2.5 Operating conditions
Incaseofextremevariationsinambienttemperatureandhighhumiditylevels,installationofa
heatingresistorisrecommendedtominimisecondensationintheactuator.
Actuatorcoverswithsuppressionofthermalbridges(dualcovers)arerecommended.
● Connecttheheatingelement(HZG)asshowninthewiringdiagram.
● Putthedeviceintoserviceassoonasitisinstalled.
Theactuatorsaresuitableforinstallationinindustrialplantsandinwaterworksandpower
plantswithalowpollutantconcentration.
Foruseoutdoorsorinanenvironmentwithahighpollutantconcentration,suchasheavytrafc
areas,industrialareas(chemicalplants,sewageplants,etc.),coastalareasandtheopensea,
theactuatorsmusthaveexternalpartsmadeofnon-corrosivematerialandmustbeprovided
withaspecialcoating.
Whenusedoutdoors,theactuatormustbeprotectedwithanadditionalcoveragainst
● rain
● directsunlight
● strongdraughts
● dust
3. TRANSPORT AND STORAGE
Risk of injury caused by failure to observe safety regulations!
Caution
● Weartherequiredpersonalandotherprotectiveequipment.
● Protectthelinearactuatorfromimpact,shock,vibrationandsimilarinuences.
● Storethelinearactuator(orthecompleteactuator/valveassembly)inadryplace.
● Observethetransportandstoragetemperaturelimitsof-20to+60°C.
