*The frequency of these maintenance items may vary based on the hardness of water in your area.
A. Add anti-scaling water treatment.
Add the recommended dosage of anti-scaling water treatment into the water tank. Use a TDS
meter to determine the hardness of water in your area. (See “Pre-start Procedure” Step #2 Page 7)

Scale is caused by dissolved mineral in water settling on internal surfaces. Scale build-up can
greatly impact steam vessel longevity and operating efficiency. Adding anti-scaling water
treatment will help prevent scale from forming on the inside wall of the steam vessel and protect
against sensor malfunctions.
Only add water and manufacturer approved anti-scaling solution to the water tank.
