Rack Conveyor Dishmachine
Maintenance Instructions
Jackson rack conveyor machines come equipped with
heaters to ensure proper ware washing results. Occasionally,
some of these components may need replacing to maintain opti-
mum performance.
Jackson offers all of the repair parts necessary for per-
forming this task.
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.
TOOLS REQUIRED
The following tools will be needed to perform this mainte-
nance evolution:
1. 3/8” Nutdriver
2. Ratchet
3. 1/2” Socket
4. 3/8” Socket
5. Phillipshead Screwdriver
6. Needlenose Pliers
7. Torque Wrench
8. Siliconee Sealant
9. Amp Meter
TIME REQUIRED
It is estimated that it will take (1) person ninety 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. Remove the front dress panel.
2. Remove the heater box cover to expose the heater. Set the
cover and hardware to the side.
3. Remove the incoming electrical lines from the heater. Set the
hardware to the side.
4. Push the incoming electrical lines out of the way.
5. The thermostat probe needs to be removed from the well inside
the heater. The probe is secured in place with silicone that must be
peeled away prior to attempting to remove it. It is important that
you do not damage the probe during this part of the maintenance
action. If you do, then the thermostat will have to be replaced as
well.
6. Using your hand or needlenose pliers, remove the silicone so
that the thermostat probe may be gently removed.

Removing the power lines.
Heater without power lines attached.
7. With the thermostat probe out of the way, use the 1/2” socket
and ratchet to remove the nuts holding the heater to the tub.
Remove all nuts and lockwashers.
8. Remove the heater from the tub weldment.
9. Remove the gasket.
10. Before proceeding any further, it is important to verify that the
tub wall is free of any excess debris so that when the new gasket
is applied, there are no gaps that could lead to leaking around the
heater.
11. Apply the new heater gasket from your service kit.
12. Slide the heater onto the studs and apply by hand the lock
-
washers and nuts. Tighten the nuts by hand and then use the
torque wrench set to 154 in-lbs to ensure that the nuts are secure.
13. The thermostat probe needs to be placed into the well of the
new heater. Again, use caution when doing this so that the probe
or the capillary tube do not become broken. If this occurs, then the
thermostat will have to be replaced.

14. Apply silicone to seal the well and hold the thermostat probe in
place.
15. Reattach the incoming power lines to the heater, ensuring that
you wire the heater correctly for either single or three phase oper-
ation.
16. Using the torque wrench or a torque nutdriver (if available)
torge the nuts holding the wires, jumpers and bus bars to 16 in-lbs.
17. Ensuring that all non-essential personnel are clear of the area,
close the drain valve(s) and restore power and water to the unit.
Turn the unit on and allow it to fill normally.
18. Verify that there are no leaks around the heater. If there are,
attempt to tighten it down as the tub will change shape slightly as
it heats up.
19. Use the amp meter to take readings off of the power lines to the
heater, verifying the amperage draw to the machine data plate.
20. Wait until the heater contactor kicks out (meaning that the tub
has reached the appropriate temperature) and place the unit in
DELIME mode by flipping the switch on the back of the control box.
Allow the unit to operate for at least ten minutes to verify that there
are no leaks and that the heater is maintaining the tank tempera
-
ture.
21. If the unit appears to be operating correctly, return it to AUTO
mode and turn off.
