°F (21°C).
• This unit is not “jet-proof” construction. Do not use
jet-clean spray to clean this unit.
• Do not steam clean or use excessive water on unit.
• Do not pull unit by power cord.
• Discontinue use if power cord is frayed or worn.
• Do not attempt to repair or replace a damaged
power cord. The cord must be replaced by Hatco, an
Authorized Hatco Service Agent, or a person with
similar qualifications.
• This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.
• Remote control enclosure must be mounted on vertical
wall and installed in vertical position. Mounting remote
control enclosure in horizontal position may result in
collection of liquids and lead to electric shock.
• 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.

This unit has no “user-serviceable” parts. If service
is required on this unit, contact an Authorized Hatco
Service Agent or contact the Hatco Service Department at
800-558-0607 or 414-671-6350.
CAUTION
BURN HAZARD: Some exterior surfaces on unit will get
hot. Use caution when touching these areas.
