Pump Discharge Controls
Three valves control the discharge of liquid to the rear boom, the spray gun, and the
re-circulating line. The valves that control the discharge to the boom and spray gun are located on the
right side of the pump housing.
(On pumps prior to 6/96, valves are located on the left side of pump.)
The valve controlling the re-circulating line is located on the pressure control unit. Normally, the
valves controlling the boom and spray gun discharge lines should be fully opened when either of these
components are to be used. The valve controlling the re-circulating line can be left in the closed posi-
tion if only water is being used. If a disinfectant or other chemical and water mixture is being used,
the re-circulating feature can provide agitation of the mixture. Fully opening the re-circulating valve
will greatly decrease the pump pressure; therefore, only partially open the valve.
Boom Nozzle Controls
On the poultry house washer/
sprayer, each wall nozzle, as well as the
floor/ceiling nozzle are independently
controlled with valves. These valves are
located on the distribution manifold at
the rear of the washer/sprayer.
Washing Sidewalls or Curtains
Place the four valves that control the wall
nozzles in the open position. Make sure the valve at
the pump that controls the boom discharge line is
open. Make sure the break-away feature of the boon
is operational. Engage the tractor PTO and bring the
engine up to PTO working speed.
It is recommended that two passes be made
for each wall. The first pass wets the material and
aids in loosening it for removal by the second pass.
For maximum cleaning, the sprayer should be
operated at a ground speed of 1 to 3 mph. However,
this may vary depending on the degree of build-up
on the wall or curtains.
