Steam can escape from the expansion relief valve of the solar
pump unit if the system is shut down. To avoid injuries an
expansion relief valve must be connected to a collecting
container with a hose line
In order to ensure a seamless operation of the product, the
safety valve should be cleaned periodically and checked for
proper functions. In areas with very calcareous water the calk
residuals on the valve should frequently be cleaned off.
The product shall be installed in an area where children cannot
access.
Immersion heater is intended as standby device for water
heating and should not be used simultaneously.
In areas with hard water hot water temperature should not
0
exceed 45 C to avoid calcification.
This product is designed for water heating purposes using
solar energy and it may not be changed or modified in any
way. It should be installed by a qualified person, who should
observe the applicable local regulations and the building
code.
4. SITING
Correct siting is critical for the effective operating of a solar water heater, the following
being important guidelines:-
•
Orientate the principal axis of the units in a North/South direction, with the collector
facing the equator. This orientation is important to maximise sun exposure on the
collector as it tracks on its East /West axis throughout the day.

•
Tilt at approx 15 . In order to optimise irradiation and also assist in the thermosyphon
process. Heater units should never be laid flat.
•
Avoid any shade, especially between 10am and 4pm. Shade reduces system
efficiency.
Preferably, solar panels should be installed on roofs where solar irradiation is highest and
they are also less exposed to damage. If this is not possible, a protected ground sitting is
acceptable.
