Overview of Manual
The manual is organized to cover safety precautions and warnings, an overview of the AMERICAN DRIP SYSTEM components, and the owner's responsibility. A startup log and limited warranty are in the back of this manual.

Safety Precautions and Warnings
The owner or operator of the AMERICAN DRIP SYSTEM should take precautions consistent with operators working with sewage and electricity when working with, or around any of the system components.

Electrical Hazards
The AMERICAN DRIP SYSTEM incorporates pump(s), float switches, relays and many electrical components that use 230 volts, 120 volts or 24 volts AC. Improper use of equipment can cause an electrical shock and may lead to serious injury or death.

Sewage Hazards
Proper attention should be given to cleanup when working in and around the septic and pump tanks and wastewater handling equipment to insure that disease causing bacteria are not transmitted to persons or contact surfaces. The septic and pump tanks can allow for a toxic buildup of poisonous gasses that can lead to serious injury or death if inhaled.

Heavy Lifting Hazards
The owner and/or operator should exercise proper caution when lifting heavy system components, such as pump tank lids. Improper lifting of heavy components can lead to loss of limb and/or mobility.

Overview of the American DRIP SYSTEM
The AMERICAN DRIP SYSTEM is a unique fluid handling system for dispersal of septic effluent wastewater in soil systems. The system incorporates filtration, time and level controlled application, and ultra low rate drip distribution. In conditions where aerobic dispersal, such as "Low Pressure Distribution", of septic effluent is required or where land application with the use of conventional soil absorption fields are not acceptable, this system offers a unique method for subsurface distribution of the waste water effluent.

The AMERICAN DRIP SYSTEM will accommodate virtually any type of pretreatment process, whether septic tank (anaerobic), aerobic, lagoon, or any type of treatment facility. Only primary treatment (the removal of large settleable solids) of sewage is necessary for the operation of the system. Local soil and site conditions may require additional treatment for excessive organics, oil and grease or other contaminants.

Since the installation of the field distribution lines causes very little soil disturbance and effluent discharge volume from each emitter hole is insignificant, the installation of the system has very little site impact even in established lawns or park areas. After installation there are virtually no visible indications that the installation site is being used for disposal purposes. This system is especially suited for landscaped or wooded areas near buildings, trailer parks, apartment complexes or residential subdivisions.

The AMERICAN DRIP SYSTEM is operated via a "state of the art" controller which is activated by level sensing devices (standard mechanical differential float switch) located in a dosing tank downstream from the pretreatment process or processes (typically a septic tank). When activated by the rising level of effluent in the dosing tank, the controller will enable the disposal cycle, and as dictated by the time clock, pump the effluent through a 115 micron disc filter and then to final drip dispersal.

The pump control panel is equipped with four float switches to control the timed doses to be discharged. The four float switches, "Redundant Off", "Standard Dose Enable", Peak Dose Enable", and "High Level" function as follows:

• Redundant Off - The water level must be high enough to overcome the "Redundant Off" (first & bottom) float in order for the pump to be permitted to run.
• Standard Dose Enable - When the water level rises high enough to overcome the "Standard Dose Enable" (second) float and the time clock has timed out the preset time delay (rest between dosing cycles for two zone designs) the pump will activate and the lead zone is dosed. The pump will continue to run for the length of time as adjusted on the pump run timer and then shut off. The pump will remain off until the internal time clock again times out the preset time delay after which the pump will activate (as long as the "Standard Dose Enable" float is still up) and will run until the pump run timer finishes timing out. This process will repeat until the water level drops below the "Standard Dose Enable" float and the pump run timer has timed out.
• Peak Dose Enable - The control system will be equipped with a "Peak Dose Enable" circuit to manage peak flows and excess water use. If the rising water level activates the "Peak Dose Enable" (third) float, the "Pump - Off - Pump & Alarm" switch is set to "Pump", and the preset time delay has been exceeded ("Peak Dose Enable" rest between cycles), the lead zone will be dosed. When the "Peak Dose Enable" circuit has been deactivated the normal pumping cycle will resume. If the rising water level activates the "Peak Dose Enable" (third) float, the "Pump - Off - Pump & Alarm" switch is set to "Pump & Alarm", and the preset time delay has been exceed ("Peak Dose Enable" rest between cycles), the lead zone will be dosed and the "Peak Dose Enable" alarm will be activated. The audio portion of the alarm may be silenced by pressing the Test-Normal-Silence switch to the silence position. When the "Peak Dose Enable" float has returned to the down position the alarm will be deactivated and the normal pumping cycle will resume.
• High Level - If the water level rises enough to overcome the "High Level" (fourth) float, the audio/visual alarm will activate. The audio portion of the alarm may be silenced by pressing the Test-Normal-Silence switch (located on the outside of the control panel) to the silence position. The alarm circuit will latch until manually reset after the "High Level" float returns to its normal (down) position. The alarm circuit is manually reset by switching the High Level Reset/Off-Normal switch (located inside the control panel on the inner door) to the Reset position then back to normal.

