Electrical:
Aqualified electrician incompliancewithstandardsandlocal codesshoulddoall electrical
wiring.Besure toinvestigatethelocal requirements before installingthe compressor.
Thepowersupplyshouldbe adequateandfreeofparasitic loads that will causean under

2.3GuidelinesforCompressorAirSystem:
The airpressuredrop betweenthecompressor and thepoint of useis not recoverable.
Pipe Sizeshouldbelargeenoughthatthepressuredrop doesnot exceed10%between
theairreceiver andthepointofuse. Generallykeep thecompressedflowataround1500 –
2250feet/minutevelocity.
Arrangethe airdistributionpipe toavoidthe followingtypesoffstrains:
1.Strains that is duetothe deadweightifthepipeitself.
2.Strains that is duetoexpansion or contraction ofthepipe duetotemperature.
3.Strainsdue tointernalpressure withinthepipe.
Designinlet and dischargepiping for smoothairflow.
Planforfutureemergenciesand establishanareaofthe looptoinstallatemporary
compressor.
Consider bypass linesaround allitemsthatmayrequirefuturemaintenance.
Useloop-pipe systemsifpossible,botharound the plant andwithinworeareas.
Consider asecondreceiverat the endofthe lineor oppositesideoftheloop.
Locaterunsawayfromthemainheader closetothe point of application.Thislimits the
pressuredropthroughhose.
Takeairoffthe top oftheheader topreventcarryover ofcondensedmoisturetotools.
Slopepipesothatit drains towardadrop letor moisture trapawayfromthe compressor.
2.4UnpackingandHandling:
Occasionallydamagewilloccur duringshipping. Besure tocarefully inspect theunit before
unpackingand after unpacking beforeyou signthereceiver.Ifanyhas occurred,document it
withthe truckingfirmimmediately.Contact you LaPlanterepresentativefor assistance.
Tomoveyour compressor toits installation site, werecommendthatyouleavetheunit onits
shippingskidas longas possible.Theforks shouldbeextended the widthofthe compressor
andpadding shouldbeplaced betweenthecompressorandthefork truck boom.
If itis necessarytoliftthecompressorwithacrane, werecommendtheuseofspreaderbar
andchains. The spreaderbarshouldbe greater than thewidthof thecompressor and padding
placed onthe edges topreventchaindamage.
ProcedureforHandling DamagedShipments:
1.The customer, at thereceivingpoint, MUST inspecteachshipmentfordamage.
2.Ifthe shipmentis damaged,thecustomer shouldsonoteitonthefreight bill.
3.The customer shouldrequest an inspectorfromthe freight companytoinspect theequipment

immediately.It is best to senda confirming letterwith the following information:
a.Freightbillnumber.
b.Datedelivered -shipper's name&address.
c.Description ofitem(s)damaged.
d.Description ofdamage(a Polaroidpictureifpossible).
e.Acopyofyourinvoicefortheequipment.
4.After inspection,(beforetheinspector leaves):
a.Get acopyoftheinspectionreport.
b.Request theunit be shippedback "free astray".
c.Request acredit fortheoriginalfreight bill.
5.Callthefactoryand:
a.Get aReturnMaterialAuthorization(RMAnumber).
b.Give a purchaseorder for repair.The purchaseorder shouldrefer tothe item
and
trucker claim.
6.Wewill accepttheshipmentback, repair(undernormalconditions)and return it within(7)
sevenworkingdays.
7.Wewillinvoicethe customer for therepair,whichwill then becomepart ofyour claim.The
invoicemust be presentedtothe truckingclaimdepartment alongwiththeirclaimform.
8.Wesuggest ifthetruckerdoes notpaywithin30 days that youcall and/orwritetheICC
making a formalcomplaint of poor service. AlsoadviseLaPlanteCompressorLtd. in
writing for follow-up.
Ifdamage canberepairedatthereceiving point, followProcedure1,steps1through
4a.Repairtheunitand makeoutadetailed invoicetothe trucker showinglabor hours,
laborrate, materials used,and cost of materials.
2.5Storage
Insomecasesitmaynecessarytostorethe compressorfor extendedperiodsofseveral
months beforeplacing theunitinoperation. When this is requireddothe following:
1.Coverandsealall machineopeningstoprevent theentranceof wateranddirt.
2.Coverall openings inopendripproofmotors topreventtheentranceofrodents.
3.Ifthestorageconditions arebelowfreezing,drainoffthe aftercooler, traps, water-cooled
heat exchangersandrelativepiping. Wedonot recommendoutside storage.
4.Cover withawaterprooftarpaulinthatcan easilybe removed for instorage maintenance.
5.Whileinstorage,everytwoto three monthsrotatethe compressorandmotorbyhand to
preventflat spots onthebearings thatwillleadtopremature failure.
Attheend of the storageperiod,followthe uncratingand start-upprocedures.If the unit has
been stored for more thaneighteen monthsyoushouldcontactLaPlanteCompressor Ltd.
beforecommissioningthecompressor.
2.6InstallationDrawings(Recommended):
Aminimumdistancefromwalls, other machines, etc.shouldbe maintained sothatthereis
sufficient clearancefor maintenanceand repairwork(refer tofigure2-2).
Werecommendaminimumduct cross-sectionofapprox. 0.3 squaremeter.Inorder toensure
agoodheatdissipation,auxiliaryfans shouldberatedtoprocess approximately15-20%more

4.0:CONTROLLER
4.1Introduction:
Ingeneral,the controllerhas following functions:
lControllingthecompressor
lProtectingthecompressor
lMonitoringcomponents subject toservice
lAutomatic restart aftervoltagefailure
AutomaticControlof theCompressor
Thecontroller maintainsthenetpressurebetweenprogrammablelimitsbyautomatically
loadingand unloadingthecompressor.Anumber ofprogrammablesettinge.g.the
unloadingandloadingpressures,theminimumstoptimeandthemaximumnumber of
motor starts aretaken intoaccount.
Thecontroller stopsthecompressor whenever possibletoreducethepower consumption
andrestarts it automaticallywhenthenetpressure decreases.
Protectingthecompressor
