10.1 User Instructions
1. Your Grant DuoWave Solar or
DuoWave HP unvented hot water
cylinder has been designed to give
many years of trouble-free service
and is made from hygienic high
grade stainless steel. The Indirect
models include two 3 kW electric
immersion heaters for times when
your central heating or heat pump is
switched off, during the summer for
instance.
2. The flow temperature of the hot
water can be set to your
requirements on the immersion
heater up to 60°C and the indirect
system dual thermostat up to 65°C.
These temperatures should not be
set any higher otherwise nuisance
tripping of the high limit thermostat
will occur. If you are in any doubt,
these adjustments should be best
left to a qualified electrician.
3. When a hot tap is turned on there
may be a short surge of water, this is
quite normal with unvented systems
and does not mean there is a fault.
4. When you first fill a basin the water
may sometimes appear milky. This
is due to very tiny air bubbles in the
water, which will clear very quickly.
If water is seen to flow from either the
Temperature & Pressure Relief (T&P
Valve) valve or the Expansion Relief
Valve (EV) on the cylinder seek expert
advice immediately.
If the water is flowing from the T&P
Valve, immediately:
Shut off the electrical supply to the
immersion heater(s)
Shut down the boiler
Switch off ALL other heat sources to
the cylinder e.g. solar, heat pump, etc.
DO NOT SHUT OFF THE WATER
SUPPLY TO THE CYLINDER.
Contact your installer to check the
system.
IMPORTANT
Do NOT tamper with any of the Safety
controls fitted to the cylinder. If you
suspect a fault always contact a
COMPETENT
installer who is
QUALIFIED
to work on unvented
water cylinders.
