Step 4
Put the cartridge heaters and RTD through the slot in the
gasket. Align the handle with the body so that the
thermometer holes in the body, gasket and handle line up.
Slide the heater cartridges into the outer holes and the RTD
into the drilled hole in the body. Make sure the cartridges
are all the way in, at least flush with the bottom of the body
recess.

Step 5
Clean area around the screw hole to ensure good electrical
connection.
Attach the ground wire to the heater body with the #6-32
screw.
Step 6
Put the handle on the top of the body while pushing the RTD
as deep as it will go down in its hole. The wires to the
cartridge heaters will fold into the recess. Loosely bolt on
the new handle/controller assy with the thermometer guard
and stripper bar using the (2) 1/4-20 socket head
capscrews. If available, apply high temperature anti-seize
compound (not included in the kit) to the screw threads.
Install the thermometer and then tighten the two socket
head capscrews using a 3/16” hex wrench.

Step 7
Several Part Number Labels may be included in the kit.
Choose the one that matches the heater size, voltage and
configuration. Affix it to the back of the handle. Be sure it is
turned the same way as the MMI logo on the handle.
Discard the remaining Part Number labels.
