strictaccordancewiththeinstructionsissuedatthattime.
Unitswithoptionalfactory-furnishedandinstalled
aquastatsmaybeshippedwiththeaquastatsmountedon
acoilstub-out.Removetheaquastatbeforeinstallationof
avalvepackage.Consultthefactorypipingdiagraminthe
approvedsubmittalsforproperlocationwhenreinstalling
theaquastats.Ifthevalvepackageiseld-furnished,the
aquastatmustbeinstalledinalocationwhereitwillsense
thewatertemperatureregardlessofcontrolvalveposition.
Ableedbypassmayberequiredtoguaranteeproper
aquastatoperation.
Alleldwiringshouldbedoneinaccordancewith

Exposed Unit Touch-up and Repainting
Exposedcabinetunitsmaybefurnishedwithabaked
enamelnish.Smallscratchesinthisnishmaybe
repairedwithtouch-uppaintavailablefromthefactory.
Somecolorsoftouch-uppaintareavailableinaerosol
containersandalltouch-uppaintisavailableinpint,quart,
andgalloncans.Contactthefactoryforavailability.
Propersafetyproceduresshouldbefollowedregarding
ventilationandsafetyequipment.Themanufacturer’s
directionsshouldbefollowedfortheproductsbeingused.
Torepaintthefactory-bakedenamel,thenishshouldbe
preparedbylightsandingwith#280gritsandpaper,or
#000or#0000nesteelwool.Thesurfacemayalsobe
wipedwithaliquidsurfaceetchcleaningproductsuchas
“NoSand”or“Pasceo.”Theseitemsshouldbeavailable
atmostpaintproductstores.Itshouldbenotedthatthe
moreconscientiouslythispreparationisdone,themore
effectiveitwillbe.
Afterthispreparationisaccomplished,thefactorynish
shouldprovideexcellentadhesionforavarietyofair-dried
topcoats.Enamelwillgiveamoredurable,highergloss
nish,whilelatexwillnotadhereaswellandwillgive
adull,softernish.Topcoatsinvolvinganexothermic
chemicalprocessbetweentwocomponents,suchas
epoxiesandurethanes,shouldbeavoided.
Factoryaerosoltouch-uppaintmayrequireanumber
oflight“dustcoats”toisolatethefactory-bakedenamel
nishfromthequickdryingtouch-uppaint.
