This degree of hardness and pH can easily be obtained with the use of a properly maintained water softener. Water supplies vary from one location to another. A local water treatment specialist should be consulted before installing any steam generating equipment. Untreated water contains scale producing minerals which can precipitate onto the surfaces in the boiler. Due to the temperatures in the boiler, the minerals can bake onto the surfaces and components. This can result in early component failure and reduced product life. Mineral scale on components causes several problems: 1. The surfaces of the heating devices become coated with scale, reducing the heat transfer efficiency. This can produce hot spots on the heating elements and result in premature failure. 2. The water level probes become coated with scale. Scale will bridge across the probe insulator from the metal extension which senses the water level in the boiler shell. Once this scale becomes wet, the water level control is unable to maintain the proper water level in the boiler. This situation may cause an electric heating element to fail if the element is not adequately covered by water. Strainers and filters will NOT remove minerals from the water. Refer to REMOVAL OF LIME SCALE DEPOSITS, page 12. VENT HOOD Some local codes may require the steamer to be located under an exhaust hood. Information on the construction and installation of ventilating hoods may be obtained from Vapor Removal from Cooking Equipment, NFPA standard No. 96 (latest edition). 20 (500) MIN. BY CUSTOMER 2 (51) TESTING PROCEDURE WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR SERVICING THE STEAMER. THE COOKING COMPARTMENT CONTAINS LIVE STEAM. STAY CLEAR WHILE OPENING THE DOOR. Once the steamer is installed and all mechanical connections have been made, thoroughly test the steamer before operation. 1. Check that proper water, drain, and electrical connections have been made. 2. Open water valve. Turn main power switch ON. After approximately 15 minutes, the READY light should come on, indicating that the water temperature is 205°F. 3. When the READY light comes on, turn the dial timer to 5 minutes. With door open, observe that no steam is entering the compartment and the COOKING light is not lit. 4. Close compartment door. The COOKING light is lit and steam should be heard entering the compartment. 5. Check drain line to ensure that water from the cold water condenser is flowing through the drain line. 6. Open compartment door and observe that steam supply to the chamber is cut off. The READY light should come on; the COOKING light goes off. 7. Close compartment door and let cooking cycle finish. When timer returns to 0, a buzzer will sound signalling the end of the cooking cycle. To silence the buzzer, turn the dial timer to OFF. 8. To turn the steamer off, turn the main power switch OFF — the steam generator will drain. Leave the door open to allow the inside to dry out. OPERATI...
