The greater the length of piping and number of valves and elbows, the greater will be the pressure losses. Consider a pressure drop of 1 (one) psi for each straight length of pipe equivalent to 120 diameters of that pipe. Thus, a 1" pipe having a straight length of 120" (10 feet) is equivalent to 120 diameters of that pipe and will have a pressure loss of 1 psi through that pipe. Example: 9 p.s.i. AvailablePressure10 p.s.i. SupplyPressure120 Diameters of 1” pipeEquivalent to 120” (10 ft) Note, in 3/4" pipe size, that a Standard 90. Elbow and Angle Valve and a Globe Valve are equivalent to 1.8 feet, 10 feet and 18 feet respectively of straight pipe. Similarly, in a 1" pipe size, a standard 90. Elbow and Angle Valve and a Globe Valve are equivalent to 2.2 feet, 12 feet and 23 feet respectively of straight pipe. Example: 20’ 32 PSI3’ 90° ELBOW17’10’ GLOBE VALVE1” PIPE40 PSISUPPLY Total of above = 20 + 2.2 + 3 + 2.2 + 17 + 23 + 10 + 2.2 = 79.6 feet. Since each 10 feet is equivalent to 1 psi pressure loss, 79.6 feet is equivalent to approximately 32 psi from an original Boiler supply of 40 psi. It is suggested that, wherever possible, the steam supply line to the appliance is a separate line from the steam source. If the appliance must be supplied from a line supplying other appliances, the pipe sizes and pressure will have to be verified. Further, during idle periods, when the steam in the supply line is not in use, water will form from condensed steam in the supply line. It is advisable to prevent water pockets from forming in the steam line and impeding the steam flow when it is required. Therefore, the steam supply line should be installed level or run slightly downwards towards the appliance. Install a Ball Float Trap near the appliance to drain out water (condensed steam) from the line to assure clean dry steam to the appliance. INLETTO HEATEXCHANGERTO DRAIN123 3.0 OPERATING INSTRUCTIONS CAUTION: Live steam and accumulated hot water in the compartment may be released when the door is opened START-UP Start-up procedures for the steamer must be completed once daily prior to operation. 1. Turn on the water and steam supply to the appliance. 2. Open the cabinet door and turn the power switch to ON. A pilot light comes on indicating the appliance is ready to begin operation. With the READY pilot on, preheat each steamer compartment for one minute when the steamer is to be fist used for the day or whenever the compartment is cold. OPERATION 1. With cooking compartment preheated and ready pilot light on, place pans of food to be cooked into compartment and shut door. 2. Set timer to cooking time desired. Cooking cycle may be interrupted at any time by opening door and resumed again by closing door. 3. When buzzer sounds, it indicates the end of the cooking cycle and that no more steam is entering the compartment. Cooking pilot light will go off and ready pilot light will come on. Buzzer must be shut off by turning the timer to its off position. CAUTION: An obstructed drain can cause personal injury or property damage. Frequently check that the compartment drain and plumbing is free of all obstructions. Never place food containers, food or food portion bags in the cooking compartment in such a way that the compartment drain becomes obstructed. SHUT DOWN 1. To shut down cooking compartment, set timers to their OFF position and leave doors slightly open. 2. At the end of the day, open the door of the cabinet base and turn off power switch. Turn off external steam supply valve. Each compartment is equipped with a removable drain screen. Frequently check the drain screen for accumulation of food particles. Should food particles accumulate against, or clog the drain screen, remove it, clean it thoroughly and then replace it in its original position. 4.0 PERIODIC MAINTENANCE Never spray water into electric controls. CLEANING 1. Keep exposed cleanable areas of unit clean at all times. 2. Thoroughly wash...
