by a qualified service technician. Generator descaling instructions are provided on a separate data sheet Failure to periodically remove scale from the inside of the generator will result in greatly reduced generator Bie. 4) Every steam generator is equipped with at least one corrosion resistor to reduce generator shell corrosion and scaling. This corrosion resistor is sacrificial and must be replaced at regular intervals just before it is entirely consumed. In areas where the water is very hard, the feedwater must also be treated to remove the harmful mineral content. Refer to separate data sheets for corrosion resistor servicing instructions, feedwatertreatment information, and hand hole plate servicing instructions. 5) Cheek the safety valve once a week while steam generator is pressurized. Test by pulling safety valve extension wire. Valve must open freely and snap dosed when released. If it does not or if it drips constantly, a new safety valve is needed. 6) If the steam generator!* to be left idle fortftree months or more, it should be drained and dried out and the hand hole plate left off. 7) Water level in the sight gauge normally should be about 2/3 fuIL This level is maintained automatically. Refer to separate data sheet for either mechanical or water fill servicing instructions. 8) If gas fired, the lighting instructions are on the AGA rating plate. Pilot burner is lit through hole in panel at bottom of steam generator. This panel should never be left off as this will damage the controls. Burners will not light without water in the steam generator. 1090 CLEVELAND RANGE CO., 1333 EAST 179th ST., CLEVELAND, OHIO 44110 Manufacturer reserves ngfct of design improvement or modification, as warrantee. LÎTHO IN U.S.A. Oaa Shaat 260-SA WATER QUALITY REQUIREMENTS — STEAM GENERATOR PROTECTION AND MAINTENANCE A steam generator, or boiler, unlike otner types of water-using kitchen equipment distills the water in order to таке steam. Nearly all feed water sources contain dissolved minerals in varying degrees of concentration. As this water is boiled. pure steam rises from its surface, upward to the cooking compartments), leaving miner-sis behind, that can become harmful to the steam generator. if minerals are allowed to accumulate inside the steam generator, they «nil solidify as a scale. Then, malfunctioning will occur, and serious equipment damage may result The use of good quality generator feed wateristhe responsibility of the owner/user. The use of poor quality feed water could void equipment warranties. The minimum treatment required in most areas is water softening, although local water conditions may require more intensive pretreatment than simply a water softener. Scale problems occur when feed water is high in hardness. total dissolved solids, silica, and alkalinity. Water softening will only reduce the water's hardness, which is the presence of dissolved salts of magnesium and cai-cium. Water softening will not affect the multitude of other minerals found in most water supplies. Because generator scale is the result of the precipitation of many minerals, the best property to control, for generatorfeed water, is total dissolved solids, not just hardness. The recommended minimum water quality standards, whether untreated or pre-treated. based upon 10 hours of use per day, and a Dafly Blowdown, are as follows: TOTAL OSSOLVEDSOUBS Man fcOc total AuuuNrrr мап xfp SlUCA памп 131 PH FACTOR ГПИП ZS Consult a local water treatment specialist for an on-the-premises water analysis and for recommendations concerning steam generator teed water treatment (if required). in orderto remove or reduce harmful concentrations of minerals. tf the recommended water quality requirements are met without supplemental treatment or if treatment is applied, resulting m feed water quality meeting the prescribed standards, the steam generator will need to be blown down only once each day. In addition, the inside of the generator requires an inspection (for excessive lime accumulation and consumed corrosion resistors) only once every six months. Replace the corrosion resis-tor(s) and chemically descale the generator as required. tf a pre-treatment unit cannot be installed, and the recommended water quality requirements are not met the following procedures should be followed, in orderto achieve maximum steam generator service life. The steam generator should be blown down after each 6 hours of use. Have the seam generator inspected, inside and outside, by a qualified technician every 3 months. If the corrosion resistor(s) is totally, or neatly consumed, replace it if the inside of the generator is heaviiy coated with scale, have it chemically descaled by a qualified service technician.
