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.

• Remote mounted control enclosure must be mounted
on a vertical wall and installed in vertical position.
Mounting control enclosure in horizontal position may
result in collection of liquids and lead to an electric
shock.

• 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 jet­clean 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.

• 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.

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.

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 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; fax [phone]; or
International fax [phone].

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

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

Do not operate built-in models without the trim mounting
ring and the 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.

Make sure to clean and sanitize stone surface properly
after deep cleaning the surface using abrasives and before
placing food product on unit.

Unit is designed and recommended for use in or on
metallic countertops. Damage to any countertop material
caused by heat generated from Hatco equipment is not
covered under the Hatco warranty. Verify with the
manufacturer that the material is suitable for prolonged
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 on control
box to increase remote mounting distance. Cutting
thermostat capillary will cause unit to overheat and may
damage unit as well as surrounding countertop.

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

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

Do not drag or slide unit when moving or installing.
Carefully lift unit to prevent the rubber feet from tearing off.

If weight on shelf exceeds 50 lbs. (23 kg), a deflection up to
5/32″ (4 mm) is possible. If weight on shelf exceeds 100 lbs.
(45 kg), a deflection of 1/4″ (6 mm) is possible. Shelf is not
guaranteed if weight on shelf exceeds 150 lbs. (68 kg). All
weight must be distributed evenly across entire shelf.

INSTALLATION

General

Use the following procedures to install the GRSS, GRSSR, and
GRSSB units.

ELECTRIC SHOCK HAZARD: Unit is not weatherproof.
Locate the unit indoors where the ambient air temperature
is a minimum of 70°F (21°C).

FIRE HAZARD: Locate unit a minimum of 1″ (25 mm) from
combustible walls and materials. If safe distances are not
maintained, combustion or discoloration could occur.

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

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.

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

GRSS and GRSSR Models

1. Remove the unit from the box.

NOTE: To prevent delay in obtaining warranty coverage,

complete online warranty registration. See the
IMPORTANT OWNER INFORMATION section for
details.

2. Remove tape and protective packaging from all surfaces of
unit.

NOTE: If 4″ (102 mm) legs are required, refer to the OPTIONS

AND ACCESSORIES section in this manual for
installation instructions. 4″ legs are included with
models greater than 36″ (914 mm) in width.

3. Place the unit in the desired location.

• Locate the unit in an area where the ambient air
temperature is constant and a minimum of 70°F (21°C).
Avoid areas that may be subject to active air
movements or currents (i.e., near exhaust fans/hoods,
air conditioning ducts, and exterior doors).

• Make sure the unit is at the proper counter height in an

area convenient for use.

• Make sure the countertop is level and strong enough to

support the weight of the unit and food product.

• Make sure all the feet on the bottom of the unit are
positioned securely on the countertop.

4. Install any accessories that came with the unit. Refer to the
OPTIONS AND ACCESSORIES section for details.

GRSSB Models

1. Remove the unit from the box.

NOTE: To prevent delay in obtaining warranty coverage, complete

online warranty registration. See the IMPORTANT

OWNER INFORMATION section for details.

2. Remove tape and protective packaging from all surfaces
of unit.

Unit is designed and recommended for use in or on
metallic countertops. Damage to any countertop material
caused by heat generated from Hatco equipment is not
covered under the Hatco warranty. Verify with the
manufacturer that the material is suitable for prolonged
temperatures up to 200°F (93°C).

3. Prepare the countertop opening. Refer to the “GRSSB
Countertop Cutout Chart” in this section for recommended
countertop cutout dimensions.

4. Apply a bead of National Sanitation Foundation (NSF)­approved sealant on the top edge of the countertop cutout
and the underside of the trim mounting ring. The sealant
must be rated for use at a minimum temperature of 250° F
(121° C).

5. Place the unit into the countertop opening.

6. Remove any excess sealant.

7. Locate the remote control box assembly in an area that is
convenient for operation. If desired or necessary, the
control box can be mounted in a semi-remote location.

• Remove the control box from the bottom of the unit.

• If necessary, remove the end brackets from the control
box, rotate/reposition, and re-secure to the control box.

• The control box can be panel, surface, or under counter
mounted.

• The distance the control box can be mounted from the unit
is determined by the 3’ (914 mm) conduit (optional conduit
lengths of 6’ [1829 mm] and 10’ [3048 mm] are also
available with electronic controls). Do not pull the conduit
tight to increase the mounting distance. The conduit
should have some slack after the control box is mounted.

NOTE: The remote control box should be mounted using

screws with a 1/4″ (6 mm) minimum diameter screw
