2 Capacitors inside the Artesian Drive controller can still hold a lethal voltage even after power has been removed. Allow 10 minutes for dangerous internal voltage to discharge before opening the unit. Do not use power factor correction capacitors with the Artesian Drive. Damage will result to both motor and drive. Electrical installations shall be in accordance with National Electric Code (NEC) and all applicable local codes and ordinances. A licensed electrician should perform installation. Be sure system is connected to a circuit equipped with a fuse or circuit breaker of the correct rating. This unit not tested for use in swimming pool areas. How it Works The F&W Artesian Drive is designed to be part of a system that consists of only four major components: A. Standard Pump and Three Phase. B. Artesian Drive Controller. C. Small Tank (for tank size, see Table 2). D. (provided). Relief Valve Tank Inlet Pump Outlet Leads Always disconnect power source before performing any work on or near the controller, motor or its connected load. If the power disconnect point is out-of-sight, lock it in the open position and/or tag it to prevent unexpected application of power. Failure to do so could result in fatal electrical shock or bodily injury. Power Supply from Circuit Breaker Power to Leads Constant Diagram IL0759 DO NOT handle pump with wet hands or when standing in water as fatal electrical shock could occur. Disconnect main power supply before handling system for any reason. Protect the power cable from coming in contact with sharp objects, oil, grease, hot surfaces or chemicals. DO NOT kink the power cable. If damaged replace immediately. NEVER leave the control box, fused disconnect switch, or covers open (either partially or completely) when not being worked on by a competent electrician or repairman. Always use caution when operating electrical controls in damp areas. If possible, avoid all contact with electrical equipment during thunderstorms or extreme damp conditions. Figure 2a - Constant Diagram for booster pumps Power Supply from Circuit Breaker Outlet Inlet Leads Power to Relief Valve Pump Tank Leads IL1200 Figure 2b - Constant Diagram for centrifugal pumps Install all electrical equipment in protected area to prevent mechanical damage which could produce serious electrical shock and/ or equipment failure. DO NOT use this system to pump flammable liquids such as gasoline, fuel oil, kerosene, etc. Failure to follow the above warning could result in property damage and/or personal injury. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Do not pump water above 140 degrees Fahrenheit. 2 ( / FW1135) Constant The F&W Artesian Drive provides consistent pressure regulation using custom programming to run a standard motor and pump according to the pressure demands indicated by a heavy duty pressure switch. By adjusting the motor/pump speed, the Artesian Drive can deliver consistent pressure dependably, even as water demand changes. For example, a small demand on the system, such as a kitchen faucet, results in the motor/pump running at a relatively low speed. As greater demands are placed on the water system, such as opening additional faucets or using appliances, the motor/ pump speed increases accordingly to maintain the desired system pressure. Soft Start Whenever the Artesian Drive detects that water is being used, the controller always ramps up the motor speed at the

3 same time as gradually increasing voltage, resulting in a cooler running motor and lower in-rush current compared to a motor being used on conventional water systems. If the water demand is very low, the system may cycle on and off at very low speeds, but due to the drive s soft-start feature and pressure switch s dependable design, this will not harm the motor or the pressure sensor. System Diagnostics In addition to regulating system pressure and accurately controlling motor operation, the Artesian Drive continuously scans the system and can detect a variety of abnormal conditions. If there is elevated risk of damage to a part of the system, the drive will protect the system and display a code for the fault. If possible, the drive will try to restart itself when the fault condition passes. Pump Sizing Artesian Drive (Centrifugal) The Artesian Drive is configured at the factory for use with standard 3-phase motors and pumps. NOTE: The Artesian Drives are factory programmed to F&W pumps to provide optimum performance and motor protection. The Artesian Drive can be used with other pumps, but the maximum motor amperage needs to be compared to the factory programmed current value (refer to the Specifications section under the appropriate model). If the maximum motor current varies more than 5% from the programmed value, the motor current value in the drive needs to be changed for motor protection and optimum performance. For details on how to change this value in the drive, please contact Technical Support at The rated current must be set correctly to avoid a risk of fire in the event of a motor overload. Drive Configuration When sized correctly, the Artesian Drive systems are ready to go right out of the box and need no configuration. Under certain circumstances there are several programming parameters that can be changed to accommodate non