“Vapac Steam Humidifier”. Essentially they consist of a stainless steel manifold, and a number of axial fans contained in a metal box. The steam manifold distributes the steam evenly across the face of the fans, which blow air over the plumes of steam, in order that the steam is absorbed quickly into the conditioned space. Prior to Installing the Vapac Unit & RDU. • Check that the unit and RDU installation complies with the minimum dimension requirements shown in Figure 1 and Table 1 below. Table 1. RDU Output (kg/h) Minimum Distance to Ceiling 0 – 5 kg/h 200 mm 5 – 10 kg/h 250 mm 10 – 30 kg/h 500 mm 30 – 45 kg/h 750 mm Min. height (See Table 1) Min. 300 mm Min. 80 mm Min. 1000 mm Access 1000 - 1200 Recommended Height Figure 1

• Unpack the RDU, ensuring that all parts/documents are removed prior to discarding the packaging. • Remove the RDU cover by removing the six screws – 3 each side – and lifting the cover clear. • Place the RDU on top of the Vapac Unit, so that the steam outlet of the unt and the steam inlet of the RDU are aligned. • Check the position of all other inlet / outlets from / to the unit / RDU, noting any blanking plugs / knockouts, which need to be removed. • Remove the RDU from the unit – remove the blanking plugs / knockouts as necessary. • Re-place the RDU on the unit. • Secure the RDU in place uning the fixings supplied. • Connect the steam hose between the cylinder outlet and the RDU steam inlet, securing each end with the hose clips provided. • Connect the condensate hose to the two condensate drain points of the steam heder, “Tee” these together using one of the nylon – T’s provided – (see Fig. 2). The second nylon – T should be used to connect the combined condensate drain into the feed line between the “tundish fill cup” and the feed drain manifold – approximately 1/3 of the way up from the manifold – (see Fig. 2). • Connect the electrical supply to the fans, 230 V~ live from terminal 25, and 230 ~ neutral from terminal 26. The earth should be connected between the RDU (earth stud) and Unit (earth rail). • Replace the RDU cover, and secure in place with the six screws removed earlier. Figure 2
