NEWTON PUMPS, PUMPING SYSTEMS AND ANCILLARIES
INSTALLATION
• Do not work on pump until power is turned of at both the switched spur and at the consumer board
• If a 3-pin plug is tted for temporary use, do not use a plug adapter or extension cable
• Installation and electrical wiring must be carried out by trained and qualied personnel
• Pump must be correctly earthed
• Voltage of power supply must match the voltage of the pump
• Before installing pump, clear sump chamber of any water, debris or sediment
The following may cause severe damage to pump and will void warranty:
• Using extended wiring not suitable for the pump motor size and the distance of the extended cable
• Not having the pump correctly grounded to earth
• Working on the pump without it being disconnected
• Running the pump continuously
• Pumping chemicals or corrosive liquids
• Pumping gasoline or other ammable liquids
• Using the pump if it is damaged
Overload protection:
Newton CP pumps include a built in thermal protection switch. The pump stops if an overload condition occurs. The
motor restarts automatically after it has cooled down.
Electric Supply:
The Newton CP Pumping range requires a single phase 230V AC power supply. It is advisable that all pumps are
connected to their own individual power supply directly from the consumer board so that each of the pumps does
not share a consumer board supply with the other pump or with any other electrical circuit or device. In reality, this
is normally only achievable with new build properties or where fundamental refurbishment of the whole property,
or the electrical supply is to be undertaken. Where it is not planned or possible to have each pump connected to a
separate supply from the consumer board, it is preferable that each pump is supplied from a separate circuit. If this is
not possible, each pump should be connected to a separate fused and switched spur or socket. Each separate circuit
should have its own RCD protection as required by the 17th Edition Wiring Regulations. The RCD should be correctly
sized at 30mA so as not to trip during normal pump start or pump run parameters.
It is preferable for the pumps to be wired to the rear of a switched spur. The spur should be switched and have
a neon light conrming the ‘ON’ position. Pumps may be plugged into wall sockets and again these should be
switched and have neon light notication of the ‘ON’ position. It is recommended that the spur or socket have a label
conrming that the switch must not be switched off unless in an emergency.
The spur or socket should be tted with the correctly sized fuse appropriate to the motor size of the connected
pump.
CP150 - 3 amps
CP250 - 5 amps
CP400 - 10 amps
CP750 - 13 amps
The spur or socket should be located in direct eyesight line of the sump and to the wall closest to the sump so that in
an emergency, it is obvious which switch will turn off the pumps.
SUPPLIED FITTINGS
Newton CP Pumps are supplied ready to receive pressure rated pipe, the recommended pipe for pumps. The CP
pump range data sheet conrms the supplied pipe and valve options. The correct pipe, valves and pipe ttings
should be ordered prior to installation.
Fit the pump into the sump chamber with correctly sized and cut pipework and pipe ttings, ensuring that the pipe
build includes a means of removal of the pumps for servicing and repair.
