1 Introduction
Thank you for purchasin an Atmos EasySolar hot water system. This will provides you
with free hot water for many years to come, provided that it is correctly installed and
maintained.
Most of us dislike readin installation manuals, and prefer to fit it and read later, so we
have summarised some of the 7 most important installation requirements below,
BUT, please do not use this as an excuse not to read the manual properly. Remember
that the warranty will be invalidated if the installation is not correct.
1. LOCATION; Ideally the solar collectors should be facin directly south, and mounted
on a slope of between 30 and 40 de rees to the horizontal. Any deviation from this
will result in less ener y bein collected, althou h between south east and south west
it will at most result in less than 10% loss of performance.
2. SHADING. If there are trees or buildin s shadin the location of the solar collectors,
this will also reduce the performance. Ideally there should be no shadin .
3. DO NOT fit the collector on a slope of less than 20 de rees. If you do the system will
not only lose performance, but the drain back action will be impaired. That means the
collectors will freeze and break in the cold winter. In the summer it will cause boilin ,
which is dan erous.
4. The stora e tank MUST be located below the header of the evacuated tube collector.
5. The stora e tank is fitted with a pump which has a 3m or 4m head. The vertical
distance between the base of the tank and the top of the solar collector MUST NOT
be reater than the pump head. If it is, the system will not work. A booster pump is
available from Atmos to ive additional pump head if you make a mistake, but they
are not cheap.
6. The pipes from the collector to the stora e tank MUST have a continuous slope down
towards the tank, otherwise the drain back will not work. They must be properly fixed
so that they cannot droop or sa , or be pulled down by someone.
7. PLEASE make sure you use the insulation provided on the red and blue pipes, and
make sure it is neatly and correctly fitted. Up to 20% of the heat collected by the solar
collector can be lost if the insulation is not fitted (or badly fitted).

3 Siting & requirements
When choosin the location for the stora e tank the followin needs to be considered:
• The vertical distance between the base of the tank and the top of the collectors
should not exceed the combined capacity of the stora e tank pump and any booster
pump that may be added to provide extra pump hei ht.
• The distance between the stora e tank and the appliance (combi boiler or hot water
cylinder) to which pre-heated water is supplied, needs to be kept as short as practical.
• The stora e tank needs to be sited on a firm horizontal surface that is able to take the
wei ht when the tank is filled with water (116k ). Atmos supply a brackets and shelf
set for optional wall mountin of the stora e tank.
• The followin are needed in the vicinity of the stora e tank:
o 240V electrical socket within 1.5 meter distance
o Water tap with ¾”bsp hose union connection within 2.5 meter distance
• It is preferable to locate the stora e tank and the connectin domestic water pipes in
a frost free room. If the tank is installed in an unheated space particular care must be
taken to protect the domestic water pipes a ainst freezin . See para raph 4.5.

4.1 Safety & insulation
Before you start work consider your own safety and that of others.
• The EasySolar hot water system has electrical parts. Apart from the adaptor which
plu s into the 240V socket, these parts are all low volta e (12V) and therefore
perfectly safe. However it is advisable to take care not to dama e any electrical
insulation and to avoid electrical parts becomin wet.
• The heat exchan er and the flexible connectin pipes for domestic water are subject
to mains water pressure and can become hot. For this reason the flexible connectin
pipes for domestic water need to be insulated. Insulation for these pipes is included in
the assembly kit. The insulation must extend over the connections to the tank. Secure
the insulation with tape. Ensure that the tank and connectin pipes have cooled down
before any maintenance work is undertaken. The tank and connectin pipes can be
cooled down by drawin off hot water.
• The pipes connectin the stora e tank and the collectors can also become hot. The
red flow pipe needs to be insulated alon its full len th. Insulation for this pipe is
included in the assembly kit. Ensure that the pipes have cooled down before any
maintenance work is undertaken.
• Assemble all components accordin to the installation instructions and avoid
components ettin dama ed durin installation or subsequent use.
• Put in place sufficient safety measures when workin on the roof. Use scaffoldin if
necessary.

4.2 Storage tank
Connections
4.3 Domestic water connections
The flexible connectin pipes provided in the assembly kit are for the domestic water hot
and cold connections. Use the washers for sealin the connection between the flexible
pipes and the stora e tank. The blue connectin point is for incomin cold water and the
red connectin point is the outlet for pre-heated domestic water. The mains water
pressure should be no more than 8 bar. If the mains water pressure is likely to exceed 8
bar, a pressure reducin valve should be fitted before connection to the stora e tank.
4.4 Hard water
In areas of hard water (hardness in excess of 200ppm) an approved water conditioner
device must be fitted in accordance with the Buildin Re ulations. Atmos can supply a
suitable conditioner for fittin to the cold feed to the stora e tank. In areas of hard water,
failure to fit a suitable conditioner will invalidate the warranty.
4.5 Tank in unheated s ace
If the tank is installed in an unheated space particular care must be taken to protect the
domestic water pipes a ainst freezin . Insulation for the domestic water flexible
connectin pipes is supplied with the assembly kit. It may be necessary to apply
additional insulation to these pipes and to other domestic water pipes particularly if the
unheated space is subject to drau ht.

4.6 Protection of lastic i e and i e insulation
The red and blue collector pipes are made of plastic. It can occur that plastic pipes or
pipe insulation material is dama ed by rodents such as mice, rats or squirrels. Take
appropriate precautions to protect the pipes and insulation material from this kind of
attack if considered necessary.
4.7 Vented hot water systems
The Atmos EasySolar system can be used as a preheat tank with a vented hot water
system. The base of the cold water feed tank must be at least 1m above the base of the
EasySolar tank, and the cold feed to the hot water cylinder passes throu h the cold/hot
connections of the EasySolar tank. In most cases where the cold tank is in the roof
space, a platform will be required of stron construction in accordance with the current
standards.
4.8 Unvented hot water systems
The Atmos EasySolar system can be used to provide preheated water to an unvented
hot water cylinder. However the pressure reducin valve assembly as fitted on the cold
water inlet feed of an unvented cylinder must be fitted before the EasySolar tank, and
then the warm outlet from the EasySolar tank is connected to the cold inlet on the hot
water cylinder (see pa e 12)
4.9 Connection to combi boiler
The Atmos EasySolar hot water system can be used provide preheated water to a combi
boiler. However the followin points must be noted;
a) If the boiler is solar compatible (e Atmos HE32 InterCombi) it can be connected
directly to the cold water inlet as per the dia ram on pa e 11.
b) If the boiler is not solar compatible, but can accept cold water at 28 de C, a
Combisol valve must be fitted (available from Atmos)
c) In all cases for combi boilers which are not solar compatible, the installer should
check with the manufacturers that the boiler is able to accept cold water at 28 de C
inlet. If this is not acceptable, then an EasySolar system should not be fitted, or the
boiler should be chan ed to a solar compatible type.
