4: PIPING

4: PIPING General

NOTE: All plumbing work must be performed by a

qualied technician. Always follow all local, state and provincial codes.

A proper installation requires a pressure relief valve, a ¼" female N.P.T. threaded tting (found on tank tee) for the pressure sensor, and properly sized pipe. Piping should be no smaller than the pump discharge and/or suction connections. Piping should be kept as short as possible. Avoid the use of unnecessary ttings to minimize friction losses.

Some pump and motor combinations supplied with this system can create over

200 PSI. Select pipe and ttings accordingly per your pipe suppliers’ recommendation. Consult local codes for piping requirements in your area.

All joints must be airtight. Use Teon tape or another type of pipe sealant to seal threaded connections. Please be careful when using thread sealant as any excess that gets inside the pipe may plug the pressure sensor.

Galvanized ttings or pipe should never be connected directly to the stainless steel discharge head or casing as galvanic corrosion may occur. Barb type connectors should always be double clamped.

Pressure Tank, Pressure Relief Valve and Discharge Piping

The standard Hydro-Pro tanks have a pre-charge of 38 PSI. Set the tank pressure, while tank is empty of water, to 20 psi below the desired system pressure setting. Ex. for a 50 psi system pressure, charge the tank to 30 psi. Use a higher tank pre-charge setting if the system drifts over 5 PSI at a constant ow rate. Use only “precharged” tanks on this system. Do not use galvanized tanks. Select an area that is always above 34º F (1.1º C) in which to install the tank and pressure relief valve. If this is an area where a water leak or pressure relief valve blow-off may damage property, connect a drain line to the pressure relief valve. Run the drain line from the pressure relief valve to a suitable drain or to an area where water will not damage property. Use the supplied tank tee to connect the discharge pipe to the pressure tank and house plumbing. It is allowable to pump to multiple locations.

Maximum working pressure of most HydroPro tanks is 125 psi. Check the tank

label or instruction manual to verify data.

Installing the Pump

WARNING: Risk of electric

shock - This pump system has not been investigated for use in swimming pool areas.

Plumb suction and discharge of pump into piping. Locate the pump as near liquid

source as possible. When pumping out of an atmospheric tank locate the pump below the level of the liquid in the tank. All piping must be supported independently of the pump. Be sure that suction and discharge piping are in line with the suction and discharge of the pump. Install a check valve between the discharge of the pump and the pressure sensor and tank. For additional information refer to Installation, Operation and Maintenance Instructions supplied with the pump.

Installing the Pressure Sensor

Install the pressure sensor in the tank tee provided with the unit. The pressure sensor cable supplied with the controller is 120 inches long. Locate the controller so there will be enough cable to properly install the pressure sensor.

Do not install any shut-off valves, lters or

ow/pressure control devices (except for

a check valve) between the pressure sensor and the discharge of the pump as this could create a hazardous situation.

Use ONLY the pressure sensor provided with the unit. Install the pressure sensor into one of the ¼" holes on the tank tee provided in the kit. Install the pressure sensor vertically to avoid accumulation of debris in the sensor port. Do not install the tank tee with the ¼" holes facing down. Align the connector on the end of the pressure sensor cable with the mating connector on the pressure sensor and push it on. The tab will lock it in place. Prevent water from following the cable and entering sensor connector by creating a “drip loop” in the cable.

5: MOUNTING THE CONTROLLER

5: MOUNTING THE CONTROLLER General

Mount the controller in a well ventilated, shaded area using the supplied mounting kit. The controller must be mounted vertically. Be sure to leave 8 inches of free air space on every side of the unit. The controller must be in an area with an ambient between 34º F (1.1º C) and 104º F (40º C). Model 2AB2 will automatically decrease

(derate) the maximum output current of the drive (6.9A) if the ambient temperature exceeds 104º F (40º C). The maximum output current of the drive will be decreased by 0.069A for every degree Fahrenheit above 104º F, or -1%/º F. The maximum output current of the drive will be decreased by 0.12A for every degree Celsius above 40º C, or -1.75%/º C. Model 1AB2 does not require ambient derating and will maintain a maximum output current of 4.2A in high ambient temperatures. If installation is more than 3300 feet above

sea level, drive output should also be derated by 2% per 1000 feet above 3300 feet.

