PREPARATION FOR USE

• Mount the sprayer securely on the pannier

• Connect the power lead to the battery (Brown to + Blue to -)

• Choose the applicator: –
  – To fit the hand lance connect it to the back delivery hose from the pump, the nozzle fitted will give a hollow cone spray
  – The spray boom is fitted to the bracket at the rear of the sprayer and is held in position by a thumb screw (the nozzle should be approx. 400mm-500mm (16”-18”) above ground)

• Make sure the black delivery hose is secured firmly in place on the boom fitting

• Commence spraying by operating the on/off toggle switch control. The pump may take time to dispense any trapped air in the system, when an even flow is achieved commence spraying.

TROUBLESHOOTING

• If the pump fails to operate:
  – Check the electrical connection

• If the pump fails to deliver: –
  – Check suction hose is in the correct position.
  –  Check the filter head of the pump is clean.

CALIBRATION
Calibrate as directed by the chemical manufacturers’ instructions

A SIMPLE GUIDE TO CHEMICAL / FEED APPLICATION
If the area to be sprayed is 3000 sq. meters. and according to the instructions of the liquid bottle you select says sufficient for 1000 sq. meters. Put 3 bottles in the tank and go over the area (north/south, east/west) until the tank is empty.
Please note that having tested your sprayer with water as advised you may not require a full tank of the mixture. Therefore, adjust requirements accordingly.

UNDERSTANDING CALIBRATION
The law requires some 30,00 contractors and employed persons involved in pesticide applications to obtain a Certificate of Competence.
This person will receive a good grounding in the safe and efficient use of pesticides. The exemption rules are such that there will be a large pool of people applying pesticides who, at best, will not have undertaken recent training. A few far-sighted employers have incurred not inconsiderable costs by including all their employers on the training courses and will more than recoup on this investment over the years in increased efficiency.

Why Calibrate?

It is now a legal requirement for all users to adhere to the label recommendations with regard to dosage rates, method of application, etc.
Besides being illegal to exceed the maximum recommended dose, getting the application rate wrong can have distinctly adverse effects on the cash flow and budgets.
Consistent overdosing of sites is not only environmentally undesirable; it also increases the risk of damage to non-target species and run- of damage in more sensitive areas. It can, even with a modest spraying program, cost hundreds of pounds each year in wasted chemicals and unnecessary losses.
Underdosing, on the other hand, can be equally costly. If weeds, for example, are not controlled at the first application, a second later application may be necessary. This may involve higher rates, a more expensive chemical or even hand weeding. Add to this the disruption to work schedules and it becomes evident that careful monitoring and control of all application programs is essential.
Correct application and efficient monitoring is only possible if all personnel involved have a thorough understanding of calibration techniques.

TERMINOLOGY

Treated Area
All chemical data, whether in advisory leaflets or label recommendations, is stated in liters or kilograms of product per treated area. The actual area to be treated thus has to be calculated for budgeting, purchasing, job planning, and calibration purposes.

Overall Application
The treated area is equal to the gross area

Band Application
The treated area is less than the gross area and is calculated thus: Bandwidth x Band lengths x No of bands

Spot Application
The treated area is significantly less than the gross area and is calculated thus:
Area of spot = 0.7855 x (diameter) ² (meters) (derived from πd ²) 4
The treated area (ha) = Area of spot x No of spots per ha ÷ 10,000
Quite obviously, the smaller the area that can be treated to achieve the desired result; the less costly the operation. With the area calculated, the variables involved can be determined in order to calibrate equipment to complete the spraying operation in a safe and efficient manner.

Forward Speed
With overall and band applications, control of forwarding speed is critical in determining how much chemical is applied. This will vary with the type of terrain and must be realistically calculated. In flat terrain where unimpeded progress is possible, forward speed will be greater than in undulating, heavily vegetated conditions. In the latter, the trial may be necessary to determine a constant work rate, which can be, maintained both up and downhill.

Swathe width
The width covered at each pass is known as the swathe width and will vary with, for example, choice of the nozzle, operating pressure, and height of application. Having selected the appropriate nozzle and operating pressure the height selected must in the case of hand-held equipment be comfortable for the operator.
Equipment is comfortable for the operator. With non-pressurized equipment, such as CDA and gravity systems, there are obviously no operating pressures to worry about.

Nozzle Output
Nozzle output is critical in all spraying operations and it is important to select a nozzle type appropriate to the viscosity of the concentrate being applied/swathe width required.

Flow Rate
The flow rate will vary with nozzle type, viscosity, pressure, and ambient temperature at the time of application.
After selecting the most appropriate nozzle for the operation adjustment to pressurize equipment will be necessary to achieve the desired flow rate. The flow rate in powered machinery can be controlled by engine speed and/or internal pressure adjustment.

Application Rate
Spray coverage of the target being sprayed should be sufficient to give an even application of the correct dose of pesticide on the area to be treated. The manufacturer’s recommendations must be followed and where there is a choice of options, i.e., high, medium, low, very low volumes, select the most appropriate volume to achieve the desired result.

