1. Your Grant DuoWave Plus Solar
vented hot water cylinder has been
designed to give many years of
trouble-free service and is made
from hygienic high grade stainless
steel. All models include a 3 kW
electric immersion heaters for times
when your central heating 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 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 the
Temperature & Pressure Relief (T&P
Valve) valve 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, 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 water
cylinders.
