4Vent (A) any air from the boiler heat exchanger using a suitable container to collect any water. Ensure tube outlet (B) is directed away from the fan or any other electrical component to prevent any water damage. Also place a suitable cover over the fan to prevent any spillage of water

on to electrical connections. Ensure the cover is removed after venting.

•The boiler integral expansion vessel is pre- charged to 0.75 bar (equal to a static head of 7.5m (22ft). A Schraeder type valve is fitted to the expansion vessel to allow for pressure adjustment if required.

•If an extra expansion vessel is fitted to the central heating return, adjust this to the same pressure as the appliance internal expansion vessel, refer to separate instruc- tions with the extra expansion vessel.

6Briefly open the pressure relief valve to test its operation.

7If required increase system pressure back to 1 bar.

8Rotate the adjustable pointer on the pressure gauge to record the set system pressure.

9Isolate and remove filling loop connection to system or if using the optional integral filling connection (C) (not supplied with the boiler) remove key (D) and place in

its storage position (E) on the bottom cover of the boiler.

•A pre-filling kit 7 716 192 282 is available for installations where the boiler will not be fitted immediately to the heating system. This allows the heating system and mains water connections to be filled and checked prior to boiler installation.

This kit can be used in conjunction with the optional filling loop 7 716 192 281(not sup- plied with the boiler).

Bosch Appliances has long been synonymous with quality and innovation in the kitchen. Among its notable offerings, the Bosch 24i Junior stands out as a compact yet powerful dishwasher that caters to modern household needs. This appliance is designed to provide efficient cleaning while conserving valuable space in smaller kitchens.

One of the key features of the Bosch 24i Junior is its compact size, measuring 24 inches in width. This makes it an optimal choice for apartments, smaller homes, or kitchens with limited space. Despite its size, it does not compromise on capacity, allowing users to load up to 12 place settings, making it suitable for families or frequent entertainers.

The Bosch 24i Junior incorporates advanced cleaning technologies that set it apart from traditional dishwashers. One of these technologies is the PrecisionWash system, which uses intelligent sensors to monitor the cleanliness of dishes throughout the wash cycle. This ensures that each item receives the optimal amount of water and detergent, resulting in sparkling clean dishes every time.

Energy efficiency is another hallmark of the Bosch 24i Junior. It operates on a low water consumption model, using only 2.9 gallons of water per cycle, which is significantly lower than many competitors. This not only helps lower utility bills but is also a step towards more sustainable living. The Energy Star certification further emphasizes its commitment to reducing energy usage without sacrificing performance.

Bosch has also integrated sound-dampening technology in the 24i Junior, ensuring that it operates quietly at just 50 dBA. This low noise level means that the dishwasher can run at any time of day or night without disturbing household activities.

User convenience is enhanced through features such as the ExtraScrub option, which provides a more powerful wash for heavily soiled items. The adjustable racks offer flexibility for loading larger pots and pans, while the foldable tines accommodate a range of dishware sizes.

In summary, the Bosch 24i Junior is a versatile and efficient dishwasher that is ideal for those with limited space. Its thoughtful design and innovative technologies make it a standout choice for anyone seeking reliable dish cleaning solutions without compromising on performance or efficiency. This model exemplifies Bosch's dedication to delivering cutting-edge appliances that fit seamlessly into modern lifestyles.
