Have a qualifi ed licensed electricianor other individual who has been properly trained in handling live electrical componentsperform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.-08On/Off control7-08Floating Point or On/Off controlPipingThe valve should be mounted in a weather-protected area in a location that iswithin the ambient limits of the actuator. Allow sufficient room for valve with actuator and for service. Allow 6” for cover removal and 12” for completeactuator removal. The assembly can be mounted with the actuator vertical or horizontal in relation to the pipe. The actuators should never be mounted underneath the valve, as condensation can build up and result in a failure of the actuators. Do not reverse flow direction.LM(B)X24-3-X1, LRX24-3 Actuators, On/Off, Floating PointTech.Doc - 11/14 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
