Installing wall mount dispensers
WARNING!
§Wall mount dispensers are intended to be mounted
above a sink, eliminating the need for a drain pan.
§Before beginning installation verify that the sink size
and location meet the requirements shown in Fig. 6.
§If requirements are not met, a drain pan must be
used to prevent ice and water from falling on counter
or oor.
§FAILURE TO TAKE THESE PRECAUTIONS
COULD RESULT IN SLIPS AND FALLS ON WET
