SPECIFICATIONS
NOTE: All C24EA steamers, with exception of 480V steamers, are shipped pre-wired for 208/60/3 operation.
Steamer heating element wiring connection change is required if connecting to 208/60/1, 240/60/1 or 240/60/3

*17.1 ppm = 1 grain of hardness
Water hardness below 4 grains/gal requires water treatment to reduce
potential corrosion. Hardness above 6 grains/gal should be treated by
water conditioner, water softener or in-line treatment.
Water Conditioning
It is recommended that a local water treatment specialist be consulted before the installation of any steam
generating equipment.
Furnishing the steam generator with properly conditioned water to reduce scale formation is important. Scale
formation will reduce steam output, cause premature component failure and shorten equipment life. Most water
supplies contain scale producing minerals such as calcium and magnesium. As steam is generated, the minerals
remain and dissolve into the remaining water. As the concentration of these minerals increases past a certain
point, they precipitate from the water and coat the inside of the tank, heating elements, thermostat bulbs and water
level probes. Because of the high temperature of these surfaces, the precipitated minerals bake onto them and
become very difficult to remove.
This phenomenon causes several problems:
1.
Reduces the heat transfer efficiency of the heaters.
2.
Causes premature failure of the heaters.
3.
Water level probes will give false readings.
4.
Thermostat bulbs will sense temperature incorrectly.
These problems are common to any manufacturer's steamer regardless of design, but they can all be prevented
by furnishing the steam generator tank with properly conditioned water. Vulcan recommends the water contain
less than 60ppm of total dissolved solids (TDS) and have a PH factor between 6.5 to 8.
