Installation
3 The supply system to which the Sola shower valve 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 shower valve 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 These thermostatic shower valves has been designed for exposed or concealed mounting.
It is essential that access to the shower valve will not be obstructed for commissioning,
testing, or any future maintenance that may be required.
6 The hot and cold water supplies must be connected to the shower valve strictly in
accordance with these instructions i.e. hot water supply to the hot port of the shower valve.
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 shower valve must be fitted with a back flow prevention device, such as
check valves to prevent the cross contamination of supplies.
9 Independent filters/check valves and isolation valves must be fitted in conjunction with the
Sola shower valve, as close as practically possible to the water supply inlets.
The Sola shower valve has integral filters and check valves in the inlet connection on the
hot and cold supplies.
10 It is essential that the Sola shower valve should not be installed in situations where there is
a possibility of the shower valve 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 shower valve 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 shower valve must not be subject to any extreme temperature variations either
during the installation or under normal operating conditions.
