SR971,SR972 Solar station operation manual
-------------------------------------------------------------------------------------------------------------------------------------

Note:
In order to avoid jaming the degital flow meter and in result to displays no flow
on solar station, the filter ( A) must be installed on the return and flow pipeline of solar
station.
All devices connected to the controller must conform to the technical specifications of
the controller
• Assembly, Installation and maintenance work may only be performed by
properly qualified and authorized personnel with a generally recongnized qualification.
The solar station must be installed indoors, prior to installation, remove sealing caps
from solar station.
The Maximum distance between solar station and water tank is 300mm,keep top edges
of solar station and top edge of storage tank.
Pre-setting, installing and adjusting the expension tank as per the installation and
operation instructions for
“expansion tank”, the corrugated connection pipe for the
expansion tank does not need thermal insulation.
Safety valve: Risk of scadling from hot steam with discharge from the safety valve due
to heating and excess pressure in the hydraulic pipes. Drain off discharge from the
safety valve using a copper pipe correctly and in an eco-friendly way, according to valid
technical regulations and load codes, do not allow solar fluid to leak into the
environment.
Be careful of scald from hot fluid. Maxiumu temperature of collectors during
filling/leak check or installation/maintenance work should be below 70
o
C, allow
collectors to cool down if necessary.
Please ensure hydraulic connections are pressure-tight, connetions pipe should be
insulated, Unused connections must be sealed tight with a suitable end plug.
Air-seperator: if the system is pressue-tight ( no leakage), connect the power supply to
the solar controller, using the manual mode of controller to circuit system for 15 minutes,
then switch-off power supply, solar fluid is heated gradually, air dissolveed in fluid is
released out, through air
–seperator to release air. If necessary ,repeats this process
until no more aire is vented out. If the system pressure drops due to over air release,
then it is necessary to refilling fliud to the required pressure.
After filling the system, please check safety valve accoring to its manual.
All safety regulations for working on the power supply are valid, All installtion and
maintenace work should be performed when power is switched-off,
