Commissioning (for engineers only)

Logamatic SC40 - Technical specifications are subject to change without prior notice.

Commissioning (for engineers only)

Follow the instructions in the technical documentation for the solar pumping station, the collec-
tors and the solar storage cylinder when commissioning the solar thermal system.

Only put the solar thermal system into operation when all pumps and valves are in proper working
order.

Perform the following steps in connection with the solar pumping station:

Check the system is clear of air.

Check and adjust the flow rate.

Enter the controller settings in the commissioning and maintenance report (

installation and

operating instructions for the solar pumping station).

Warning:

risk of damage to pump if run dry.

Make sure that the solar thermal circuit is filled with solar fluid (

installation and

maintenance instructions for solar pumping station).

Warning:

commissioning when there is frozen water or vaporisation in the solar ther-

mal system can damage the system.

Shield the collectors from direct sunlight during commissioning.

Do not commission the solar thermal system at sub-zero temperatures.

Warning:

setting the wrong operating mode can damage the system.

In order to prevent undesirable starting of the pump when the power supply is con-
nected, the controller is factory-set to

Always off

mode.

For normal operation, set the controller to

Auto
