A Range of High Quality Clean Water Pumps
INTRODUCTION
Congratulations on your purchase of this pump product. All Newton pump products are developed with the help of
the latest technologies and manufactured with the most advanced electrical/motor parts.
Please check the following points upon receipt of your pump:
1. The pump is the model that you ordered. Please check the name plate.
2. Has any damage been caused during delivery?
3. Are the pipe/valve ancillary parts you requested included?
Please take the time to read these instructions carefully before using the pump.
SPECIFICATIONS
Check the nameplate for your pump’s specication in the table above. Be careful not to exceed the given
specications in the use of your pump.
LIMITATIONS
The Newton CP series pumps are suitable to pump clean water with
suspended soft solids of between 5-15mm, depending on model. Newton CP
Pumps can be used for both permanent and temporary installation. Newton
CP pumps are not suitable for the pumping of efuent or sewage. Do not let
the pump run dry. The pump cannot be used for sea water and inammable,
corrosive, explosive or dangerous liquids.
DANGER: Keep the equipment out of the reach of children
DANGER: Failure to follow the directions given could cause
serious risk to individuals or property
WARNING: Failure to follow an instruction may damage the
pump and/or the system
INSTALLATION - IMPORTANT
• Pump(s) must receive power directly from a fused switched spur that is in
line of site of the pumping station. Do not connect the pump to extension
cables
• If possible, each pump should have its own connection to the consumer
board and be protected by a 30 mA RCD
• Use the correct size fuse for the pump as conrmed on page 2

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 qualied 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 conrming the ‘ON’ position. Pumps may be plugged into wall sockets and again these should be
switched and have neon light notication of the ‘ON’ position. It is recommended that the spur or socket have a label
conrming 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 conrms 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.

ELECTRICAL PRECAUTIONS
Before servicing a pump, always shut off the main power breaker and then unplug the pump.
Make sure you are not standing in water and are wearing insulated protective sole shoes.
Connection or disconnection of the pump from the electrical supply should be by trained &
qualied persons only.
TROUBLESHOOTING - DISCONNECT PUMP FROM MAINS & CONVERTER POWER SUPPLY
PROBLEM POSSIBLE CAUSES
Pump motor hums
but no water is being
pumped
Impeller may be clogged. Free impeller from debris.
The check valve may have been installed in the wrong direction. Ensure arrow on valve is
pointing in direction of ow.
Discharge shut-off valve (if used) may be closed.
Pump could be air-locked. Start and stop several times by raising and lowering the switch.
Check for clogged vent hole in pump case.
Float maybe set too low – pump has removed as much water as it can but cannot switch
off. Raise oat so that the pump turns off before pumping out all the water it can.
* If all of the above are OK, and then the motor winding could be damaged.
Pump runs and
pumps water but
does not stop
Switch may be caught and so unable to reach the ‘OFF’ position. Make sure switch is
unhindered in its operation.
Float maybe set too low – pump has removed as much water as it can but cannot switch
off. Raise oat so that the pump turns off before pumping out all the water it can.
Possible defective vertical switch. Speak with John Newton with a view to replacing with
vertical switch.
Pumps runs but
delivers only a small
amount of water
Pump could be air-locked. Start and stop several times by raising and lowering the switch.
Check for clogged vent hole in pump case.
Float may be set with a too narrow band between ‘ON’ & ‘OFF’. Reset oat so that the
pump turns on and off to remove the optimal volume of water.
Inlet holes in pump base are clogged. Clean the inlets of debris.
Impeller or volute openings maybe fully or partially clogged. Remove pump and clean the
openings.
Pump impeller could be partially clogged with matter, causing motor to run slow and
overload. Remove pump and clean.
Fuse blows or circuit
breaker trips when
pump starts
Pump impeller or impeller housing may be partially clogged with foreign matter, causing
motor to run slow and overload. Remove pump and clean.
Motor starter may be defective.
Fuse size may be too small. CP150 – 3 amps, CP250 – 5 amps, CP400 – 10 amps, CP750 –
13 amps.
Circuit breaker could be too sensitive. Use 30mA breaker.
Motor runs for a
short time, then stops
Inlet openings in pump base maybe clogged. Remove pump and clean the openings.
Pump impeller maybe partially clogged with foreign matter, causing motor to run slow
and overload. Remove pump and clean.
Motor starter maybe defective.
Impeller may be fully or partially clogged. Remove pump and clean.
