Notes!
1. Programming buttons [E], [-], and [+] may need to be pressed and held for several
seconds before displaying the expected response.
2. When performing a calibration the 839E may require up to 60 seconds to learn the high
or low flow rate. The display will indicate “WAIT” during the learn process.
3. After configuring the 839E to the desired settings, press and hold the [E] key until
“SAVE” appears; press the [+] or [-] key until “YES” appears. Press and hold the [E] key
until “SAVE” appears. Depending on the configuration changes the display may
indicate a number or a blinking “INIT.” Wait for the blinking “INIT” to change to another
value. This indicates the 839E is ready for operation.
