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.
The wash sequence of the hood is not designed for
fire suppression and will not engage in the event of
a fire.
The functions listed above require the control center
to be wired to the exhaust fan(s) and the hood
plumbed.
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.
