Water Requirements
Under no circumstances must the Power Shower be connected to
the mains cold water supply, or to a combination hot water system.
For correct operation of the Bristan 1000 Power Shower both hot
and cold supplies to the unit must be gravity fed, at equal pressures,
from a cold water storage tank and hot water storage cylinder.
We recommend a minimum 112 litre (25 gallons) cold water storage
tank. Please ensure compliance with all Water Regulations.
Please ensure maximum supply head of 10 metres, minimum 1
metre to the shower head when positioned on the wall.
It is recommended that the hot water supply is at a temperature of
60°C, in line with British Standard 6700, British Water Regulations,
and Plumbing Code of Practice.
Do not use jointing compounds, or solder within 300mm of the unit.
Before proceeding with the installation of this unit, check that your
site requirements allow the shower unit when positioned on the
wall to be a minimum of 1 metre below the bottom of the cold water
storage tank.
All plumbing should be completed before any electrical connections
are undertaken.
The unit can be connected to a combination cylinder system
providing it has cold water storage capacity of 112 litres (25 gallons).
When connecting pipe work avoid using elbows: sweep or formed
bends will ensure optimum performance.
Do not run pump dry as this will damage the internal seals and
invalidate the warranty.
All pipe work to the unit should be 15mm. Non-restrictive isolating
valves must be fitted on hot and cold supply pipes.
Do not position unit in areas subjected to freezing conditions.
The temperature of your stored water must not exceed 65°C. A
stored water temperature of 60°C is considered sufficient to meet
all normal requirements in line with the British Standard 6700.
Warning - All connecting pipe work should be earthed.
Procedure - Plumbing Connections
Isolate mains water and electrical supplies
To empty the pipe work open the hot and cold water taps.
Make your connection into the hot water supply pipe from the
cylinder, ensuring that it is the first draw-off (below the expansion
pipe tee) to minimise the effects of water draw offs elsewhere in the
house, and a minimum of 1 metre from the base of the cold storage
tank and the top of the hot water cylinder.
If this is not possible, a direct connection must be made from the
hot water cylinder with a cylinder flange.
The cold water supply should be taken directly from the cold storage
tank, and must be positioned 60mm below the cold feed connection
to the hot water cylinder. This should not be directly beneath the ball
valve as aeration of the water going to the shower could cause pump
damage.
Run hot and cold pipe work to the unit position.
