The instructions provided here are for maintenance per- sonnel only. Unauthorized persons should not attempt any of the steps contained in these instructions.

Warning: many of the instructions and steps within this document require the use of tools. Only authorized per- sonnel should ever perform any maintenance procedure on the dishmachine!

PREPARATION

1.Power must be secured to the unit at the service break- er. Tag or lock out the service breaker to prevent accidental or unauthorized energizing of the machine.

2.Ensure that incoming water to the machine is secured either by use of a shut-off valve or disconnecting the incoming water line.

3.The unit must be drained completely with the drain stopper removed (if applicable).

4.Remove any and all access covers.

TOOLS REQUIRED

The following tools may be needed to perform this main- tenance evolution:

1.3/8” Nutdriver

2.7/16” Combination Wrench

3.Needlenose Pliers

4.Phillipshead Screwdriver

5.Flathead Screwdriver

6.Ratchet with 1/2” Socket

TIME REQUIRED

It is estimated that it will take (1) person thirty minutes to perform this task, not including all of the items indicated in the sec- tion entitled “PREPARATION”.

IMPORTANT NOTES

1.Read these instructions thoroughly before attempting this maintenance task. Become familiar with the parts and what actions need to be taken. This will save time in the long run!

STEPS

1.Some machines require that the thermostat bracket be removed from the heater. Using a ratchet, extension and 1/2” socket, remove the nuts and lock washer holding the bracket on. Otherwise, remove the thermostat bracket with the 3/8” nutdriver.

2.With the thermostat and thermostat bracket safely out of the way, use a 7/16” combination wrench to loosen and then remove the imperial brass fitting holding the probe in.

3.Remove the wires from the old thermostat. It may be necessary to use the needlenose pliers to accomplish this.

4.Remove the thermostat bracket mounting nuts with the 7/16” nutdriver.

5.Attach the jumper wires to the wires that you removed from the old thermostat, ensuring to match the wire colors up correctly.

6.Slide the new imperial brass fitting from your kit onto the new thermostat.

7.Insert the new thermostat/brass fitting combination into the well and tighten down the brass fitting by hand.

8.Use the 7/16” combination wrench to tighten down the brass fit- ting, while also positioning the new thermostat so that it does not hang over the heater.

9.Note: regardless of the unit this is being done to, the concept is to ensure that the thermostat cannot come into contact with the heater leads or interfere with the placement of any covers.

10.Use the phillipshead screwdriver to remove the attachment screws on the thermostat for the NORMALLY CLOSED and COM- MON points.

11.Attach the ring ends of the jumpers to the cups/screws removed from the thermostat. Refer to your machine schematic if you have any questions regarding this.

12.Once both wires are attached, ensure that there is no excess hanging out where it could become pinched by any cover or such.

13.Replace the heater nuts (if removed) and torque down as required per the technical manual. Different models may have dif- ferent torque specifications. Contact Jackson Technical Service if there are any questions regarding this.
