The EVR 2 – EVR 22 with solder connections and without manual stem can be applied on systems with R32, R152A, R290, R452B, R454B, R600,
R600a, R1234yf, and R1234ze as the working uid. For countries where safety standards are not an indispensable part of the safety system
Danfoss recommend the installer to get a third party approval of the system containing ammable refrigerant. Note, please follow specic
selection criteria stated in the datasheet for these particular refrigerants.

Caution!
For EVR 2 – EVR 3, and EVR 10 – EVR 22, a screwdriver might be needed
for removal of the gasket. Be careful not to scratch the gasket surface.

Manual operation for pressure testing and service related operation:
Only use the manual stem operation of the EVR NC valve during initial pressure testing of the refrigeration system or during service related
manual operation. Remove the protective cap and rotate the manual stem clockwise approx. 6 cycles from fully closed to fully open
position. After the manual operation is completed, ensure to rotate the manual stem counter-clockwise back to fully closed position and
re-mount the protective cap before connecting the valve to automatic operation. MOPD for the manual operation function is 5 bar.
Alternatively, all EVR NC and NO valves can be manually operated by removing the coil and force the valve open or closed by using a
solenoid valve tester (permanent magnet).
