24 Start-Up Steps, Basic Maintenance & Growing Tips Start-Up Procedure Basic Maintenance After assembly, complete these steps to check the system before operation: 1. Ensure that the drain elbow of each channel is inserted into the 4" drain tube. 2. Check that the 4" vertical drain tube is inserted through the gasket in the reservoir cover. 3. Verify that the AC2804 in-line valve at the drain end of each 1" pvc manifold is closed. 4. Open each AC2804 valve positioned near the Y-filters. 5. Close the shut-off valves at the end of each Y-filter. 6. Check that each 1/4" micro tube and valve assembly is inserted into the end cap of the GT80 channel. 7. Open all micro valves in the 1/4" micro tubes. 8. Verify that no electrical cords are inside the reservoir. 9. Fill reservoir with water until water pump is submerged. 10. Plug in the air pump to ensure air is flowing through each stone. 11. Plug in the water pump to circulate water throughout the system. 12. Check all fittings and channel end caps for leaks. Repair as needed. 13. Check all 1/4" micro tube and adapter connections to ensure none are leaking. 14. Check drain tube connections and caps for leaks. Seal as needed. 15. Monitor the flow of water through the trays. Adjust frame pitch if needed or level frame if water flows to one side of the channels. Water should flow evenly and consistently throughout all channels. 16. After making the necessary adjustments, the system is ready for production. This system requires regular maintenance and cleaning. The duration between the maintenance and cleaning sessions, however, depends on how and where the system is used and what seeds are grown. The only way to determine a regular maintenance and cleaning schedule is to closely monitor your system once it is fully functioning. A clean system increases production and reduces loss due to mold and other harmful factors. Below are a few suggestions to help maintain and clean the system: Check all fittings to ensure there are no leaks. Repair or replace damaged parts immediately. Seal all leaks when found. For best results, clean and disinfect the channels after each harvest. System is designed so channels can be removed and cleaned. Use a 10:1 mixture (water/bleach) to disinfect the channels when cleaning. Rinse thoroughly to remove the cleaning solution before reseeding the channels. Store and prepare seeds in an area that is separate from the operating system if possible. General Growing Tips Despite the factors that must be addressed before you begin using your system, these general tips will help you get started: Water Quality: Clean water is a must. If you can t drink it, don t use it. If you are not sure about the water quality, have it tested. Water Temperature: Keep the water temperature constant and in the range suitable for the seed or grain you are using. Seed Quality: While it may cost slightly more, good quality, clean seed will save time. You won t have to clean the seed, or worry about foreign objects in the seed. Climate Control: A properly maintained environment is a must. Ensure you have controls in place to automatically control temperature and humidity. Additionally, do not rely solely on automatic equipment; ensure you are physically monitoring the environment daily and make adjustments if needed. Keep the System Clean: Follow the cleaning guidelines presented in this guide Revision date:

25 Filter Cleaning Steps Clean the Filter Screen and Housing Regular cleaning of the filter is recommended to ensure proper flow. Filter should also be cleaned after cleaning the reservoir to remove sediment. When a reduced flow rate is noticed, follow these steps to clean the filter and filter housing. ATTENTION: SYSTEM SHOWN MAY DIFFER FROM ACTUAL SYSTEM. FILTER ASSEMBLY IS THE SAME. STEPS FOR CLEANING THE FILTER ARE THE SAME. Flow 1. Turn off the nutrient pump. 2. Grip the filter housing and the main supply line and unscrew the housing. Do not apply force to the filter or the supply line fittings. Hold these steady when disassembling the filter. 3. Remove the screen from the housing. Using clean water, rinse the housing and the screen. 4. Insert the screen back into the housing, reassemble the filter, and close the valve. 5. Turn on the pump and check the flow from the supply tubes to each bucket. 6. Check filter for leaks. Revision date:
