SERVICE PROCEDURES AND ADJUSTMENTS
WARNING:
CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR
MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL
TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER, ATTACH TEST
EQUIPMENT AND REAPPLY POWER TO TEST.
STEAM GENERATOR CLEANING
Follow the procedure as outlined in the "CLR
TREATMENT KIT" to remove the
Calcium/Lime/Rust build-up inside the tank, water
level probes, electric elements and drain system.
The CLR Kit contains, C.L.R. cleaner, funnel,
measuring cup, and " tubing.
In addition but not furnished in kit, rubber gloves
should be used.
DELIME BOARD OPERATION
AND ADJUSTMENT
The delime timer board tracks the cumulative
cooking hours and lights the delime light on the
control panel when the delime timer board reaches
a preset number of cooking hours. An LED on the
delime timer board lights indicating cook time hours
are accumulating.
After the delime timer board has accumulated the
preset number of cooking hours, the delime light will
light. It will stay lit until the power switch is moved to
the delime position or off. If the power switch is
turned “off” and then turned “on” without going to the
delime position, the delime light will relight.
1. To adjust the length of cooking hours before the
delime light will come on:
2. Access the delime timer board.
Position the switches in the “on” or “off” position to
obtain the desired hours. The number of switches
that are positioned “on” or “off” set the total hours. It
does not matter which individual switch is “on” or
“off”.

CONTROL THERMOSTAT
ADJUSTMENT
The procedure outlined below is to adjust the
thermostat temperature setting to a “ready” state
which is slightly below a continuous boil, (212°F) to
achieve the best “cooking” and steamer
performance.
When a cooking time is set on the timer, the delay
time for the steam generator to deliver a high quality
and volume of steam into the cooking compartment
will be minimal.
Correctly identifying the amount of steam coming
out of the ports is subjective. To help determine this,
does the steam coming out of the ports exhibit the
following:
1. Appear to be coming out under pressure.
2. Create a distinctive “whistling” sound during
steaming.
3. Produce a good “cloud” of steam in the cooking
compartment.
If the steaming meets the above criteria, the
thermostat is set correctly.
1. Remove the right side panel as outlined under
"COVERS AND PANELS.”
