Vulcan-Hart C24EA3 480V PRO Electrical Specifications, Water Supply Requirements

MODEL C24EA - GENERAL

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 electrical service.

	WATER SUPPLY REQUIREMENTS
! Supply pressure should be						20-60 psig

!In line strainer for supply line (Supplied)

! Total dissolved solids (TDS)*		less than 60 ppm
!	Total alkalinity	less than 20 ppm
!	Silica	less than 13 ppm
!	Chloride	less than 4.0 ppm
!	PH factor	6.5 to 8
!	Undissolved Solids	less than 5 microns

*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.
