The equi-potential stud ¥ is located on the top of the vaporizer. When
connected, it minimizes any electrical potential difference between the
vaporizer casing and the anesthesia system.

The sump contains the agent and includes the agent filling port, the
drain, the heaters and the agent Jevel sensor.
The sump has a total nominal capacity of 390 milliliters (ml) which con-
sists of a nominal 330 ml indicated volume and a nominal 60 ml
reserve.
Two 100W heater elements, located in the base of the sump, heat the
agent to a nominal 39 °C (102 °F) to generate the working pressure.
Two 100W heater elements located in the upper part of the vaporizer
help prevent condensation of the anesthetic agent in the vaporizer.
The current supplied to power the heaters alternates between the two
heaters in the sump and the two heaters in the upper part of the vapor-
izer. This minimizes the current requirement.
While it is connected to the electrical supply, the casing of the vapor-
izer is normally warm to the touch.
Internal electro/mechanical sensors monitor and maintain the fresh
gas/agent vapor pressure balance and the agent volume.
The internal sensors monitor and display operational status and acti-
vate the appropriate alarm indication.
