SINGLE DEFLECTOR BOOM KIT with 3 GPM NOZZLE
• Allows for Multiple Spray Widths, 8 Ft. to 22 Ft.
• Great for Spraying Fence Lines & Ditches
The “No Boom” boom kit is designed to fit many applications. It has been specifically designed to attach easily
to other Master Manufacturing products. The following instructions are intended for the attachment of the “No
Boom” to a Master Manufacturing 2.8 GPM or greater spot sprayer, lawn trailer, 3-point sprayer or ATV kit.
Manifold Replacement for Pump with NPT Fittings
1.) Remove the existing pump from the tank by removing the four screws.
2.) Remove the spray wand hose from the barb fitting on the outlet side of the sprayer pump.
3.) Remove the hose barb fitting from the outlet side of the pump.
4.) Obtain the new manifold (PN34-140118) and connect to QA Fitting with threaded end.
5.) Thread manifold onto pump using thread sealant.
6.) Reattach sprayer pump to tank using the screws removed from step 1.
7.) Apply a thread sealant too the gauge thread and thread gauge into manifold, tighten securely.
Spray Boom Attachment
1.) Attach the two upright spray boom brackets (PN 31-100160) to your lawn trailer, ATV angle
brackets or other application using the four 5/16-18 x 1 bolts (PN 33-100116) and 5/16 nuts (PN 33-
2.) Attach the spray boom (PN 34-140065) to the upright spray boom brackets using two 5/16-18 x 1
bolts (PN 33-100116) and 5/16 nuts (PN 33-100113).
3.) Thread on the boom hose to the manifold valve installed previously and tighten securely.
4.) Boom height can be 24” – 48” above area to be sprayed. Use the location holes in the upright spray
boom brackets as adjustments to obtain the optimum spray height.
1.) Attach the new wiring harness with inline switch to the sprayer pump by pushing the two terminal
Using the No Boom
Your new boom has the capability of using any of the three nozzles independently or simultaneously.
Each nozzle can be individually controlled by its corresponding “valve nozzle”. To allow a nozzle to
spray, turn its corresponding “valve nozzle” to the on position. All three nozzles are then controlled by
one central “boom valve” located on the manifold. The “boom valve” will turn the flow of chemical on
or off to whatever selection of individual nozzles you choose to turn on.
Four things must be considered before spraying with the boom.
1. How much chemical must be mixed in the tank?
2. Rate of spray (gallons per acre to be sprayed.)
3. What pressure (P.S.I) will be used.
4. Speed traveled (M.P.H.) while spraying.
5. Boom height and spray pattern
Refer to the chemical label to determine the chemical mixture.
See the tip chart to determine the pressure, speed and rate of spray to be used for your application.
Check the spray pattern with water only. Usually you can see the coverage better on a solid concrete
surface, such as a driveway.
Operation and calibration
Raise or lower the nozzle so that you will have a good coverage pattern. Generally the proper height will be
approximately 36” from the ground for the No-Boom nozzles and 12-14” for the center deflector nozzle. It is
highly recommended that the center deflector nozzle be run independently of the two No-boom nozzles due to
the different height requirements for spraying and the gallon per acre difference between the two kinds of
Once you know how much you are going to spray then determine (from the tip chart) the spraying pressure
(PSI) and the spraying speed (MPH). The pressure can be set by running the sprayer with the boom nozzles
“ON” and then by adjusting the bypass valve lever until the gauge reads the desired pressure. Notice that the
pressure will go up when the garden hose valve is slowly closed.
When selecting pressure from the tip chart, it is a good idea to try for approximately 30 PSI as this allows for an
excellent nozzle pattern. At 10 PSI the pattern begins to break up and at 40 PSI you may notice some drift.
Conditions of weather and terrain must be considered when setting the sprayer. Do not spray on windy days.
Protective clothing must be worn in some cases. Be sure to read the chemical label carefully. Before spraying
chemicals, fill the tank half full of plain water to allow familiarization with the sprayer and to prevent waste of
expensive chemicals. After all calibrations have been completed, add water and chemicals to the tank. Always
follow chemical manufacturer’s instructions for mixing.
CLEANING & STORAGE
Most spray materials are highly corrosive. The most important aspect of long dependable service from the
sprayer is a thorough cleaning immediately following each use. In addition, the residue of one type of chemical
could cause an undesirable effect when a different chemical is used for a different purpose.
The most effective cleaning method is to pump several rinses of clean water through the tank, pump, hoses,
boom, spray gun, etc. A neutralizing agent such as a solution of Nutra-Sol, a detergent or household ammonia
as recommended by the chemical manufacturer can assist in removal of a persistent chemical. When the system
is thoroughly cleaned, drain the tank, suction line, pump hoses, etc.
The following steps should be followed for the maintenance and storage of your sprayer.
1. Wash and flush out sprayer after completion of each phase of your program. Flush out sprayer when
changing chemicals if there is a possibility of the chemicals being incompatible. Use of a detergent
is advisable if the chemical manufacturer does not make specific cleaning recommendations. Flush
system completely, including nozzles. Never use metal objects to open clogged nozzles.
2. Clean sprayer thoroughly before storing at the end of the spraying season. Permanent
type anti-freeze added to the final rinse will leave a rust inhibiting film in parts of the sprayer.
