required per the technical manual. Different models may have
different torque specifications. Contact Jackson Technical
Service if there are any questions regarding this.
AFTER MAINTENANCE ACTIONS
Once the new thermostat is installed, it will be nece-
sary to ensure that it operates at the required and appropriate
ranges. The new thermostat has an adjustment that can be
turned using a small flathead screwdriver. Several cycles will
need to be run on the unit while observing the final rinse tem-
perature. The thermostat needs to cycle so that the final rinse
water meets the indicated minimums on the machine data
plate for every cycle.