Drip Tubing

The drip field supply line conveys the effluent to the drip absorption zone that is being dosed where it is discharged below the soil surface through a patented chemical-resisting pressure compensating self cleaning "drip" poly-tubing emitter. The emitters or "drippers" are located every two feet in the tubing and emit 0.65 gallons per hour per emitter. The dripper lines are automatically scoured (forward flushed) every 50 dosing cycles. This function is activated by the controller which opens the field flush valve, thus allowing the flushed effluent to be returned to the pretreatment tank. The duration of this cycle is approximately three minutes. The flushing cycle produces a high velocity cleansing/scouring action by the effluent along the inside walls of the dripper tubing, P.V.C. manifolds and emitters.

The construction of the "RAM" drip tubing is unique in that the internal diaphragm and labyrinth provide for an exact amount of effluent to be discharged from each of its emitters which are spaced at two foot intervals along the entire length of the RAM drip tubing. Each emitter maintains a constant flow over pressure ranges of 7 up to 70 psi. Because the effluent is distributed at an ultra low rate, large quantities of effluent may be economically distributed over large areas during controlled periods of time without saturating the surrounding soil.

Air Release Valves

The drip field return line conveys the effluent from the drip absorption zone ( used to "flush" or clean the tubing ) back to the pretreatment device. Each zone will have an air release valve housed in a small valve box at the highest point of the return manifold pipe in each zone. The valve will close when the water pressure arrives at the valve during each dose. The air release valve allows air to reenter the tubing after each dose to allow the tubing to drain. This also prevents the uphill tubing from draining water into the downhill tubing and overloading downhill tubing.

In the event of damage to the air release valve, effluent may leak from the system. This condition should be fixed immediately by replacing damaged parts. Air release valves should not be covered with soil or other material and should always be accessible to the service personnel.

Owner's Responsibility

Preventative Maintenance

The drip field area should receive only the most passive type yard uses. No use is recommended when conditions are wet. Under no conditions are any autos or heavy machinery to be allowed on the site.

In order to prevent erosion, the site should be established and maintained as a healthy lawn, or if wooded, mulched and stabilized. Erosion of the site and the adjacent areas should be controlled and eliminated. Surface waters should be diverted away from all components.

Scheduled Inspections

Within a month of operation the owner should contact the installer to have the system inspected for proper startup. After three months of operation the drip field should be walked and the system inspected. Symptoms to look for on the field walk inspection are patches of wetness. If symptoms are identified, notify your service provider immediately. The drip field should be walked & inspected at least annually.

The septic tank and pump chambers should be inspected at least once a year by a trained professional service provider, your American Dealer. The septic tank should be pumped when the sludge level reaches 25% or approximately 12 inches, or when the scum layer on top is excessive. The flow meter reading in the hydraulic unit should be recorded with the date on a quarterly basis.

Alarms - Notifying Service Provider of alarm events

The system controller is equipped with an audio/visual alarm to alarm high water level conditions. The high level alarm may be silenced by pressing the "silence" button on the side of the control. Since a high water level condition can be caused by pump failure, excessive infiltration, or an unusually large peak water use, the owner should call the service provider to determine the cause of the alarm prior to requesting service.

If at any time there are any indications of failure, such as the flow meter not moving during a dose or wetness in the area of the drip field, notify your service provider immediately.