Tank Dilution
From the application rate, it is possible to calculate the amount of pesticide required per full tank. Pesticide per fill (litres) = Tank volume (litres) x Pesticide volume (litres/ha ÷ Diluent’s volume (litres/ha) .

CALIBRATION TECHNIQUE

Having determined the above, the next step is to calibrate the actual equipment chosen to apply the required amount of concentrate on the target area.
Each type of application obviously has its own calibration method which must be studied and closely followed, but in general, the following notes for spraying equipment will hold good.
It is most important to understand that each applicator will vary slightly from others of the same type and manufacture. Thus, each piece of equipment must be individually calibrated.
The selected nozzles should be filled with water and the correct operating pressure selected.
The output of each nozzle should then be measured by spraying into a measuring jug for a set period of time, e.g., one minute, to give the nozzle output in liters/minutes.
As output will vary from nozzle to nozzle, in boom equipment the output from each nozzle should be checked. In larger boom equipment, at least four nozzles should be checked- one from each section and the output calculated accordingly. If nozzle outputs on boom equipment vary by more than 5%, the faulty nozzles should be replaced.
If output varies by a small amount from the calculated output, with some types of equipment, altering the operating pressure can rectify this. Where the output varies by a large amount, the calibration calculations should be re- checked and the nozzle type changed if necessary.
With all equipment, the application pattern is checked and swathe width is measured by treating an area of dry soil, concrete, etc.
Once the actual output is known, the forward speed can be calculated, in the case of liquid sprayers, thus: Forward speed (meters/hour) Measured nozzle output liters/minute) x 600,000 x (no of nozzles) Volume rate (liters/ha) x Swathe width (meters) The equipment can then be filled with the recommended mixture of pesticides and dilatants. Never add pesticide concentrate direct to an empty tank, always half-fill the tank with dilatants prior to adding the concentrate, and mix thoroughly.
A suitable test area. e.g., A 100m strip can be sprayed at this speed. At the end of this, the actual application rate should be determined by topping up the tank using a measuring jug. The forward speed can then be adjusted to ensure that the concentrate is applied at the correct rate.
The serviceability of the equipment can be tested at the same time. Leaks are environmentally unacceptable and waste expensive. Blockages lead to patchy results and both make efficient monitoring impossible.

The full calibration process is only necessary when equipment has not been used for a while, after servicing, or after changes in nozzles and pressure are made.
It is, however, good practice to check the actual application rate at the commencement of each day’s work and after lunch. Adjustments can be made as appropriate.
Each employee will require access to a stopwatch and tape measure in order that they can monitor their own output. If resistance is met then this is a good indication that the employee has not understood the reasons behind the calibration process and further training is needed.
The process can be tedious but as operators become more familiar with the techniques, the loss in application time is reduced and more than offset by the improved results obtained.
Much can, of course, be done by management to simplify the task by the production of job sheets clearly setting out the details of each task and providing space for records to e  ept. These when returned, can be filed and the statutory requirement for adequate records to be kept met.

MANAGEMENT TASKS

1. Analyze the objectives of the operation
2. Select the most effective chemical to achieve these objectives
3. Check the manufacturers’ recommendations to ensure that it is suitable for the task and select an appropriate application rate
4. Select the most efficient equipment to apply the chemical
5. Calculate the dilution rate per tank: Pesticide per fill  Tank volume (1) x Pesticide rate (1/ha) ÷ Dilatant’s rate (1/ha)
6. Select an appropriate tank pressure for pressurized equipment
7. Select the correct nozzle to give the required swathe width
8. Calculate the gross area
9. Calculate the ACTUAL area to be treated. Overall application: Treated area = gross area Band application (ha): Treated area = Bandwidth (m) x Band length x no of bands Width between row (m) Spot treatment (ha): Treated area = [0.7855 diam² (m)] x no spots/ha ÷ 10,000
10. Calculate an optimum forward speed based on the equipment to be used, the terrain type, and the ease of movement
11. Issue comprehensive yet simple instructions to staff
12. Ensure that a record of the operation and its effectiveness is kept and any problems investigated fully

SUPERVISORS TASKS

1.  Read notes provided and check details
2. Check weather including wind speed and re-schedule operation if unsuitable conditions prevail
3. Ensure all operatives are issued with the correct safety wear, that this is serviceable and worn
4. Fill the sprayer with water and set it to the correct pressure
5. Measure nozzle flow rates using a measuring jug Nozzle output (1/min) = quantity of spray in a jug (ml) x 60,000 ÷ Time (sec)
6. Adjust pressure to give calculated output (if possible). If significant variation from the calculated output, check calibration calculations and, if necessary, change nozzles
7. Spray an area of concrete or dry soil to determine the actual swathe width and for an even droplet pattern. With a boom, equipment ensures that the spray pattern from each nozzle overlaps correctly
8. Check for leaks and blockages. Blockages should only be cleared by using compressed air and never with wire!
9. Using the actual nozzle output and the actual swathe width determine the actual forward speed required to apply the correct quantity of chemical Forward speed = Nozzle output x 600,000 x No of nozzles ÷ Volume rate x swathe width
10. Compare this with the optimum speed and recalculate the operation if necessary
11. Fill the tank with the correct quantity of concentrate/dilatants
12. Mark out an appropriate test area, spray, and calculate the actual application rate. Adjust the forward speed as appropriate
13. Issue clear and simple instructions based on the actual output of the equipment
14. Monitor the operation and ensure that regular checks on output are made
15. Ensure that tank washings and surplus chemicals are disposed of safely in accordance with the law
16. Ensure that adequate records are maintained on the basis of the actual operating parameters.

