INTRODUCTION

Hatco Modular Built-In Heated Wells are specially designed to
hold heated foods at safe serving temperatures. Designed for
dry or wet applications, the wells are available in a variety of
pan combinations — all heated with a long-life heating element
that is covered by a 2 year part warranty. The metal sheathed
heating element is controlled by a remote thermostat. Heat is
distributed evenly throughout the heavy gauge stainless steel
construction to ensure hot food. The design allows for easy
maintenance and durable performance. Standard units are UL
approved and equipped with a remote control enclosure.

Units are equipped with EZ lock mounting hardware, mounting
studs, or pre-drilled mounting holes. Controls include individual
lighted power switches and thermostat controls that retain
temperature settings. One year parts and on-site labor warranty
is standard.

Installing a Remote Control Enclosure

Remote control enclosures must be mounted on the front of the
unit to ensure the controls correspond with the correct wells
(the front of the unit is the side the conduit enters under the
unit). Remote control enclosures cannot be rewired and must
be installed in the proper location.

NOTE: A qualified electrician should connect the unit(s) to a

power source. A qualified plumber should connect the
water supply and drain(s).

NOTE: Refer to the “Side Mounted Auto-Fill” or “Bottom

Mounted Auto-Fill” procedure in the OPTIONS AND
ACCESSORIES section before installing a Remote
Control Enclosure.

1. Cut and drill the appropriate holes in the mounting surface.

ELECTRIC SHOCK HAZARD:

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

Refer to the “Control Enclosure Cutout Dimensions” chart
below for the cutout dimensions for each control enclosure.

• The cutout depth required for all control enclosures is
5″ (127 mm).

• Make sure to have enough space inside the cutout if
installing with conduit on the side of the control
enclosure.

• For units with two control enclosures: If the unit is
equipped with Auto-Fill, each enclosure cutout size will
be different (see chart below).

General

Use the following procedures to operate the Modular Built-In
Heated Wells.

Read all safety messages in the Important Safety
Information section before operating this equipment.

ELECTRIC SHOCK HAZARD:

• DO NOT use unit to melt or hold ice. Doing so may
cause condensation, creating an electrical hazard and
causing personal injury and/or damage to unit. Damage
caused by condensation is not covered by warranty.

• For units without Auto-Fill, turn off unit when filling with
water and avoid splashing.

Standard and approved manufacturing oils may smoke up to
30 minutes during initial startup. This is a temporary condition.
Operate unit without food product until smoke dissipates.

Unit must be allowed to cool down to room temperature
before changing from wet-to-dry or dry-to-wet operation.
Allowing unit to run dry during wet operation or adding
water during dry operation will damage unit.

Hatco Modular Built-In Heated Wells are designed for WET or
DRY operation. Hatco recommends wet operation for consistent
food heating. If the unit is operating wet and runs dry, turn it off
and allow to cool before adding water.

Startup

1. Prepare the heated wells for operation.

• If using the wells for dry operation, make sure the wells
are clean and dry.

• If using the wells for wet operation without Auto-Fill,
make sure the drain valve is closed (if equipped) and
manually fill the wells with hot tap water until the water
is a maximum of 1-1/4″ (32 mm) deep.

• If the unit is equipped with the Auto-Fill option, make sure
the drain valve is closed and go to step 2 in this
procedure.

2. Place an empty pan in the well or cover the well with a lid.
This step is recommended to speed up pre-heating and
reach operating temperature.

3. Move the Power I/O (on/off) switches to the I (on) position.
The indicator light on each switch glows when it is on.

• If the unit is equipped with the Auto-Fill option, the far
left Power I/O (on/off) switch will activate the Auto-Fill
system when it is moved to the I (on) position. The wells
will fill with water until the water reaches the water level
sensor in the far left well. During operation, the Auto-Fill
system will maintain the water level automatically using
the water level sensor.

NOTE: For HWBI-4, HWBI-5, and HWBI-6 units equipped with

Auto-Fill, turn on the left-hand control first, then turn on
the right-hand control.

4. Turn the Temperature Control Knobs to the desired safe
food temperature.

Hatco Corporation is not responsible for actual food
product serving temperature. It is the responsibility of the
user to ensure that food product is held and served at a
safe temperature.

5. Allow the unit to preheat for approximately 30 minutes.

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

Food Warming

Place the appropriate size food pans with pre-heated food
product into the heated wells.

• Always use a food pan. Do not place food directly into the
heated well.

• Stir thick food items frequently to keep food heated
uniformly.

• Keep pans covered to maintain food quality and
temperature.

Shutdown

1. Move the Power I/O (on/off) switches to the O (off) position.
The indicator light on the switches will shut off and the Auto­Fill system will be deactivated (if equipped).
