Warning
Never switch on
power to the
coil when the
coil is dismounted
from the valve.
Otherwise the coil
may be damaged
and there is risk of
injuries and burns.
The manual opener of EVRS 3-20 and EVRST 10-20 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.
