The SolarSmart requires a 230/240
V ~ 50 Hz supply, fused at 3 A if a 13 A 3-pin plug is used or a 5 A fuse if an
y other type of
plug is used.
To connect a plug:-
The colour of the wires in the mains lead may not correspond with the coloured mar
kings identifying the terminals in y
our plug.
In this case proceed as follo

Proviso:
WRAS Appro
val - Solar heating system components
. Compliance with the rele
vant requirements of the
Water Supply (W
ater
Fittings) Regulations 1999 has been assessed for this product only as a component of a heating system.
If it is to be installed as
part of a system using solar energy or g
round - or air - source heat pumps for pre-heating w
ater which is to be used as domestic hot
water
, the W
ater Fittings Regulations place a legal duty on the installer and user to ensure that the installation and operation of the
complete system prevents contamination of domestic hot w
ater by Legionella bacter
ia, which can gro
w in water stored at temper
atures
between 20° and 45°C
. Where disinf
ection by heating is relied on to meet this ob
ligation, infor
mation on minimum conditions f
or thermal
disinfection of Legionella bacter
ia can be found on the

1. Location -
Always ensure the f
ollowing clear
ances are availab
le around the units for ser
vicing:-
Cylinder -
T op:
100 mm, Bottom: 300 mm, Sides:
10 mm, Front:
450 mm.
Drain Back Unit -
T op:
100 mm, Bottom: 100 mm, Sides :
10 mm, Front:
450 mm.
2. Mains F
ailure -
In the event of an electr
ical supply failure the system will not oper
ate. When the supply is restored, the
system will return to nor
mal operation.
If the mains water supply f
ails, there will be no hot w
ater from the taps.
3. Pressure Relief
Valves -
If the hot water system o
verheats and steam or w
ater is discharged from the pipe connected to the
tundish, turn the Solar system off and contact y
our Installer. Y
our Installer should have told y
ou where these pipes terminate
.
4. Hot
Water -
T o pre
vent v
ery high temper
atures at the hot water taps
, the Installer should have fitted a ther
mostatically
controlled mixing valv
e after the combination boiler.
5. Hot Piping -
The temperatures of pipe
wor
k from the collector panel, drain bac
k unit and solar cylinder can be ver
y high.
Therefore all Solar system pipe
wor
k should have been insulated to not only reduce heat loss
, but more impor
tantly to prevent
injury from b
urns
. Ensure y
our Installer has done this!
6. Fr
ost -
Always ensure the room/area where the v
arious par
ts of the solar system have been installed are protected from frost.
7. Holida
ys -
The SolarSmar
t system
uses a
ver
y small
amount of
energy for
its oper
ation and
during
normal
vacations
(1-2 w
eeks)
we recommend that the system is left s
witched ON.
If hot water is not used f
or an extended per
iod of time or the property is v
acant then we recommend the system is s
witched
off and the cylinder is drained at the dr
ain point provided.
Further details of this procedure can be f
ound in the Installation and
Servicing Instr
uctions alternativ
ely contact your installer or engineer
.
8. Ser
vicing -
T o maintain efficient and saf
e operation of the SolarSmar
t system, it is recommended regular inspection and
checks are carr
ied out.
9. Electric
Immersion
Heater -
The
facility
to fit
an electr
ic immersion
heater is
availab
le which
can be
used to
provide
additional
heat to the cylinder contents if required.
If you contact the Alpha Helpline (T
el: 0844 871 8764) f
or advice, y
ou will be asked f
or the serial n
umber of your solar cylinder
.
The serial n
umber of the cylinder is located on lefthand side of the case and on the bottom.
