NEWTON TITAN NP400 – INSTALLATION INSTRUCTIONS
The pump is supplied with a one-way valve (check valve). This prevents water within the discharge
pipe falling back into the chamber. The check valve is the interface for connecting the waste pipe.
The check valves supplied are designed to be used with 40mm PVC solvent weld waste pipe. This
is the standard pipe found in all plumbing supplies and DIY stores. The check valves have a rubber
coupling above the one-way valve. Check the direction of flow to ensure the valve is facing the
correct way. This rubber coupling has an internal diameter of 48mm and has a jubilee clip for
tightening to the waste pipe.
You need a 40mm waste pipe straight connector to fit into the rubber coupling. These have an
external diameter of 48mm and fit into the rubber coupling. 40mm waste pipe then fits into the
straight connector.
Use of two NP400’s in a two-pump installation
In a two-pump installation, it is beneficial to have one pump set to start before the other so that the
alarm has space to operate in the event of failure of pump one. It is very simple to set one switch
above the other so that one NP400 pump to comes on before the other.
ELECTRICAL CONNECTION
The unit should be wired to either a socket via a plug, or hard wired. In both instances, a 5 amp fuse
should be used. It is advised that an independent feed be used from the consumer box so that the
unit is not affected by the tripping out of other electrical devices.
WARRANTY
The pump has a 1-year warranty from the date of proven first installation or the date of sale if this
cannot be proven. If the pump fails within this period we will replace the pump and investigate the
failure. If the failure is due to negligence or miss-use, all warranties are voided. If the pump is found
to be in full working order, it will be returned, and any replacement pump sent to you will be billed
for.

It is advisable to put some
form of demountable
connection to the horizontal
pipe within the chamber to
allow easy removal of the
pump system for maintenance.
Rubber couplings or rubber in-
line check valves can be used
for this.
