DESCRIPTION
Mainfeatures:
−Stainless steelbodyAISI 304 and chapa galvanizada.
−Anti-blocking spraynozzles.
−Pumpwithout seals.
−High pressuresafetypressostatseven inair-cooled machine.
−Large condensers(workwell athigh ambienttemperatures;and reducecooling water
consumption inwater-cooled machines).
−TRANSPARENTCUBES withmost of the watermains.

-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.

-At thispoint the following areconnected:

-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

INSTALLATION
Requiredconditionsforplacementofunit
IMPORTANT:
The NGmachinesareintended toworkatroomtemperaturebetween 5ºCand 43ºC
and withwatertemperaturebetween 5ºCand 35ºC.
Difficultiesduring harvestcyclecan appearbelowtheseminimumtemperatures.
Abovethe maximumtemperaturesthe lifeofthe compressorbecomesshorterand the
production decreasesconsiderably.
IMPORTANT:
The newbox-type frameinNGmodelsallowsabetterventilation inthe air-cooled
machines,due tothe factthatthe condensersareplaced inoblique position inthe front
part of the machine.
The machineswill workproperlyeven iftheyarelocated inplaceswithlittle
ventilation at the rearand lateralsides. The airisexpelled bythe front grill.
Bearinmind the previousremarks ifthe premiseswherethe machine islocated isvery
dustyorsmoky
The flooron whichthe machine will be placeshouldbe solidand asleveled as
possible.
Waterand drainage
Waterqualityinfluenceson icehardness, flavour, and qualityaswell ascondenserlife.
Keep inmind the following points:
a)WATERIMPURITIES:
Majorimpuritiesareeliminated byfiltersprovided. Filtersshouldbe cleaned
regularlydepending on purityofwater.Forminorimpuritieswerecommend installing a5-
micron filter(Provided withthe unit:. Part #ITV7499).

19
b)WATERWITHMORETHAN1000 PPM:
Icewill be less hardand tend toadhere. Cubeswithwhitespotsmayappear. Limedeposits
mayimpede properfunctioning.Inwatercooled models,condenserobstruction islikely.
Installation ofahigh qualitywatersoftenerisrecommended.Limedepositscan be avoided
withthe installation of ourpolyphosphatesfilter. (Part #ITV7500).
c)CHLORINATEDWATER:
Chlorine tastecan be avoided byinstalling acarbon filter(Part #ITV7509).
(NOTE: You mayencounterwaterwithall aforementioned properties.)
d)HIGHT-PURITYWATER:
Upto10%reduction inoverall production mayoccur.
