Manually Operating Wash and Cycling Functions
After all cables and hydraulic hoses are connected, test power to unit by turning external pH
controller power switch to on position. With control switch in manual position, run wash pump
briefly. If water does not flow from jets within 10 seconds, disconnect quick couplers to help pumps
prime. If water doesn’t spray, but pump is running, see Troubleshooting section for instructions on
priming pump. If pumps don’t operate, recheck power cables and connections. If electrical power
to Controller is functioning, test hydraulics by locking hydraulic lever in position, and raising and
lowering sampler shoe using manual Up/Down switch. Test Raise/Lower functions on main lift
cylinder if equipped. Make sure no one is under unit and keep clear of any pinch points.
