INSTALLATION

  • The fan’s motor is equipped with an internal temperature limit fuse protecting the engine from its overheating
  • The unit set does not include a feeding cable or a master switch
  • The electrical installation and connection of the automatic control should be carried out in accordance with the electrical diagram by      an appropriately qualified person
  • The installation of the unit on the water side should be done in a such a way that enables future maintenance
  • Both stub pipes should be connected to manual closing valves in order to cut off the device
