INTRODUCTION
OPERATING CONDITIONS OF USE AND COMPLIANCE
Thank you for choosing this Roper Rhodes product. This guide covers the installation and
commissioning of the shower valve.
This shower valve must be installed in accordance with the Water Supply (Water Fittings) Regulations
1999. We recommend this product should only be fitted by a qualified plumber.
Before installation the operating conditions of use must be checked. The table below contains
details of the necessary conditions of operation. This valve is suitable for high pressure (BS1111)
operating conditions. Valves cannot operate effectively where a hot or cold pressure system crosses
the boundaries of the two ranges. In addition the maximum ratio of unbalanced hot and cold water
pressures for the valves to operate effectively is 2:1. Hot or cold pressure must be reduced or boosted
so as to work within the required range.
These shower valves are suitable for use with all water supply systems up to a maximum of 5.0 Bar.
Operating pressures above 5.0 Bar will require the installation of pressure reducing valves.
The valve must be installed so that it is readily accessible for commissioning and maintenance. The
valve is supplied with isolation valves on both the hot and cold inlets so as to allow the valve to be
commissioned and tested correctly. The valve is fitted with integral check valve cartridges which
command the water supply, therefore the thermostatic valve is protected against cross-flow due to
unbalanced line pressures as required by the Water Supply (Water Fittings) Regulations 1999.