standard systems. For further information to change these parameters, please call Technical Support at Serious or fatal electrical shock may result from contact with internal electrical components. DO NOT, under any circumstances, attempt to modify connections to the drive until power has been removed and 10 minutes have passed for internal voltages to discharge Underload Sensitivity The Artesian Drive controller is configured at the factory to ensure detection of Underload faults in a wide variety of pumping applications including dead head and run dry conditions. In very rare cases (as with certain pumps in shallow wells) this trip level may result in nuisance faults. If the pump is installed in a shallow well, activate the controller and observe system behavior. Once the controller begins to regulate pressure, check operation at several flow rates to make sure the default sensitivity does not induce nuisance Underload trips. If it becomes necessary to desensitize the Underload trip level, please call of Technical Support at for further details. Before Getting Started Serious or fatal electrical shock may result from failure to connect the ground terminal to the motor, Artesian Drive controller, metal plumbing, or other metal near the motor or cable, using wire no smaller than motor cable wires. To minimize risk of electrical shock, disconnect power before working on or around the Artesian Drive system. CAPACITORS INSIDE THE ARTESIAN DRIVE CONTROLLER CAN STILL HOLD LETHAL VOLTAGE EVEN AFTER POWER HAS BEEN DISCONNECTED. ALLOW 10 MINUTES FOR DANGEROUS INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING ARTESIAN DRIVE COVER. Do not use motor or system in swimming areas. IMPORTANT: This equipment should be installed by technically qualified personnel. Failure to install it in compliance with national and local electrical codes and within F&W recommendations may result in electrical shock hazard, fire hazard, unsatisfactory performance, or equipment failure. Installation information is available directly from F&W at our toll-free number Use Artesian Drive only with properly sized three phase motors. Use of this unit with improperly sized motors may result in damage to both motor and electronics. Controller Location Selection The drive s enclosure is NEMA 1 rated and is intended for indoor use only. It should be mounted in a location that provides protection from water spray/drips and only be accessed by trained and authorized personnel. The Artesian Drive controller is intended for operation in ambient temperatures up to 122 F (50 C) at 230 VAC input. The following recommendations will help in selection of the proper location of the Artesian Drive unit: 1. A tank tee is recommended for mounting the tank, pressure sensor, pressure gauge, and pressure relief valve at one junction. If a tank tee is not used, the pressure sensor should be located within 6 feet (1.8 meters) downstream of the pressure tank to minimize pressure fluctuations. NOTE: There should be no elbows between the tank and pressure sensor and the tank should be between the the pump and pressure sensor. 2. The unit should be mounted on a sturdy supporting structure such as a wall or supporting post. Please take into account the weight of the unit (refer to the Specifications section under the appropriate model). 3. The electronics inside the Artesian Drive are air-cooled. As a result, there should be at least 4 inches of clearance on each side and below the unit to allow room for air flow. There should be at least 4 inches of clearance on each side and below the unit to allow room for air flow. Serious or fatal electrical shock may result from contact with internal electrical components. DO NOT, under any circumstances, attempt to modify connections to the drive until power has been removed and 10 minutes have passed for internal voltages to discharge 3 ( / FW1135)

Do not expose a Artesian Drive to rain or water spray. For outdoor installations, place the drive inside a NEMA 3R enclosure. Note: Please reference maxim temperature ratings listed above. Power Supply from Circuit Breaker Correct Power to Leads Power to Leads Figure 4 - Mounting Orientation Power Supply from Circuit Breaker IL0757 Incorrect 5. The Artesian Drive should only be mounted with the wiring end oriented downward. The controller should not be placed in direct sunlight or other locations subject to extreme temperatures or humidity (mounting location should not be subjected to freezing conditions or condensation). IL The mounting location should have access to 230 VAC 3-Phase electrical supply and to the pump motor wiring. To avoid possible interference with other appliances, please refer to the enclosed Installation Guide and observe all precautions regarding power cable routing. Circuit Breaker and Wire Sizing The minimum circuit breaker size and maximum allowable wire lengths for connection of motor to the Artesian Drive are given in the following table: Table 1: imum Breaker Size and Maximum Cable Length (in Feet) Drive Model Recommended Input Cable Recommended Cable Maximum Cable Length to Recommended (Ft.) Breaker Maximum Continuous Current AD AD AD A 10-foot section of cable is provided with the Artesian Drive to connect the pressure sensor. NOTE: Maximum allowable wire lengths