run through an automatic washer.

2. To clean stainless steel surfaces use only cleansers, detergents, de­greasers, or sanitizers that are certified to be "chloride-free" and
"phosphate-free," and cleansers, degreasers, or sanitizers only in the
recommended concentrations. DO NOT exceed recommended con­centrations or mixing ratios. After cleaning and sanitizing, rinse all
exposed surfaces thoroughly with large amounts of clean, clear water.
Wipe off any standing liquid or residue from all surfaces, corners and
rear edges.

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.

CAUTION: SAFE
FOOD HOLDING
PRACTICES REC­OMMENDED

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

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.

DAILY OPERATION

1. Plug the heater into a proven power source. The white indicator lamp
and the fan will operate continuously whenever the heater is plugged
in.

2. 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.

3. 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.

4. During loading, the cabinet temperature will drop. Close the do or and
wait 10-15 minutes for the cabinet to recover air temperature before
disconnecting from the power source.

5. 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.

6. Upon reaching the service area, unwind the power cord a nd 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.

7. 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

Thermometer dial

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.

THERMOSTAT CALIBRATION

THERMOMETER CALIBRATION

CALIBRATIONS

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 recomme nded 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 W D-40, silic one spra y, grap hi te or other com mercial
lubricants for stainless steel products. Do not use oil.

PERIMETER BUMPERS

Vinyl which has been dislodged from the channel due t o severe bumping or scraping can be pried back into
place with a common screwdriver.
