Water Connections - Vidalux Hydro Plus Series Installation And Operating Manual

Water Connections

This product requires a hot and cold water supply. Your Hot and Cold water supply pipes should ideally
be fi nished about 1 meter above the fl oor centrally in the corner and fi nished with 15mm compression
isolating valvea. The shower will require two braided fl exible hoses that connect to these water supply
pipes from the shower valve.
WATER PRESSURE: 1-3 bar (ideally above 2 for optimum results)
WATER FLOW: above 7.5 litres per minute
Important Note Do not exceed 3.4 BAR pressure under any circumstances. Warranty is void if so as damage will
occur. If you have a combi sup ply, please use a pressure reducing valve if required to lower the BAR pressure to the
Fitting Isolating valves is recommended as this makes service access easier than locating the house Stop
Cock. Additionally Isolating valve enable you to disconnect water to the shower if you are away from
home for long periods of time.
Combination boiler installation and PEV's
This product does not normally require a Pressure Equalising Valve (PEV) as it uses the latest generation
of shower valve Thermostatic Cartridge, which enables it to handle un-balanced water pressures itself, to
provide accurate temperature control.
This shower product can be connected to Combi Boiler system that provide suitable water pressure and
water fl ow rates.
Gravity Fed and Shower Pumps
Where the water is supplied by a hot water cylinder (gravity fed type systems) a shower pump should
be installed. Ideally a shower pump rated over 2 bar supplying just the shower is recommended,
or alternatively a pump of higher specifi cation can be fi tted to supply multiple showers within the
property.
When choosing a pump, a twin impeller pump is recommended as this will ensure both the hot and
cold water is of the same pressure. (You must seek further advise from a plumber to correctly spec the
right shower pummp for your set-up
Always refer to the manufacturers instructions regarding shower pump installations and choose the
correct type for your particular situation (negative head/positive head etc). All pipe work between the
storage tank, cylinder and to the pump should be 22mm and the shower positioned at least 250mm
below the header tank. Please note that locating the pump further from the shower and cylinder may
reduce the eff ectiveness of the pump and will certainly reduce the output pressure of water.
Ensure the pump is correctly installed and commissioned. Failure to fi t the pump in accordance with the
manufactures instructions may result in inadequate water supplies and lead to pump pulsing etc.
Maximum pressure: The shower requires water pressure up to but not exceeding 3 bar.
Exceeding this maximum rating may damage the product and will invalidate your Guarantee.
