component threads.
NOTE:
Some servicers, based upon their experience, recommend that probes and thermostats
be replaced whenever a frypot is replaced; however, this remains the customer’s decision.
21. Reverse steps 1-19 to reassemble fryer.
NOTE: Care should be taken not to over-torque nuts on frypots made of 400-series stainless

equivalent.
