The drain plug allows a condensate drain hose (mm diameter) to be push connected and mechanically secured (See Fig. 1 & 2). 2.3.1 The drain must have a continuous minimum fall of 6mm per 1m run and can either be chased into the wall or run downwards from the unit into the nearest waste water network. 2.3.2 In some instances, a condensate connecting point will already be provided as part of the building design. The position of this point, relative to where the HRV1 unit is to be installed should be checked for any connection misalignment and any necessary adjustment made before proceeding any further.
