5. Pressure in kettle (read pressure gauge on front panel) should reach a maximum of 30 psi
and pressure relief valve should not open. Kettle pressure may rise 2 or 3 psi even after
burners shut down.
6. Relief valve should not open when kettle pressure is 30 psi.
7. If relief valve opens, reduce setting on pressure switch, cool kettle completely by running
cold water through it and repeat steps 3 - 6.
8. If pressure in kettle is below 30 psi increase setting of pressure switch, cool kettle
completely by running cold water through it and repeat steps 3 - 7.

position.

ADDING WATER
It may be necessary to replenish water in the jacket when the low water indicator comes on. Do
so as follows:
1. Unit should be completely cold and off.
2. Lift handle of pressure relief valve to release vacuum in kettle (relief valve is at left rear of
kettle).
3. Remove air vent nut on the elbow located at the rear left of the unit.
4. 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 the water level at the sight glass is half way between the minimum and
maximum levels.
5. When sufficient water has been added, replace and tighten the nut.
6. Vacuum must now be re-established. See following section.
