Application
The Sola thermostatic mixer tap has been independently tested by Buildcert Limited and certified
as meeting the requirements of the NHS D08 specification under the TMV3 Scheme as being
suitable for use on the following designations;
Wash Hand Basin
HP-W
Temperature Setting
Ensure that the basin tap is commissioned under normal system conditions. The basin tap MUST
be commissioned to suit site conditions and the desired outlet temperature set by the installer;
i With normal supply conditions established and the hot and cold water supplies running, open
the basin tap to its maximum temperature and leave running.
ii Remove the indice, retaining screw and handle by pulling away from the tap and the
temperature stop ring, see diagram on page 5.
iii Fully open the flow control and allow the outlet temperature to stabilise.
iv Temporarily refit the handle and using a digital thermometer it is possible to increase or
reduce the mixed water outlet temperature until 38˚C is re-established, by slowly rotating the
handle.
v Remove the handle and refit the temperature stop ring onto the splined section of the
cartridge at the maximum temperature position.
vi Refit the handle in the reverse order.
Installation
IMPORTANT -
The following instructions must be read prior to the installation of any Twyford
basin tap. The installer should also be aware of their responsibility and duty of care to ensure that
all aspects of the installation comply with all current regulations and legislation.
Flushing through water systems using certain chemicals may wholly or partially remove the
lubricant from the internal workings of the valve, which may adversely affect its performance. We
recommend that following a flushing of the system with chemicals, valves are checked for correct
operation.
1 It is essential that before installing a Sola thermostatic basin tap to ensure that the supply
conditions of the system, to which the tap is intended to be fitted, are checked to confirm
compliance with the parameters as quoted within the Technical Specification and conditions
on which the approval is granted i.e. verify supply temperatures, supply pressures, risk
assessment.
2 Consideration must be made for the possibility of multiple / simultaneous demands being
made on the supply system whilst the basin tap is in use, all practical precautions must be
made to ensure that the basin tap is not affected. Failure to make provision within the pipe
sizing etc. will affect the performance of the tap.
