ITEM  
DESCRIPTION  
CANOPY  
Removable canopies aid in vapor capture at entry and exit of the conveyor  
warmer. Canopies hang from mounting pins at each end of the hood.  
ELECTRICAL  
EXHAUST  
The hood plugs into a NEMA 5-15R (120V) or 6-15R (208/240V) receptacle  
with a 6' power cord. An illuminated power switch on the front panel is used  
to start/stop the hood fan.  
The hood uses an exhaust fan to provide air movement. The fan exhausts  
through a screened opening in the top of the hood.  
IMPORTANT: DO NOT block exhaust opening.  
FILTERS  
The hood uses two filters. A high efficiency filter is used to capture  
particulate emissions.  
A charcoal filter is used to help control odors.  
Filters are accessed by opening a hinged panel on the front (operator's)  
side of the hood.  
Filter operation is monitored by a vacuum switch. When the filter(s)  
become loaded to the point of being unable to remove particulates, a front  
panel "change filters" indicator will glow.
