UNPACKING AND INSTALLATION
CAUTION: Electric Shock Hazard
All servicing requiring access to non-insulated components must be performed by qualified service
personnel. Do not open any access panels which require the use of tools. Failure to heed this warning can result in electrical shock. Disconnect this appliance from electrical power before performing
any maintenance or servicing.
WARNING: Injury Hazard
All installation procedures must be performed by qualified personnel with full knowledge of all applicable electrical codes. Failure could result in property damage and personal injury.
WARNING Electric Shock Hazard
Appliance must be plugged into a properly grounded receptacle to prevent possible shock hazard.
Electrical shock will cause death or serious Injury.
CAUTION: Burn Hazard
Interior surfaces of the appliance may be HOT to the touch, and can cause serious burns.
WARNING:
Risk of personal injury
Installation procedures must
be performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure can result in
personal injury and property damage.
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:
Power cord is 10' long.
If necessary, contact a licensed electrician to install
an appropriate 15 amp electrical circuit with NEMA 5-15R receptacle. DO
NOT use an extension cord.
IMPORTANT:
Damage to unit due to being
connected to the wrong voltage or phase is NOT covered by warranty.
Unpack the cart and heating unit. Ensure that all packing materials
and protective plastic has been removed from the unit. Inspect all
components for completeness and condition.
NOTE: DO NOT discard the carton or other packing materials until
you have inspected the appliance for hidden damage and tested it
for proper operation. Refer to SHIPPING DAMAGE CLAIM PROCEDURE on PAGE 7 of this manual.
Appliance should be thoroughly cleaned before use. See CLEANING
INSTRUCTIONS, page 3.
Plug the heating unit into a properly grounded NEMA 5-15R electrical receptacle. DO NOT MODIFY CORD
PLUG.
For first time operation of the cabinet, 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.
Before using, familiarize yourself with the
heater controls. Read entire manual before
operating this cart.
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 electrical 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.

DAMAGE
Do not tip cart onto the
doors to drain excess
water. Permanent damage to the
doors and hinges will result. Use a
clean dry cloth to mop any excess
water inside cabinet after cleaning.
3. Vinyl trim should be washed with a chlorine-free detergent and water.
Rinse thoroughly with clear water and allow to dry. Never use abrasive cleaners, waxes, car polish, or substances containing strong aromatic solvents or alcohol. Use of direct steam / hot water cleaning
at temperatures above 190°F may result in “bubbling” or loosening of
vinyl adhesive.
4. After all parts are dry, reinstall them and then replace the heating unit.
IMPORTANT: Cleansers, detergents, degreasers, sanitizers or bleaching agents that contain chlorides or
phosphates will cause permanent damage to stainless steel products. This damage appears as pits,
eruptions, voids, small holes, cracks, severe discolorations or dulling of the metal finish. Water with a high
chlorine 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 WARRANTY.

FOOD HOLDING
PRACTICES RECOMMENDED
2.
Cooking food to a safe temperature, holding at a temperature of at
least 140°F is critical in the prevention of foodborne illness. Hold only
cooked, hot food at 140°F or higher. This cabinet is not intended to
cook or reheat food. Food must be
at appropriate temperature before
being placed into cabinet.

WARNING:
FOR EQUAHEAT
BANQUET CARTS
6.
EquaHeat Banquet
carts are equipped with canned fuel
drawers at the base of the door(s).
If you are using canned fuel (i.e.
Sterno™), do not operate the heating system at the same time. Temperatures will get too high for proper food holding.
7.
Plug the heater into a proven power source. The white indicator lamp
and the fan will operate continuously whenever the heater is plugged
in.
Turn the thermostat to number 4 or 5 on the knob. Be sure the cabinet door(s) are fully closed during the pre-heat time.
Food serving temperature will vary with the mass, type and quantity
of food being held. Set the thermostat for the desired holding setting.
Turn clockwise to increase the temperature and counter-clockwise to
decrease the temperature.
During loading, the cabinet temperature will drop. Close the door and
wait 10-15 minutes for the cabinet to recover air temperature before
disconnecting from the power source.
Be sure to remove the plug from the outlet and wind the cord on the
cord bracket or push handle before moving the cart. Move the cart to
the service area as quickly as possible.
Upon reaching the service area, unwind the power cord and reconnect the heater as quickly as possible. Wait 10-15 minutes (check the
thermometer to see if the temperature is are the desired level). If not
adjust the thermostat as required.
When removing product from the cart, start at the bottom and work to
the top position. This keeps food hotter and eliminates spillage on to
lower items.
NOTE: BB series EquaHeat Banquet
carts have drawers for canned fuel at
the base of the cabinet. Cut-outs
indicate where canned fuel should be
inserted into the drawers. Do not
operate the electric heating system
at the same time you are using
canned fuel or exceed the capacity
of canned fuel (2 per door). Using
more than the recommended quantity will result in temperatures that are
too high for proper holding.

CALIBRATIONS
THERMOSTAT CALIBRATION
THERMOMETER CALIBRATION
If additional heat range is required in the heating unit, remove thermostat
knob, insert small straight blade screwdriver into opening and turn limit control set screw counter-clockwise one full turn. Replace thermostat knob and
turn clockwise to reach new maximum temperature. Repeat this until desired
temperature is reached. Each 1/4 turn of the calibration set screw will raise
the element heating capacity by approximately 25°F to 35°F (4°C to 7°C).
If a reduction of heat is desired, turn limit control set screw clockwise one full
turn. Hold the door open and allow the unit to cool until inside temperature is
below the temperature desired. Close the door and allow unit to rise to new
maximum temperature. Repeat until desired temperature is reached.
Place an oven thermometer in the center of the cabinet. Turn heater on; turn
thermostat to maximum setting and wait approximately 45 minutes. Open the
door and check inside thermometer temperature. If recalibration is required,
pry the plastic cover off the dial body and with a small flat blade screwdriver,
insert into the pointer as shown. Carefully turn the pointer with your finger to
the correct setting. Be careful not to bend the pointer. It is very fragile.

GENERAL MAINTENANCE INSTRUCTIONS
CASTERS
Some casters are equipped with Zerk grease fittings so that they may be easily lubricated with a grease gun.
Recommended lubrication is at least once every six months. Lubrication will be required more frequently if carts
are cleaned with a hot water or steam cleaning system. Casters with special bearings are recommended for frequent cart wash or steam cleaning situations.
LATCHES
Check frequently to insure that all door latches are secure. Latches may become “sticky” due to residue build-up
from daily use and cleaning. Lubricate latches regularly with WD-40, silicone spray, graphite or other commercial
lubricants for stainless steel products. Do not use oil.
PERIMETER BUMPERS
Vinyl which has been dislodged from the channel due to severe bumping or scraping can be pried back into
place with a common screwdriver.