are measured between the controller and motor. Aluminum wires should not be used with the Artesian Drive. Wire sizing between the service entrance and the controller must be sufficient to provide the required maximum input amps to the controller while conforming to local standards and codes. Artesian Drive minimum breaker amps may appear to exceed specifications for the three-phase motor because Artesian Drive controllers are supplied from a single-phase service rather than three-phase. Tank The Artesian Drive needs only a small pressure tank to maintain constant pressure (see table below for recommended tank size). The Artesian Drive can also use a bigger tank with a much larger capacity if available. Table 2: imum Tank Rated Pump Flow Tank Size (Total Volume) Pump Capacity less than 12 GPM 4 Gallon (AT15) Pump Capacity greater than 12 but 8 Gallon (AT25) less than 25 GPM Pump Capacity greater than 25 GPM 14 Gallon (AT44) The pressure tank pre-charge setting should be 70% of the system pressure sensor setting as indicated in the following table. Table 3: Tank Air Precharge (PSI) System (at ) Tank Precharge Setting (± 2 PSI) * 56 4 ( / FW1135)

Disconnect electrical power at the main breaker. 2. Drain the system of water (if applicable). 3. Install the pressure sensor (threaded connection down) at the pressure tank tee downstream of the pressure tank (the pressure tank should be between the pressure sensor and the pump). The pressure sensor has a 1/4-18 National Pipe Thread (NPT) connection. NOTE: The pressure sensor should not be installed in an inverted orientation (threaded connection up). Make sure the pressure sensor and tank are not located more than 3 feet off the main piping. 4. The unit should be mounted on a sturdy supporting structure such as a wall or supporting post. Please take into account the weight of the unit (refer to the Specifications section under the appropriate model). Install the unit to the wall using four mounting screws (not included) as shown in Figure in 14.5 in 8.6 in 14.6 in 4.2 in 1.0 in 13.3 in appropriate model) when installing in a through-panel configuration. Install the unit to the panel using three mounting screws (not included) as shown Figure 6. Wiring Serious or fatal electrical shock may result from failure to connect the motor, the Artesian Drive, metal plumbing and all other metal near the motor, or cable to the power supply ground terminal, using wire no smaller than motor cable wires. To reduce risk of electrical shock, disconnect power before working on or around the water system. To avoid a fire hazard and maintain validity of the UL listing, torque the power terminal screws to 13.2 lb.-in. (1.5 N-m). areas. Do not use motor or system in swimming Before beginning wiring 1. Verify that the power has been shut off at the main breaker. 2. Verify that the dedicated branch circuit for the Artesian Drive is equipped with a properly-sized circuit breaker. Refer to Table 2 (Page 8) for minimum breaker size. 3. Remove the Artesian Drive cover and bottom plate. Line up the alignment notches and slip the memory stick into the slot on the front of the controller. Note: Do not force the stick into place; it should slip into the slot and protrude about 3/4 from the face of the controller with the cover off when fully seated. (See Detail Figure 9). 4. Remove knock-outs as required on bottom plate. Install strain relief fitting (included) for the pressure sensor wire and strain relief fittings (not supplied) for the motor supply cable and power supply leads. 0.8 in Figure 5 IL The unit can also be mounted in a through-panel configuration by using the through-panel mounting bracket, mounting gasket and appropriately cut hole in the panel as depicted below.

7 Remove Rubber End Cap to Adjust with 7/32 Allen Wrench Boot Figure Set the pressure tank pre-charge at 70% of the desired water pressure setting. To check the tank s pre-charge, depressurize the water system by opening a tap. Measure the tank pre-charge with a pressure gauge at its inflation valve and make the necessary adjustments. 13. The pressure sensor communicates the system pressure to IL0730 the Artesian Drive controller. The sensor is preset at the factory to 50 psi, but can be adjusted by the installer using the following procedure: a. Remove the rubber end-cap. b. Using a 7/32 Allen wrench (provided), turn the adjusting screw clockwise to increase pressure and counterclockwise to decrease pressure. The adjustment range is between 30 and 80 psi (1/4 turn = approximately 3 psi). c. Replace the rubber end cap. d. Reset the pressure tank pre-charge to the appropriate pressure. e. Cover the pressure sensor terminals with the rubber boot provided. When increasing the pressure, do not exceed the mechanical stop on the pressure sensor or 80 psi. The pressure sensor may be damaged. Diagnostic Fault Codes Should an application or system problem occur, built-in diagnostics will protect the system. The display will change to indicate the nature of the fault. In some cases, the system will shut itself off until corrective action has been taken. Fault codes and the recommended corrective action for each are listed in the following chart. Do not attempt to carry out internal repairs. Return a faulty drive to the supplier for repair.

