IMPORTANT SAFETY INFORMATION
MODEL DESIGNATION
CAUTIONS
To avoid any injury or damage locate the unit
at the proper counter height, in an area that
is convenient for use. The location should be
level and strong enough to support the
weight of the unit and food product.
Unit is not weatherproof. For safe and proper
operation the unit must be located indoors
where the ambient air temperature is a
minimum of 70°F (21°C) and a maximum of
85°F (29°C).
To avoid injury or damage to the unit DO NOT
clean the unit while it contains any food
product. Remove food product and allow
unit to cool completely before cleaning.
Standard and approved manufacturing oils
and insulation binders will smoke up to 60
minutes during initial start-up. This is a
temporary condition. To assure safe
operation, operate unit without food product
until smoke dissipates.
CAUTIONS
Do not locate the Built-In Heated Well in an
area subject to excessive temperatures or
grease from grills, fryers, etc. Excessive
temperatures could cause damage to the
unit.
Damage to countertop material such as
Corian®and similar products caused by heat
generated from Hatco equipment is not
covered under the Hatco warranty. Contact
the manufacturer of the base material for
application information.
To avoid damage to the unit, do not use
steel wool for cleaning. Steel wool will
scratch the finish.
To assure proper operation the remote
mounted control panel must be installed in
the vertical position.
Use only non-abrasive cleaners. Abrasive
cleaners could scratch the finish of your
unit marring its appearance and making it
susceptible to soil accumulation.

INSTALLATION
UNPACKING
Built-In Heated Well units are shipped from the
factory with most components assembled and ready
for use.
All Built-In Heated Wells require the control panel be
remote mounted.
NOTE: Drain models (“D” in the model designation)
require installation of the drain assembly after the
unit is installed into the countertop.

WARNING
To avoid any injury or damage Hatco mounting
kits must be used when mounting unit in a
combustible countertop.
NOTE: Cut opening for both the unit and control
panel before placing unit into countertop opening.
NOTE: Top Mount, HWB-FUL Series, insulated
models (“I” in the Model Designation) cannot be
installed into mounting flange.
1. Cut appropriate opening in countertop.
(See Figure 12 for size requirements.)
2. Cut appropriate opening for control panel.
(See Figure 14 for size requirements.)
3. Place gasket putty around cutout edge. Make
sure the gasket putty overhangs the cutout edge
or seal unit with silicone adhesive.
4. Place mounting flange into countertop opening.
5. Secure mounting flange tabs to edge or
underside of combustible countertop using
appropriate hardware. (Mounting hardware not
provided.) (See Figure 9.)
NOTE: For underside mounting, tabs on mounting
flange must be bent to underside of countertop.
6. Place gasket putty around cutout in mounting
flange. Make sure the gasket putty overhangs
the flange or seal unit with silicone adhesive.
7. Place the unit into the countertop opening.
8. Use a screwdriver to rotate the EZ locking
mounting system on the Built-In Heated Well
outward, to secure the unit from the underside of
the mounting flange. Twist as many tabs as
needed to secure unit to mounting flange.
(See Figure 10.)
9. Using a razor, carefully trim the excess gasket
putty material and remove.

GENERAL WARNING
Some exterior surfaces on the unit will get hot.
Use caution when touching these areas to avoid
injury.
WARNING
To avoid any injury or damage to the unit turn
unit off when filling with water and avoid
splashing.
WARNING
Do not use Heated Well to melt or hold ice.
Doing so may cause condensation, an electrical
hazard, personnel injury, or damage to the unit.
Damage caused by condensation is not covered
by warranty.
CAUTION
Unit is not weatherproof. For safe and proper
operation the unit must be located indoors
where the ambient air temperature is a minimum
of 70°F (21°C) and a maximum of 85°F (29°C).
CAUTION
Standard and approved manufacturing oils and
insulation binders will smoke up to 60 minutes
during initial start-up. This is a temporary
condition. To assure safe operation, operate unit
without food product until smoke dissipates.
Hatco Built-In Heated Wells are designed for WET
or DRY operation.
NOTE: Built-In Heated Wells cannot be used wet-to-
dry or dry-to-wet unless the unit has been allowed to
cool down to room temperature before changing the
operation.
We recommend wet operation for consistent food
heating.
If the unit is operating wet and is allowed to run dry,
turn it off and allow to cool before adding water.
POWER ON/OFF
Place the On/Off switch in the “ON” position. The
indicator light glows when the unit is on.
(See Figure 16.)
Thermostat Control Knob On/Off Switch
TEMPERATURE CONTROL
Turn thermostat control knob to adjust the
temperature of the Built-In Heated Well to the
desired safe food temperature.
