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 70oC, 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,

Power connection
Input is for power connection, is for connection with ground .
Input ports
Input T1：PT1000 temperature sensor use for collector.
Input T2 ~T5: NTC10K, B=3950 temperature sensor, for measuring temperature of tank and
pipeline
Advice regarding the installation of temperature sensors:
Only original factory equipped Pt1000 temperature sensors are approved for use with the
collector, it is equipped with 1.5meter silicon cable and suitable for all weather conditions, the
cable are temperature resistant up to 280oC, not necessary to distinguish the positive and
negative polarity of the sensor connection.
Only original factory equipped NTC10K,B=3950 temperature sensors are approved for use
with tank and pipe, it is equipped with 1.5meter PVC cable, and the cable are temperature
resistant up to 105oC, not necessary to distinguish the positive and negative polarity of the
sensor connection.
All sensor cables carry low voltage, and to avoid inductive effects, must not be laid close to
230 volt or 400 volt cables (minimum separation of 100mm)
If external inductive effects are existed, e.g. from heavy current cables, overhead train cables,
transformer substations, radio and television devices, amateur radio stations, microwave
devices etc, then the cables to the sensors must be adequately shielded.
Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s length
is up to 50m, and then 0.75mm2 cable should be used. When cable’s length is up to 100m,
and then 1.5mm2 cable should be used.
