Installation Requirements
It is important to ensure that the water supplies to your taps and mixers are connected in accordance with current Water
Regulations and good plumbing practice.
It is Wolseley’s recommendation and good plumbing practice that the supplies of hot and cold water to the products
should be equal (balanced) pressures in order to provide a consistent flow. Supplies should be from a common source.
Either mains or tank fed. If supplies are not equal pressures then non return valves should be fitted (not supplied).
This product has been designed to function on all types of water of water systems.
Please note: if a pump is to be installed to boost gravity supplies please refer to the pump manufactures instructions.
The hot and cold inlets for any of the products are hot on the left and cold on the right when viewed from the front of
the fitting. It is our recommendation and good plumbing practice that a service valve also should be installed up stream
in the inlet supply lines.
Pipe Connections
IMPORTANT. Before making any inlet pipe connections all supplies MUST be thoroughly flushed to remove any
debris. Failure to do so could result in damage or low flow from the fitting.
General Installation Notes
• Care must be taken during installation to prevent any risk of damage to the product or injury to installer.
• Installation must be carried out by a qualified and competent person and in accordance with the instructions supplied.
• Installations must comply with all Local and National Water Authority Regulations and Building/Plumbing
Regulations.
• Ensure that you have read and understood all sections of this manual before installation.
Water Supply Temperature & Pressures
Hot Water Temperature Range Recommended 60-65˚C
Cold Water Temperature Range Recommended 10-15˚C
Operating Pressure:
Minimum: 0.2 Bar
Maximum: 5.0 Bar
This pressure rating is determined by the manufacturer using soft water under test house conditions and may differ
from site conditions.
Always maintain a 10˚C difference between hot system temperature and maximum hot setting of valve.
Hot and Cold Maximum pressure differential should be no more than 2 bars. If this limit is exceeded, fit a pressure
reducing valve (not supplied) must be fitted to the higher pressure water supply before the mixer valve.
Operating pressures on hot and cold supplies should be kept as even as possible in order to ensure the maximum
efficiency of the mixer.
When water pressure is higher than 5 bar a pressure reducing valve (not supplied) must be fitted before the mixer.
Flow restrictors (not supplied) can be fitted into the wall unions to reduce water consumption on high pressure system.
SAFETY NOTE
Before starting any new installation please check prior to drilling wall that there are no concealed
electrical wires or water supply pipes.
We recommend this is checked with the aid of an electronic detector.
When using power tools please wear eye protection.
