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.
