Shutting down the system
For overnight or short time periods:
♦
Because the ZIMMER uses only a small amount of electricity
(e.g. approximately 300 - 600 watts in 1 PH operation for Z50)
when there is no load, it is suitable to leave the power engaged
even during periods of non-use. If desired, close the vaporizer
outlet isolation valve when the vaporizer is not being used.
For extended periods:
♦
Close the vaporizer outlet isolation valve.
♦
Open the disconnect switch to power off the vaporizer.
♦
Close the inlet valve or tank valve(s) only after the vaporizer has
expanded the remaining gas and pushed it back toward the tank
(approximately 5 minutes). Trapped liquid can expand when
heated causing damage or possible rupture to pipes and
components. Always install hydrostatic relief valves between
isolation valves.
