b. Drain Rinse Inspection (continue from Startup Procedure)
(7) Turn ON the water supply to the steamer.
(8) Turn ON electric power to the steamer at the main external power switch. The steamer will
immediately start a 3-minute drain rinse cycle. During the drain rinse cycle, the fill and drain
valves are fully open while the steam generator drains are flushed with fresh water.
(9) Stop the drain rinse cycle before it is complete by setting the ON/OFF lever/switch to the ON
position. This energizes the operating control circuits, the green Power ON and amber
“SureCook” (Timer Models only) indicators on the control panel light, drain rinse stops, and
the steam reservoir begins to fill with water.
(10)Restart the drain rinse cycle by setting the ON/OFF switches to the OFF position. During the
automatic drain rinse cycle, make the following checks.
xCheck for plumbing leaks.
xLook at the one-inch vent gap between the steamer drainpipe and the floor drain. A steady
stream of water should be draining from the steamer.
xNOTE: The ON/OFF lever must be turned fully to the OFF position to START the proper
drain rinse sequence.
xAfter about 3 minutes, the cycle is complete. Check the gap at the steam drain; there
should be no more water flow at this point.
c. Operating Tests and Final Checkout Procedure (Continue from drain rinse Inspection)
(Sequence of Operation)
(11)At the start of this test the controls should be set as follows:
xThe main power switch is ON.
xThe ON/OFF lever/switch is OFF (The green and amber [timer models only] indicators on
the control panels are not lit).
xThe TIMED/MANUAL switch is in the TIMED position. (or for ON/OFF models the ON/OFF
compartment selector switch is in the OFF position)
(12)Set the compartment timer to zero, by turning the dial counter clockwise until it points to the 0
mark.
(13) Set the ON/OFF lever/switch to the ON position. As the steam reservoir fills with water, check
the following functions.
a). The green Power ON and amber “SureCook” indicator lights turn ON. The fill valve opens
and water begins to fill the compartment reservoir.
b). Immediately, water should begin appearing in the bottom of the compartment reservoir.
Close the compartment door to close the door interlock circuit. As the water level in the
compartment reservoir rises;
iCheck that no water flows from the drain opening.
iCheck for plumbing leaks in the control compartment.
WARNING
When checking inside the steamer always open the door slowly
and stand to the side and back away from the steamer. Water
leaking from the door gasket can be a sign of a blocked drain. If
the drain is blocked, hot water can accumulate inside the
compartment and spill out when the door is opened.
