INTRODUCTION

Merco Thermal Shelves are designed to keep prepared foods
hot in kitchen work areas, server pick-up stations, or customer

durability, attractive appearance, and optimum performance.
Every unit is inspected and tested thoroughly prior to shipment.

IMPORTANT SAFETY INFORMATION

WARNING

NOTICE

CAUTION

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.

• Turn power switch OFF, unplug power cord, 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 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.

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

• 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.

Make sure food product has been heated to the proper food­safe 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.

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 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 unit will get
hot. Use caution when touching these areas.

Locate unit at proper counter height in an area that is
convenient for use. The location should be level to prevent
unit or its contents from falling accidentally and strong
enough to support the weight of unit and contents.

Do not operate built-in models without control box
mounted properly as described in the installation
instructions.

The National Sanitation Foundation (NSF) requires that
units over 36″ (914 mm) in width or weighing more than 80
lbs. (36 kg) either be sealed to or raised above the
installation surface. If unit cannot be sealed at the point of
use, 4″ (102 mm) legs are included to allow for proper
cleaning access below unit.

Unit is recommended for use in metallic countertops.
Damage to non-metallic countertop material caused by
heat generated from this equipment is not covered under
unit warranty. For other surfaces, verify that the material is
suitable for temperatures up to 200°F (93°C).

Built-in units must not have a setpoint temperature higher
than 200°F (93°C). Temperatures exceeding 200°F (93°C)
will damage unit and void warranty.

Do not modify wiring or cut thermostat capillary wire on
control box to increase remote mounting distance. Cutting
thermostat capillary wire will cause unit to overheat and
may damage unit as well as surrounding countertop.

Do not use excessive force when tightening mounting
screws on built-in units. This may damage unit and/or
countertop.

Do not lay unit on the side with the control panel. Damage
to 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.

TS2 Model

The Thermal Shelf is ideal for pass-through areas, buffet lines,
or as a heated work shelf. It features an illuminated Power
On/Off switch, 80° to 200°F (27° to 93°C) adjustable thermostat,
and 6′ (1829 mm) power cord with plug. Surface mounted,
blanket-type foil elements distribute heat under the entire
stainless steel or hardcoat aluminum surface.

All TS2 models are shipped from the factory completely
assembled and ready for use.

Figure 1. TS2 Model

TS2-B Models

TS2-B Built-In Thermal Shelves have either a hardcoat
aluminum or stainless steel surface and a blanket-type foil
element for uniform heat distribution. Ideal for server-to­customer pass-through areas, buffet/ cafeteria lines, and other
self-service areas.

A 36″ (914 mm) flexible conduit channels the power lines from
the shelf to a remote control box. The control box comes with a
control thermostat with a range of 80° to 200°F (27° to 93°C),
an illuminated POWER On/Off (I/O) switch, and mounting
brackets. The attached control box can be located up to 36″
(914 mm) from the unit. A 6′ (1829 mm) cord and plug is
attached to the control box.

TS2-B Thermal Shelves are available with two different styles of
tops — recessed top and flat top. Recessed top models have a
3/4″ (19 mm) flanged edge that allows the unit to drop into a
countertop opening for recessed mounting. Flat top models
have a single piece, flat top that rests on the countertop for a
continuous, “flush” look with the countertop. The shelves are
easy to clean with a soft damp cloth or non-abrasive cleaner. All
TS2-B models are shipped from the factory completely
assembled and ready for use.
