way, according to valid technical regulations and local codes, do not allow solar fluid to
leak into the environment.
Be careful of scald from hot fluid. Maximum temperature of collectors during filling/leak
check or installation/maintenance should be below 70
o
C, allow collectors to cool down
if necessary.
Please ensure hydraulic connections are pressure-tight, connections pipe should be
insulated, and unused connections must be sealed tightly with a suitable end plug.
Air-separator: if the system is pressure-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 dissolved in
fluid is released out, through air
–separator to release air. If necessary, repeats this
process until no more air is vented out. If the system pressure drops due to over air
release, then it is necessary to refilling fluid to the required pressure.
After filling the system, please check safety valve according to its manual.
All safety regulations for working on the power supply are valid, All installation and
maintenance work should be performed when power is switched-off.
