Bristan 1500 설치 지침 및 사용자 설명서

Water Requirements

Under no circumstances must the Power Shower be connected to the
mains cold water supply, or to a combination boiler, or pressurised
hot water system.
For correct operation of the Bristan Thermostatic Power Shower both
hot and cold supplies to the unit must be gravity fed, at nominally
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.
Please note, when using this unit in 'gravity' shower mode, without the
boost button depressed, ensure you have a minimum of 1 metre head
from your shower head to the bottom of your cold water tank.
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 and handset when positioned
on the wall to be a minimum of 1 metre below the cold water storage
tank.
All plumbing should be completed before any electrical connections
are undertaken.
The unit can be connected to a cylinder system providing it has cold
water storage capacity of 112 litres (25 gallons).
Do not run shower dry as this will damage the internal seals and
invalidate the warranty.
All pipe work into the unit should be 15mm. Non-restrictive isolating
valves must be fitted on hot and cold supply pipes. When connecting
pipe work avoid using elbows: sweep or formed bends will ensure
optimum performance.
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.
