FlowCon SM DN15-250 (1/2”-10”) 1A95106 - 11/2023 Installation and Operation Instruction The FlowCon SM are available in two different double union end connected models covering five different sizes and four different flanged models covering nine different sizes: FlowCon SM.1 DN15-25 (1/2”-1”) FlowCon SM.2 DN25-40 (1”-1½”) FlowCon SM.3 DN50-80 (2”-3”) FlowCon SM.4 DN80-100 (3”-4”) FlowCon SM.5 DN125-150 (5”-6”) FlowCon SM.6 DN200-250 (8”-10”) DN 25/32/40 The actuator types FlowCon SM.0.0.0.3, SM.0.0.0.4 and SM.0.0.0.6 are electrical pro- grammable actuators. SM.0.0.0.6 is a BACnet actuator and has a supplementary instruction on BACnet connection and programming. Fitting and Re-fitting the 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 actuator on the spindle adaptor and place the three actuator “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 mounting is lock with a (small) click. Do not use additional tools. O-rings are supplied with the valve body and are used to seal the connections. It is recommended to grease the O-rings with silicone grease. Please make sure these are properly placed in the O-ring grooves on valve inlet and outlet, before installing the housing. Please note that FlowCon SM.6 (DN200-250 / 8”-10”) contains two O-ring grooves. Use the inner groove for DN200 / 8” flanges and outer groove for DN250 / 10” flanges.
