INSTALLATION and START-UP

WARNING:

Risk of personal injury

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

IMPORTANT:

Each power cord is 6' long

If necessary, contact a licensed
electrician to install an appropriate
15 amp electrical circuit with correct
NEMA receptacle for each heater.

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

LOCATION

Read equipment manual completely before installing and op­erating the cabinet.

Unit must be installed by qualified service personnel on­ly. Unit must be installed in such a fashion to bear the weight

of the cabinet when fully loaded; minimum 350 pounds.
The power connection for each heater is a grounded plug.

Electrical information for each heater is provided on the heat-
er serial tag on the front of each heater. Verify that the proper
electrical service required for this cabinet is available prior to
installation. Plug the power cords into grounded outlets with a
electrical service according to the electrical information pro­vided on page 3.

Heater serial tag locations

Cabinet serial tag (Note
serial number if calling
for service)

GROUNDING INSTRUCTIONS

This appliance is equipped with cords 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 (page 8).

2. Plug the power cord of the cabinet into grounded outlets
with a electrical service according to the electrical infor­mation provided on page 3. Set POWER switches to the
“ON” position.

3. 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.

DAILY CLEANING PROCEDURES

CAUTION:
ELECTRIC SHOCK
HAZARD

Disconnect appliance from
electric power before cleaning.

CAUTION:
HOT SURFACE

Exposed surfaces can

be hot to the touch
and may cause burns. Allow
appliance to cool before clean­ing.

IMPORTANT:

DO NOT spill or pour

water into controls,
control panel or wiring. Water
damage is not covered by the
warranty.

CAUTION:

Beware of sharp edg­es with sheet metal

during cleaning process.

CAUTION:

Do not use steel wool

pads to clean cabinet.
Ferrous deposits will cause
rusting; roughness of the pad
will scratch the black powder
coating on the front door frame.

1. After all food products have been removed from the cabinet,
turn the power switches to “OFF” and allow the cabinet to
cool. If cabinet is supplied with a plug, disconnect from pow­er prior to cleaning.

2. Remove the pan rack assemblies and clean according to
manufacturer’s directions.

3. Remove the doors from the large cabinet by flipping up and
lifting off. To remove the doors from the smaller cabinet, first
remove the front door by lifting the door up and out of the
track. Then remove metal track divider that is located be­tween the doors. Lastly, lift the rear door up and out of the
track. Doors should be washed with a clean damp cloth and
chlorine-free detergent. Rinse thoroughly with clean damp
cloth and allow to dry. Do not use abrasive cleaners, waxes,
car polish, or substances containing strong aromatic sol­vents or alcohol. Do not use scratch pads or steel wool on
the plastic doors. Do not use stainless steel cleaner.

4. Remove bottom heat duct and then remove the rear heat
duct in each cabinet. Using a clean damp cloth with appro­priate cleaner (see page 9), clean the inside of the unit and
the removed parts. Wipe any residue with clean damp cloth.
Reinstall all parts when they are dry and clean.

5. 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.

6. Plastic control panel should be washed with a clean damp
cloth and chlorine-free detergent. Rinse thoroughly with
clean damp cloth and allow to dry. Do not use abrasive
cleaners, waxes, car polish, or substances containing strong
aromatic solvents or alcohol. Do not use stainless steel
cleaner.

TIPS FOR CLEANING STAINLESS STEEL

RECOMMENDED TIPS FOR CLEANING STAINLESS STEEL

Purpose Frequency Cleaning Agent Method of Application

Routine Daily Soap, ammonia Sponge with cloth, rinse with clear water
cleaning detergent and water and wipe dry.

Smears/ As Stainless steel cleaner Rub with soft cloth as directed on package.
Fingerprints needed or similar products Rub in direction of grain of stainless steel.
Do not use on vinyl trim.

Stubborn Daily Any chloride-free Apply with damp sponge or cloth. Rub in
spots and as or direction of grain of stainless steel. Rinse
stains needed phosphate-free thoroughly, especially if cleaner contains
cleaner chlorine bleach, do not use on vinyl trim.

Hard water Daily Vinegar Swab with cloth.
spots as needed Rinse with water and wipe 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.

2. Check cooling fan—replace if necessary. NOTE: The fan is con-

trolled by Hi Limit of 120°F and starts when the temperature in
the wire box is higher than 120°F. This can take up to 6 minutes.

Also, the fan might run after turning the switch OFF, until the tem-

perature falls under 120°F.

1. Remove cover, press Hi Limit reset button on “FAN SAFETY” limit
(Part Number: 18600-0117)

2. Check operation of heater blower; replace if necessary. NOTE:
