20. If all functions have performed normally,record the meter readings and secure the lids. 21. If anything fails to function normally,re-test by moving the float(s), float stem,or cartridge handle slower and pausing between functions. 22. If something still fails to function properly,carefully document all observations and immediately seek assistance. 8.3 FAST Unit and Blower Assembly Inspection of the FAST unit is recommended on a semi-annual basis, at least for the first year. The only moving part in the system is the blower unit and it has an alarm feature in the event of failure.However, periodic inspection is important to verify blower performance and to check the filter on the intake. Measurement of sludge and scum levels is recommended at least annually, as discussed in greater detail in a subsequent section of this manual.Additional details regarding the operation and maintenance of the FAST unit are included in the Owner's Manual and the Service Manual,both of which are attached in Appendix D. 8.4 Drainfield Monitoring Ports A monitoring port is located near the terminal end of each trench.The monitoring ports are accessible from the surface through a plastic valve box.The monitoring ports allow access to the soil absorption trenches for liquid depth measurements.Differences between trenches are common in a serial distribution system(e.g.,the top trench is expected to be full before the next trench receives any effluent). Seasonal differences are expected due to the preceding weather patterns. Evaluating the presence and/or depth of ponding within the subsurface soil absorption trenches can be • done with the following steps: 1. Remove the lid to the valve box(protective cover). 2. Remove the capon the PVC monitoringport. 3. Use a tape measure, or other suitable devise, and a flashlight to determine the presence and depth of any water standing in the port(trench). 4. Note the appropriate information on Form 4. 5. Replace the PVC cap and protective cover. 6. Repeat for each monitoring port. 9.0 ANNUAL MONITORING The Annual Inspection and Pump Calibration Checklist(Form 5)is used to record annual monitoring activities. 9.1 Tank Inspections The purpose of the septic tank is to capture and retain settleable and floatable solids from the sewage. Solids are also expected to accumulate in dosing tanks and treatment unit, although at a much slower rate. It is necessary to measure the depth of sludge and scum at least once each year to determine whether it is time to have the tank(s)pumped(solids removed). Tank inspection can be conducted with the following steps: CES-Albany,OR St.Innocent Winery and Tasting Room 0&M Manual Doc:2018240028 St.Innocent Winery OM BTR May 2018 I Page 6
