SERVICE ADJUSTMENTS
ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS
NOTICE
Contact the factory, the factory representative
or local service company to perform maintenance and repairs.
The steamer has been factory set so that when it is ON
and during the READY phase, it will maintain water temperature in the steam generator tank at approximately
205 degrees Fahrenheit (just below water boiling point).
However, for high altitude locations, an authorized servicer must adjust the steamer to achieve this temperature. To adjust:
1. Remove side panel and turn control panel power
switch to ON.
2. Open compartment door, and after about 15 minutes,
steam will be seen, entering the cooking compartment.
3. Turn thermostat shaft counterclockwise to lower temperature until steam just ceases to enter cooking
compartment and READY light goes on.
4. Replace side panel.
5. Follow TESTING PROCEDURES in this manual.
WATER FLOWS INTO DRAIN DURING SHUTDOWN
When steamer is shut down and cold water is running
continuously into the open drain, either or both solenoid
valves did not close when steamer was turned off.
1. Disassemble solenoid valve(s) and examine for scale
or foreign particles lodged in diaphragm or core tube.
2. Clean valve(s) thoroughly and reassemble, or replace
valve(s).
WATER OVERFLOWS INTO COOKING COMPARTMENT
When steamer is rst turned on for the day, and the following conditions occur: - READY light does not come on
after about 15 minutes,
• Water begins to overow into cooking compartment,
• Water ll solenoid valve is open, then any or all of
these symptoms may indicate a problem with the
operating probe due to either:
1. A short between the operating probe terminal and
body of the steamer. Call your authorized servicer.
2. Excessive scale build-up on the operating probe. This
acts as an “insulation” and prevents the probe from
sensing the water level. It is therefore unable to close
the water ll (solenoid) valve to shut off the water.
As a temporary solution, with power OFF, unscrew
probes, check visually, and clean or chip off scalant. Replace probe.
This problem is an indication of severe harmful water conditions which should be corrected immediately to avoid
damage to the components and ultimate malfunction of
the steamer.
HEATER ELEMENTS DO NOT COME ON
When the steamer is turned ON and heater elements do
not activate, and therefore, the READY light does not
come on, then the contactors may be burned out. If a considerable amount of “chattering” of contactors has been
previously experienced, then the thermostat bulb may be
coated with scalant and unable to sense water temperature in the boiler accurately, and therefore unable to control the contactors.
1. Replace contactors.
DRAIN WATER TEMPERATURE TOO LOW OR TOO
HIGH
Cooling solenoid valves are adjustable with ne adjustment screw on the bottom of the valve.
1. Run cooking compartment empty until drain temperature stabilizes.
2. Turn ne adjustment screw on cooling solenoid valve
out to decrease drain temperature and in to increase
drain temperature.

2. Unscrew operating thermostat bulb, clean off scalants and screw thermostat bulb back in.
This problem is an indication of inadequate water quality and is not covered under warranty. Have water quality
analysed and corrected immediately to avoid complete
malfunction of the steamer.
