The ePump can be operated by one of three
(3) controllers: the ePump controller (JEP-R), the
AquaLink® RS controller (Rev O or later), or the
AquaLink® PDA (Rev 4.0 or later).
The ePump communicates with the controllers via a
four-wire RS-485 interface.

hazard, resulting in severe personal injury or death.
2. Remove the cover of the ePump junction box and
feed the RS-485 cable into the fitting.
3. Unplug the RS-485 connector from the ePump.
