Install the heat recovery system in a room protected from frost and high temperatures, ideally in a separate plant room. The following must be available in the place of installation: (1) connections of air channels for fresh air supply and exhaust of used air from/into the outdoor environment (4 ), (2) 230 V mains socket, (3) condensate drain connection. Only remove the packaging from the heat recovery unit before the entire installation. If you interrupt the installation, make sure the flanges on the top part of the heat recovery unit are closed to prevent construction dust and moisture from penetrating inside. The heat recovery unit is mounted on a fixing bracket, which must be attached to the wall at 4 points (see the figure below). For the attachment use a technology suitable and recommended for the material of the support wall where the unit will be fitted , ,5 Fig. 2 Installation 4.1. Connection of ventilation pipes The heat recovery unit is equipped with 4 EPP 150 mm flanges. For the supply as well as exhaust from/into the outdoor environment EPP pipes must be used to prevent undesired condensation from occurring inside the supply and exhaust pipes. The air supply and exhaust opening must remain free and clear. At the air intake and exhaust to/from the interior it is necessary to install silencers at about 1.5 m according to the manufacturer s specifications and recommendations see Appendix 2. 4

7 4.2. Condensate drain connection In the heat exchanger, the exhausted air is cooled by the supplied air, which causes condensation of moisture in it. The resulting condensed water is drained towards a siphon. The condensate drain connection has an outer thread, which is found at the bottom side of the heat recovery unit. A siphon, which is connected to the sewerage system, must be mounted onto the coupling of the condensate drain connection HT 32 mm drain pipe. Condensate must be allowed to freely flow out of the heat recovery unit by gravity! 32 HT - 32 mm 251 Siphon HL-138 HT - 32 mm Sewerage connection 247,5 Fig. 3 Condensate drain connection 4.3.
