Installation
3 The supply system to which the Sola thermostatic basin tap is to be installed into must be
thoroughly flushed and cleaned to remove any debris, which may have accumulated during
the installation. Failure to remove any debris will affect the performance and the
manufacturer’s warranty of the product.
In areas that are subject to aggressive water, provision must be made to treat the water
supply prior to the supply entering any product.
4 The maximum flow rate of the tap will only be achieved when the supply conditions are
achieved as quoted within the Technical Specification, with a flow condition under 1 bar
differential pressure.
5 This thermostatic mixer tap has been designed for basin mounting. It is essential that
access to the tap is not obstructed for commissioning, testing, or any future maintenance
that may be required.
6 The hot and cold water supplies must be connected to the tap strictly in accordance with
these instructions i.e. hot water supply to the hot port of the tap.
7 In a situation where one or both of the water supplies are excessive, it is possible to fit a
pressure reducing valve or a flow regulator to reduce the pressure(s) to within the limits as
quoted previously.
8 Any thermostatic basin tap must be fitted with a back flow prevention device, such as check
valves (supplied) to prevent the cross contamination of supplies.
9 Independent filters/check valves and isolation valves must be fitted in conjunction with the
SF1139CP basin tap, as close as practically possible to the water supply inlets.
The SF1139 has an integral filter and check valve in the check valve housing on the hot and
cold supplies.
10 It is essential that the Sola thermostatic basin tap should not be installed in situations
where there is a possibility of the tap being deprived of water or where demands for water
are greater than the actual stored supplies.
11 To ensure that the performance levels of the Sola thermostatic basin tap is maintained
(in the event of cold water failure), the temperature of the hot water supply at the point of
entry to the valves must be a minimum of 10˚C above the commissioned mixed water
discharge temperature.
12 The Sola thermostatic basin tap must not be subject to any extreme temperature variations
either during the installation or under normal operating conditions.
