OPERATING CONDITIONS
This heater is intended for use only in a domestic hot water system with an Indirect or direct copper cylinder
conforming to BS 699, BS 1566, BS 3198 or similar specification and operating at a maximum temperature of
65 degrees centigrade. No warranty is given or implied for uses other than as part of a domestic hot water
system.
FITTING IN CYLINDER
The heater is to be fitted to the tank using the washer supplied (or a WRAS approved non-asbestos washer
of at least 1.5mm in thickness) and tightened to a minimum torque of 30 Nm. To ensure a 'leak-free' joint, it
is important that both flange faces are clean and free from all traces of old washer.
WATER HARDNESS
To obtain maximum heater service life it is important to select the correct type of immersion heater for the
local water conditions.
The 'Popular' range of Immersion heaters, where the sheath is of "COPPER' material, are designed to
operate in 'Salt' to 'Neutral' water or where water softening equipment is used.
The 'Anti-Corrosive OR Aqualoy' Immersion heaters, where the sheath is of 'STAINLESS' type material, are
designed to operate in 'Neutral' to 'HARD' water where the build-up of limescale is likely to occur.
POWER SHOWERS OR SHOWER PUMPS
Where a second hot water outlet is fitted to the storage cylinder (hot water tank) to supply a shower pump
or power shower, the guarantee / warranty does NOT cover defects arising from the operation of the heater
when not totally immersed in water.
LIMITATIONS
Any use other than that as listed above will invalidate the product guarantee unless the details of the
operating environment are subject to a contractual agreement.
The guarantee / warranty does NOT cover defects arising from accidental damage, misuse, wear and tear,
inappropriate selection to suit the local water conditions, incorrect connection or incorrect supply voltage.
