4-2.5 Accumulator
The accumulator may be installed at any convenient location within the dwelling,
outhouse, garage, loft or basement.
In normal circumstances the accumulator should be installed vertically. Where this is not
possible accumulators up to 240 can be installed horizontally by supporting it in a cradle
and ensuring provision is made to make it fully drainable.
The floor must give adequate support to the filled accumulator.
The accumulator must be protected from frost, particularly when it is sited in a loft,
outhouse or garage.
Note that space is required to the top of the vessel to access the pressure valve.
Provision must be made to enable the accumulator to be drained when required.
IMPORTANT The accumulator is supplied at 2 Bar pressure. It is
recommended to set the pressure at 1.5 Bar below the mains pressure
with a minimum of 0.5/0.8 Bar - see 4-5 and 5-5.1.
4-2.6 Scale Protection
IMPORTANT All installations should have a scale protection device fitted
and in areas known to have hard water, a water softening device is
strongly recommended.
GAH recommend and promote the use of scale prevention devices and water softeners in
areas that are known to have hard water. Installed correctly they prolong the life of
equipment and help prevent lime-scale formation in the pipework. Water Softeners
provide the advantages of soft water, as well as preventing scale build up on taps and
shower heads.
Water softeners and any mains fed system must be of adequate capacity and should be
installed with suitably sized hoses to prevent any possibility of flow reduction.
The location and position of the scale protection device or Water Softener should be as
the manufacturers recommendations.
4-2.7 Pipework
When all pipework has been installed, disconnect from the Dualstream components and
flush all pipework thoroughly.
When connecting to existing pipework remove all unwanted components, create new pipe
runs then flush thoroughly before connecting to the Dualstream components.
4-2.8 Dualstream Components
All Dualstream components and pipework are checked at the factory prior to dispatch,
however always check the connections for leaks on commissioning as transportation and
installation can cause joints to move.
Note
As Dualstream is a sealed system, the
pressure at the taps is not affected by the
height of the cold water storage.
GAH offer a range of quality Water
Softeners, for information contact
