the microswitchesaredepressed.

-Atthismoment, the compressorisworking;the waterinletvalveand hotgasinlet

valvearebothopen.The waterbinfillswithwater, anyexcess islost viathe maximumlevel

overflow.

-Afteraperiod oftimecontrolled bythe timerthe hotgasvalveand waterinlet valve

areclosed. The pumpthen sendswatertothe evaporatorwherethe icescubesare

graduallyformed. The evaporation temperatureslowlydescendsuntil itreachesapoint

wherethe cyclethermostatisconnected and startsthe timer.Oncethistimehaselapsed,

the defrosting stage (3-4minutes)begins.The pumpisoff and the hotgasand water

valvesareopen. Somewaterissent tothe top of the evaporatortohelpthe cubesunstick.

-Oncethe defrosting stage isover,the cyclebeginsagain,and soitcontinuesuntil

the binisfull ofice,and contactbetween the binthermostatsituated atthe top ofthe bin

and the icewill stop the machine.The binthermostatwill neverstop the machine inmid-

cycle.

press it.

2nd The second switchislocated inthe electricalpanel. Thisone stopsthe condensing unit,

butkeepsthe hydraulicpartinoperation and allowstodo the cleaning ofthe machine

(except inNDP20 model).

terminals.The brownwireconnectsthe compressorand timermotor.The blue wire

-Ared wireconnectsbinthermostatT1and microsG1and G2whichclosethe

circuit with4and provide current viaG1tothe timerG.

-At thispoint the following areconnected:

vWATERINLETVALVE (P)

vTIMERMOTOR(G)

-Sincethe motorofthe timer(G)isworking, during 1÷3minutesthe rolerof microof the

second waterinletcoil (cleaning valvedrive)isdepressed until the pinsreleasethe micro,

closing thisvalve..

-After 2to4minutesmicrosG1and G2will open and closecircuits1-2.

-Viaterminal2on microG2,currentreachesthe pump.Circuit4on microG2which

providescurrenttothe hotgasvalve(Q)and waterinletvalve(P)will be interrupted.Since

the thermostatisbetween 1and 3the timerwill receiveno current. The compressor

continuesswitched on.

-Air-cooled machineshaveafan (R)whichiscontrolled bythe pressostat (F).

-Inwater-cooled modelswithoutpressostaticvalve,pressostat(J)opensand closes

the condenserelectrovalve(K).

-Evaporatortemperaturedecreasesuntil the cyclethermostat(T2)setpointis

reached, at thistemperaturecircuit 1-2will be closed and timermotor(G)will switchon.

-Oncethe cycleisover,the pinson the timerwheelswill forcethe microstochange

circuits,stopping the pumpand opening the hotgasvalveand watervalve.The combined

effectofhotgasand watersprayed on the top ofthe evaporatorwill releasethe icecubes

and change the position of the cyclethermostat (T2).

-The iceproduction and defrosting cyclewill continue until the icestorage binisfull,at

whichpointcyclethermostat(T1)will disconnectthe machine,butneverduring acycle, but

atthe beginning ofthe defrosting stage,sinceduring the production cycle,currentwill

reachthe pumpviaterminals1-2of microG1.

-The machine will remaindisconnected until the leveloficeinthe bindropsbelowthe

thermostatbecauseoficeconsumption.Atthispointthe binthermostatT1changesand

the machine will start anewproduction cycleautomatically.
