4. Installation Requirement Notes:
IMPORTANT - PLEASE READ
This/these fitting/fittings needs/need to be installed in accordance with the following Installation
Requirements and Notes (IRN) to ensure they meet the requirements of the Water Supply (Water
Fittings) Regulations 1999 and the Scottish Byelaws 2004.
IRN R001
See text of entry for Installation Requirements or Notes.
IRN R006
This tap or combination tap is installed so that its base is no lower than the spillover level of the receiving
vessel (for example, a sink or washbasin), a Type AUK3 air gap is achieved which permits installation of the tap
in any premises where backflow protection up to Fluid Category 5 is required at the tap.
IRN R010 Schedule 2-15 (1)
Water supplies shall be reasonably balanced pressures from a common source (e.g. hot and cold supplies
both from the same storage or both from a supply pipe). Where the fitting is supplied from unbalanced
supplies (e.g. hot and cold supplies from separate sources) a
‘Listed’ single check valve or some other no
less effective backflow prevention device shall be fitted immediately upstream of both hot and cold water
inlets.
5. Installation
These taps are suitable for use at all supply pressures, however for optimum performance use both hot and cold
water supplies which should be reasonably balanced.
Operating pressures: Min 0.2 bar, Max 5.0 bar
Min 0.3 bar, Max 5.0 bar (J MBAS C)
Maximum static pressure: 10.0 Bar
If the fitting is installed at low pressure (tank fed), then the minimum distance from the underside of the nozzle to
the cold water tank should be at least 2 metres* to ensure adequate performance.
This mixer should be installed in compliance with Water Regulations.
For further details please contact your local Water Authority.
*J MBAS C will require a minimum distance of 3 metres to ensure adequate performance.
