4: PIPING
4: PIPING
General
NOTE: All plumbing work must be performed by a
qualied 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 Teon 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 qualied 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).

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.

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
