PLUMBING CONNECTIONS
Plumbing connections
must comply with applicable sanitary, safety and plumbing codes.
Water Requirements
Proper water quality can improve the taste of the food prepared in the steamer, reduce liming in the steam generator and extend equipment life. Local water conditions vary from one location to another. Ask your municipal water supplier for details about your local water supply prior to installation.
Presence of sediment, silica, excess chlorides or other dissolved solids may lead to a recommendation for alternate form(s) of water treatment. Test the water with a TDS meter or the test strip included with the steamer. Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases.
Water Treatment
A local water treatment specialist should be consulted before installation of steam generating equipment.
Supply Pressure | 20 - 60 psig |
Hardness* | less than 3 grains |
Silica | less than 13 ppm |
Total Chlorine | less than 4.0 ppm |
PH range | 7 - 8 |
Undissolved Solids | less than 5 |
| microns |
*17.1 ppm = 1 grain of hardness
If the water supply fails to meet these standards, it will be necessary to install a water conditioner on the generator water feed.
The use of strainers or filters will not remove minerals from the water.
C24GA SERIES GAS CONVECTION STEAMERS
Water Supply Connection
Connect the treated cold water supply line to the 3/8" NPT inlet at the rear of the steamer. Connect the untreated cold water supply line to the 1/8" NPT, also at the rear of the steamer.
Note: Models manufactured after June 2006 may have ¾" hose connections.
A water filter system is recommended for the water supply line going to the treated water inlet of your steamer. Follow the recommendations for use and installation instructions shipped with the water filter. If a water filter is not installed, the steamer or steam generator warranty will be limited.
Filter System
If you decide to not install a scale reducing filter system designed for steam equipment or use another manufacturer’s system other than recommended by Vulcan Hart, please use these guide lines.
•If you are going to delime the unit with a deliming agent recommended for a pressure steam boiler and stainless steel generators and you are on city or treated well water, you still must have a carbon block filter installed and maintained. Carbon block filters remove the chlorine and chloramines disinfectants from the water. Chlorine and chloramines will erode the boiler or steam generator and will result in a vessel failure which is not covered under warranty.
•Water feed lines to the steamer must be flushed before final connection. Particles in the water could build up in the water and steam valves or clog tubing and components that maintain the water level and pressure in the boiler or steam generator. If the water supply is not free of sediment or cloudy after several minutes of flushing, a sediment filter must be installed before use.
