T3 Control Set Installation Guide 1. General 1.1 This T3 control set has been designed for control of flow and water temperature in an underfloor heating system. It is pre- assembled and tested to ensure that it can be fitted with the minimum of on-site labour and commissioned immediately once fitted. 1.2 As supplied it is designed to connect to the left hand side of an Emmeti manifold with 210mm between the centres of the flow and return arms. It can also be used with any other manifold built on this dimension. The control set can also be altered to fit to the right hand side of a manifold simply by removing the bracket clips and turning the control set elbows through 180 degrees using the union fittings at the top and bottom of the pump. The pump motor may need to be rotated through 180 degrees to minimise the space occupied by the control set and allow access to the electrical connection box. Maximum static pressure 10 bar Maximum differential pressure 3 bar Maximum temperature 95oC Operating temperature Range Adjustable between 35oC and 60oC Inlet connections 2 x 1”M (G1) Outlet connections 2 x 1” M (G1) – swivel joint Overall dimensions mm 311h x 189w x 132h Kvs 3.4 65 39 2.

Installation 5.1 Remove the control set assembly carefully from the packaging and check to ensure that all components are in place and that there is no damage to them. 5.2 The control set is supplied for connection to the left hand side of the manifold but can be altered very simply for connection to the right hand side. (i) Remove the mounting bracket clips from the control set by unscrewing the two screws shown in Fig. 3 and rotating the upper and lower elbows through 180o using the pump union nuts. 5.3 Re-fit the mounting bracket and rotate the pump to an upright position as shown in Fig. 4. Fig. 3 Remove mounting bracket clips Fig. 4 Re-fit mounting bracket 5.4 If the pump needs to be lowered into the gap in the mounting bracket for space-saving reasons, it will be necessary to remove the Allen screws securing the pump motor and rotate the motor so that the junction box is at the front. 5.5 The control set can be attached to the manifold either before or after the manifold is secured to the wall. The control set should be secured to a flat vertical surface able to support the weight of the control set and manifold. Using the dimensions shown in Figs. 1 and 2, ensure that there is sufficient space for installation and maintenance at the intended position for the control set. The fixing hole positions of the mounting bracket can be marked through the mounting bracket itself. 5.6 A swivel joint is fitted to each side of the control set for connecting to the 1” F manifold tappings. The inlet tee swivel joint should be connected to the return rail and the outlet elbow swivel joint to the flow rail of the manifold. Carefully offer up and screw the swivel joint threads evenly into the manifold using a 37mm A/F spanner: the use of a 31mm A/F spanner will also ensure that the connection to the control set is kept tight – see 65 39