NOTE: Do not block the heat sink (ns) and do not set anything on the units.

6: POWER SUPPLY AND WIRING

6: POWER SUPPLY AND WIRING Power Supply

The 1151AB2 Controller requires a single phase power supply of 115 volts +/– 15%.

The 1AB2 and 2AB2 Controllers require a single phase power supply of 230 volts +/– 15%. All controllers require a dedicated 20 amp two-pole circuit breaker. A dedicated circuit means no other appliances use the same circuit! The output power from the motor controller is three-phase, variable frequency and variable voltage. Maximum output voltage and frequency are line input voltage and 60 Hz, respectively. Low supply voltage will reduce pump performance.

NOTE: Installation and maintenance MUST be performed by properly trained and qualied personnel. Always follow the National Electric Code or Canadian Electric Code, as well as all local, state and provincial codes when wiring the system.

Wire and Conduit

Do not use wire smaller than 14 AWG. Use of Metal Conduit with Metal Conduit Connectors is recommended for all electrical connections.

Output Power Connections

Connect the motor leads for 230 volt or

208 volt operation using the nameplate as a

reference. Connect the output power leads from the controller to the 3 motor leads in the conduit box on the motor. Connect the ground (green) output power lead to the ground screw in the conduit box on the motor. This step is performed in its entirety at the factory for complete systems. See diagram 4 for details.

NOTE: If the pump has more than 50 feet of wire from the controller, consult factory for selection of an output load lter (load reactor).

to properly ground the controller or motor will create an electrical shock hazard.

NOTE: Do not use GFCI protection with this controller. Nuisance tripping will result.

7: STARTING THE SYSTEM

Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and circuit breaker before servicing.

Once the controller is powered it will remain electrically charged for 5 minutes after

power is turned off. Wait 5 minutes after disconnecting power before opening controller access cover as there is a severe shock hazard.

Setting the Motor Overload Switches

When the unit is powered, the Motor Over-

load Setting Switches are at a high voltage

potential. DO NOT touch the Motor Overload Setting Switches while the power is on.

The Motor Overload Setting Switches adjust the level of motor overload current protection needed to protect the motor from damage due to overcurrent conditions. Turn the circuit breaker and disconnect switch to the off position, and wait 5 minutes. Remove controller access cover. On the inside of the access cover is the Motor Overload Setting table. shows the switch setting for the desired Motor Overload Setting. Read the Service Factor Amps off the motor nameplate. Use the Motor Overload Setting table to match the Service Factor Amps (SF Amps) of the motor to the correct switch setting. the Motor Overload Switches according to the correct combination on the table. If the Service Factor Amps of the motor do not match any of the Motor Overload Settings, use the next lowest switch setting.

Connecting Input Power

Connect the single-phase power supply leads and Safety Ground wire from a 20

amp two-pole circuit breaker (in the OFF position) to one side of a 20-amp two-pole disconnect switch. Connect the input power leads supplied with the controller to the other side of the disconnect switch. Be sure to use Metal Conduit with Metal Conduit Connectors for electrical connections.

The controller has a high leakage current

to ground. The terminals marked "GND"

in the controller must be connected to the safety ground from the electrical service entrance. Failure

Failure to perform this step will result in

loss of Motor Overload Protection and will void the Motor Warranty. Nuisance Motor Overload Error tripping or motor damage can occur if these switches are not set properly.

