SECTION 5: SERVICE PROCEDURES

VACUUM BREAKER REPAIR PARTS KIT

These dishmachines are equipped with vacuum breakers to serve as back-flow prevention devices. ASSE requirements specify what type of back-flow prevention is nec- essary on dishmachines. Vacuum breakers, unlike air gaps, have certain parts that have specific tolerances and design aspects that must be met in order to function properly.

Ecolab offers repair kits for replacing some of the wear items associated with vacuum breakers which will allow you to save money in that replacement of these parts can take place without removing the vacuum breaker from the plumb- ing 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

STEPS

1.Note: These instructions only apply to vacuum breakers (1/2” NPT and 3/4” NPT) as pictured below. The repair kits indicated in these instructions will only work on those style of back-flow preventers. If you have a machine with a different style of vacuum breaker, contact your Ecolab representative about replacement components.

Vacuum breaker

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.Needle nose pliers

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”.

IMPORTANT NOTES

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.Note: Even though the photos in these instructions show a vacuum breaker that has been removed from the plumbing assembly, these maintenance steps could be performed with it installed so long as the requirements in the section entitled “PREPARATION” have been met.

3.Remove the top cap by gripping firmly and turning to the left. The cap should come off after a few turns.

Removing the cap

4.Set the cap to the side.

5.Using the needle nose pliers, gently lift out the plunger and set to the side. Examine the brass seating surface inside the vacuum breaker. The plunger is required to sit flat on this sur- face so it must be free of defects, imperfections and the like. If there is debris, remove it. If it is chipped or cracked then the vacuum breaker must be replaced. Failure to do so may result in the vacuum breaker not working according to its design and could result in damage to the dishmachine.

JFT, JFT-S specifications

Jackson JFT is an advanced Java library designed for efficiently handling JSON data. Built on the popular Jackson core framework, Jackson JFT (JSON for Transformation) enhances Jackson's capabilities by providing powerful features for transforming JSON structures without losing the flexibility and performance that developers appreciate.

One of the main characteristics of Jackson JFT is its seamless integration with the Jackson ecosystem. It maintains compatibility with existing Jackson modules, allowing developers to leverage the extensive functionality of the framework. This integration ensures that users can easily transition to Jackson JFT, taking advantage of its additional features while retaining access to the wide range of tools already available in Jackson.

A key feature of Jackson JFT is its focus on JSON transformation. The library allows for easy manipulation and transformation of JSON data structures through a set of intuitive APIs. Developers can define transformations in a clean and readable manner, making the process of converting or mapping JSON data to different structures straightforward. This is particularly beneficial in scenarios where data might need to be reshaped for compatibility with different systems, APIs, or for front-end display purposes.

Jackson JFT also supports advanced data binding, allowing it to bind JSON data directly to Java objects and vice versa. This feature streamlines the process of parsing JSON data and is invaluable for applications that require frequent data interchange. The library handles various data types, ensuring that complex nested structures are managed efficiently.

Performance is another essential characteristic of Jackson JFT. The library is optimized to handle large datasets without significant overhead, making it suitable for applications with heavy data processing needs. Its efficient handling of memory and processing power results in faster transformations and reduces latency in web applications.

Furthermore, Jackson JFT ensures reliability and robustness in data handling. With built-in error handling and validation mechanisms, developers can easily identify issues in JSON data and ensure data integrity throughout the transformation process.

In summary, Jackson JFT stands out as a powerful tool within the Jackson ecosystem, designed to simplify JSON transformation and data handling. Its seamless integration, advanced data binding capabilities, performance optimizations, and reliability make it an ideal choice for developers looking to work with JSON data in Java applications. Whether it's for web services, data interchange, or application configuration, Jackson JFT provides a modern solution for effective JSON processing.
