Grease Grabber™ H2O System Function

Greenheck GGH2O hoods are designed for three primary functions:

•Capture and contain the effluent produced by the cooking process.

•Remove grease and other contaminants from the airstream with two stages of mechanical filters (Primary Grease X-Tractor filters and secondary Grease Grabber filters).

•Wash the filters and other surfaces within the exhaust plenum to remove contaminants.

NOTE

The wash sequence of the hood is not designed for fire suppression and will not engage in the event of a fire.

NOTE

The functions listed above require the control center to be wired to the exhaust fan(s) and the hood plumbed.

NOTE

For a complete list of functions, please refer to the sequence of operations.

Normal Exhaust Operation and

Contaminant Collection

The system’s exhaust fan is manually controlled by a press-button switch (FAN ON/OFF) on the graphic keypad (included with hood). The exhaust system operates until the FAN ON/OFF button is pressed. The wash cycle can be manually engaged to run on a pre- programmed control sequence by pressing the CLEAN HOOD button or automatically engaged to run at the same time each day through a programmable timer.
