1. Best Practices 10 11 12 13 14 For optimal machine performance the machine should be fed every 4 hours with large feedings If there is a space constraint smaller more frequent feedings are acceptable For optimal micro organisms performance a mixed diet containing protein carbohydrates and some fats should be introduced into the mixing chamber throughout the day Optimal digestion rate occurs with food items that are small in size Large pits should be avoided They will not be digested and will have to be removed from the machine They may also cause damage Corn husks cobs pineapple tops bottoms skins and cores should be avoided These items do not breakdown efficiently and will need to be removed periodically Large additions of baked items should not be introduced at one time This will negatively impact the digestion process Large meat bones should be avoided The will not be digested and will have to be removed from the machine They may also cause damage to the machine Waste will digest most rapidly at room temperature since it will not bring the temperature inside the machine down DO NOT add any cleaning agents chemicals or boiling water to the machine they will kill the microorganisms and the machine will need to be sanitized and restarted to resume operation Water temperature should be 104 Fahrenheit 39 degrees Celsius for optimal machine performance Avoid adding straight fat or oi2. AUTO Parameters shown above do not represent actual values Machine is now running in Auto Mode 10 Page 2 2 Operating in Auto Mode continued 6 There are 4 important parameters displayed in Auto mode Below isa brief explanation of each parameter e Speed 1 The rate of speed at which the paddles rotate inside the Eco Safe Digester The default RPM Revolutions per Minute setting is 6 rpm e Temp 2 The temperature range for optimal performance is 30 degrees Celsius to 39 degrees Celsius e Weight 3 and 4 These displays depict the weight of the food waste in real time The User can monitor or schedule feedings using these values as guidelines The recommended input at one time is a quarter of the machine capacity every 4 hours i e Eco Safe 800 Ib machine can accept 200 Ibs every 4 hrs e Input scheduling is crucial to achieve the machine s optimal capacity e Upon initial startup the machine needs to cycle through a warming up period During this period the machine will not start until the shell temperature reaches 15 degrees Celsius e When the hatch is open in Auto Mode the machine will temporarily stop running as a safety precaution When the hatch recloses operation will resume automatically e Periodically inspect and clean any debris which may inhibit proper door sensor functioning The sensors are located on the left and right side of the hatch opening 11 Page 2 3 Optimal Input Schedules

6. Feeding the machine every 4 hours is the optimal feeding interval for all Eco Safe models A quarter of the machines maximum capacity is the optimal input at each 4 hour interval A smaller input at more frequent intervals is acceptable However the above feeding schedule is what is recommended for optimum performance The following procedure explains how to introduce food waste in to the machine Step 1 Observe the position of the Light Tower on the top left side of the machine If the light is green go directly to Step 2 If the light is yellow monitor the current weight to ensure overfeeding does not occur Overfeeding will cause the machine to temporarily shut down If the light is red the machine is in Stop mode Stop mode indicates that the machine has been overloaded This safety function not only protects the drive modules of the system but also lets the User maintain optimal conditions To correct a system overload food must be removed from the machine until the light turns back to yellow Then click the Error Reset button on the main work screen The machine will then restart automatically Step 2 A green light means the machine is ready for its next feeding Please refer to 2 3 for recommended feeding intervals Step 3 Keep the top of the machine clear of all debris It will add to the total weight of the system causing a reduction of input capacity and less consumption of the waste 12 Page 2 4 Total Monitoring
