INSTALLATION (cont’d.)

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 10' long

If necessary, contact a licensed
electrician to install an appropriate
electrical circuit with correct NEMA
receptacle. See chart on this page.

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

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.

To prevent an electrical shock hazard between the
appliance and other appliances or metal parts in close
vicinity, an equalization-bonding stud is provided. An
equalization bonding lead must be connected to this
stud and the other appliances/metal parts to provide
sufficient protection against potential difference. The
terminal is marked with the following symbol:

START-UP

1. Prior to use, thoro ughly clean the interior of the unit, ac­cording to the instructions in this manual.

2. Plug the power cord of the cabinet into a grounded outlet
with a electrical service according to the electrical infor­mation provided below. Maintain 2” clearance on each
side of the cabinet.

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.

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 and
counter from being submerged in
water. Do not operate if unit has
been in contact with water.

READY

Half-size cabinets with four or five shelves will have one con­troller for all shelves. Full size cabinets will have two control­lers, one for the top 4 or 5 shelves and one for the bottom 4 or 5
shelves (depending on model number).

1. Press the POWER SWITCH, located at the top front panel, to
ON. Illuminated portion of switch will glow, indicating power is
ON. Pre-heat cabinet for 20 minutes. When first turned on, digi­tal readout will display “LO” until the cabinet reaches 122°F. Af­ter the cabinet reaches 122°F, the digital readout will display the
current temperature, until the temperature reaches the setpoint.
Once the cabinet reaches setpoint, the digital readout will dis­play “P 1”. This indicates the cabinet is ready to hold product.

NOTE: Press and release the appropriate TEMP KEY
to view or verify setpoint. Setpoint will display briefly. If
temperature setpoint needs to be changed, refer to
Programming Instructions, page 9.

NOTE: Timer cannot be started until the cabinet is preheated.

Select the desired timer program by pressing the UP / DOWN
ARROW KEYS. Each controller has six programmable timers
(“P 1”, “P 2”, “P 3”, “P 4”, “P 5” and “P 6”) for each group of cavi­ties. NOTE: controller 1 controls all shelves on 1/2 size (four and
five-shelf) units and top 4 (on eight-shelf units) or top 5 (on 10­shelf units) on full-size units with eight or ten shelves; controller
2, on full size eight or ten shelf units only, controls the bottom 4
(on eight-shelf units) or bottom 5 (on 10-shelf units).

2. Different program times can be used for different parts of the
day (breakfast, lunch, dinner) or for alternate products.

NOTE: Program timer defaults to “P 1” each time the cabinet is
turned OFF and ten back ON.

NOTE: To select other timer programs (“P 2” - “P 6”),

press the INCREASE KEY or DECREASE KEY
until the digital readout displays the desired program.

3. After pre-heat, the digital readout will display the current select­ed timer (e.g. “P 1”), indicating that the cabinet is ready to hold
product.

4. Load cooked product into pans and place pans on shelves.

5. Press TIME key to start the timer. Refer to Programming

Instructions (page 9) to change programmed time.

CAUTION:

Beware of sharp edg­es with sheet metal

during cleaning process.

1. After all food products have been removed from the cabinet,
turn the power switch to “OFF” and allow the cabinet to cool.

2. Unplug the unit prior to any cleaning.

3. If applicable, remove product covers from each shelf.

4. Hand wash covers and cabinet with chloride/phosphate-free
soap or detergent. Clean the inside of the unit as wells as the
removed parts. DO NOT exceed recommended concentra­tions or mixing ratios. Do not use abrasive cleaners, waxes,
car polish, or substances containing strong aromatic solvents
or alcohol.

5. Rinse covers and wipe cabinet interior with clean damp cloth.
Wipe off any standing liquid or residue from all surfaces, cor­ners, or near edges and allow to dry.

6. Inspect and clean the areas where there are vents or filters,
making sure no water gets into the internal controls or electri­cal areas of the cabinet.

7. Reinstall product covers when they are thoroughly dry.

CAUTION:

Cleansers, detergents, degreasers, sanitizers, or bleaching

agents that contain chlorides or phosphates will cause per­manent damage to stainless steel products. The damage appears as
pits, eruptions, voids, small holes, severe discoloration or dulling of
the metal finish.

Water with high chloride content can also damage stainless steel.
If unsure of your water quality, we recommend you have it tested.
THIS DAMAGE IS PERMANENT, COSTLY TO REPAIR, AND IS
NOT COVERED BY THE WARRANTY.

CABINET MAINTENANCE

WARNING:

DO NOT perform

these procedures
while the cabinet is turned on
or heated. Turn off the power
and wait for the cabinet to cool
to room temperature.

CASTERS

Caster bearings may be equipped with Zerk grease fittings so that
they may be easily lubricated with a grease gun. Lubricate bear­ings at least once every six months.

STACKING FOUR– AND FIVE-SHELF UNITS

This task takes about 30 minutes & requires two people.

1. Using a screwdriver, remove the screws that attach the top on
the unit that you wish to be on the bottom of the stack (unit
#1). Remove the cover and set aside.

2. Place a large piece of cardboard, moving blanket or other pro­tective material on the floor. For the other unit (unit #2), care­fully tip it onto one of its sides (not the front or the rear). Then,
using a wrench, remove the bolts that attach the casters to the
bottom of the unit #2. Set casters aside.

3. Tip unit #2 back to an upright position. Lift and place unit #2 so
it nests in the open top of unit #1, taking care to line up the
holes where the screws were removed.

4. Replace screws into the top edge of unit #1, securing it to the
bottom of unit #2.

5. Keep extra top and casters on hand for spare parts, or if you
should ever wish to separate the units.
