GROUNDING INSTRUCTIONS

This appliance is equipped with a cord having a grounding wire with a grounding plug which must be plugged into an
outlet that is properly installed and grounded. In the event of an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric current.

WARNING—Improper use of the grounding can result in a risk of electric shock. Consult a qualified electrician or
service agent if the grounding instructions are not completely understood, or if doubt exists as to whether the applianc e
is properly grounded.

NORMAL OPERATION

1. Turn POWER SWITCH, located at the top front panel, to ON. Pre-heat
cabinet for 90 minutes. When first turned on, digital readout will boot up
and display the software codes and then “LO” until the cabinet reaches
122°F (50°C). After the cabinet reaches 122°F (50°C), the digital
readout will display the current temperature, until the temperature
reaches the setpoint. Once the cabinet reaches setpoint, the digital
readout will display the current menu item for each pan (i.e. “MST1”).
This indicates the cabinet is ready to hold product.

You may change the menu item by pressing the UP and
DOWN ARROW KEYS. Each controller has five pre-set programs
(MST1, MST2, CSP1, CSP2, OFF) for each pan position. In the OFF
position, temperature setpoint and time cannot be modified.

2. Load cooked product into pans and place pans on shelves. For moist

food holding MST1 and MST2, use with pan covers in place; bottom
heat will be ON and top heat will be OFF. For crispy food holding CSP1
and CSP2, remove pan covers; top and bottom heat will be ON.
