WATER SYSTEMS & PIPEWORK

PLASTIC PIPEWORK:

• Any plastic pipework must have a polymeric barrier with 600mm (minimum) length of copper or steel pipe connected to the boiler.

• Plastic pipework used for underfloor heating must be correctly controlled with a thermostatic blending valve limiting the temperature of the circuits to approx. 50°C. The pipework from the boiler to the blending valve must be in copper or steel (protected from corrosion).

PRIMARY SYSTEMS CONNECTIONS/VALVES:

 

 

•

All system connections, taps and mixing

 

 

 

valves must be capable of sustaining a

 

 

 

pressure up to 3 bar.

-PRE

INSTALLATION

•

Radiator valves should conform to

 

 

 

BS2767:10.

 

 

•

All other valves should conform to BS1010.

 

 

•

Thermostatic radiator valves (TRV’s) must be

 

 

 

used on all radiators within the sleeping

 

 

 

accommodation but not the radiator where

 

 

 

the room thermostat is sited. This must be

 

 

 

fitted with lockshield valves and left open.

 

 

• A drain cock is required at the lowest point

 

 

 

in the system.

 

 

•

An air vent is required at all the high points in

 

 

the system.

 

 

NOTE: The boiler is equipped with an automatic

 

 

internal by-pass.

 

 

SHOWERS/BIDETS:

• If a shower head can be immersed in water or comes closer than 25mm from the top edge of a bath or shower tray spill over level then an anti-siphon device must be fitted to the shower hose.

• Bidets with direct hot and cold mains water can be used (with the approval of the local water authority) and must be the over rim flushing type with shrouded outlets to prevent the fitting of hand held sprays.

SEALED PRIMARY SYSTEM:

• The CH sealed system must be filled using a WRAS approved filling loop or comply with the diagram opposite for system fill.

RR• Where the system volume is more than 100 litres or exceeds 2.65 bar at maximum heating temperature, an extra expansion vessel (B) must be fitted as close as possible to the appliance in the central heating return.

• Pressurise the extra expansion vessel (B) to the same figure as the expansion vessel built into the appliance.

• Do not use galvanised pipes or radiators.

28i junior, 24i junior specifications

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.
