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?
2. Has any damage been caused during delivery?
3. Are the pipe/valve ancillary parts you asked for included as requested?
IMPORTANT - This manual has been produced for the specific use of the Newton TAS250 pump and should be the main
reference document for the installation and safe use of the pumps. Please also familiarise yourself with the manual included in
the packaging. With manual versions of the pumps, it is imperative that the installation manual of the control panel or pump
controller is read in conjuction with this manual.
SPECIFICATIONS
Check the nameplate for your pump’s specification as the table above. Be careful not to exceed the given specifications in the use
of your pump.
LIMITATIONS

Newton TAS250 Pump can be used for both permanent and temporary installation. They are not suitable for the pumping of
effluent or sewage. Do not let the pump run dry. The pump cannot be used for sea water and inflammable, 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

NEWTON PUMPS, PUMPING SYSTEMS AND ANCILLARIES
INSTALLATION
• Do not work on pump until power is unplugged
• Do not cut off ground pin or use an adapter tting
• Do not use an extension cord
• Before installing or servicing this pump, be certain pump power source is disconnected
• 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 basin 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
• Do not use the pump if it is damaged
Overload protection:
Newton TAS250 includes 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 TAS250 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 confirming the ‘ON’
position. Pumps may be plugged into wall sockets and again these should be switched and have neon light notification of the ‘ON’position. It is
recommended that the spur or socket have a label confirming that the switch must not be switched off unless in an emergency.
The spur or socket should be located in direct eye sight line of the sump and to the wall closest to the sump so that in an emergency it is obvious
which switch(es)will turn off the pumps.
SUPPLIED FITTINGS
Newton TAS250 is supplied ready to receive pressure rated pipe, the recommended pipe for pumps. The data sheet confirms the supplied pipe
and valve options. The correct pipe, valves and pipe fittings should be ordered prior to installation.
Fit the pump into the sump chamber with correctly sized and cut pipework and pipe fittings, 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 & qualified persons only.
TROUBLESHOOTING - DISCONNECT PUMP FROM MAINS & CONVERTER POWER SUPPLY
• Pump(s) must receive power directly from a fused switched spur that is in line of sight 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 3

PROBLEM POSSIBLE CAUSES
Pump motor
hums but no
water is be-
ing 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 flow.
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 may be set too low –pump has removed as much water as it can but cannot switch off. Raise float 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
out sump
but does not
stop
Switch may be caught and so unable to reach the ‘OFF’position. Make sure switch is unhindered in its operation.
Possible defective vertical switch. Speak with Newton Waterproofing Systems with a view to replacing with vertical switch.
Float may be set too low –pump has removed as much water as it can but cannot switch off. Raise float so that the pump turns off before
pumping out all the water it can.
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 float so that the pump turns on and off to remove the optimal vol-
ume 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. 5 amps should be used.
Circuit breaker could be too sensitive. Use 30mA breaker.
Motor runs
for a short
time, then
stops
Inlet openings in pump base may be clogged. Remove pump and clean the openings.
Pump impeller may be partially clogged with foreign matter, causing motor to run slow and overload. Remove pump and clean.
Motor starter may be defective.
Impeller may be fully or partially clogged. Remove pump and clean.
