3 BASIC SAFETY INSTRUCTIONS
Thesesafetyinstructionsdonottakeintoaccountanyunforeseen
circumstancesandeventswhichoccurduringinstallation,operation
andmaintenance. The operator is responsiblefor observingthe
location-specicsafetyregulations,alsowithreferencetopersonnel.
Risk of injury from high pressure.
▶Beforeworkingonthedeviceorsystem,switchothepressure
and vent or empty the lines.
Danger of burns and risk of re.
Followinganextendeddutycycleorasaresultofahotmedium,
thesurfaceofthedevicemaybecomehot.
▶Only touch the device when wearing protective gloves.
▶Keepthedeviceawayfromhighlyammablesubstancesand
media.
Risk of crushing by mechanically powered parts.
▶Installationworkontheswivelplate,diaphragmandvalvebody
mustonlybeperformedwhileelectricallyisolated.
▶FordeviceswithSAFEPOSenergy-packs:Ensurethatthe
SAFEPOSenergy-packisfullydischarged.Waituntilthe
LEDringisnolongerlitandensurethattheLEDstatusisnot

7 INSTALLING THE VALVE
7.1 Safety instructions
WARNING!
Risk of injury due to improper installation.
▶Installation may be carried out by trained technicians only with
the appropriate tools.
▶Secure the system against unintentional activation.
▶Afterinstallation,ensurethattheprocessisrestartedinacon-
trolled manner. Observe the sequence.
1. Connect supply voltage.
2. Charge the device with medium.
CAUTION!
Risk of injury due to heavy device.
Duringtransportationorinstallationwork,thedevicemayfall
down and cause injuries.
▶Transport,installandremoveheavydevicewiththeaid
ofasecondpersononly.
▶Usesuitabletools.
NOTE!
The following must be heeded when installing the device
inthe system.
Thedeviceandreliefboremustbeaccessibleforinspections
and maintenance work.
NOTE!
Damage to valve body, seat seal or diaphragm.
▶Topreventdamage,thedevicemustbeinMANUALoperating
state during installation.
Devicesintheirfactorydefaultstatealreadyhavetheiroperat-
ingstatesettoMANUAL.

DANGER!
Risk of injury from high pressure.
▶Beforeworkingonthesystem,switchothepressureandvent
or empty the lines.
WARNING!
Risk of crushing by mechanically powered parts.
▶Donotreachintotheopeningsofthevalvebody.
→Connect valve body to pipeline.
Ensure that there is no voltage present and minimal
vibration during installation.
Holding device
Toprotectthevalveactuatorfromdamageresulting
fromforcesandvibrations,aholdingdeviceisrecom-
mended. This is available as an accessory. See oper-
ating instructions on the website
country.burkert.com
7.3 Installation of devices with welded
connections
The device must not be welded into the pipeline while the actuator
isstillinstalled.Theinstallationisdividedintothefollowingsteps:
1.Preparetheactuatordisassembly.
2. Disassemble the actuator.
3. Weld the valve body into the pipeline.
4.Mountingactuatoronthevalvebody.
7.3.1 Prepare the actuator disassembly
NOTE!
Damage to valve body, seat seal or diaphragm.
Toavoiddamage,thevalvemustbeopenwhentheactuator
isdisassembled.
→Ifthevalveisclosed:Openthevalvewiththemechanical
manual override. See chapter “12.2 Actuating the valve
mechanically” on page 39.

▶Donotreachintotheopeningsofthevalvebody.
7.3.2 Disassemble actuator
→Clamp valve body into a holding device.
→Placeonthebodyconnectionwithasuitableopen-end
wrench.
Donotuseanytoolsforunscrewing,whichcoulddamage
thebodyconnection(e.g.pipewrench).
