Before Initial Use:
Clean appliance with a clean, damp cloth and
mild soap solution. Glass cleaner or distilled
vinegar can be used on any glass. Clean and
install the pans, shelves and side racks.
1. Preheat at 200°F (93°C) for 30 minutes.
Press the ON key, and set the temperature to
200°F (93°) by using the UP/DOWN arrow keys.
Allow a minimum of 30 minutes preheating
time before loading the holding cabinet with
food. Closing the vents on the inside of the
door will speed the preheating process. 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. The Set
indicator will light up anytime the temperature is
set or reset.
2. Load with hot food only.
The purpose of the holding cabinet is to maintain
hot food at proper serving temperature. Only
hot food should be placed into the cabinet.
Before loading the cabinet 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 holding cabinet.
3. Reset the control to 160°F (71°C).
Check to make certain the cabinet door 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--or closing or opening
the door vents--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).
