1.0 IMPORTANT INSTALLATION POINTS
1.1
The Elson EBW25 stores and dispenses water at or close to boiling point at all
times it is switched on. Due caution must be taken when choosing a location
for the product to minimise misuse. Locate the unit over a draining board
NOT over the sink or basin.
1.2
Push fi t connectors DO NOT grip chromed or stainless pipe.
1.3
The EBW25 is a vented water heater. The vent pipe must never be
blocked or obstructed, it must be a minimum of 15mm outside diameter
pipe. Where the vent pipe length exceeds 3m the pipe diameter should be
increased. The vent pipe must be laid to a continuous fall and discharge in
a safe and visible position; it must discharge via a tundish or fi nish a
minimum of 20mm above a draining board. The vent pipe material must
be capable of conveying boiling water. The vent pipe must never be
connected directly to a soil pipe.
1.4
Wherever possible the EBW25 should be supplied directly from a rising
main. If fed from a cold water feed cistern, the cistern must comply with the
Water Regulations Guide (clause R27.2). It should be noted that water
quality may be reduced when supplied from a cistern and additional forms of
water pretreatment may be necessary.
1.5
In hard water areas, heated water will produce lime scale which will be
deposited within the heater. If this is not regularly removed it will impair the
operation of the heater. Where rapid and excessive scale build up is likely to
occur the use of a proprietary scale reducing device may be benefi cial.
1.6
The installation must be carried out in accordance with the relevant
requirements of:
• The appropriate Building Regulations either The Building
Regulations (England & Wales), The Building Regulations (Scotland) or
Building Regulations (Northern Ireland).
• The Water Fittings Regulations or Water Byelaws in Scotland.
1.7
The EBW25 will adjust for ambient (room) temperatures of between 1°C and
40°C.
1.8
When not in use care must be taken to prevent it freezing; if thought to be
frozen it must not be switched on. It must be left to thaw and must then be
thoroughly inspected to ensure it is totally thawed and undamaged.
1.9
The unit is not suitable for installation in an area where a water jet could be
used.
