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 20 mm 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 pretreatment
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 (see Supreme
Maintenance Plan). 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 comply with the relevant sections of the
Water Regulations, Building Regulations and BS 7671 (IEE
Wiring Regulations) in force at the time.
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.
