VL SERIES STEAMERS - GENERAL

This causes several problems:

1.Reduce the heat transfer efficiency of the heating system.

2.Cause premature failure of Electric 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 boiler with soft water. Vulcan recommends the water contain less than 60ppm of “total dissolved solids” (TDS) and have a PH factor between 7 to 8. These water properties can be achieved by using a properly maintained water softener.

Other chemical properties in water supplies can also affect good steam generation and vary from within each state and locality.

The water level probes in the boiler use ions in the water to detect the water level. Do not use fully demineralized or de-ionized water since it is "non conductive" and the water level can not be detected.

NOTE: The use of strainers, or filters will not remove minerals from the water.

Vulcan recommends that a local water treatment specialist be consulted before the installation of any steam generating equipment.

Steamers that operate over a long period of time without the benefit of a water softener, which have developed a heavy scale build up, should be cleaned before using a water softener.

TOOLS

Standard

Standard set of hand tools.

Volt-Ohm-Meter (VOM) with AC current tester.

(Any quality VOM with a sensitivity of at least 20,000 ohms per volt can be used)

Gas leak checking equipment.

Gas pressure manometer

Temperature meter and thermocouple.

Special

CLR Treatment Kit - Used to remove Calcium/Lime/Rust from a boiler (Contact

￿Vulcan Authorized Service Centers ).

Adaptor to test thermocouple closed circuit voltages (DC) on gas models with manual ignition (purchase locally).

NOTE: Adaptors vary between manufacturers. An example of one adaptor type is pictured below.

SPECIFICATIONS

Water Supply

Supply pressure should be	20-80 psig
In line strainer for supply line	(Not Supplied)
Supply connection	cold
Total dissolved solids (TDS)*	less than 60 ppm
Total alkalinity	less than 20 ppm
Silica	less than 13 ppm
Chloride	less than 30 ppm
PH factor	7 to 8

(*17.1 ppm = 1 grain of hardness)

Steam Supply

Dry steam must be provided to the steamer for suitable use. If the steam is heavy with condensate, a Ball Float Trap must be used in the line and plumbed in before the pressure reducing valve. To ensure rapid heat up of heavy cold loads, the steam supply line must be sized to maintain pressure as outlined below.

	DIRECT STEAM	REGENERATED
