The manual opener of EVRA/EVRAT 10, 15 and 20 is intended to be activated only during
initial pressure testing of the refrigeration system.

After pressure testing or service-related manual forced opening of the manual opener
the spindle must be turned fully back to back-seated position to avoid any packing
gland leakage.

Furthermore it is essential that the sealing cap is properly reinstalled. This will eliminate
any risk of leakage from the manual opener.
