Installtheunitinafreshandwellvenlatedplace.Mountthepanelonthewallusingthesupportsonits
back.Thepanelshouldimperavelybemountedupright.

Keep any acid tanks away from the room where the unit has been installed. Acid vapours aack
metals including stainless steal and destroy electronic circuits.
Keep the top of the panel and the heat sink area clear of any objects.

thecellisinstalledvercally,thewatermustenterthecellthroughtheboominlet.


Do not install the cell before the filter or any other element. The chlorinator cell must be the last ele‐
ment the water passes through before returning to the pool. Otherwise the gas generated in the cell
could build up in the circuit and cause an explosion.

Flow switch
Install the flow switch preferably downstream. Install the T‐fing horizontally so that, once installed, the
flow switch will stand vercally. If you cannot install the switch vercally make sure the arrow points up
NEVERDOWN.BeforeghtentheflowswitchverifythattheOringisonitshousingandthatthearrow

5. PUMP COMISSIONING
Verify that the locking cell rings are properly installed before starng the pump. Press the rings out‐
wards along their enre length to make sure they are enrely inserted in the slots .

When water is being injected into the cell, make sure that there aren’t any CLOSED VALVES down‐
stream because the pressure generated will break the cell housing. Similarly, NEVER CLOSE any
valves downstream when the pump is running.


Rev.15‐03‐20177
Beforestarngthepumpforthefirstme,openthecentralby‐passvalvefullytoavoidanyoverpressurein

thewaterflowaerreghtening.
6. ELECTRICAL CONNECTIONS
Power supply cable
Thechlorinatormustbepoweredto230VAC.Connectthethree‐wirepowersupplycable(marked“230VAC
powersupply”)toapermanent230VACmainspowersupplywithprotecveearth.Thevoltageonthiscable
mustbekeepconstantaslongasthechlorinatorisinuse.DO NOT INTERRUPT the power on this cable
alongthepumpworkingcyclesorbymeansofanyothercontroldevice.Inordertocontrolthechlorinator
produconcyclesusetheExternal Control Cable.Disconnectthepowersupplyonlywhenyouarenotgoing
tousethechlorinatororincaseoffault.

The chlorinator must imperavely be connected to a protecve earth through its power supply cable
and protected by a 30 mA residual circuit breaker.
External Control Cable
Thetwo‐wirecablemarked“EXTERNAL CONTROL 230VAC”isusedtostartandstopthechlorineproducon
synchronicallywiththepumpworkingcyclesorbymeansofacontroldevice.Whenthevoltageappliedbe‐
tweenthetwowiresis230VACthechlorinatorwillproducechlorine.Whenthevoltagebetweenthewiresis
0VACthechlorinatorwillhaltthechlorineproduconandenterapausemode.Therefore,thevoltageap‐
pliedtothecontrolcablemustbedrivenbythesamemeans,signalordevicethatpowersorcontrolsthe
pump.
Make sure that the voltage applied to the External Control Cable is 230VAC ONLY when the pump is
running and the water flows freely through the cells and to the pool.
6. OPERATION
TheSMC50‐75celliscontrolledbymeansofakeyboardandadisplay.Inaelectrolyccell,chlorinegenera‐
onisproporonaltotheelectricalcurrentflowingthroughit.TheSMC50‐75willtrytomaintainaconstant
electricalcurrentinthecellaccordingtothechlorineproduconrate(0—100%)setbytheuser.Thevalues
ofcurrentandvoltageinthecellareconstantlydisplayedinthemainscreen.Innormalcondionsandat

9. REGULAR MAINTENANCE
TheSMC50‐75requiresaminimalmaintenancethatisbasicallyreducedtotheinspeconandcleaningofthe
cellanditsconnecons.Nevertheless,thisminimalmaintenanceisfundamentalforgoodoperaonandper‐
formanceoftheunitandtoavoidfutureexpensivefailures.

9.1 Cell

Inspectthecellfrequently.Theelectrodesbladesshouldbecleanandfreefromanybuilduporobjects.The
watermustflowrapidlyandwithoutanyobstaclethroughthetubularcelltoavoidcalciumbuildup.Ifyou
observehighturbulencenearthewaterinletsoralowflowspeed,increasethewaterspeedthroughthecell
bysendingmoreflowtocelltheby‐pass(closinggthecentralvalve).Ifthewaterhardnessisveryhigh,even
afastflowwon’tpreventthescalefrombuildingup.Ifthisoccurs decreasethepolarity period andmake
surethewaterpHstayscloseto7.0.

Thepolymersealunderthecellcapandtheprotecvesleevesoftheelectroderodsmustbothbeintact.If
anydamageisobserved,sendthecelltothetechnicalserviceforinspeconandrecondioning.

TheelectrodesoftheSMC75cellhavebeenbuildusingthemostadvancedtechniqueinthemarketandwith
averyhighqualitycontrol.Howeverthereareseveralsituaonsthatcanreducetheperformanceandthe
lifespanofanyelectrodeandyoushouldavoidthem:

  ‐Operaonwithalowwaterlevelorflowinthecell
‐Operaonwithscalebuildupontheelectrodes
‐Frequentacidcleansing
‐WaterpHtoohighortoolow
‐Acidinjeconbeforethecell


9.2 Cell pins
Checkregularlytheconneconareaofthecellandmakesureit’scompletelydryandclean.Turnthe
unitOFFandremovethecellconnectors.Verifythatallthepinsaremoderatelyghten.

Tighten the pins preferably by hand.If you use a wrench, do it very carefully because you could easi‐
ly damage the sealing or the electrodes.

10. WARNINGS










‐ NEVER power the unit without being connected to a protecve earth conductor.
‐ NEVER operate the chlorinator without an external 30 mA residual circuit breaker protecon.
‐NEVERoperate the chlorinator if the pump is not running or if the flow through the cells is too low.
The gas generated in the electrolyc proceeds could break the cell and eventually explode.
‐NEVER install the chlorinator before the filter or any other element. The chlorinator must be the last
element the water passes through before returning to the pool. Otherwise the gas generated in the cell
could build up in the circuit and cause an explosion.
‐ DO NOT access the Programme menu or change any parameter in it.
‐ ALWAYS keep the cell caps, cell terminals, and cell connectors completely dry. Salty water or moisture
will create an electrolyc process and corrode the connectors rapidly..
‐ ALWAYS keep acid tanks away from the unit room.
