General
NOTE: All plumbing work must be performed by a
qualified technician. Always follow all local, state and
provincial codes.
A proper installation requires a pressure relief valve, a ¼"
female N.P.T. threaded fitting (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 fittings to minimize friction
losses.

per your pipe suppliers' recommendation. Consult local
codes for piping requirements in your area.
All joints must be airtight. Use Teflon 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 fittings 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 flow rate. Use only "pre-charged"
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

label or instruction manual to verify data.

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, filters or
CAUTION
flow/pressure control devices (except for a
Hazardous
Pressure
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.
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 (fins) and do not set
anything on the units.
