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).
