6  Operation

6.1  Start-up procedure

The following procedure is to be respected at every system start-up.

•  Close the liquid-in valve and open the liquid-out valve.

•  Open unit vent plug and then fill the unit while venting.

•  When all air has been discharged from the liquid circuit, close unit vent plug.

•  Start liquid pump.

•  Open system inlet valve slowly until the appropriate liquid flow is reached.

•  Verify there are no leaks in the liquid circuit and connections.

•  Switch on fan power supply.

•  Start the fans and verify fan direction.

•  After some operating time, check the absence of air in the liquid circuit (vent if needed) and 

verify that current absorbtion does not exceed the value as given in the technical specifications.

6.2  Shutdown

If the unit requires emptying for maintenance, system shutdown or dismounting, proceed as follows:

•  Stop liquid supply and switch off electrical power supply. 

•  Make sure neither liquid nor power supply can be resumed accidentally or unexpectedly.

•  Close liquid-in and liquid out valves.

•  Install a proper hose at the drain valves. Open venting and draining valves. Attention: fluid may 

be hot.

•  Make sure all drained liquid will be collected in a suitable vessel.

•  Compressed air helps to drain in less time. Compressed air shall be oil free.
