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 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.

EXHAUST 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.

NAMEPLATE Provides Manufacturer, Model and Serial Number information.

Also, provides electrical ratings.
