Your MEGA-PURE 12A Water Still is protected against overheating by
two thermal switches, located in the black "V" shaped bracket at the left
hand side of the boiler, that will shut off both the water supply and power
to the heaters when activated. Always allow the unit to cool completely (5
- 15 minutes) before resuming operation. Cool water on hot glass could
cause boiler damage. When unit has cooled, press "WATER" and
OPERATE" switches to restore normal operation. Check boiler
occasionally for proper water level.
