Electrical Power Surge Protection
An electrical power surge or spike can travel on the supply lines and cause serious damage to your electrical equipment.
The controller fitted to this pump has a metal oxide varistor (MOV) fitted to help protect it’s circuit. This MOV is a
“sacrificial” device, meaning that it effectively gradually destroys itself every time it takes a surge. The MOV is not a
lightning arrestor and may not protect the controller if lightning or a very powerful surge hits the pump unit.
If the installation is subject to electrical power surges or lightning we strongly recommend the use of a suitable surge
protection device on ALL electrical equipment.
Pipe Connections
For best performance use P.V.C. or polythene pipes at least the same diameter as the pumps inlet and delivery outlet
openings. Larger diameter pipe may be used to minimise resistance to flow when pumping longer distances.
Use unions as pipe connections to enable easy removal and servicing. Use sufficient tape to ensure airtight seal and
hand tighten only. To prevent strain on pump threads always support heavy inlet and outlet pipes. If there is a likelihood
the water supply may contain solid particles such as pieces of plant or vegetable matter, a suction strainer should be
installed before the pump to avoid blocking of the pump. Lay suction pipe at a constant gradient to avoid air pockets
which reduce pump efficiency.
NOTE - Suction leaks are the largest cause of poor pump performance and are difficult to detect. Ensure all
connections are completely sealed USING THREAD TAPE ONLY.
Installations with a Suction Lift
Installations with a suction lift require a good quality foot valve to avoid loss of prime.
Installations with Flooded Suction
Installations with flooded suction require a gate valve so water supply can be turned off for pump removal and servicing.
WARNING
DO NOT RUN DRY.
DO NOT RUN WITH LOSS OF PRIME.
DO NOT PUMP WATER CONTAINING ABRASIVE MATERIALS.
Abrasive Materials
The pumping of abrasive materials will cause damage to the pump which will then not be covered by the guarantee.
Water temperature in pump must not exceed 35
o
C, or damage caused will not be covered by guarantee.
Connection of Mains Scheme or Town Water Supply to either Suction or
Discharge of Pump
Most Water Supply Authorities have strict regulations regarding
direct connection of pumps to mains water supplies. In most
cases an isolating tank is required between mains supply and
pump. This is also the recommend method for this pump.
Directly applied mains pressure can exceed pump operating
pressure and damage pump.
TotalFlo can not accept responsibility for loss or damage
resulting from incorrect or unauthorised installations.
NOTE - If connecting your pump direct to mains water, the casing pressure (maximum outlet pressure) must not
exceed 600kPa (6bar/87psi).
