USE AND MAINTENANCE INSTRUCTION MANUA
TO BE KEPT BY THE USER
For three phase pumps it is imperative that electrical connections are made so that the
impellers rotate in the correct direction. If the pumps are run in the wrong direction for
more than a few seconds serious damage may result which will invalidate the guarantee.
Read paragraph 9.3 efore installation for the method of checking correct direction of
rotation.
Although the filters are self-cleaning there may over time e a uild-up of detritus in the
pores of the mesh which the self-cleaning mechanism cannot remove.
For stainless steel filter mesh use a pressure washer to very thoroughly clean the outside
of the mesh.
For nylon screens either clean low pressure water or replacement inserts are availa le
from Rotorflush Filters Ltd.
If the pump is run with the filter screen clogged it may cause the pump to overheat and
seriously damage the motor invalidating the guarantee. The use of appropriate cos phi
load monitoring and dry running protection is essential with all models.
In most conditions the filter should e inspected every 2 months. In some situations it
may require more frequent inspection and if required cleaning.
Stainless steel screens should e thoroughly cleaned with a pressure washer. Nylon
screens should e cleaned with gentle running water or replaced. It is recommended
that nylon screens are replaced at these intervals:
Nylon screens:
Stainless steel
screens:
300 micron every 5000 hours of use or every year.
115 micron every 1000 hours of use or 6 monthly.
These should e pressure washed at least every year, ut may e
more frequently depending on conditions.

8.3. Transport
The Filterpump is packed on a pallet for transport; check the gross weight before moving or transporting
these filterpumps
9. PREPARATION FOR USE (as per EEC 98/37 p.1.7.4.a, EN 292-2 p.5.1.3).
9.1. General information
Before beginning to work on the electrical pump, make sure that you have disconnected
the electricity from the power supply mains and that it cannot be accidentally
reconnected.
The voltage variation allowed +/- 5% (3-phase 380-415 V)
9.2. Electrical Connections
Connections must only be performed by an authorised electrician in compliance with the law in force. Verify
that the data on the name plate match the nominal values for the power line. Make the connection after
verifying the existence of a working grounding circuit.
It is the Installer’s responsibility to perform the connection in compliance with regulations in
force in the country of installation.
The 3-phase versions need external protection (rapid disconnect magnetic overload cut-out)
with intervention time calibrated to:
• ess than 10 seconds with 5 times IN
• ess than 10 minutes with 1.5 times IN
IN = maximum value of current shown on the name plate
The installation of a differential switch is highly recommended
9.3. Checking the Direction of Rotation
After connecting the power supply, the direction of rotation can be inverted in the three phase versions; in
this case performance will be significantly lower than the nominal values and will cause su stantial damage
to the Filterpump if run in the wrong direction for more than a few seconds and will invalidate any
guarantee.
To verify a correct connection, proceed as follows:
Start the pump before it is installed. By reaction, it must tend to rotate (“kick”) in an ANTI-CLOCKWISE
direction viewed from above (discharge end).
CAUTION! This operation will e performed dry and must not last more than a few seconds.
10. INSTALLATION (as per EEC 98/37 p. 1.7.4.a; EN 292-2 p.5.1.1 )
WARNING
TO LIFT OR LOWER THE FILTERPUMP, USE A STRONG ROPE OR CHAIN AND APPROPRIATE LIFTING
GEARFIXED TO THE EYELETS; NEVER USE THE ELECTRIC POWER CABLE.
Before beginning to work on the electrical pump make sure that you have disconnected the power supply
from the power supply mains and that it cannot be accidentally reconnected.
The installation of the electrical pump can involve a certain amount of complexity. For this reason, it must
be performed by competent and authorised installers.

The Delivery Pipe
The diameter of the delivery pipe depends on the flow rate and pressure available at the points of use. For
installations with long lengths of delivery pipe, friction loss can be reduced by using a pipe diameter larger than
the discharge outlet of the pump. It is advisable to install a check valve after the discharge outlet to avoid
dangerous water hammers in the event the electrical pump should stop suddenly. Do not use excessive force
when screwing the pipe to the discharge outlet in order to avoid damage. The electrical pump can be installed for
use with either a metal pipe (which can be used to support the pump) or flexible tubing. In the latter case the
electrical pump must be supported by a cable made of a material with long lasting resistance, passing through
the eyelets at the top of the pump. Fix the power cable to the delivery pipe using suitable straps.
CAUTION! Do not underestimate the risk of drowning if the installation must be performed in a well of a certain
depth. Make sure there is no danger of toxic vapours or harmful gases in the work atmosphere.
10.1. Fixed Installation
We strongly recommend that the pump is fitted with dry run protection, so that if the filter blocks for any
reason or there is insufficient water the pump is automatically stopped to prevent damage from dry running
10.1.1. The Filterpump may be installed upright or horizontally although the self-cleaning filter will
work better in the upright position.
10.1.2. The Filterpump should be fully submerged if possible although this is not necessary except
for frost protection. The Filterpump will operate continuously if at least 500mm of the filter
unit and suction end of the pump are submerged in water at a temperature of less than 40°C.
There must be a gap of at least 200mm around and 100mm underneath the filter unit,
although there is no need for a gap under the Filterpump when operated in the upright
position if there is a flow of fluid past the filter pump to take detritus away from the screen
(e.g. when installing in a flowing river or flume the filter unit at the suction end of the
Filterpump) at all times to allow solid particles to fall or be washed clear of the filter screen.
Due allowance must the made to allow for any build-up of solids underneath the filter and
any detritus, sludge etc must be removed from time to time to ensure this does not come
within 100mm of the filter.
When lowering the Filterpump into a well or tank, ensure that it is at least 100mm above the
bottom.
Be careful with the power cable when lowering the Filterpump. It is advisable to tie the
power cable to the delivery pipe every two or three metres.
10.1.3. When positioning the Filterpump, observe the minimum required distances (fig. 2) from walls,
from the sides of the drain, tank or other location, so as to allow functioning, use and
maintenance operations in safe conditions (as per EN 292-2 p.5.5.1.b).
10.1.4. It is recommended that standard size rigid pipes (metal or plastic) be attached to the
Filterpump with clamps of a suitable size.
10.1.5. Anchor the pipes to the edge of the basin or tank with a pipe clamping bracket.
10.1.6. If there is the need to install a non-return valve onto the delivery pipes, make sure it is placed
away from the Filterpump filter screen to avoid priming problems when first starting or after
emptying.

