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 -

 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
