Initial Start-Up
After the Combo SuperSystem has been installed, perform initial testing to ensure that the unit is operating
correctly.
1. Remove all literature and packing materials from the interior and exterior of the unit.
2. Make sure both cold water supply lines are open and none of the fittings is leaking.
3. Turn on electrical service to the unit.
4. High altitude operation. The altitude of operation can be programmed into the Convection Combo. At
altitudes above 2,000 feet, the unit will not operate in Steamer or Combo Mode unless the altitude is
set. To set the altitude:
a. If the unit is on, turn it off by pressing the ON touch pad.
b. Press and hold the STEAM touch pad while turning the unit on by pressing the ON touch pad. The
timer display will show the letters AL and a number that represents the altitude in thousands of feet. If
the altitude has never been set on your unit, the number displayed will be 1.
c. Enter the proper altitude value, between 1 and 15, using the numbered touch pads. For example, if
the unit will be used at an altitude of 7,000 feet, press the 7 touch pad.
d. Press the START touch pad.
5. To test Steamer Mode operation, turn on the unit. (For details of operating procedure, see the
Operation section of this manual.) Clear any time from the time display, close the door, and press the
STEAM touch pad. (If the HOT light is on, see the Fast Cool instructions in the Operation section.) The
WAIT light will stay on while the steam generator fills with water and heats the water. Within 15 minutes
the WAIT light should go off and the READY light should come on, indicating that the water has reached
the standby temperature. The timer controls operation (in Steamer Mode only), so enter a time, then
push START. The colon on the time display will blink, and the generator will begin to produce steam.
The timer will not count down, if the READY light is not lit.
WARNING: STEAM CAN CAUSE BURNS. AVOID ESCAPING STEAM WHEN OENING
DOOR.
IMPORTANT: You cannot change modes if the timer is running.
6. To test Combo Mode operation, turn the power on and clear any time from the timer display, Press
the COMBO touch pad. Set the COOK temperature to 300 F (150°C). The WAIT light will come on and
stay on, while (1) the steam generator fills with water and heats the water to standby temperature and
(2) the air heater raises air temperature to 300°F. Both actions should be completed in about 15
minutes, starting with a cold unit. Then the WAIT light will go off and the READY light will come on.
WARNING: STEAM CAN CAUSE BURNS. AVOID ESCAPING STEAM WHEN OENING
DOOR.
IMPORTANT: The timer does not control the oven in Combo Mode or Oven Mode.
7. To test Oven Mode operation, turn the power on and clear any time from the timer display. Press the
OVEN touch pad. Set the COOK temperature to 350°F (175°C). The WAIT light will come on. Within 10
minutes from a cold start, the WAIT light should go off and the READY light should come on. When that
happens, turn the COOK temperature setting down to 300°F (150°C). The HOT light will come on.
8. To test Meat Probe operation, turn the PROBE knob clockwise to activate the probe. Confirm that the
temperature shown in the TIME display is the actual temperature of the probe. Then turn the PROBE
knob counterclockwise to inactivate the probe.
9. To shut down the unit, first clear the timer. Then press the mode touch pad for the mode the unit is in.
Switch off the power.
10. If the Convection Combo behaves as described, the unit is functioning correctly and ready for use.
