3.
Lift handle of pressure relief valve to release vacuum in kettle. (Relief valve is at left rear of
kettle.)
4.
Remove air vent nut on the elbow located at the rear left of the unit.
5.
Using pure distilled water only, pour the water into the opening. (A funnel will be helpful.)
Water will enter the kettle slowly, as air must escape through the same hole. Water should
be added until water level at the sight glass is half way between the minimum and
maximum levels.
6.
When sufficient water has been added, replace and tighten the nut. Be sure to seal
threads with a pipe joint compound suitable for steam at 50 psi.

Vacuum must be re-established. (See Re-establishing Vacuum.)
