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 conditions 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 combi oven. 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.

A water filter system is recommended for the water supply line going to the treated water inlet of your oven. Follow the recommendations for use and installation instructions shipped with the water filter. If a water filter is not installed, the oven warranty may be limited.
Connect treated potable water (hot or cold) to the inlet labeled for treated water to supply the steam generator tank and humidifier. Untreated water contains scale producing minerals which, if supplied to the steam generator, can precipitate onto the surfaces in the steam generator tank. Due to the temperatures in the tank, the minerals can bake onto the surfaces and components. This can result in early component failure and reduced product life. Sensors in the steam generator tank use ions in the water to detect the water level. Do not use distilled (fully demineralized or
Connect untreated potable water (must be cold) to the inlet labeled for untreated water to supply the condenser which cools the drain water.
