INSTALLATION
General
Use the following procedures to install the GRSS, GRSSR, and
GRSSB units.
WARNING
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.
CAUTION
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.
NOTICE
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.
NOTE: Refer to the OPTIONS AND ACCESSORIES section
for installation and operation information for GRSSB
units equipped with remote mounted control panel.
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
head inserted through the keyholes located on the
mounting brackets. The remote control box is to be
readily removable—not permanently mounted.
