INSTRUCTIONS.

 

 

 

 

 

 

FLUSHING (Central Heating):

 

 

 

 

 

 

1 Switch off the boiler (A).

 

 

 

 

 

 

 

Open all drain cocks (B) and drain the

system (C) while the appliance is hot.

 

 

 

 

 

2 Close drain cocks (D) and add a suitable

 

 

 

 

 

 

 

 

 

 

 

 

 

flushing agent (E) at the correct strength for

 

 

 

 

 

 

 

the system condition in accordance with the

 

 

 

 

 

 

 

manufacturer's instructions.

 

 

 

 

 

 

3 Run the boiler/system at normal operating

 

 

 

 

 

 

 

temperature (F) for the time stated by the

 

 

 

 

 

 

 

manufacturer of the flushing agent (G).

 

 

 

 

 

 

4 Drain (H) and thoroughly flush the system to

 

 

 

 

 

 

 

remove the flushing agent and debris ( I ).

collect any water (N).

 

 

 

 

 

 

Ensure tube outlet (O) is directed away

 

 

O

 

 

 

 

 

 

 

 

 

 

from the fan or any other electrical

 

 

 

 

 

 

 

component to prevent damage. Also

 

 

 

 

 

 

 

place a suitable cover over the fan to

 

 

 

 

 

 

 

prevent any spillage of water onto

 

 

 

 

 

 

 

electrical connections. Ensure the cover

 

 

 

 

 

 

 

is removed after venting.

Set all controls to maximum (R).

 

 

 

 

 

 

 

Record the date when the inhibitor was

 

 

 

 

 

 

 

added to the system on the guarantee card.

 

 

 

 

 

 

NOTE: The concentration level of inhibitor in

 

 

 

 

 

 

the system should be checked every 12

 

 

 

 

 

 

months, or sooner if system content is lost.

 

 

 

 

 

 

The addition of sealing agents to the system

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.
