SAFETY
• Alwaysfollowlabelinstructionsforthechemicalyouareusing.
• Toavoiddangeroffireorexplosion,donotfogflammableliquids,
 especiallyinanenclosedarea.
• Wear a mask or respirator as required by the chemical being
 applied. Fog particles can be practically invisible and are easily
 inhaled.
• Donotfogsomuchthatfogparticlesaredrawnbackintounitin
 theintakeair.Keepairfilterinplace.
THEORY OF OPERATION
SentinelIIfogheadsuseapowerfultangentialblowertoatomizefeedliquid
inturbulentmixingnozzles.Thefogheaddrawsairthroughanintakeporton
topoftheunit.Thisallowstheunittobeusedindirtyhostleenvironments.
A pressure switch in the fog head controls its operation.When the switch
senses a pressure of at least 3 psi at the liquid feed inlet, it turns on the
blowerandopensasolenoidvalveallowingliquidtoflowthroughametering
valveandintothenozzle.
TheSentinelII5700headletsyouadjustfogdropletsize.Atthefineendof
therangearedropletsof7-10micronsVMD(volumemeandiameter).Such
droplets,whicharepracticallyinvisibleexceptunderoptimallightingcondi-
tions,formalightdryfogwhichfloatsalongtimeanddiffuseswidely.
Thehighendofthenormalrangeisdropletsofabout30micronsVMD.These
formaheavymistwhichsettlesquicklytowetsurfaces.
Fogheadsoperatebestata5-15psiliquidinletpressure.Thisprovidesample
liquidflowtonozzlesyetallowsgoodcontrolbythemeteringvalve.Higher
pressuresmakeithardertoadjustdropletsizeandincreasethechancesof
impuritiesobstructingthemeteringvalve.
Ifexcesspressureisaproblem,installanin-linepressurereducerintheliquid
lineorapressurecontrolledbypassloopattheliquidpump.
Pressure Control Techniques

SENTINELII57003
Bank of foggers controlled by turning supply
pump on and off, under timer control.
Pressurized liquid source, such as the house water
supply, feeding a zone of foggers. Solenoid valve
is controlled by repeat cycle timer.
Fog heads controlled individually by solenoid
valves in supply lines. Chemicals can be injected
“in-line” with a proportioning injector. Valves
controlled by multiple timers.
INSTALLATION PLANNING
ASentinelIIinstallationcancontainanynumberoffogheads,allsupplied
withliquidfromacentralsource.Thiscanbelocatedwhereverconvenient.
Iffoggingchemicalsmustbediluted,youcanuseamixingreservoirorinject
themin-linewithaproportionalmixer.Lowpressuretubingorotherlowcost
materialisusedtoconnectheadstotheliquidsource.
Headscanbeoperatedindividuallyorconnectedtogetherinzones.Nozzles
canberotatedtoanydischargeangle.Ameteringvalveoneachhead(open
counterclockwise for more flow, larger droplets) is used to set fog proper-
ties.
Power requirements, piping sizes and valving are determined by the head
layoutandexpected liquidflows.Eachhead draws10A at120VAC(5Aat
240V).Ahead’seffectiverange(instillair)is75-100ftforsmalldroplets,and
30-60ftforlargerones.Liquidoutputis4-10oz/minforsmalldroplets,and
10-20oz/minforlarge.
System Control
Whentheinletpressureatthefogheadexceeds3psi,thepressureswitch
turnsontheheadandgeneratesfog.Tocontrolanindividualhead,feedit
separately.To control several heads at once, connect them to a common
liquidline.
Manyinstallationsuserepeatcycletimerstoactivatesolenoidvalvesorlow
pressuretransferpumps(seeexamplesbelow).

Fog Droplet Size
Itisimportanttoadjustfogdropletsizeproperlyforyourapplication.Larger
dropletsarebetterfordustcontrol,humidificationandsanitizing.However,
large droplets settle faster, and heads must be closer together to get even
coverage.
Smallparticlesarebetterforsuch“airmix”applicationsasodorcontroland
ULV (ultra low volume) pest control; they float extensively, have a large
surfaceareaandevaporatequickly.
Ameteringvalve(drawing,p.5)controlsthedropletsizeofeachhead’sout-
put.Closethevalve(turnclockwise)forsmallerdroplets.Toohighapressure
intheliquidfeedlinewillmakeithardertoadjustforsmallerdropletsizes.
Installastep-downpressureregulator (see“Theoryof Operation”)to solve
thisproblem.
“Fine-Tuning” The System
Someexperimentationisusuallyneededtoobtainbestresultsatthelowest
operatingcost.Thistypicallyinvolvesthreefactors:
1. Head Location.Fogheadsshouldbeplacedwheretheyareneeded,and
spacedforuniformcoverage.Tomoveahead,oraddanewone,justmount
itwhereneeded,plugintoanelectricoutlet,andattachaliquidfeedline.
2. Droplet Size.Werecommendstartingwithalargedropletsize,thenmov-
ingtosmallerdropletsasneededtoincreasediffusionandpenetration,orto
reducewettingandfallout.
3. Fog Cycle Time.Mostfoginstallationsrunintermittantly,usinganinterval
timer to turn on a liquid feed pump or activate a solenoid valve. After
determininganeffectivedropletsize,graduallyshortentheONcycletime(or
lengthentheOFFcycletime)toreduceliquidconsumptionandmotorwear.
Keep reducing fog output until you find the point of maximum control at
minimumcost.Youmayhavetoadjustfoggingcycletimestocompensatefor
seasonaltemperaturechanges.
CONTINUOUS OPERATION
Ifyourfoggingsystemmustoperatecontinuously,usethesmallest
dropletsizethat doesthe job.Thiswill minimizeliquiddischarge
andchemicalexpense.
Be aware that continuous operation means faster wear on motor
brushes.(Typicalbrushlifeis650–700hours—aboutonemonthat
24hoursaday,7daysaweek.)
