Description, Care and Maintenance
Dry Hopper and Hopper Valve
The Dry Hopper (Fig.10) is used during the initial mixing of the dry product and fluid. The hopper
requires very little daily maintenance. Keeping the inside surface of the hopper clean will help the dry
product flow smoothly into the hopper valve and into the mixing tee. The hopper is not ladders and should
not be climbed on or sat upon as damage can result. The hopper can be removed with relative ease if needed
for transporting size restraints. The securing knob at the rear side of the hopper should be checked regularly
and kept tight to prevent movement.
The hopper valve must be kept free of dried Bentonite, ice or other buildups to reduce the chance of
damage during opening and closing. The valve operates more smoothly if the surfaces are kept damp or wet.
All valves are to be opened and closed by hand. DO NOT FORCE THE VALVE OPEN OR CLOSED,
visually check the valve if a problem occurs!
CAUTION
AVOID ALLOWING FOREIGN MATERIAL
into the Venturi Mixing Tee thru the
Hopper, by keeping the valve closed
when not in use.
CAUTION
DO NOT POSITION
ANY PART OF YOUR BODY
over the hopper, valve,
or mixing tee while cleaning.
WARNING
NEVER USE BODY PARTS,
OR FOREIGN OBJECTS
in an attempt to unplug or clean the
hopper valve or mixing tee.
Serious personal injury or
damage will result.
