5.4 Stopping the unit
To stop the unit:
Disconnect electric power supply.
Close the Vi on/off valve.
Close Vc valve giving the cooling liquid to the heat exchanger (only KRVS /T units).
Warning : Check that the deceleration of KRVS is uniform and without vibrations
Warning : Close the seal cooling liquid supply only when KRVS returns at the ambient
(<40°C)
5.5 Black-out
In case of black out KRVS is not damaged and not induce any risk of explosion.
Warning : During the blackout it is forbidden to carry out any staff service on KRVS
When electrical supply is restored re-start KRVS following plant and start procedures indicated at par 5.2.