Monitor & Regulate waste input to septic tanks

Since all processes in this sewage disposal system use biological activity to treat the wastewater, only typical biodegradable household wastes are to be disposed of in drains leading to the septic tank. Never dispose of pesticides, oil or grease based products, or non-fecal solids (especially feminine hygiene products) into the system. Minimize disposal of high strength over-the-counter type products such as bleach, and don't use colored toilet tissue.

• Controller

The "state of the art" controller is enclosed in an outdoor electrical control box located near and connected to the hydraulic unit. The control panel uses 230 volt, 1 phase power (unless otherwise noted) and 120V and 24V AC inputs and relay outputs for automatic operation of the AMERICAN SEPTIC DRIP. When in the "Hand" or "Off" position, the manual switches (Hand-Off-Auto) on the door of the control panel completely bypass the microprocessor. The "Hand" position will allow manual operation of the entire system in the event of a microprocessor failure.
NOTE: THE OWNER ASSUMES FULL RESPONSIBILITY FOR CONDITIONS OR MALFUNCTIONS DUE TO MANUAL OPERATION OF THE SYSTEM BY ANYONE OTHER THAN A QUALIFIED SERVICE REPRESENTATIVE. LEAVING THE PUMP CONTROL IN THE "HAND" POSITION WILL FORCE THE PUMP TO RUN CONTINUOUSLY AND MAY RESULT IN PUMP FAILURE.

Hydraulic Unit

The submersible pump delivers unfiltered effluent to each filter. The filter backflushing schedule is triggered at the beginning of each dose cycle. One filter valve closes, thus blocking the flow of unfiltered effluent to that filter. After a short delay, the other flushing valves open, thereby backflushing the unused filter. The accumulated impurities discharge back into the pretreatment unit. The closing and opening procedure of the filter and back flush valves causes a change of flow within the unit to provide filtered water from two filters to backflush the other filter. The backflush procedure lasts approximately fifteen seconds then the back flushing valve closes. Only after the one filter has completed its backflushing cycle, will the next filter begin its cycle of backflushing in the same manner as the previous filter. Effluent will then be pumped through clean disc filters, then through the flow meter and finally through the outlet manifold to the drip field supply line. During extended dose times the disc filters are re-backwashed to assure optimum operation.

Startup Procedures - AMERICAN SEPTIC DRIP

This procedure outlines the startup procedures for the drip dispersal field tubing system. The process includes flushing dirt, pipe shavings and other possible constuction debris out of the tubing and checking dosing rates in a three step process. First, flush through air release valves, second flush through normal flushing process (while checking flow rate), and finally checking final dose flow rate.

I. System Flushing Air Release Valves Off

1. Be sure pump chamber is full of clean water. Check lights on controller for float activation. The "Off" float and "Standard Enable" float should be in the up position before starting field flush. Continue to fill tank to "alarm" float. It should take one days flow of clean water to flush tubing.
2. Place all toggle switches on the inner door in the off position.
3. Remove air release valves, attach piece of 1/2" black flex PVC to 1/2" white PVC with dry coupling (do not glue) and place end to direct discharge away from excavation.
4. Switch pump to "Hand" position. Pump should dead head with no flow meter movement.
5. Place disc filter backwash to filter #1 position. Note blue valve opening. Backwash for 15 seconds,Place disc filter backwash switch to the "Auto" position.
6. Place disc filter backwash to filter #2 position. Note blue valve opening. Backwash for 15 seconds, Place disc filter backwash switch to the "Auto" position.
7. Place disc filter backwash to filter #3 position. Note blue valve opening. Backwash for 15 seconds, Place disc filter backwash switch to the "Auto" position.
8. Turn zone #1 and "Zone Master" to "Hand" position to manual flush. After water starts discharging from flex PVC, flush for three (3) minutes or until no debris (dirt, PVC) is noted, whichever is greater.
9. Repeat item "e", "f" & "g".
10. Repeat "h" & "i" for each additional zone.
11. Place all switches in the "off" position.
12. Remove black PVC hose, dry, and glue coupling with air release valves.

