Prerequisite site requirements

• Please ensure your site meets all the Flow Gateway V3 Networking Requirements

• Corporate Wi-Fi network which is accessible from the location of the espresso machine

• A suitable mounting location for the Flow Gateway near the espresso machine (usually under the counter)
  Nb. The supplied flow meter cable is 3 meters long, so depending on the routing of the cable within the espresso machine, this allows for installing the Flow Gateway approximately 1.5-2 meters away from the espresso machine

• AC power outlets near the location of the espresso machine (usually under the counter):
  Nb. The Flow Gateway power supply cable is 1.5 meters long

...

The espresso machine has a flow meter per group head. The flow meter cable has a female and male plug per group head to allow it to connect in parallel with the espresso machine’s connection.

For each flow meter

1. Disconnect the espresso machine’s plug connector from the flow meter terminals.

2. Connect the female connector on the flow gateway cable to the flow meter terminals.

3. Connect the corresponding male connector on the flow gateway cable to the coffee machine’s flow meter connector.

...

Unused connection

If there is a spare connector on the flow meter cable after all groupheads have been connected (ie. when two cables are used for a 3 group head espresso machine), connect the spare male and female plugs together then secure the cable out of the way.

2. Mount the Flow Gateway

1. Locate the Flow Gateway near the espresso machine in a location that will not be affected by excessive heat, and where it will not come into direct contact with water or steam (usually under the counter is the most appropriate location).  Ensure the chosen location is in reach of the flow meter cable and AC power outlets.

2. If the Flow Gateway is located where it may be disturbed, or if it is installed on the wall or underside of a counter, secure the Flow Gateway using the supplied dinrail and black mounting bracket that screws to the back of the Flow unit. Fix the dinrail to the desired mounting location using high strength double-sided foam tape (eg. 3M VHB Double Sided Foam Adhesive). Then clip the unit(now fitted with the black mounting clip) to the dinrail.

3. Route the flow meter cable(s) to the Flow Gateway and secure the cable

1. Route the cable(s) through the service hole in the bottom of the espresso machine then to where the Flow Gateway will be located.

2. Secure the cable(s) inside the espresso machine so that cannot touch any hot components like water piping or the boiler, and so that it cannot be dislodged if it is pulled from outside of the espresso machine.

3. Plug the flow meter cable(s) into the Flow Gateway (take note of which cable is connected to groupheads 1/2 and which cable is connected to groupheads 3/4. Plug into the corresponding ports on the Flow Gateway).

4. Connect the Flow Gateway power

1. Install the Flow Gateway power supply, secure the cable, press the power button. NB: not to be confused with the reset button.

2. The screen will illuminate when the power has been turned on.

5. Setup the Internet connection