10.2. Temporary Installation (for Temporary Use)
10.2.1. The Filterpump may be installed upright or horizontally. (As above).
The Filterpump should be fully submerged if possible (as above) but it will operate
continuously if at least 500mm of the filter unit and suction end of the pump are submerged
in water at a temperature of less than 40°C
10.2.2. There must be a gap of at least 200mm around and 100mm underneath the filter unit,
although there is no need for a gap under the Filterpump when operated in the upright
position if there is a flow of fluid past the filter pump to take detritus away from the screen
(e.g. when installing in a flowing river or flume at the suction end of the Filterpump) at all
times to allow solid particles to fall or be washed clear of the filter screen. Due allowance
must the made to allow for any build-up of solids underneath the filter and any detritus,
sludge etc must be removed from time to time to ensure this does not come within 100mm of
the filter.
10.2.3. When lowering the Filterpump into a well or tank, ensure that it is at least 100mm above the
bottom.
10.2.4. Be careful with the power cable when lowering the Filterpump. It is advisable to tie the
power cable to the delivery pipe every two or three metres.
10.2.5. When positioning the Filterpump, observe the minimum required distances (fig. 2) from walls,
from the sides of the drain, tank or other location, so as to allow functioning, use and
maintenance operations in safe conditions (as per EN 292-2 p.5.5.1.b).
10.2.6. It is recommended that standard size rigid pipes (metal or plastic) be attached to the
Filterpump with clamps of a suitable size.
10.2.7. If there is the need to install a non-return valve onto the delivery pipes, make sure it is placed
away from the Filterpump filter screen to avoid priming problems when first starting or after
emptying.
11. ASSEMBLY AND DISASSEMBLY (as per EEC 98/37 p.1.7.4.a).
The basic Filterpump has no separate parts or accessories, so no assembly is required for installation. If
the Filterpump is to be used with the Rotorflush Valve Control System, the assembly instructions
provided with the Control Valve system must be followed.
The user must not attempt to disassem le any other component not covered in these instructions
and should contact Rotorflush Filters for advice if any further disassem ly is required.
FAILURE TO COMPLY WITH THIS RULE RENDERS THE GUARANTEE INVALID.
12. ADJUSTING AND REGISTERING (as per EEC 98/37 p.1.7.4.a; EN 292-2 p.5.5.1.d)
The only thing that needs checking once installation is complete is the length of the cable with float (in
installations that have one) with respect to the minimum and maximum water level.

Rotorflush Jasper Range 400R Instructions and Use v 3.0.docx

Page 10 of 15
13. USE AND START-UP (as per EEC 98/37 p.1.7.4.a; EN 292-2 p. 5.5.1.d)
The water level must never e lower than the filter screen, even when the pump is not eing used. If you
fail to observe this, the Filterpump will run out of water and you will have great difficulty starting the
Filterpump again.
13.1. Starting
Never continuously run the Filterpump until it is placed and installed in its final operational
position. It is possible to have leakage of the Filterpump oil into the pumped liquid;
however, this is not harmful to health.
To start up the Filterpump, connect the plug and/or turn on the switch. When the water
level reaches the minimum level (fig. 2), disconnect the plug and/or turn off the switch.
14. MAINTENANCE AND REPAIRS (as per EEC 98/37 p.1.6; EN 292-2 p.5.5.1.e)
BEFORE CARRYING OUT ANY MAINTENANCE OPERATIONS, DISCONNECT THE PLUG
AND/OR SWITCH OFF.
FOR ANY REPAIR JOBS DURING THE GUARANTEE PERIOD, THE USER MUST CONTACT
ROTORFLUSH FILTERS
FAILURE TO OBSERVE THIS RULE RENDERS THE GUARANTEE INVALID.
AFTER THE GUARANTEE PERIOD, ALL MAINTENANCE OPERATIONS, REPAIR JOBS AND/OR
REPLACEMENTS, MUST BE CARRIED OUT BY SKILLED TECHNICIANS ONLY.
To ensure correct functioning and long life of the Filterpump, the Rotorflush filter unit should be inspected
and every two – six months, depending on mesh type and water conditions. The amount of cleaning
required will depend on the liquid being pumped in some instances more frequent manual cleaning of the
filter screen may be required, for example where biological growth occurs on the filter screen or oily/fatty
deposits are found to build up on the filter screen).
Stainless steel screens should be thoroughly cleaned with a pressure washer. Nylon screens should be
cleaned with gentle running water or replaced. It is recommended that nylon screens are replaced at these
intervals for use in average conditions. Maintenance intervals will vary according to water quality and use.
Nylon screens: 300 micron every 5000 hours of use or every year. 115 nylon and 60 micron every
1000 hours of use or 6 monthly whichever occurs first.
Stainless steel screens: These should e pressure washed at least every year, ut may e more
frequently depending on conditions.
Check the condition of the electric power cable; if it is damaged, contact the dealer or Rotorflush Filters
td to have it replaced.
