Initial operation
Initial operation
After installing the other components such as flow
pipe, return pipe, insulation, pump group, expansion
tank and controller, the installation can be put into
service. Perform a leak test and complete the com-
missioning log.
Protect the collectors from direct sunlight if the filling
of the installation is not carried out within five days
after completion of the assembly.
Inspections within the first two weeks of
operation
• bleeding the solar circle
• control system pressure
Instructions for the operation of the
installation
Carry out changes to the scheme and other system
components only after consultation and with inputs
from your specialized partner.
Ensure that an appropriate safety valve is mounted
whose opening pressure is not exceeding the maxi-
mal operating pressure of the collectors.
Furthermore, do not install shut-off valves which may
affect or prevent the funtion of the safety valve.
Carry out maintenance and inspections with appro-
priate caution.
Certain components may reach temperatures up to
200 °C. There is a risk of burns.
It is absolutely necessary to make sure that the back
flow temperature is never lower than the ambient tem
-
perature. If necessary, take appropriate measures (e.
g. increase of back flow temperature to at least
30 °C).
Regular inspections
Solar systems should be reviewed at intervals to be
determined in addition to the function control by the
operator.
The maintenance intervals of the system will be de-
fined during commissioning.
An annual review is recommended. The following components
must be checked for proper function (if installed):
• solar collectors
• solar circle
• heat transfer liquid
• solar storage
• solar regulator incl. circulation pump
• supplementary heating system
• expansion tank
Unscheduled maintenance
Depending on the location of the installation, environmental in-
fluences may cause soiling on the collector glass (dust, pollen
etc.). If necessary, clean the glass exclusively with clear water
to ensure optimal light transmission.
If it is necessary to free the system from snow or ice, only use
non-metal cleaning equipment such as brooms with due care.
Only walk on roof areas in compliance with all safety aspects.
Heavy condensation may occur on the interior side of the glass
when defrosting while the collectors are covered with snow.
It is absolutely necessary to free the collectors from snow to
avoid damages due to humidity.
