FlowCon SM Weather Box 1A95120 - 02/2023 Installation and Operation Instruction The FlowCon SM Weather Box can be added to any SM valve size: - DN15-250 (1/2”-10”) and is available with the FlowCon actuators: - SM.0.0.0.3 (standard) - SM.0.0.0.4 (standard failsafe) - SM.0.0.0.6 (BACnet failsafe). Spindle adaptor Snap ring The bottom side of the actuator Figure 2 “Actuator legs” Snap ring: Stop points Figure 3 Figure 1 Fitting and Re-fitting the weather box including actuator It is recommended to grease the O-ring on the spindle adaptor with silicone grease before plac- ing the spindle adaptor on the valve spindle. Then place the weather box including actuator on the spindle adaptor and place the three ac- tuator “legs” into the three holes in the mounting bracket (figure 2 and 3). Make sure that the snap ring is clicked onto the mounting bracket, so that the snap ring is locked at the top of the mounting bracket, but still able to rotate. Then finger- turn the snap ring counter clockwise (upside view) approximately 1/6 of a turn until its stop points touch the actuator “legs” and the mount- ing is locked with a (small) click. Do not use ad- ditional tools. Orientation Install the valve so that the weather box with ac- tuator is located upwards and not lower than the horizontal line in order to guarantee the higher IP rating. -90° to +90° Figure 4 This paper is a supplement to the FlowCon General Instruction Latest release of any FlowCon material is available on www.flowcon.com Page 1 of 2
