4: PIPING
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.
Some pump and motor combinations

supplied with this system can create over

200 PSI. Select pipe and fittings accordingly
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. You may set the tank pre-charge anywhere between
this value and 10 PSI below the system operating
pressure. Use the 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 Hy-

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

flow/pressure control devices (except for

Pressure
a check valve) between the pressure sen-
sor 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 (fins) and do not
set anything on the units.
