Abstract: FIELD: food industry. 
     SUBSTANCE: invention relates to aqua vending apparatuses, that is to automatic water dispensers by means of automatically controlled water delivery from common reservoir to consumer container. Technical problem consists in necessity to increase strength and rigidity of bearing panel of front panel at reduction of thickness and weight of metal sheet, from which board is made. Effect of the frame provides the required overall rigidity of the shield along its outline, and the sandwich effect which integrates with the effect of the frame actually eliminates said transverse-flexural deformations by introducing final changes in the pattern of the strained-deformed state of the shield. Facing panel of aqua vending apparatus comprises bearing shield 1 with openings 2, power frame 3 and at least one overlay frame 4. Power frame 3 and mounting frame 4 are stiffness elements of shield 1. In each window 2 there is interface device 5 equipped with mounting elements 6 with holes for attachment to shield 1. Interface device 5 is fixed on shield 1 in appropriate window 2 on inner side of said shield by means of locating elements 6 along perimeter of corresponding window 2 by means of fixing pairs 7 of "threaded element-nut" type. Result is a three-layer "sandwich": overlay frame 4, bearing shield 1 and mounting elements 6 of interface device 5. 
     EFFECT: technical result consists in increase in the front panel strength and rigidity due to the effect of the board material integral effect of the shield material to transverse-bending deformations from the weight of attached to it any interface devices (frame effect, which is a necessary condition for creation of said resistance, and a sandwich effect, which is sufficient condition for creation of said resistance).
