5.2 Installation requirements
Water supply
In an unvented system the pressure and flowrate is
directly related to the incoming water supply. For this
reason it is recommended that the maximum water
demand is assessed and the water supply checked
to ensure this demand can be satisfactorily met.
We suggest the minimum supply requirements
`
should be 0.08MPa (0.8 bar) pressure.
A 15mm cold water supply is recommended.
`
The higher the available pressure and flow rate
`
the better the system performance.
The water supply must be of wholesome water
`
quality (Fluid Category 1 as defined by the Water
Supply Regulations 1999).
Outlet/terminal fittings (taps,etc.)
The product can be used with most types of
`
terminal fittings.
It is not recommended for supplying a shower.
`
All fittings, pipework and connections must have
`
a rated pressure of at least 8 bar at 80°C.
