Installation; Grs Models; Grsb And Grsbf Models - Hatco GRS-18 Installation And Operating Manual

General
Use the following procedures to install the GRS,
GRSB, and GRSBF units.
WARNING
FIRE HAZARD: Locate the 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 the unit at the proper counter height in
an area that is convenient for use. The location
should be level to prevent the 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 heated shelf units over 36"
(914 mm) in length or weighing more than
80 lbs. (36 kg) either be sealed to or raised
above the installation surface. If this unit cannot
be sealed at the point of use, 4" (102 mm) legs
are included to allow for proper cleaning access
below unit. Refer to the ACCESSORIES section
for installation instructions.

GRS Models

1. Remove the unit from the carton and place it
upside down on the cardboard.
2. Install the four feet into the corner holes on the
base. Tighten securely, but do not over-tighten.
NOTE: If 4" (102 mm) legs are required, refer to the
ACCESSORIES section in this manual for
installation instructions.
3. Place one rubber boot over each metal foot.
(for 1" [25 mm] feet only.)
4. Turn unit upright, and place unit in the desired
location. Make sure all the feet on the bottom of
the unit are positioned securely on the
countertop.

2. Remove and save the four bracket screws from
the underside of the unit (see Figure 8).
NOTE: The control box may be moved to the most
convenient location on the underside of the
unit. For semi-remote installations, leave
the control box in place until the unit is
placed into the countertop (see Figure 11).
This unit is recommended for use in metallic
countertops. Damage to non-metallic countertop
material caused by heat generated from Hatco
equipment is not covered under the Hatco
warranty. For other surfaces, verify that the
material is suitable for temperatures up to 200° F
(93° C)
3. Prepare countertop opening. Refer to the
"Countertop Cutout" charts on the following
pages for recommended countertop cutout
dimensions.
4. Apply a bead of NSF-approved sealant between
the countertop material and the mounting flange
on the unit. 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. Assemble the Z-brackets to the underside of the
unit using the four bracket screws removed
earlier in this procedure (see Figures 9 and 10).
NOTE: Units 48" (1219 mm) or longer require two
additional Z-brackets to be installed midway
along the front and rear of the unit.
