    Installation : Mounting Mounting Multi purpose The enclosed bracket can and should be used, both for wall and for ceiling installation. The mounting bracket bracket will automatically tilt the unit 1° towards the condensate drain, when mounted un- derneath the ceiling (fig. 16) and when maounted on the wall (fig. 17). Fig.
  • Page 17 Installation : Mounting Under ceiling Please follow this below procedure for ceiling installation installation Step Action Illustration The HCC 260/360 should always tilt minimum 1° towards the drain side(T4). This is achieved when us- ing the enclosed bracket, 320 mm placed at T4 end of unit.
  • Page 18 Installation : Mounting Connect duct Connect ducts (specification according local regulations), with spigot connection only. system WARNING: NEVER screw any spigot for ducts, directly onto the sheet metal of the unit. Fig. 18 Insulate the ducts according local requirements, taking the installation surrounding tempera- ture into consideration.
  • Page 19 Installation : Mounting Drainage It is mandatory in any HCC 260/360 installation to connect a water drain hose to the unit, consideration because the humidity from the extract air condensates to water drops when cooled in the heat exchanger. This water is harmful to its surrounding if not managed correctly. The installation thus needs a condensate water drain hose connected with a decline of minimum 10 Promille (1 cm/meter) away from the unit and the hose must NEVER exceed the level of the lower sheet metal plate.
