INSTALLATION AND STARTUP

WARNING:

Risk of personal injury

Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure could
result in personal injury and proper­ty damage.

IMPORTANT:

Power cord is 8' long

If necessary, contact a licensed
electrician to install an appropriate
20 amp electrical circuit with correct
NEMA receptacle.

DO NOT use an extension cord.

CAUTION:

Electrical Shock Hazard

The ground prong of the power

cord is part of a system designed to
protect you from electric shock in
the event of internal damage.

DO NOT cut off the large round
ground prong or twist a blade to fit
an existing receptacle.

IMPORTANT:
Not under warranty

Damage to unit due to being
connected to the wrong voltage or
phase is NOT covered by warranty.

WARNING:

Risk of personal injury

Unit is not waterproof, to avoid
electrical shock, keep unit from be­ing submerged in water. Do not
operate if unit has been in contact
with water.

LOCATION

For proper operation and maximum performance, locate the
unit in an ambient air temperature of 70ºF (21ºC).

Avoid placement in areas near exhaust fans or where there
are active air movements.

For safe operation and maximum performance, locate the
unit at least 2” from any wall or combustible material.

Unit must be on a solid level surface.

GROUNDING INSTRUCTIONS

This appliance is equipped with a cord having a grounding wire with
a grounding plug which must be plugged into an outlet that is
properly installed and grounded. In the event of an electrical short
circuit, grounding reduces the risk of electric shock by providing an
escape wire for the electric current.

WARNING—Improper use of the grounding can result in a risk
of electric shock. Consult a qualified electrician or service agent if

the grounding instructions are not completely understood, or if doubt
exists as to whether the appliance is properly grounded.

START UP

1. Prior to use, thoroughly clean the interior of the unit, per
the instructions in this manual. Familiarize yourself with
the controls.

2. Plug the power cord of the cabinet into a grounded outlet
with a electrical service according to the electrical infor­mation provided below. DO NOT MODIFY CORD PLUG.

3. Set POWER switch to the “ON” position.

4. Do not load product into the cabinet. Allow the heat to
remove any residual oils which may adhere to inside met­al surfaces. A slight emission of smoke is common dur­ing the first few hours of operation.

NORMAL OPERATION—HL1 & HL3 HB HEATED CABINETS

CAUTION:
HOT SURFACE

Inner and outer surfaces of
the unit will be very hot dur­ing and after operation.

Avoid touching the cabinet
when loading or removing
product.

Operating ranges:

- air temp: 90ºF-190ºF
(32°C - 88°C)

*For food safety reasons,
it is recommended that
the holding temperature
be set at 140°F (60°C) or
higher.

FIRST USE

Before using the cabinet, familiarize yourself with the heater con­trols. See page 9 for details. Plug the cabinet into a proven power
source. See electrical specifications on page 8.

HOLDING

1. Turn the cabinet on using the power switch located on the far left
side of the control panel. Once the switch is turned on, the
power indicator light will illuminate.

2. A water pan is provided in the base of the cabinet to provide a
small amount of passive humidity, if desired. Fill pan with clean
warm water. Check water level every 2 hours and refill as
needed. This step is optional; cabinet be also be operated
without water in the pan.

3. To adjust the temperature setting, rotate the HEAT dial clock­wise to increase temperature and counter-clockwise to decrease
temperature to the desired set point. Temperature dial settings
range from 1 to 10, with 1 being the lowest temperature and 10
being the highest temperature. HEAT cycle light will turn on and
off as the heat thermostat cycles.

4. Wait approximately 25 minutes for the cabinet to preheat. Digital

readout dial on right side of control panel will display actual
cabinet temperature*.

5. Load food pans into cabinet. NOTE: Follow all food safety guide­lines. Put hot, cooked food into the cabinet. This cabinet is not
intended to reheat food. Food must be cooked and at safe serv­ing temperature prior to being placed in the cabinet.

6. When removing items, start at the bottom and work up. This will

keep food hotter and eliminate spillage onto lower items.

NORMAL OPERATION—HL2 & HL4 HW HEATER PROOFERS

CAUTION:
HOT SURFACE

Inner and outer surfaces of
the unit will be very hot dur­ing and after operation.

Avoid touching the cabinet
when loading or removing
product.

Operating ranges:

- air temp: 90ºF-190ºF
(32°C to 88°C)

- humidity: 0-90%RH

Water reservoir:

When using the water reser­voir for humidified holding or
proofing, check water level
every 2 hours and refill if
needed.

CAUTION:
WATER HAZARD

A water trough is located at
the base of the cabinet to
collect and direct condensa­tion into black plastic con­densation pan below. Make
sure to periodically check
and empty the pan to avoid
overflow & slip hazard.

*For food safety reasons,
we recommend that the
holding temperature
should be set at or above
140°F (60°C).

FIRST USE

Before using the cabinet, familiarize yourself with the heater con­trols. See page 9 for details. Plug the cabinet into a proven power
source. See electrical specifications on page 8.

HOLDING

1. If humidity is desired, a water pan is located at the bottom of the

cabinet. This pan will provide active humidification up to 90%RH
(depending on temperature). Fill water pan with clean warm
water. NOTE: Cabinet may also be operated without water.

2. Turn the cabinet on using the power switch located on the far left

side of the control panel. Once the switch is turned on, the
power indicator light will illuminate.

3. To adjust the temperature setting, rotate the HEAT dial clock­wise to increase temperature and counter-clockwise to decrease
temperature to the desired set point. Temperature dial settings
range from 1 to 10, with 1 being the lowest temperature and 10
being the highest temperature.

4. To adjust humidity, rotate the humidity dial clockwise to

increase humidity and counter-clockwise to decrease humidity.
If humidity is not required, rotate dial counter-clockwise to the off
position (line up dot on knob with white hash mark on control
panel).

5. Wait approximately 25 minutes for the cabinet to preheat. Digital

readout dial on right side of control panel will display actual
cabinet temperature*.

6. Load food pans into cabinet. NOTE: Follow all food safety guide-

lines. Put hot, cooked food into the cabinet. This cabinet is not
intended to reheat food. Food must be cooked and at safe
serving temperature prior to being placed in the cabinet.

7. When removing items, start at the bottom and work up. This will

keep food hotter and eliminate spillage onto lower items.
PROOFING

1. Follow instructions above for holding. Note: water pan at base
of cabinet must be filled with clean warm water.

2. For proofing settings, rotate HEAT knob clockwise to 5 to 6
(approximately 90°F to 100°F; 32° to 38°C) and rotate HUMIDI­TY knob clockwise to 10 (90%+ RH).

3. Allow cabinet to preheat for approximately 25 minutes and load
food according to the instructions above.
