Top Air Discharge Kit
The top air discharge kit can be used on select ice machine 
models. This kit directs warm exhaust air upward rather 
than out the side panels. Top air discharge kits require the 
same clearance requirements as the comparable self-
contained air-cooled model. Contact your local distributor 
for details.
