•Correct supply voltage

•Proper connections to fire

suppression system

2.Check to make sure the disconnect switch on the electrical control cabinet is switched to the “ON” position.

3.Prime the recirculation pump. Remove the plug on top of pump and use a funnel to add water to the pump. This only needs to be done one time prior to initial start-up.

4.Add detergent to the detergent tank in the cabinet.

5.Clean the control cabinet of any debris that may have entered the cabinet during installation.

6.Close the cabinet doors and press the Fan On/Off button.

7.Check the exhaust and supply air volumes.

8.Press the Fan On/Off button to turn the fans off.

9.Press the Clean Hood button.

When the hood is filling, check to ensure water is not leaking through the edges of the access doors. If so, the inlet water pressure is too high. Slowly close ball valve located before the inlet solenoid on the hood top until no water leaks pasT the access doors.

After the hood fills with water and starts washing the primary filters, open water valve slowly until water mist is felt above equipment. Then slowly close valve until water mist is no longer felt above equipment. Once the valve is set it will not need to be moved again.

Verify the Grease Grabber H2O sequence of operation (see the diagram of wash sequence on page 20) during the detergent pump cycle.

Daily Operation of the GGH2O Hood

Pressing the FAN ON/OFF button will start/stop the exhaust and supply fans if interlocked.

Pressing the HOOD LIGHTS button will turn on/off the hood lights.

Initiating the wash cycle:

The Grease Grabber H2O has an automatic timer that can be set to control the wash schedule and automatically start the cycle. See Timer Programming on page 18.

To initiate the wash cycle manually, press the CLEAN HOOD button on the keypad. If you press this button while the fans are running, the system will stop the fans and then start the wash cycle. When the wash is completed, the system will automatically reset itself.

If the fans are controlled by a building management system (BMS), the steps above still apply unless a special program is requested to bypass having to initiate the wash cycle by pushing the FAN ON/OFF and CLEAN HOOD buttons.

Refer to the Grease Grabber™ H2O Hood checklist on page 27 for detailed instructions on start-up operations.
