Installation is not recommended for signal quality under -95 dBm. As the cellular network quality may fluctuate strongly across the site, it is recommended to test at different locations. If network quality at the installed location is not sufficient, it may be necessary to relocate the D35 or extend its antenna with adequate CLA-VAL extension cables.
NETWORK QUALITY BETWEEN -80 dBm and -95 dBm If the signal quality at the valve level is between -80 dBm and -95 dBm, check if the D35 can be installed closer to the well opening, while maintaining a maximum distance of 3 m to the pressure sensors. If this is not possible, an antenna extension with optional CLA-VAL antenna extension cables might be necessary.
An optional orientable wall-mounted or valve bracket for D35 is also available. 5.3.3 STRANDARD INSTALLATION The standard installation of the D35 on the wall should be, as close as possible to the well opening, but not further than 3 m from the pressure sensor(s) connection(s) on the valve.

Choose the transfer interval and the time when the transfer will start. This interval will determine the frequency of communications of the D35 and Link2Valves. Please note that a faster interval will have a negative impact on the battery life and generate potential additional data communication costs.
Associate the D35 unit with your Link2Valves user account. First, enter the email address of your Link2Valves account. If you do not have one, please contact CLA-VAL to get one for free. Then click on "REGISTER NOW" and wait for the message "Success! ".
Click on the "UPLOAD FIRMWARE" button and wait a few minutes. Completely power off the D35 to apply the update. To do so, press the product button for 5 seconds to turn off the WiFi.
