3. Unplug the six terminals for the high heat elements
on the heater plate. Note which wires (in the harness)
go to which terminals. Both the terminals and wires
are numbered I to 6.
4. Unplug the set of two pigtail wires connecting the low
heat element to the heater plate.
5. Remove the two 6-32 self-tapping sheet metal
screws holding the thermostat switch to the steamer
table. Disconnect the two wires attached to the
thermostat switch by loosening the brass screws on
the switch. The switch must be removed to gain
access to these screws.
6. With a socket wrench with extension, remove the
four 1/2 inch nuts and lockwashers holding the heater
assembly in the steam generator.
7. The heater assembly may be removed by sliding it
out from the steam generator. Note that the high limit
thermostat is attached to the center (No. 2) heating
element.
8. Remove the gasket attached to the steam generator
and throw it away. Always use a new gasket.
To Prepare:
9. Remove the high limit thermostat from the heater
element by cutting the three stainless steel bands
with a diagonal cutter.
10. With an open ended wrench, loosen the capillary
fitting from the thermostat.
11. Apply high temperature pipe compound to the fitting
and install the high limit thermostat (or replacement)
fitting in the heater plate with an open ended wrench.
12. Fasten the thermostat bulb to the heater as
described in Section 10.12.
To Install:
13. Install new gasket onto the four threaded studs on
the steam generator.
14. Insert the entire assembly into the steam generator.
There is an orientation pin so that the assembly may
only be installed in the correct way. This pin is on the
left of the steam generator. When properly installed,
Terminals 1, 2 and 3 are on top.
15. Install the four lockwashers on each of the threaded
studs. Install the four 1/2 inch nuts by hand to retain
the assembly.
16. Using a socket wrench (with extension) tighten the
nuts to the threaded studs.
17. Attach the high limit thermostat box to the steamer
table using the two 6-32 screws.
18. Attach the six terminals of the wiring harness to the
heating elements. Note that the correct wire number
goes to the correct terminal. Plug in the low heat
pigtail wires to the harness.

1. Shut off electrical power to the steamer.
2. Remove the heating elements from the steam
generator as described in Section 10.11
3. With a diagonal cutter, cut the three stainless steel
bands holding the thermostat bulb to the heater
element.
4. With an open ended wrench, unscrew the thermostat
element from the heater plate.
To Install:
5. Apply high temperature pipe compound to the threads
of the new thermostat fitting. Screw the thermostat
fitting into the heater plate. Tighten with an open
ended wrench.
6. Position the bulb portion of the thermostat on top of
heater coil No. 2 (center heater).
7. Position the three stainless steel tie bands around
BOTH the heater coil and the thermostat bulb.
NOTICE:
Use only the stainless steel tie bands (Groen
P/N 100968). Be careful that the thermostat bulb is in
position before inserting the end of the band in the locking
pod, as once it is inserted it cannot be removed.
8. Once in position, pull the tie band all the way into the
locking pod. Using a needle-nose pliers hold the band
where it enters the pod and turn the band to draw it
tighter into the pod. Cut off the excess band with a
diagonal cutter.
