Operating procedures

Tap Operation

Autoboil is fitted with a two-way safety tap.

The tap assembly has two positions, one is the “cup fill” quick return mode. 
This operation is achieved by having the handle with the curved cam at the 
base of the tap handle facing you. When the handle is released this mode 
allows instant water cutoff.

The second mode is “pot fill”, to use this position rotate the handle 180º 
from the “cup fill” side so a flat face cam is showing at the handle base. This 
operation allows a vessel to be filled without holding your hand where it may 
be affected by steam.
