1. Introduction
Thank you for choosing the iCON NXT Pro Intelligent Pump Controller.
The iCON NXT Pro is a DUAL MODE, digital pump pressure controller suitable for
controlling single phase pumps up to a maximum of 16 amps (approx. 2.2kW)
When operating in Mode 1, the iCON NXT Pro behaves as a traditional pressure controller.
It starts the pump by registering water pressure drop and stops the pump when flow through
the controller falls sufficiently. The pump start pressure is able to be set by the user.
In Mode 2, the iCON NXT Pro behaves as an electronic pressure switch with dry run
protection where, the pump operates when water pressure falls below the starting pressure
and stops when the upper setting is achieved. Both the start and stop pressure can be
selected by the user. (A Pressure Tank is required if operating in Mode 2)
The iCON NXT Pro offers a number of other protection and control options to ensure the
durability of your pumping system.
2. Key Features
•Electrical components are completely isolated from the water flow.
• The Digital display provides real time information of the pressure, the pump
current draw and can also indicate visually whether there is flow or no flow.
•Built in pump protections:
▪Dry run sensing and auto restart function when water supply is available
▪ Prevents the pump from starting and stopping too often.
▪ Over pressure protection
▪ User programmable overload protection
▪ User programmable Dry Run underload protection
▪Anti-seize function if pump has not operated for the last 24 hours.
▪ User programmable maximum pump run time setting.

6. Warnings
Read the manual carefully before starting and retain for future
reference.
Prior to starting installation or maintenance, the controller
must be disconnected from the power supply and pressure
relieved from the system including controller, pump and
associated pipework.
Any changes or modification to the wiring must be carried out
by suitably qualified personnel.
A qualified electrician should correctly size and install circuit
breakers to protect the power supply. The fitment of additional
surge protection is recommended.
Never open the cover while controller is connected to
electrical supply.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of
the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play
with the appliance.
Never connect AC power to the output terminals. This will
cause damage to the controller not covered under warranty.

6.1 Cautions
6.1.1 Ensure the controller is suitable for the pump (see Section 5. Technical Data).
6.1.2 The controller is designed for use with clean water. Contamination including sand or
mineral deposits may affect the operation of the controller.
6.1.3 Remove any shipping plugs from the suction and discharge ports.
6.1.4 There are no serviceable parts in the NXT Pro controller. It should not be dismantled.
6.1.5 No regular maintenance of the NXT Pro controller is required.
6.1.6 Fitment and replacement must be carried out by competent, skilled and qualified
personnel.
6.1.7 Avoid installing the NXT Pro controller where it could experience the following
conditions:
▪Where there is significant vibration and/or mechanical shock.
▪Where it could be exposed to corrosive liquids or gasses, or to flammable
materials, solvents etc.
▪Extreme heat and cold. Operating range 3oC - 50oC.
▪Protect the controller from rain and moisture.

7. Electrical Connections
Always use an electrical outlet that is protected by Residual Current Device (RCD)
Safety Switch with a trip current of 30mA or less. A Safety switch is required by
Australian/New Zealand Standard AU/NZS 60335.1-2011.
If the supply cord is damaged, it must be replaced by a special cord or assembly
available from White International Pty Ltd or its service agent.
The iCON NXT Pro is supplied with a 10 amp rated lead and AS/NZ 3112 (Type 1) 3 pin
male power plug for connecting to mains power.
The ‘Plug and Play’ version of the iCON NXT Pro is fitted with a 10 amp rated IEC C13
appliance connector.
When the iCON NXT Pro is purchased as CONTROLLER ONLY it is supplied with a 2 core
and earth power cable for connection to the pump’s electric motor. This must be connected
by a suitably qualified technician.
An optional 15 Amp rated power cord kit is available as an accessory.
There is an additional earth wire inside the controller
which provides protection in the event of flooding.
Additional Earth Connection
