CAUTION
The appliance and its parts are hot. Use care when operating, cleaning and servicing the appliance.
Once the steamer is installed and all mechanical connections have been made, thoroughly test the steamer before
operation.
1. Check that proper water, drain and electrical and gas connections have been made.
2. Turn main power switch ON.
3. Check that “Ignition” light comes on when the pilot burner is on.
4. After approximately 15 minutes, the “READY” light should come on, indicating that the water temperature is 205º
Fahrenheit (97º Celsius). When the “READY” light comes on, set timer to the “5 minute” position. With door open,
observe that no steam is entering the compartment and that the “COOKING” light is OFF.
5. Close compartment door. The COOKING light should now illuminate and steam should be heard entering the
compartment after about 45 seconds.
6. After five minutes of operation check drain line to ensure that water from the cold water condenser is flowing through
the drain line.
7. Open compartment door and observe that steam supply to chamber is cut off. “READY” light should again come on as
“COOKING” light turns “OFF”.
8. Close compartment door and let cooking cycle finish. When the timer returns to “0” position, a buzzer will sound
signaling the end of the cooking cycle. Buzzer must be manually turned off by setting the timer to its “OFF” position.
9. With all compartments of the steamer operating in the cooking cycle, check the temperature of the condensate
coming out the drain. If the drain temperature exceeds local plumbing code requirements, adjust the Thermostatic
Cooling Valve (TCV) out for a lower drain temperature and in for a higher drain temperature. A TCV setting of
approximately 2.75 yields a drain temperature of 140°F. A setting of approximately 2.5 or 3 yields temperatures of
125°F and 155°F, respectively.