Setting the Pressure

Turn the circuit breaker and disconnect switch to the off position, and wait 5 minutes. Remove controller access cover. Open a faucet in the system and turn the breaker/ disconnect switch to the ON position. The pump will start and pressure will increase to the factory preset 50 PSI. After the pressure has stabilized, use the Increase/ Decrease Pressure Adjust Pushbuttons on the right-hand side of the controller to adjust the pressure setting.

Push and Hold the Increase or Decrease Pressure Adjust

Pushbutton until the desired pressure setting is reached. The new pressure setting is automatically saved. Close the faucet and turn power to controller off. Wait 5 minutes before installing the controller access cover.

NOTE: The maximum allowable pressure setting is 85 psi.

NOTE: It is possible for the pump to maintain constant pressure with a low ow or a high positive suction head even if the pump is rotating backwards. While the pump is running, use an amp probe on one of the output power leads connected to the motor and compare the current draw between the two rotation directions. The lowest current reading indicates the pump is running in the correct direction.

Setting the Application Switches

When the unit is powered, the Application Setting Switches are at a high voltage potential. DO NOT touch the Application Setting

Switches while the power is on.

The controller has 6 possible Application Settings. These settings are used to adjust the Minimum Speed of the motor and the Ramp Setting, or acceleration and deceleration ramp. This allows the controller to t a wide range of applications.

Before adjusting the Application Switches, turn the circuit breaker and disconnect switch to the off position. Wait 5 minutes. Remove the controller access cover. On the inside of the access cover is the Application Switch Setting Table. See Diagram 6 for details. This table shows the switch setting needed for the desired system response.

See Diagram 3 for details.

Select a Minimum Speed of 10 Hz if the pressure at the pump’s suction is within 20 PSI of the desired pressure setting. Select a Minimum Speed of 30Hz if the pressure at the pump’s suction is more than 20 PSI below the desired pressure setting, if pumping from a tank or if drawing a suction lift.

Changing the Ramp Setting changes how fast the controller can change the speed of the motor. A Slow Ramp Setting allows the controller to work better in applications where the average demand for water is low (less than 3GPM or about 1 faucet). A Fast Ramp Setting allows the controller to work better in applications where the demand for water is high because the motor is allowed to change speed faster.

System Status

The controller is always powered. A Solid Green Status Code indicates that the pump is in standby mode (pump not running) or that the line input voltage is low.

Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and circuit breaker and wait 5 minutes

before servicing.

A Blinking Green Status Code indicates that the pump is running. A Blinking or Solid Red Light indicates a problem with the controller. Refer to the access cover side panel or Diagram 6 for Status Codes. See Section 9

for more details.

NOTE: The Application Switches are preset at the factory to “0000” or Minimum Speed = 30 Hz, Ramp Setting = Fast.

Motor Rotation Direction

If the pressure or ow seems low, check motor rotation direction. Turn the circuit breaker and disconnect switch to the off position, and wait 5 minutes. Switch any two leads on the controller output (T1, T2, or T3). Turn the circuit breaker and disconnect switch to the on position. Observe pressure and ow. If pressure or ow still seems low check plumbing.

9: TROUBLESHOOTING General

The Aquavar ABII is a self-diagnosing controller. If a problem occurs, observe the Status Code Indicator Light on the front of the unit. No Status Code Indicator Light means either no or low input voltage (less than 50 V).

Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and circuit breaker and wait 5 minutes before servicing. High voltage may still remain on controller.

Refer to the status code label on the side of the controller access cover to diagnose system errors. See Diagram 6 for details.

USE THE FOLLOWING TABLE TO HELP TROUBLESHOOT PROBLEMS.

GREEN LIGHT CODES

Indicator Code Status Description

Constant Standby/Low Voltage Constant Green Light indicates the pump is off. The system is in Standby mode when there is no ow in the system and the pressure setting has been reached. The system is in a Low Voltage condition when the line input voltage drops below 196VAC for 1AB2 and 2AB2 controllers and 98VAC for 1151AB2 controllers.

