Before opening or closing the shut-off valve, release the valve spindle seal by approx. of a turn counter-clockwise. After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise.

Page 13: Operating Mode Of The Lockable Service Connections
For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. The filter has to be be renewed depending on the degree of contamina- tion (reduced pressure loss). AQ452523677525en-000201 | 13 © Danfoss | Climate Solutions | 2023.07... -
