OWNER’S MANUAL

MODEL DH5F-333ARB – HEATED HOLDING CABINET

PRODUCT DESCRIPTION

The heated holding cabinet features Marshall’s own ThermoGlo™ heating technology. Heat radiates from every square inch of the upper and lower flat plate heating surfaces. This eliminates the need to clean intricate calrod, wire and reflector assemblies.

The cabinet can accommodate up to two 1/3 size pans

2 ½” deep per deck.

The cabinet features a time and temperature control as well as an on/off switch for each deck. This allows the user to run only the deck(s) of the cabinet needed to support the level of business during each part of the day or day of the week. Each pan has an associated three-digit display for the time and two LED indicator lights to the left and right of the time display. The LED will direct the operator which pans should be used first by displaying a green light while the back-up pan LED will display a red light.

PREHEAT:

1.The controller will stay in preheat mode ("PHt") for the entire preheat period (preheat time parameter) even though both heaters (top and bottom) have reached set points before the end of that period. If the controller is inadvertently turned OFF and back ON, the preheat period can be bypassed by a 3 second press of the down arrow button only if both heaters are within the allowed differential temperature set points (preheat bypass temperature parameter).

2.After preheat, the controller goes into idle mode "---". At this time, any timer can be started.

HOLDING TIME CYCLES:

1.To start a cycle, press a timer start/stop button. The display will show the holding time value in minutes and starts the countdown. The LED bars for that timer channel will then light steady green.

2.When the timer reaches the pre-alert value, the display will then alternate between showing the remaining time and "drP" for DROP, the LED bars will start flashing and a beeping will start. The user then has to acknowledge the pre-alert by a press of the timer start/stop button. The display will then flash the remaining time for the rest of the cycle, the LED bars will go back to steady and the beeping will stop.

3.When the timer reaches the "000" value, the display will flash "000", the LED bars will flash red and the beeping will start until the user acknowledges the end of the cycle by pressing the timer start/stop button. The timer will then go back to idle mode "---", the led bars will turn OFF and the beeping will stop.

4.Any holding cycle can be cancel at any time by a 3 second press of the timer start/stop button.

5.If at any time during normal operation, one heater’s temperature is falling or rising out of the allowed differential from set point (ready mode differential parameter), the displays will alternate between current mode and "LO" or "HI" to alert the user that the heater’s temperature is too low or too hi. This should remain until the heaters are back within the allowed differential.

CURRENT TEMPERATURES DISPLAY:

1.To view the heaters current temperature, press and hold the temperature button for 3 seconds. The display will then alternate between "toP" for top heater and its current temperature value.

2.To view the bottom heater current temperature, press the temperature button again. The display will then alternate between "bot" for bottom heater and its current temperature value.

3.A press of the temperature button will cycle between top and bottom current temperatures.

4.To exit temperature view mode and return to previous mode, press and hold the temperature button.
