Handler I, II & III Operator’s Manual - October 2008
Troubleshooting
The Focus Industries Inc. Handler is a simple eduction system
that employs a venturi suction system to place product into
your sprayer tank. It is a convenient and reliable system which
requires minimal maintenance.
The following troubleshooting section lists many of the prob-
lems you may encounter. It defines the possible causes and
presents solutions to the problems. If you have a different prob-
lem, even after having read through this troubleshooting section,
please call you local Handler dealer or the factory. Before you
call, please have this Operator’s manual as well as the model
type and operating system you have purchased available for
reference.
Problem
Cause
Solution
Venturi won’t suck
Improper installation of venturi
Check to make sure the venturi has been installed in the
proper direction and ensure that the nozzle of the venturi is
in place.
Improper line size
Check to make sure the discharge line is large enough to ac-
commodate the flow of the mixture. Discharge line should
be no smaller than the size of the fittings that make up the
venturi package (2” or 3” depending on the model).
Obstructions in the lines
Check to see if there are obstructions in the line after the
venturi. This can be done by running a hose directly from
the venturi to the top of the sprayer tank, bypassing all of
the sprayer plumbing.
Venturi will suck, but not when
the lines are hooked to the spray-
er, or your sprayer fills up before
all the product can be sucked from
the Handler.
Improper fittings
If the venturi is sucking properly, check all fittings to make
sure they are not smaller than the hose size being used.
Note that tees and elbows will add back pressure and reduce
the performance of the venturi, so avoid or reduce the use of
these where possible.
Filter
One of the most common causes of back pressure and
reduced venturi performance is the presence of filters in the
fill line at the sprayer. If you insist on having a filter at the
inlet to your sprayer be aware that it will effect the perfor-
mance of your venturi.
Your sprayer inlet is 1 1/2” or
your tank is smaller than 500
gallons
Your Handler must be adapted to 1 1/2” fittings. The easi-
est way to do this is to change the camlock sizes of your
2” Handler to 1 1/2” using reducers and 1 1/2” camlocks.
Simply reducing your hose from 2” to 1 1/2” at the sprayer
will not work.
Jug won’t puncture properly
Dull blade
Resharpen the knife assembly by removing the assembly
and hand sharpening with a file or grinder.
Jug won’t puncture properly, jug
won’t empty
Extra thick jug
Some of the jugs on the market are extra thick. We rec-
ommend puncturing the bottom of any jug off of the thick
reinforced seam. This is the weakest point on the container
and it cuts up the side of the container allowing for full
drainage. See image below for proper puncture location.
