Make sure pump heads open and close smoothly.
Inspect tubing and for uneven wear. Replace pump tubing often to ensure high
flow rates can be met.
Tighten hose clamps and check filter. Clean filter frequently to avoid blockages
Flush flow meter with clean water frequently to avoid chemical buildup.
Proper maintenance of the LPH800 Seed Treater is critical for peak performance,
reliability and accuracy of this system. The following is a guideline for the type of

PROXIMITY SWITCH ADJUSTMENT GUIDE
The proximity switches mounted in the extension ring and the seed wheel detect when
seed is present.
The proximity switch located in the extension ring is used to automatically shut off the
inlet conveyor when the surge hopper is full. This proximity switch is not present on
tower systems.
The proximity switches located in the seed wheel automatically shut off the pump when
all seed has left the hopper.
If the proximity switch is not working properly, this can be caused by wear, dust, or
even moisture. The first step is to clean the lens of the proximity switch. If this does
not solve the problem, the next step would be to adjust the sensitivity of the proximity
switch.
The green light indicates the power status. If it is active the device is powered.
The amber light indicates when seed is being detected. If it is active it detects seed,
if inactive it does not detect seed.
Using the small screwdriver provided inside the control panel, you can adjust the
proximity switch by turning the adjusting screw on the back of the proximity switch.
Turn Clockwise to make the proximity switch more sensitive.
Turn Counterclockwise to make the proximity switch less sensitive.