II. Field Flush Flow Test

1. Determine each zone flushing GPM by multiplying the number of lateral connections by 1.6 and adding to the dosing GPM ("a" below). Should not exceed 15 GPM for the two disc filter rack.
2. Switch pump to "Hand" position. Pump should dead head with no flow meter movement.
3. Place disc filter backwash to filter #1 position. Note blue valve opening. Backwash for 15 seconds,Place disc filter backwash switch to the "Auto" position.
4. Place disc filter backwash to filter #2 position. Note blue valve opening. Backwash for 15 seconds, Place disc filter backwash switch to the "Auto" position.
5. Place disc filter backwash to filter #3 position. Note blue valve opening. Backwash for 15 seconds, Place disc filter backwash switch to the "Auto" position.
6. Turn switch for "Zone #1", "Zone Master" and the "Zone Return Valve" to hand position to manual flush. After water starts flowing through zone return valve flush for three (3) minutes, check flow rate and compare with design flushing flow rate.
7. Place all switches in the "off" position.
8. Repeat item "b", "c", "d" , "e" & "f" for each additional zone.
9. After flushing the last zone leave the pump and zone valve on and close the zone return valve. After the flow rate stablizes comparefs to design, see next section.

III. Field Dose Flow Test

1. Determine each design zone dosing Gallons Per Minute (GPM) by the following formula: (If installed as designed refer to calculation sheet.)
   
2. Determine dosing flow rate in the last zone flush tested. The rate Should be close to value calculated in "a" above. Check for leaks and repair as necessary.
3. With all toggle switches in the "off" position, backwash disk filters as described above in II. "b", "c", & "d".
4. Switch next Zone and "Zone Master" to "Hand" position and make sure Zone Return is in the "off" position, watch flow meter slow as system fills. When pressurized, measure flow rate with watch. The rate Should be close to value calculated in "a" above. Check for leaks and repair as necessary.
5. Repeat for each additional zone.
6. Place all switches in the "Auto" position.

IV. Zone Return Flow Test

1. In some cases when the drip field is around 10' in elevation above the hydraulic unit or when it is significantly above the unit the valve will not close properly and continue to recycle wastewater back to the septic tank. If this condition occurs, follow the following steps.
2. Remove the zone return connection and reinstall a short 1" nipple in the return valve.
3. Place the "return pressure assembly" in the return line as per standard detail.

1. Operational Checklist - American Septic Drip

I. Field Conditions

1. Walk the field to determine if wet spots are visible.

II. Control Lights and Manual Switch Positions

1. Open the control panel and open the lid to the hydraulic unit.
2. Make sure all manual switches are in the automatic position.
3. Microprocessor on; power light and run light
4. Microprocessor input; see owners manual table
5. Microprocessor output; only when in operation

III. Pump Tank Liquid Level

1. Check liquid level in pump tank to confirm switch operation. If a float is down its light should be off.

IV. Pump and Valve Operation

1. Place pump "Hand-Off-Auto" switch in the "Hand" position to dead head pump against valves. The flow meter should not turn, and there should be no leaks.
2. With the pump running, place each zone valve in the "Hand" (open) position one at a time to check operation. With the zone valve open, flow should register on the flow meter. When the zone valve closes (off position), the flow should stop.
3. With the pump in the "Hand" position open the filter backwash valve for filter one (1) for 10 seconds then close. Repeat for filter two (2) position for 10 seconds. There should be no flow registering in the flow meter and you should hear the valves open and close. The valve diaphragm will rise then lower during backflush.
4. Return all switches to the automatic position.

V. Extended Check - Zone Dose Rates

1. Open the air release valve boxes and inspect. Make sure they close during dose (they should not leak water after air is evacuated).
2. Determine how many zones are in operation and the installed flow rates from the installation records.
3. With the pump and "Zone Master" in the "Hand" position, select the first zone by placing the zone valve switch in the "Hand" position. After pressurization time, check flow rate by reading the flow meter for a timed minute. Repeat for all zones. If flow varies by more than 10% from original flow rate, contact qualified operator.
4. After the final zone is checked, place the "Zone Return" valve in the "Hand" position while the "zone valve" and "Master Valve" is still in the "Hand" position and verify that the flow rate increased to provide field flushing.
5. Return all switches to the automatic position.
6. Press reset button for 5 seconds and check zone dosing time.
