Troubleshooting
When servicing of a Hypro Cleanload, be sure that all pumps are disconnected from energy sources
Symptom Probable Cause(s) Corrective Action
Slow Eduction Rate
Flow restrictions on outlet side
of eductor.
Replace 90-degree fittings with sweeping bends using
reinforced hose, especially near the eductor outlet.
Use 2” (51mm) or larger hose and fittings all the way
back to and into the tank. If sharp bends cannot be
avoided, use oversized hose and fittings to minimize
flow restriction.
Not enough flow Check Pump
The eductor nozzle is plugged.
Looking down into the hopper outlet with the hopper
valve open, observe the liquid jet should be centered
and straight. If it is off-center or if it is dispersed, flush
the system with clean water and remove the fittings
from both sides of the eductor. Using a soft tool (wood
or plastic) and taking care to not deform the orifice,
clear the blockage by pushing it back out toward the
inlet side of the fitting. A blocked eductor nozzle
indicates that a filtration problem elsewhere in the
system must be corrected.
Plugged Container
Rinse Nozzle
Debris in the Container Rinse system.
Replace nozzle and make sure there is proper filtration
in the pump system before the Cleanload inlet.
Leaks
Loose fittings. Cracked fittings.
Over- torqued fittings.
Tighten fittings. Replace fittings. Ensure proper torque
(30 in-Lb).
