Mounting 25 The cooling unit can be mounted as standard 251 270 120 either to the outer surface or inside the enclosure, 95 as required. Cutouts and fixing holes should be made on the mounting surface in accordance with fig. 3.1. Cut the enclosed seal to the required length and attach to the unit in accordance with fig. 3.2. Screw the set screws, item , into the blind nuts � and fix them by means of a bracket, item , � washers, item �, and nuts, item �, in accord- ance with fig. 3.2. Attach the condensate drain (see 6.3). Prior to mounting, ensure that: v the site for the enclosure, and hence the arrangement of the cooling unit, is selected so as to ensure good ventilation; v the location is free from excessive dirt and moisture; v the round cut-out for air extraction is located in the upper area of the enclosure; v the mains connection ratings, as stated on the rating plate, are available; v the ambient temperature is no higher than 6..6 specified on the rating plate; (horizontal wall-mounting) External Internal v the packaging shows no signs of damage; v the enclosure is sealed on all sides.
