A S S E M B LY
Collector mounted according to installation instructions
Solar circuit integrated in the potential equalisation
Discharge line with collecting container (container for antifreeze)
mounted for the pressure relief valve of the solar circuit
All thread connections checked and solar circuit pressure tested
(with air or solar fluid); installation test pressure:
Pipes completely insulated with solar insulation
C O M M I S S I O N I N G
Solar circuit flushed (do not use water) and vented several times
(in case of several heat exchangers: actuate the valve(s)!)
Solar circuit filled with COSMO heat transfer fluid WTF
System pressure of 1.5 bars plus static height (0.1 bars/m) refilled
Initial pressure adapted at the expansion tank before filling
(0.2 bar below system pressure, cold)
System pressure: bars at
Caps screwed onto fill and drain valves
F U N C T I O N
Solar controller set according to system hydraulics (COSMO UNO)
or set and programmed (COSMO Multi2);
green function light is ON
Flow rate with manually switched pump
set at the controller: ..................................... l/min
All temperature sensors display realistic values
During intense solar radiation, the temperature difference
between the collector and the storage tank should be of 10-14 °C
If necessary, proper function of the post-heating of the storage tank(s)
checked; nominal temperature: ......... °C
Proper function of all connected electrically driven valves and fittings
(pumps, valves, etc.) checked by operating the relays
in the controller manually

Basic functions and operation of the solar controller
Function and operation of the post-heating
Operation of the vent valve for permanent venting of the solar station
Maintenance interval (heat transfer fluid, anode, etc.)
Hand over of the installation documents
(possibly special switching scheme)
