PLUMBING CONNECTIONS
WARNING: 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 contitions vary from one location to another. Ask your municipal water supplier for details about your local water supply prior to installation.
WATER REQUIREMENTS
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
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 the test strip included with the steamer. Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases. A local water treatment specialist should be consulted before installation of steam generating equipment.
Water Supply 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 may be limited.
Filtered Water Connection — 1/4" NPT. Used for boiler feed water.
Unfiltered Water Connection — 1/4" NPT. Used as cold water condenser on boiler
Drain
CAUTION: In order to avoid any back pressure in the steamers, do not connect solidly to any drain connection.
The drain must be the open air gap type. Provide a suitable floor sink with a minimum depth of 12" (30 cm). The floor sink is NOT to be located directly under the steamer. Local codes require that the maximum temperature of drain water must be no greater than 140°F (60°C). Refer to Fig. 4 on page 9. The drain pipe should be either iron or copper. DO NOT use PVC pipe; PVC pipe may lose its rigidity or glue may fail.
