CHAPTER 4 OPERATING TESTS This procedure evaluates the function of the major operating controls of a SteamChef.
• The SteamChef may be equipped with a Keypad Control Panel, Dial Timer Control Panel, or an
ON/OFF Control Panel.
• The ON/OFF control model works like the manual operation of the Timer models EXCEPT that a
selector switch is used to turn the cooking function from standby heat (OFF) to the Cooking Mode (ON).
A. Startup Procedure
1. Set the ON/OFF Lever to the OFF position and open the SteamChef door. There should be
no water in the SteamChef.
2. Wait for the cooking compartment to cool from the Burner Ignition Test.
3. See Figure 3-9. Remove the slide racks and the KleanShield™ and check that neither the
KleanShield™ nor the reservoir drains are blocked. Replace the KleanShield™ and pan racks
and check for proper installation of the KleanShield™, fan guard, air diverter, slide racks, and
door gasket assembly.
4. Be sure the Main External Power Switch is in the OFF position. See Figure 3-7.
5. Verify installation of the proper size fuses or breakers. See the Rating Plate for electrical data.
6. The front burner box cover is shipped loose. Wait until testing is done before installing it.
7. Remove the control side panel.
8. Check the internal wiring and make sure there are no loose or disconnected wires.
9. Verify that the supply wiring is of adequate size and that the SteamChef is properly grounded.
10. Correct any deficiencies.
B. Drain Rinse Inspection (Continued from Item 1, Startup Procedure)
1. Turn the ON/OFF lever to the OFF position.
2. Turn ON the gas supply to the SteamChef (if not already on).
3. Turn ON the water supply to the SteamChef (if not already on).
4. Turn ON the electric power to the SteamChef at the Main External Power Switch.
a. The SteamChef immediately starts a 3-minute drain rinse cycle.
b. During the drain rinse cycle, the fill and drain valves are all the way open while the steam
drain lines are flushed with fresh water.
5. Stop the drain rinse cycle before it is complete by setting the ON/OFF lever the ON position.
This energizes the operating control circuits, stops the drain rinse cycle, and the fills the
reservoir with water.
6. Restart the drain rinse cycle by setting the ON/OFF lever to the OFF position. During the
automatic drain rinse cycle, make the following checks.
a. The ON/OFF lever must be turned all the way to OFF to START the drain rinse cycle.
b. Look at the gap between the SteamChef drain and the floor drain. A steady stream of
water flows from the SteamChef drain. If no water flows, make sure the water supply is
turned on.
c. Check for plumbing leaks.
d. After about 3 minutes, the cycle is complete. Check the gap at the floor drain. No more
water flows from the drain.
