INTRODUCTION

Merco Heated Drawers are designed to keep foods at optimum
serving temperatures without affecting quality. They are built
for tough kitchen duty with rugged stainless steel construction,
heavy-duty hardware, stainless steel slides, and positive­closing drawers. Heated Drawers keep everything from meat
to vegetables to rolls hot and flavor-fresh until served.

On multiple drawer units, each drawer features individual
controls for holding a wider variety of hot foods during peak
serving periods.

Merco Heated Drawers are products of extensive research and
field testing. The materials used were selected for maximum
durability, attractive appearance, and optimum performance.
Every unit is inspected and tested thoroughly prior to shipment.

This manual provides the installation, safety, and operating
instructions for Heated Drawers. Merco recommends all
installation, operating, and safety instructions appearing in this
manual be read prior to installation or operation of the unit.

Safety information that appears in this manual is identified by
the following signal word panels:

WARNING indicates a hazardous situation which, if not
avoided, could result in death or serious injury.

CAUTION indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.

WARNING

Read the following important safety information before using this equipment to avoid serious injury or death and
to avoid damage to equipment or property.

ELECTRIC SHOCK HAZARD:

• Plug unit into a properly grounded electrical receptacle
of the correct voltage, size, and plug configuration. If
plug and receptacle do not match, contact a qualified
electrician to determine and install the proper voltage
and size electrical receptacle.

• Built-in units must be installed by a qualified
electrician. Installation must conform to all local
electrical codes. Installation by unqualified personnel
will void the unit warranty and may lead to electric
shock or burn, as well as damage to unit and/or its
surroundings.

• Turn power switch OFF, unplug power cord/turn off
power at circuit breaker, and allow unit to cool before
performing any maintenance or cleaning.

• 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).

• Do not steam clean or use excessive water on the unit.

• This unit is not “jet-proof” construction. Do not use jet­clean spray to clean this 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 Merco, a Factory
Authorized Service Agent, or a person with similar
qualifications.

• Do not clean unit when it is energized or hot.

• Do not allow liquids to spill into the unit.

• Use only Original Equipment Manufacturer (OEM)
Replacement Parts when service is required. Failure to
use OEM Replacement Parts will void all warranties and
may subject operators of the equipment to hazardous
electrical voltage, resulting in electrical shock or burn.
OEM 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 Merco 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.

• Do not use harsh chemicals such as bleach (or cleaners
containing bleach), oven cleaners, or flammable
cleaning solutions to clean this unit.

Make sure food product has been heated to the proper
food-safe temperature before placing in unit. Failure to heat
food product properly may result in serious health risks.
This unit is for holding preheated food product only.

This unit is not intended for use by children or persons
with reduced physical, sensory, or mental capabilities.
Ensure proper supervision of children and keep them away
from the unit.

Make sure all operators have been instructed on the safe
and proper use of the unit.

This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.

This unit has no “user-serviceable” parts. If service is
required on this unit, contact a Factory Authorized Service
Agent or contact the Merco Service Department at
800-506-9565.

BURN HAZARD:

• Some exterior surfaces on the unit will get hot. Use
caution when touching these areas.

• Use caution when opening drawer. Hot air escapes
when drawer is open.

Locate unit in an area that is convenient for use. The
location should be level and strong enough to support the
weight of the unit and contents.

Do not lay unit on the front or back side. Damage to the
unit could occur.

Use non-abrasive cleaners only. Abrasive cleaners could
scratch the finish of the unit, marring its appearance and
making it susceptible to soil accumulation.
