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
commissioning 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 that may
affect or prevent the funtion of the safety valve.
Carry out maintenance and inspectionw with approp-
riate 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 never falls below the ambient
temperature. 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
defined during commissioning.
An annual review is recommended. The following compon-
ents must be checked for proper function (if installed):
• solar collectors
• solar circle
• heat transfer fluid
• solar storage
• solar regulator incl. circulation pump
• supplementary heating system
Unscheduled maintenance
Depending on the location of the installation, environmental
influences may cause soiling on the collector glass (dust,
pollen etc.). Clean the glass, if necessary, exclusively with
clear water to ensure optimal light transmission.
If it is necessary to free the system from snow or ice, use
only non-metal cleaning equipment, such as brooms, with
due care.
Walk on roof areas only 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.