Waterlogged tank. tank is too small for flow rating of the pump. Leak in the household or outdoor plumbing. Leak in the pitless adapter. NOTE: Ensure that the system is properly grounded all the way to the service entrance panel. Improper grounding may result in the loss of voltage surge protection and interference filtering. Special Instructions for Outdoor Installation To install the Artesian Drive in an outdoor installation, the drive must be placed inside NEMA 3R enclosure (Not Included). Start-Up and Operation Apply power to the controller. As long as the display is lit up the system has power. When the display shows. or flashes PLC as shown, the system is active, but the pump is not running. The display will show. as shown (where the numbers may be fluctuating) when the pump is running. Figure 14 IL ( / FW1135) Make sure there is at least 4 inches of room around the controller for movement of air. Avoid direct sunlight. Reduce ambient temperature below 104 F (40 C). Increase input voltage if below 230 VAC. Check motor, motor wiring and splices. Make certain all connections are tight. Check tank for bladder damage. Replace if necessary. Reset the tank pre-charge pressure (should be 70% of pressure sensor setting). Use larger tank (refer to Table 3 on Page 4 for minimum Tank size). Check for leaky faucets, valves and/or pipe fittings and repair. Re-seat the pitless adapter. Replace seal as needed. Leaky Systems Leaky water systems might keep the controller running due to the accurate pressure sensing capability of the pressure sensor. Continuous running or starts and stops do not hurt the controller, pump or motor. However, to reduce the on-time of the controller/pump/motor, a Bump-Mode procedure has been programmed into the drive. During very low flow (or leaky) conditions this feature periodically increases the speed of the pump several PSI above the set point and shuts off the pump. This adds some time to bleed off before the system starts up again. This Bump-Mode can be turned off if desired. Please call Technical Support at for further details. NOTE: Artesian Drive maintains a constant pressure at the pressure sensor. Although the pressure is constant at the pressure sensor, pressure drops may be noticeable in other areas of the system when additional taps are opened. This is due to restrictions in the plumbing and will be more pronounced the farther the taps are from the pressure sensor. This would be true of any system, and if observed, should not be interpreted as a failure in the performance of the Artesian Drive. Although the pressure sensor can be adjusted up to 80 PSI, the maximum obtainable pressure in the system is dependent upon the full load capability of the pump at a given flow. For example, a pump is only capable of producing a pressure of 60 PSI at the flow demand. Increasing the pressure setting of the pressure sensor to 75PSI would only result in the pump running at full speed and producing a pressure of 60 PSI. Underload Intelligent Reset (Display showing ) If a motor Underload fault condition occurs, the most likely cause is an overpumped well (dry well) or loss of incoming feed water to the pump. In a dry well situation to allow the well to recover, the Artesian Drive controller will wait 30 seconds to 5 minutes, determined by the amount of time the motor had been running before sensing the underload, before restarting the motor. For example, the first time the fault occurs and the pump has been running 6 minutes, the controller stops the motor and will wait 30 seconds before attempting to restart the pump. If the system would then run for 2 minutes and an underload fault recurs, the controller will wait 3 minutes before attempting to restart the pump. This schedule allows for the minimum off-time possible based on the recovery time of the well or water feed supply. If there is an obstruction (such as a closed valve) between the pump and the pressure sensor, the controller will also sense an underload is this dead head condition stopping the motor to avoid damaging the pump.

9 Off Time (.) Run Time (.) Figure 15 IL0750 Over-Temperature The Artesian Drive controller is designed for full power operation in ambient temperatures up to 104 F (40 C) as long as the input voltage is kept at 230 VAC. Under extreme thermal conditions, the controller will reduce the switching frequency in an attempt to avoid shutdown. If the temperature of the controller is still too hot the controller will shut itself off to avoid causing damage to itself. Full pump output is restored when the controller temperature cools to a safe level. NOTE: The Artesian Drives are factory programmed to F&W pumps to provide optimum performance and motor protection. The Artesian Drive can be used with other pumps, but the maximum motor amperage needs to be compared to the factory programmed current value (refer to the Specifications section under the appropriate model). If the maximum motor current varies more than 5% from the programmed value, the motor current value in the drive needs to be changed for motor protection and optimum performance.
