INSTALLATION
PROPERINSTALLATIONISIMPORTANT.IFYOUNEEDASSISTANCE,CONSULTACONTRACTOR,ELECTRICIAN
ORTELEVISIONANTENNAINSTALLER(CHECKWITHYOURLOCALBUILDINGSUPPLY,ORHARDWARESTORE
FORREFERRALS).TOPROMOTECONFIDENCE,PERFORMA TRIALWIRINGBEFOREINSTALLATION.
Whenconnectingthewinddirectionsensor
totheZ-mast,makecertainthatterminal#4
isalignedwiththeZ-mastarm. Ifthesensor
isnotinstalledinthismanneryourwind
directionreadingswillbeincorrect.
Slidethestubmaststhroughtherubberbootsand
insertthestubmastsintothebottomofthesensors.Secure
withthecotterpins. Coatallwireconnectionswithsilicone
sealantandslipthebootsoverthesensors.
