    Please read, heed and follow the enclosed information for the installation of the humidifier and the steam, water and electrical networks. For further technical assistance, feel free to call devatec. Failure to adhere to manufacturer’s installation recommendations will invalidate your warranty.
  • Page 11 The rear part of the RTH-LC becomes hot during operation (about 60°C). Make sure that the surface on which the humidifier is installed can sustain hot temperatures. The devatec steam humidifiers are designed to be installed on wall. Make sure that the surface the humidifer is hanged on is strong enough.
  • Page 12 RTH-LC LECTRO Installation - Step 1 NOTA BENE : Use attachment equipment appropriate to the support. Installation procedure : Unpack your humidifier. Mark the 4 mounting holes and drill. Insert pegs. Screw the upper screws (diam 6mm) allowing about 10 mm for hanging the cabinet.
  • Page 13 RTH-LC LECTRO Installation - Step 2 A fresh mains cold water service should be used to supply the unit. The wa- ter pressure should be between 1 & 6 bars & should not exceed 40°C in temperature. In case the water pressure exceeds 6 bar, a water regulator valve must be used.

  • Page 15 RTH-LC LECTRO Installation - Step 3 Evaporation distance or vapor trail « D » A certain length is required so that the steam coming out of the steam distribution pipe be absorbed by the air. All along this length, descrided as the evaporation distance, the steam can still be seen in the airflow as a mist which can condensate in water against any obstacle if placed within.
  • Page 16 A high humidity limit humidistat must be installed in the duct to stop the humidifier in case the level of humidity exceeds the preset value. In case the recommended distances cannot be met, please contact devatec or their authorized agent for an alternative solution.
  • Page 17 Installation - Step 3 Please meet the following dimensions and spaces according to your configuration. For further information, please contact devatec or their authorized agent. H1 = 110mm = Minimum height between the duct floor and the axle of the steam pipe.
