SECTION 5: SERVICE PROCEDURES

RINSE SOLENOID VALVE REPAIR PARTS KIT

These dishmachines are equipped with electrical solenoid valves to allow for automatic fill and rinse. These valves are designed to specific tolerances and design aspects that must be met in order to function properly.

Jackson offers repair kits for replacing some of the wear items associated with solenoid valves which will allow you to save money in that replacement of these parts can take place without removing the solenoid valve from the plumbing assembly.

The instructions provided here are for maintenance personnel 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 autho- rized personnel should ever perform any maintenance procedure on the dishmachine!

PREPARATION

1.Power must be secured to the unit at the service breaker. Tag or lock out the service breaker to prevent acci- dental 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.

TOOLS REQUIRED

The following tools will be needed to perform this maintenance evolution:

1.Small flathead screwdriver

2.Medium flathead screwdriver

2.Needle nose pliers

3.5/16” nutdriver

4.Channel locks

5.12” pipe wrench

TIME REQUIRED

It is estimated that it will take (1) person twenty min- utes to perform this task, not including all of the items indicat- ed in the section entitled “PREPARATION”.

STEPS

1.Remove the top screw with the 5/16” nutdriver. Remove the screw and the data plate and set to the side.

Removing the top screw

2.With the top screw and data plate removed, grasp the sole- noid coil and gently pull up. The coil should slide up, allowing you to remove it from the valve bonnet. If you are wanting to replace the coil, continue on with Step 3. If you are wanting to replace some of the internal components of the valve, proceed to step 12.

IMPORTANT NOTES

Removing the coil

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

2.The procedures demonstrated in this manual are shown being performed on an AJ-44C rack conveyor dishma- chine. The actual maintenance steps, however, apply to any Parker style solenoid valve found on a Jackson dishmachine.

3.NOTE: Replacing the solenoid coil requires working with the wiring of your machine. It is important that all wiring main- tenance be performed by qualified personnel. Always verify the wiring steps presented in this instruction with the schemat- ic that shipped with the unit. A current schematic can also be found in the unit’s installation manual. Before beginning any step that involves working with wiring, ensure that the steps located in the section entitled “Preparation” have been per- formed. Power must be secured to the machine at the service breaker. Failure to do so could result in severe injury to main- tenance personnel.
