1. Handlng
The pump must be lfted and handled carefully by means of the handle and the lftng holes.
2. Desgn
The pump s avalable for the transfer of clean, polluted and turbd lquds, whch contan
suspended materals that do not exceed the followng dmensons. Its most common uses
are as follows: It can be used for dranng domestc waste water collectors, ran water
collectors, n flooded envronments, and n the excavatons and pts of the constructon
ndustry (EFP 26 DV or EFP 26 DT may be used). Vortex pallet models are also sutable for
the transfer of lquds that contan suspended flament materals.
3. Usage Lmts
EN 60335-2-41 standard prohbts usng the pump n tanks or swmmng pools that contan
people, and oblgates the use of the versons wth a 10m cable for outdoor use.
Pump workng condtons are not corresponded these flud propertes;
• Flud s over 35°C temperature, over 1000 kg/m3densty, over 1mm2/s knematc vscosty
• Chemcals that may be harmful to the pump materal and fluds contanng solds larger

4. Electrcal Connecton
The pumps must be used wth an ETNA Hydropan electrcal panel.
5. Control of the Drecton of Rotaton
The correct drecton of rotaton s clockwse when lookng at the pump from above.
Observe and check the pump performance. Wth the correct drecton of rotaton, hgh
Q/H performance s ensured wth sngle channel and double channel versons, and a low
absorpton rate s provded wth vortex wheeled versons.
6. Mantenance
Please make sure that you power o f any mantenance s requred on the pump and call an expert
for the mantenance operaton.
The pump does not requre any routne mantenance. Cleanng the sucton flter (EFP 22D, EFP 26DV)
or the wheel may be requred. Remove the screws that hold the flters to access the wheel on the
models wth flters.
7. Safety Informaton
• The pump s not sutable for pumpng flammable or dangerous lquds.
• Do not use the energy cable to carry or lft your pump.
• Do not run the pump dry (out of the water).
• Snce the pump runs and stops automatcally, do not put your hands or other objects n
between when t s connected to the mans.
• Pay attenton to the lmtatons of use. Inapproprate use may damage the pump or
people.
• Ensure that the network voltage conforms to the value on the label.
• If the pump s three-phase, have the connectons to the electrc grd and the earthng
socket conducted by an expert (authorzed electrcan).
• Use a senstve phase relay (0.03A) as extra protecton aganst electrc shocks.
• Restrct the access of ndvduals, who are not authorzed to mantan the pump.
• Use the pump wthn the usage lmts defned on the label.
• Protect the pump aganst freezng.
• Protect the pump aganst potental blockages.
• We recommend that you wear gloves durng any acton conducted on the pump.

Fxed Installaton wth Sledge (Fgure 2)
• Fx the bottom secton of the sledge to the tank base as shown.
• Cut two 3/4" stanless ppes accordng to the dstance between the top secton of the
sledge and the fxed secton of the sledge and nstall (Fgure 4, Fgure 5).
• Mount the pump sledge flange and the connecton parts (Fgure 6). Attach a chan or a
rope to the handlng rng of the pump, slde the pump downwards from the sledge and
place t on the bottom part of the sledge.
• Connect the check valve and the valve to the horzontal secton n order to facltate access
to the dscharge ppe.
• Ths wll enable pump mantenance whle keepng the dscharge ppe connected to the
nstallaton
8. Troubleshootng
The motor starts runnng but the pump does not transfer: Make sure that water level s not
very low and the sucton nozzle or the dscharge ppe s not clogged.
If the transfer of the pump s reduced: Check for blockages and check the accuracy of the
rotaton drecton on the three-phase models.
If the pump runs ntermttently:
- The floater swtch adjusted wrong.
- The contaner of the pump s very small.
- The current wthdrawn from the electrcal panel s hgh.
- The pump or the ppes are clogged.
9. Nose
If the pump runs partally under water, the nose level should be less than 70 db(A), but ths
value s not applcable when the pump runs completely under water.
10. Installaton
The nner dameters and the szes of the ppes should allow flow. The water speed should be
hgher than 0.8-1m/sec n horzontal ppes, 1.6.m/sec n case of sand and floatng substances
and hgher than 2.5m/sec n vertcal ppes to prevent any possble blockage. The dscharge
ppe should never be smaller than the pump dscharge dameter. The vertcal ppe sectons
should be lmted and the horzontal ppe sectons should be slghtly nclned n the drecton
of the flow to prevent any depost that may cause the pump to stop.
The pump should be held from ts handlng rng whle beng lfted or moved, and never be
lfted from ts cables snce ths may damage the pump. (Fgure 1) The maxmum mmerson
dept (ncludng the cable) should be 5m for EFP 11 and 10m for EFP 22 and EFP26.

Moble Installaton (Fgure 3)
• Prefer a chan or a rope that wll not rot, and connect t to the handlng rng of the pump. Always use
a chan or a rope to lower, lft or move the pump f you have a plastc or flexble dscharge ppe. Never
pull out from the power cable because t wll damage the pump. Connect the power cable to the
lftng chan or the rope usng proper connectors. Leave a sucent space for the cable to move snce
there wll be extra weght when the pump runs n case of a flexble dscharge ppe.

Immerson Sledge Installaton
• The mmerson sledge s a fttng that provdes ease of nstallaton and mantenance n
cases where the pump s requred to run on a fxed pont. As seen on Fgure 12 and Fgure
13, thanks to ts sledge system, the pump s easly suspended nto a well usng a chan
through ts stanless steel gude ppes and when t s drectly across from the flange located
at the bottom of the sledge, t sts onto the dscharge flange, and s ready for operaton.
Dscharge of the chamber, where the pump s located, s not requred durng ths process.
When mantenance for the pump s desred to be carred out, the pump s pulled up usng
a chan, cleaned by sprayng clean water wth a hose, easly taken out, and ts mantenance
s carred out. The pump s lowered back nto the well on the sledge after mantenance
and wll be easly made ready for operaton. It s recommended to use a strong chan when
suspendng the pump down on the sledge.