INSTALLATION & SERVICE INFORMATION

DESCRIPTION FLORET
Industrial Duplex II Pumps are designed for a wide range of applications and are constructed from a selection of materials suitable for handling a broad range of chemicals. The Duplex II series of diaphragm pumps are self-priming and can be run dry without harm. They are intended for intermittent duty cycles but can be run continuously for short periods of time. The higher the duty cycle the shorter the expected life of the pump. Typical pump uses are liquid transfer, spraying. cooling, circulation, fitration and dispensing.

OPERATION
To start and prime the pump, the discharge line must be open allowing trapped air to escape thus avoiding the potential of airlock. The pressure switch will shut off the pump automatically when the discharge valve is dosed and the pressure has risen to the switch OFF set point. The pressure switch will restart the pump when a valve is opened and the discharge line pressure drops to the ON set point of the pressure switch.

DEMAND OPERATION (INTERMITTENT DUTY)
Demand Operation is considered an “intermittent duty” application. The maximum intermittent duty cycle is that which will cause the motor to reach its maximum thermal limits. Once the maximum thermal limit is reached, the motor must be allowed to settle to a lower temperature ideally being ambient before resuming operation. Running the pump at or near the maximum thermal limit for an extended period of time will shorten the life of the pump and may result in immediate pump failure.

BYPASS OPERATION (IF EQUIPPED)
Models equipped with an external bypass system are designed to pump at high pressures while at low or high flow rates. Models equipped with a bypass only will continue to run until the power is manually turned off. The Duplex II pumps are not recommended for continuous duty service due to limited motor brush life. Operation at lower pressures and temperatures, however, will extend overall pump service life.

MOUNTING

The FLOJET Duplex II Series pumps are self-priming. Vertical prime may vary depending on the fluid viscosity, and suction tube size. foot valve and pump configuration. The pump should be mounted in a dry and adequately ventilated area. If mounted within an enclosure, provisions to cool the motor may be necessary.

PREVENTATIVE MAINTENANCE TIPS
If pumping a liquid other than water the pump should be flushed with water (if applicable) after each use. Sealers and Teflon tape acting as a lubricant can cause cracked housings or stripped threads due to over-tightening. Care should be used when applying sealers: the tape may enter the pump inhibiting valve action. causing no prime or no shut-off conditions. Failures due to foreign debris are not covered under warranty. Before freezing conditions occur. the pump must be liquid-free or winterized with proper anti-freezing chemicals. If mounting the pump in an outdoor environment the pump should be shielded from water. dust, sunlight and wash down spray. Do not assume chemical compatibility. If the fluid is improperly matched to the pumps Elastomers. the pump may fail to prime. have low pressures or the pressure switch may not shut off.

PLUMBING

Use a flexible hose of the correct pressure rating that is compatible c with the fluid to be pumped. Tubing should be a minimum of 3/8″ (9.5 mm) ID and at least 20 inches (508 mm) in length to avoid excess stress on the pump ports. Do not crimp or kink the tubing. The pump head maybe rotated in 90′ increments to simplify plumbing. FLOJET does not recommend the use of metal fittings. standard plastic male and female threaded fittings can be acquired at commercial plumbing supply stores. FLOJET also distributes plastic bath fittings through our distributors (form no. F100-001). The use of check valves in the plumbing system could interfere with the priming ability of the pump. If a check valve is installed in the plumbing it must have a cracking pressure of no more than 2 PSI (.14 bar). Use of a minimum 40-mesh strainer or filter in the pump inlet line will prevent foreign debris from entering the system. Failures due to foreign debris entering the pump will not be covered under the limited warranty. Note: Inlet pressure must not exceed 30-PSI (2.1 bar) maximum.

WARNING
Risk of an electrical shock!
When wiring electrically driven pumps. follow all electrical and safety codes. as well as the most recent National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
Make certain the power source conforms to the pump voltage. Be sure all power is disconnected before installation.
The pump should be wired into an individual (dedicated) circuit, controlled with a ULJC-UL certified double pole switch rated at or above the fuse ampere indicated on the pump motor label.
On 115-volt AC pumps. the black wire lead is live or common. the white lead wire is neutral and the green/yellow is ground.
On 230-volt AC pumps the brown wire lead is live or common. the blue wire is neutral and the green/yellow is ground. On 12 and 24-volt pumps the red lead is positive and should be connected to the battery plus (+) terminal. The black lead is ground and should be connected to the battery minus (-) terminal. Use T6 AWG wire minimum. Use a fuse to protect the system wiring and components.
Improper duty cycle and/or rapid start-stop conditions caused by undersized spray nozzles will cause the internal thermal breaker (if equipped) to trip. or can cause premature motor failure due to excessive heat.

WARNING
