is evenly distributed throughout the heavy gauge stainless
steel construction to assure hot food. The design allows for
easy maintenance and durable performance. The standard unit
is Underwriters Laboratory (UL) approved and equipped with a
remote control enclosure. An optional UL recognized (UR) unit

most components assembled and ready for use. Use the
following procedures to install the unit.
WARNING
ELECTRIC SHOCK HAZARD: Unit is not weatherproof.
Locate unit indoors where ambient air temperature is a
minimum of 70°F (21°C).
FIRE HAZARD:
 • Installunitwithaminimumof3-1/2″(89mm)ofspace
from bottom of unit to all combustible surfaces to
prevent combustion.
• Unit must be installed using ribbon putty gasket
between the unit and the installation surface per
installation instructions.
This unit must be installed by qualified, trained installers.
Installation must conform to all local electrical and
plumbing codes. Check with local plumbing and electrical
inspectors for proper procedures and codes.
CAUTION
Locate the unit at the proper counter height in an area
that is convenient for use. The location should be strong
enough to support the weight of the unit and contents.
NOTICE
Units are voltage-specific. Refer to specification label for
electrical requirements before beginning installation.
Do not locate unit in an area subject to excessive
temperatures or grease from grills, fryers, etc. Excessive
temperatures could cause damage to the unit.
Unit is designed and recommended for use in or on
metallic countertops. Damage to any countertop material
is not covered under the Hatco warranty. For other
surfaces, verify with manufacturer that material is suitable
forprolongedtemperaturesupto200°F(93°C).
NOTICE
Remote mounted control panels must have a minimum
6″ (152 mm) clearance from unit (not to exceed 72″
[1829mm]).Mountingcontrolpanelclosermaycauseheat
damage to electrical system in control panel.
Damage to any countertop material caused by heat
generated from Hatco equipment is not covered under
the Hatco warranty. Contact the manufacturer of the
countertop material for application information.
NOTE: All Built-In Heated Wells require the control enclosure
be remote mounted in the vertical position.
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: A qualified electrician is recommended for connecting
the Built-In Heated Well units to a power source. A
qualified plumber is recommended for connecting
drain.
3. Install the unit in the desired location. Use the appropriate
procedure in this section for combustible or non-
combustible countertops.
IMPORTANT NOTE:
For bottom mount units, see “Installing a Bottom Mount
Unit” in this section or “Mounting Bracket for Bottom Mount
Units” in the OPTIONS AND ACCESSORIES section before
performing any countertop cutouts.
4. Install the remote control enclosure (refer to the procedure
in this section).

WARNING
FIRE HAZARD:
• Hatco mounting flange kits must be used when
mounting unit in a combustible countertop.
• Unit must be installed using ribbon putty gasket
between the unit and the installation surface per
installation instructions.
NOTE: Cut the opening for both the mounting flange/unit and
the control enclosure before placing the assembly into
the countertop opening.
NOTE: Make sure the installation location provides enough
room for the remote control enclosure, electrical
connections, and plumbing connections.
1. Cut the appropriate opening for the mounting flange into
the countertop. Refer to “Combustible Countertop Cutout
Chart (for Unit/Mounting Kit)” in this section.
2. Cut the appropriate opening for the control enclosure.
Refer to “Control Enclosure Cutout Dimensions” in this
section.
3. Place ribbon putty gasket around the cutout edge of the
countertop. Make sure the ribbon putty gasket overhangs
the cutout edge or seal the unit with silicone adhesive.
NOTE: A roll of ribbon putty gasket material is supplied with the
unit.

INSTALLATION
Installing a Remote Control Enclosure
WARNING
ELECTRIC SHOCK HAZARD:
• The remote control enclosure must be mounted on
a vertical wall and installed in the vertical position.
Mounting the control enclosure in the horizontal position
may result in the collection of liquids and lead to an
electric shock.
• Operating voltage of remote control enclosure water valve
exceeds 50 V (extra low voltage). Enclosure is marked
with the following hazard identification symbol:
NOTE: A qualified electrician is recommended for connecting
the unit to a power source. A qualified plumber is
recommended for connecting drain(s) and Auto-Fill.
1. Cut and drill the appropriate holes in the mounting surface.
Refer to the “Control Enclosure Cutout Dimensions” below
for the cutout dimensions for each control enclosure.
2. Remove the trim cover from the control enclosure assembly.
3. Position the control enclosure into the opening through the
backside.
4. Secure the control enclosure to the mounting surface
using screws (#8 sheet metal screws supplied).
5. Connect the proper power source to the mounted remote
control enclosure.
• For corded units, plug power cord into a properly
grounded electrical receptacle of the correct voltage,
size, and plug configuration. See the SPECIFICATIONS
section for details.
• For hardwired units, have a qualified electrician make
the appropriate electrical connections.
NOTE: Standard, UL approved hardwired units are equipped
with a 36″ (914 mm) flexible conduit connected to the
control enclosure.
6. Connect the water supply to the optional Auto-Fill system,
if equipped. Refer to the “Installing an Auto-Fill Unit”
procedure in this section.
7. Reinstall the trim cover.

INSTALLATION
Installing an Auto-Fill Unit
The side mounted Auto-Fill option connects the on-site water
supply through the control panel to an Auto-Fill fitting on the
side of the well enclosure. Use the following procedure to install
a unit equipped with the side mounted Auto-Fill option.
NOTE: The Plumbing Kit that comes with this unit includes the
following parts: street elbow, back-flow preventer valve,
fill tube hose, and hose clamps.
CAUTION
Auto-Fill units must be installed with adequate backflow
protection and must conform with federal, state, and local codes.
NOTICE
Auto-fill units supplied with water from a reverse osmosis
(RO) system (or similiar water filtration system) must be
installed with an operating reminerialization sytem to ensure
proper operation. Failure to do so may cause unit to overfill.
Damage caused by overfilling is not covered under warranty.
Drain sealants must have temperature rating of 500°F or
higher. Incoming water pipes must be FDA compliant for
potable water.
1. Connect the street elbow to the Auto-Fill fitting located on
the outside of the well. Replace the fill tube hose on fitting.
NOTE: The fill tube hose may need to be removed from the
Plumbing Kit for ease of installation.
2. Connect the fill tube hose to the fill valve nipple in the control
enclosure and secure using the hose clamp. (Disassemble
the control enclosure trim cover to access the nipple.)

Installing a Bottom Mount Unit
Installation of a bottom mount unit requires custom fabrication of
the countertop by a qualified and experienced installer. Use the
following information as guidelines for one method of installing a
bottom mount unit. Refer to the OPTIONS AND ACCESSORIES
section for installation with an optional mounting bracket.
• Create the countertop cutout with turned-down flanges on
all four sides. These flanges should be positioned on the
inside of the well for installation.
