Carter-Hoffmann PH1490 - Manual (Page 4)

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 cabi-
net 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 door 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 and recon-
nect 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.
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 heat-
ing system at the same time. Tem-
peratures will get too high for prop-
er food holding.
DAILY OPERATION
CAUTION: SAFE
FOOD HOLDING
PRACTICES REC-
OMMENDED
Cooking food to a safe tempera-
ture, holding at a temperature of at
least 140°F is critical in the preven-
tion of foodborne illness. Hold only
cooked, hot food at 140°F or high-
er. This cabinet is not intended to
cook or reheat food. Food must be
at appropriate temperature before
being placed into cabinet.
CALIBRATIONS
If additional heat range is required in the heating unit, remove thermostat
knob, insert small straight blade screwdriver into opening and turn limit con-
trol 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.
THERMOSTAT CALIBRATION
THERMOMETER CALIBRATION
4
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.

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 quanti-
ty will result in temperatures that are
too high for proper holding.
