Atmos Heating Systems

1 Introduction
Thank you for purchasing 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 reading 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 facing directly south, and mounted
on a slope of between 30 and 40 degrees to the horizontal. Any deviation from this
will result in less energy being collected, although 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 buildings shading the location of the solar collectors,
this will also reduce the performance. Ideally there should be no shading.
3.
DO NOT
fit the collector on a slope of less than 20 degrees. 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 boiling,
which is dangerous.
4. The storage tank
MUST
be located below the header of the evacuated tube collector.
5. The storage 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 greater than the pump head. If it is, the system will not work. A booster pump is
available from Atmos to give additional pump head if you make a mistake, but they
are not cheap.
6. The pipes from the collector to the storage 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 sag, 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).
