    Preparations Preparations 5.1. Installation Place the unit on an even surface on a pad made of non-flammable material. Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting openings! Never cover these openings! Keep at least 20 cm of open space on the front and rear venting grids. The place of installation should be large enough and provide sufficient air ventilation to ensure the room does not warm up excessively because of the heat the instrument rejects to the environment.
