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).
