1. Introduction to CleanFLEX CleanFLEX(CAM) is a smart fill-level sensor that can be easily installed on any type of container. It uses robust ToF VCSEL (Time of Flight, Vertical Cavity Surface Emitting Laser) technology, allowing it to monitor any type of non-transparent solid substance. In addition, CleanFlex can take pictures of the inside of the trash bin using the built-in camera, and the photographed photos are transmitted to Clean City Networks wirelessly along with the collected bin fill-level and trash bin status information. CleanFLEX communicates with CCN through 3G. Obtaining real-time fill-level data of bins empowers the user to make data-driven decisions. 1.1 CleanFLEX contents When you receive CleanFLEX, ensure you have all items mentioned in this section. 1.1.1 Included in CleanFLEX box Each CleanFLEX box is shipped with the following:

2. Installing CleanFLEX CleanFLEX can be installed inside of waste containers or under its lid. If the installation is for a waste container with a lid, CleanFLEX should be mounted under the lid. If the installation is for a waste container without a lid, CleanFLEX should be mounted on the inside of the waste container. CleanFLEX must be installed, connected, commissioned, operated, and maintained by qualified personnel only. 2.1 Installation prerequisites The accuracy of CleanFLEX data is affected by the location and environment of installation. It is recommended that CleanFLEX be installed with the direction of the sensors light beam being perpendicular to the bottom base of the waste container (or bin). If necessary, please adjust the angle of the ToF sensor. If the direction of the light beam is not perpendicular to the base of the waste bin, the distance traveled by the reflected light may not be the same with the bin profile and may result in inaccurate measurements. In order to receive accurate fill-level data, the user must enter the sensor and bin height into CleanCityNetworks. Refer to Section 4 (Bin Profile) for more information. Any protruding objects (i.e., vinyl bin liner) between the light beam and the bottom base of the waste bin may affect fill-levels. CleanFLEX's cameras have a wide angle of view, but they may need to be adjusted as they may be obscured by the internal structure of the trash bin. CleanFLEX(CAM) User Manual

2.2 Installing CleanFLEX Fill-level accuracy depends on how well it is mounted and configured. Depending on the container type, it may be necessary to seek advice on appropriate installation location and method of installation. Ensure you have the following items before beginning the installation:

Stencil pen, marker M6 drill bit Power drill Torx driver M6 torx bolts (2 EA) CleanFLEX Take the following steps to install CleanFLEX under the lid or inside the bin. 1. To determine the mounting location of CleanFLEX, find a spot with a clear line of sight to the center of the bins bottom base. Use a stencil pen to mark the spots where you will drill holes. 2. Using a power drill with an M6 drill bit and drill holes on the marked spots. 3. Position CleanFLEX on the installation surface and tighten with screws from the other side. 4. Make sure the sensor is pointed at the center of the bottom base of the bin. Change the angle of CleanFLEXs adjustable sensor head if necessary. 5. Make sure CleanFLEX is securely installed. If the installation surface is too thick, use long M6 torx bolts to secure CleanFLEX. CleanFLEX(CAM) User Manual

For CleanFLEX installed underground, it is highly recommended to perform Set Manual Location as CleanFLEX installed underground does not obtain accurate GPS location coordinates. Take the following steps to turn CleanFLEX on. 1. Place the magnet on the indent located on the side of CleanFLEX and hold it there for 5 to 10 seconds and then remove it. 2. The LED light will blink red and then eventually turn green. Please note that removing the magnet too soon (<5 seconds) or too late (>10 seconds) will fail to turn the unit on. After the unit is on, it will try to reach the server. The green LED will blink 5 times rapidly to show that it successfully communicated with the server. CleanFLEX(CAM) User Manual

3.3 Turning CleanFLEX OFF Take the following steps to turn CleanFLEX off. 1. Place the magnet on the indent located on the side of CleanFLEX and hold it there for 5 to 10 seconds and then remove it. 2. The LED light will blink green and then eventually turn red. Please note that removing the magnet too soon (<5 seconds) or too late (>10 seconds) will fail to turn the unit off. Before the unit turns off, it will try to reach the server. The red LED will blink 5 times rapidly to show that it successfully communicated with the server. Avoid performing any procedures within ten minutes after turning CleanFLEX off. If the user fails to follow the appropriate steps to turn CleanFLEX off, CleanFLEX will return to its previous ON status. CleanFLEX(CAM) User Manual

4. Bin profile For accurate fill-level measurements, the user must create a bin profile for each unique bin CleanFLEX is mounted on. The dimensions mentioned in the diagram below are essential in creating the bin profile on CCN. If you fail to create an accurate bin profile using these dimensions, then CleanFLEX is set to a default bin profile which may lead to inaccurate measurement data. Refer to the CleanCityNetworks Users Manual for creating bin profiles for CleanFLEX. Bin Profile 1. Profile name 2. Sensor height 3. Bin volume 4. Bin height 5. Bin base

(width &

length) If the direction of the light beam emitted from the sensor is not perpendicular to the center of the bins bottom base but emits at an angle (i.e., mounted off center or on the wall of a container), measure the distance from the sensor to the center of the bins base (rather than the sensor height) for more accurate results. The Pythagorean Theorem (a2 + b2 = c2) can be utilized to find this distance (c2 or the hypotenuse) by measuring the sensor height (a2) and the floor distance from the sensor to the center of the bins base (b2).

4.1 Placing liner bag inside the waste bin If using bin liners, please ensure the following steps are followed. Failure to follow the instructions may result in inaccurate fill-level readings. 1. Fill the bin liner with air before inserting it into the bin. 2. Fold the top of the bag over the top edge of the bin while pushing the bin liner against the inside of the bin to keep the bag away from the center of the bin. 3. Fold the excess length of the bag over the outside of the bin. The liner bag must be pushed completely to the sides of the bin. If the liner bag is protruding toward the center of the bin, it will lead to inaccurate measurement data. After the liner bag is placed in the bin, ensure the inside of the bin looks as illustrated below. CleanFLEX(CAM) User Manual

5. Troubleshooting check the following. If you experience network problems or operation issues after installing CleanFLEX, 5.1 Fill-level measurement issues Visually inspect the installed CleanFLEX and:

Check whether the sensor is surrounded by any foreign substances Check the status of liner bag Check for damages on the sensor If foreign substances are found around the sensor, remove them. If the liner bag is not placed properly, refer to 4.1 Placing liner bag inside the waste bin and place the bag correctly. Also check whether the sensor is physically damaged. In case of damage, contact Ecube Labs or point of purchase. 5.2 Taking pictures issues Visually inspect the installed CleanFLEX and:

Check whether the camera is surrounded by any foreign substances Check whether the sensor is damaged If there is any foreign matter or condensation, please remove it. Also check whether the sensor is physically damaged. In case of damage, contact Ecube Labs or point of purchase. 5.3 Telecommunication and Battery issues Occasionally the network provider may experience temporary outages and CCN will highlight a particular CleanFLEX unit with a red icon. Occasionally a units battery status may temporarily drop to Low or Critical (even for a new unit) and you may experience network quality or connectivity issues. Often times, both of these issues resolve themselves on its own. If no improvement is found after several days or you suspect you have depleted your units battery, please contact Ecube Labs or point of purchase. CleanFLEX(CAM) User Manual