Blinking Pump Running Flashing Green Light indicates the pump is running. If pump is not running, turn off power to controller and wait 5 minutes. Check output power connections from controller to motor.

RED LIGHT CODES

Constant Controller Error Replace Aquavar ABII Controller 1 Blink No Water/Loss Of Prime This fault is indicated if the system pressure drops 5 PSI or more

below the set pressure and the output current is less than 75% of the motor overload setting for 10 seconds. The system will automatically restart in 5 minutes. If 3 faults occur in an hour, the system will not restart and will need to be manually reset. If the problem reoccurs, please verify supply capacity, pump capacity, proper setting of the motor overload switches and that there are no restrictions between the supply and the pump.

2 Blinks Tank Water-Logged This warning is indicated if there is a drastic drop in system pressure in a short amount of time. The warning will not impact operation. The pump will continue to run. This warning can be caused by low air pressure in the tank or the tank bladder may have failed. This can also be caused by extreme changes in ow. The error is cleared each time the pump starts. If the error reoccurs often, check the air pressure in the tank. Before checking tank air pressure, turn power to control off to prevent pump from turning on. Relieve system pressure by opening a faucet.

3 Blinks Pressure Sensor Fault This fault indicates a problem with the pressure sensor feedback. Verify the connections from the Aquavar ABII Controller to the pressure sensor. Turn power to controller off and wait 5 minutes. Remove controller access panel. Be sure sensor cable is wired as shown in Diagram 4. If cable is wired correctly, check the voltage on the Input (White) pressure sensor terminal connection in the Aquavar ABII controller. Using a DC voltmeter, connect the positive lead to the Input (White) pressure sensor terminal connection, connect the negative lead to the Com. (Black) pressure sensor terminal connection. Turn power to controller on. The DC voltage measured should be in the valid range of 0.5 Vdc to 4.5 Vdc (+/- 0.2 Vdc). If the voltage is outside this range, replace pressure sensor.

4 Blinks Pump or Motor Bound This fault can be caused by mechanical binding from debris in pump or from an electrical failure in the motor. Verify the error by turning power to controller off for 1 minute and then on. Pump must be checked if error persists.

Indicator Code Status Description 5 Blinks Short Circuit Check wiring for shorting phase to phase and phase to ground. Turn

power to controller off and wait 5 minutes. Remove controller

access panel. Disconnect motor leads marked T1, T2, and T3. Measure resistance between all motor leads using an ohmmeter. NOTE: Motor winding resistance is typically 2 to 10 OHMS depending on motor.

6 Blinks Ground Fault Check wiring for shorting phase to ground. Turn power to controller off and wait 5 minutes. Remove controller access panel. Disconnect motor leads T1, T2, T3, and Ground from controller. Measure resistance between all motor leads and ground using a Megohmmeter. Connect one Megohmmeter lead to any one of the motor leads and the other to ground lead. Set Megohmmeter to 500V DC output. Resistance readings less than 500,000 ohms or 0.5 Megohms indicate a damaged motor.

7 Blinks High Temperature This fault is caused by a high temperature inside of the controller. The controller will shut off when the temperature inside the controller reaches 158º F (70º C). The controller will turn back on when the temperature inside the controller reaches 150º F (65.5º C). Avoid installing the controller where ambient temperatures exceed 104º F (40º C). Avoid installing the controller where it is exposed to direct sunlight.

8 Blinks Over Voltage Measure input voltage using an AC voltmeter. Connect the positive and negative leads to L1 and L2 on the Aquavar ABII controller. Verify line input voltage is not greater than 264 VAC for 1AB2 and 2AB2 controllers and 132VAC for 1151AB2.

9 Blinks Motor Overload This fault is indicated when the current supplied to the motor exceeds the Motor Overload Setting on the Aquavar ABII controller. Refer to Section 7, Setting the Motor Overload DIP Switches for details. If switches are set according to Section 7, check motor.
