Mitigating Risk when Servicing a Unit
Please review the following before attempting to service a unit

• Inspect outside of enclosure for damage before attempting service. If the unit appears physically damaged in any way, do not redeploy unit. Disconnect the battery if it is safe to do so and contact your Xylem Representative to arrange for safe disposal.
• Do not service the device while the radar is operating.
• When servicing in the field, remove the radar from the manhole and move to a safe and dry location before opening the enclosure.
• Disconnect the battery from the electronic circuitry whenever the enclosure is opened.
• Please read the remainder of this document and adhere to all requirements listed herein.

Battery Requirements
Caution – The battery used in this device may present a risk of fire or chemical burn if mistreated. Do not disassemble, heat above 100C, or incinerate. Replace battery with Vitzrocell SB-D024S+CON only. Use of another battery may present a risk of fire or explosion. Caution – DO NOT attempt to charge the batteries. The batteries are primary cells and should not be charged. Doing so risks potential fire or explosion.

Tools and Consumables

No special tools are required to service the radar.
The installer will be required to replace the tamper detection tag (consumable item) when servicing the unit. The tags are supplied with the support bar installation kit and the support bar service kit. Please refer to the support bar documentation for more information on installation and mounting of the support bar.

Site Installation

Site installation starts with performing a site assessment, followed by installation of the support hardware and then mounting the radar to the support bar before proceeding to install the assembly into the manhole.

Assembly installation
Please refer to the support bar documentation (provided separately) for more information on installation of the support bar in the manhole and attachment to the support brackets.

Configuration

Parameter Adjustment
There are a number of parameters that are used to configure the radar for different site conditions. These are changed by editing parameters. At the time of writing, the parameters that the installer will need to update are:

• (1.0 to 30.0) Total manhole height (in meters).
• (0.0 to 20.0) This is the distance (in meters) from the manhole rim to the lid of the enclosure when installed.

Field Service
Important note: The BLU-X Radar has been designed as a single device. While there are multiple components within the radar, the components are associated with the serial number of the unit and they are not intended to be field serviceable. If a BLU-X Radar device is not performing as expected, please request authorization to return the device for replacement.

Normally maintenance of the unit involves the following few steps:

1. Removal of the radar and support bar assembly from the sewer
2. Inspection and removal of the tamper detection tag
3. Visual inspection of the external surface of the radar enclosure
4. Opening of the enclosure and inspection of the interior
5. Inspection and replacement of desiccant
6. Inspection and replacement of batteries

Step 1 above should be completed according to support bar service documentation. Steps 2-6 are addressed below.

Inspection and removal of the tamper detection tag:

then please record and report the issue and use extreme caution when servicing the unit, as it may have been tampered with; only authorized users are allowed to open the unit.|
| Remove tamper detection tag by snipping it|

Visual inspection of the external surface of the radar enclosure:

significant dents to the base or lid of the enclosure as well as the clasp and hinge. If the unit appears to have been damaged please request a replacement unit.|

Opening of the enclosure and inspection of the interior:

side until the lid releases. Proceed to gently open the lid from the base of the unit|
| Inspect the interior of the unit for evidence of water damage such as pooling water, evidence of water stains, moisture in the interior, or other signs of enclosure failure.|

Inspection and replacement of the desiccant:

connectors. Remove the old desiccant packs and inspect the color indicator on the packs to determine if the desiccant was consumed. Please estimate and record how much the desiccant was consumed.|
| Replace with new packs of the same type.

Inspection and Replacement of Batteries:
Battery removal is described as follows:

replace batteries
| If you have not already done so, please disconnect the battery from the telemetry board by separating the male and female battery connectors. Use caution when separating the connectors.|
| Rotate the hinged telemetry assembly up to access the battery compartment. Take care to avoid contact with wires and electronics. Make sure to use all necessary safety equipment when accessing batteries.|
---|---|---
| Inspect battery packs and battery cables for signs of damage such as corrosion, bloating, or discoloration. If any pack or cable appears to be damaged, do not attempt to service the unit. Please place the unit in a safe location, away from people and potentially flammable items then contact your

Xylem representative. If you cannot reach your representative and/or if you have identified a dangerous safety issue, please contact your local authority.

| If battery packs and cables appear to be in good condition, remove battery packs and safely discard, following all legal requirements.

Note: Dispose of used battery promptly. Keep away from children. Do not disassemble and do not dispose of in fire. Do not attempt to charge battery.

Battery installation is described as follows:

Enclosure should be opened and the hinged telemetry assembly should be up and out of the way to expose the battery compartment
| Obtain three Vitzrocell SB-D024S+CON battery packs. This battery pack has been authorized for use in this application and no substitutions are allowed. Please refer to the battery requirements within the safety section of this document before proceeding. Please reach out to your Xylem Representative before continuing if you have questions.
| Inspect the battery packs to make sure that there are no signs of non- uniformity. Place three (3) battery packs upside-down into the battery compartments as shown, being careful to thread the wiring through the cable management channels. The indication that the battery pack is upside-down is that the cables for the pack will exit the pack at the bottom of the enclosure, not the top.|
---|---|---
| Connect the battery packs in parallel using the integrated battery connectors.

Pack all but one of the cables into the battery cable management chamber. The remaining cable will be connected to the telemetry board when the unit is powered on.

Troubleshooting

Identifying an issue

Hardware Issue
Most issues are easily identified as hardware issues, such as:

• Low voltage Battery packs – as indicated by values on the Blu-X portal
• Moisture in the enclosure – evident without opening the enclosure by looking through the optically transparent lid. If the enclosure is opened, look for pools, droplets on surfaces, and corrosion of metal surfaces and connectors.
• Damage to enclosure – as indicated by cracks in the enclosure, missing pieces of the enclosure
• Damage to internal components – as indicated by loose or broken pieces in the enclosure, etc.
• Cable connectivity issues – as indicated by frayed cables or loose or disconnected cables.

If you identify a hardware issue, please return the device for service.

Configuration Issue
If the BLU-X Radar is reporting an incorrect water level, please double check the configuration settings for the correct manhole height and radar offset values.

Connectivity Issue
When deploying a new BLU-X Radar, if you find that data from the BLU-X Radar are not visible on the BLU-X Portal and there are no signs of physical damage, then it is possible that there is a wireless connectivity issue. The units have been preconfigured for wireless connectivity and communication with the BLU-X platform. Please reach out to your field service manager with the serial number of the radar in question in order to receive further support.

Returning a device for service
If there is an issue which cannot be resolved or if the service technician has identified a hardware issue, please disconnect the batteries if it is safe to do so. Please request authorization to return the unit for replacement. You will receive instructions to safely prepare and return the unit.
