Important Installation Points - Heatrae Sadia Supreme 150SS Fitting Instructions And User Manual

1.0 IMPORTANT INSTALLATION POINTS

1.1 The Supreme 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 fit connectors DO NOT grip chromed or stainless pipe.
1.3 The Supreme 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, visible position; it must
discharge via a tundish or finish 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 Supreme 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 pre-treatment may be
necessary.
1.5 In hard water areas, heated water will produce limescale 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 beneficial.
1.6 The installation must be carried out in accordance with the relevant
requirements of:
• The appropriate Building Regulations either The Building
Regulations, The Building Regulations (Scotland) or Building
Regulations (Northern Ireland).
• The Water Fittings Regulations or Water Byelaws in
Scotland.
1.7 The Supreme 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 thorougly 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.
