UP/DOWN ARROW KEY
The up and down arrow keys are used for a variety of settings
when selecting the holding temperature. If an arrow key is pressed
and released the display will show the current set temperature for
two seconds. If an arrow key is held (at least eight seconds), the
value will change at a rapid rate. If the arrow key is pressed and
released in rapid succession, the set temperature will change by
increments of one degree.
ENABLE/DISABLE BEEPER
A beeper sounds when an error code is displayed. To choose
between beeper on and beeper off mode, the control must be
OFF, then press and hold the down arrow key until either "ON"
or "OFF" is shown in the LED display. Release arrow key when
desired mode is displayed.
FAHRENHEIT / CELSIUS
With the control OFF, to choose between Fahrenheit and Celsius,
press and hold the up arrow key until either °F or °C is shown in
the LED display. Release key when desired setting is displayed.
The control has a four-digit LED display. When the display
is ON, it will show current holding temperature, as well as
diagnostic information.
CONTROL LOCK
The warmer controls can be locked so that no changes can be
made to the set temperature.
To lock the display, press and hold the ON/OFF key and the Up
Arrow key at the same time. The lock indicator will illuminate.
When the lock indicator is illuminated, additional programming
will not be functional other than the key sequence required to
unlock the panel.
To unlock the display, press and hold the ON/OFF key and the
Down Arrow key at the same time. The lock indicator will
extinguish. The panel keys will resume normal function.
1. Preheat at 200°F (93°C) for
30 minutes.
Press the ON key, and set the temperature to
200°F (93C°) by using the UP/DOWN arrow
keys. Allow a minimum of 30 minutes
preheating time before loading the drawer
warmer with food. The LED heat indicator
light will go “OUT” after approximately 30
minutes preheat time, or when the air
temperature inside the unit reaches the
temperature set by the operator.
2. Load with pans of hot food only.
The purpose of the warmer is to maintain
hot food at proper serving temperature.
Only hot food should be placed into the
unit. Before loading with food, use a food
thermometer to make certain all products
are at an internal temperature range of 140°
to 160°F (60° to 71°C). Any food product
not within the proper temperature range
should be heated before loading into the
unit.
3. Reset the control to 160°F (71°C).
Check to make certain the drawer is
securely closed, and reset to 160°F (71°C) by
using the UP/DOWN keys.
THIS WILL NOT NECESSARILY BE THE
FINAL SETTING.
The proper temperature range will depend
on the type and quantity of product. When
holding food for prolonged periods, it is
advisable to periodically check the internal
temperature of each item with a food
thermometer to assure maintenance of the
proper temperature range of 140° to 160°F
(60° to 71°C).
