SPRAY CONTROL VALVE WIRING
MAINTENANCE
FILTER CLEANING
The fluid in the sprayer is continually being filtered through
a screen filter. The sprayer must have clean water to prevent
clogging of the screens and check valves when in use. These
screens must be cleaned daily or more often as required. To
clean, follow this procedure:
- The motorized ball valves equipped on the sprayer
require 12V+ constant power and ground to make
actuate. When 12V+ is sent from the controller thru
the signal wire per each section the valve will open as
long 12V+ is present to the section wire. Once power
is removed by turning off the individual or master
switch, the valves will close.
- Each motorized ball red wire connects to the 12V+
terminal. Each motorized ball valve black wire will
connect to ground terminal, and each motorized ball
valve white wire will connect to the corresponding
section terminal.
1. At the start of each day before the water and
chemicals are added, the screens should be
checked and cleaned.
2. If there is water or solution in the sprayer, close
Valve 1 (figure 22, page 8) and valve 4 (figure 21)
to isolate the screens.
3. Loosen the filter bodies by hand. Do not use a
wrench as this could damage the filter body.
4. Remove the screens and inspect them for foreign
material.
5. Clean them using clean water.
6. Inspect for holes or tears. If there is damage,
replace.
7. Install the screens and body to the filter heads and
tighten by hand. Do not use a wrench as this might
damage the body. Do not overtighten and crack
the head.
8. Open valves 1 & 4 to allow the solution to circulate.
9. Drain all screens before storage to avoid freezing.
