Assembly instructions - Corner installation Wall connection is supplied separately. Vertical connec- tions must be affixed first. To do this, simply remove the film on the rear. The cellular rubber can then be affixed flush with the external edge of the heat pump. Additionaly the horizontal elements are also lined on the front.
Installation – Standard air duct If there are no two external walls directly available for Option 2: installation, the air flow can be conveyed outwards via insulated air ducts. Our range includes standard air ducts This method is equivalent to corner installation. This which can be connected directly to the heat pump without method can be used if corner installation is not possible adaptation.
