• Q. What does a “micron” size mean and what does a “mesh” size mean?
  
  A. 1. Micron: The smaller the micron number the smaller the particle that will pass through the mesh therefore, the finer the screen needed.
  2. Mesh: the higher the mesh number the more screen per square inch and the higher the mesh number the smaller the particle that can pass through the screen.

Choosing An Injector

• Q. What chemical will be injected?
  
  A. This is important because some chemicals and/or concentrations affect the injector material differently. If you have any doubts about the chemical compatibility of the injector to the chemical you are using, contact Dosmatic (800) 344-6767, (972) 245-9765 Or info@dosmatic.com ,or your nearest Dosmatic distributor. Once the above factors are known, you may use the specifications listed for the injector models to choose the most effective model for your application.
• Q. I have decided Dosmatic will be my injector supplier. What model is best for my application?
  
  A. Before choosing an injector you must first determine:
  -The line water pressure (5-140 psi, depending on model)
  -The water flow – gallons/liters per minute of total flow into the injector.
  -To determine this, work backward from the nozzle, nipple, sprinkler head or other method of delivery in place.
  -Measure or calculate the flow rate for each nozzle, dripper, etc.
  -Multiply this by the number of nozzles, drippers, etc. that will be run at one time. This is your maximum flow rate.
  This rate should not exceed the rate specified for the model you are using.
  -The water source - city water, well, lake, etc. (this aids in filter set-up)
  -The diameter of water line feeding the injector:
  MicroDos models are standard with a ½” thread
  -A12 & MiniDos models are standard with ¾” NPT & BSP male threads
  -A15, A20, A30, DP 20, and DP30 models are standard with either 5/8” hose or 1” NPT & BSP male threads.
  -The SuperDos 15, SuperDos 20, SuperDos 30, and the SuperDos 20IA are standard 1” NPT & BSP male threads
  -The SuperDos 45 models are standard with 1 ¼” NPT & BSP male threads.
  -The TurboDos100 models are standard with a 2” flange
  -The TurboDos200 models are standard with a 3” flange
  
  If the standard connections of the model needed do not fit the standard diameter of the water line, additional adapters can be ordered. See your local plumbing supply or contact Dosmatic’s Customer Service Department at (800) 344-6767 for availability.

Use

• Q. How do I adjust the ratio setting and what do the numbers mean?
  
  A. To adjust the ratio setting: MiniDos 10%, SuperDos 15, 20, 30 or 45 A12-1%, A15, A20, A30, or A40 model Pull out the upper pin and rotate the ratio adjuster until the desired setting is directly above the top edge of the ratio adjuster, do not remove stainless steel clip when under water pressure! If you are adjusting the: MiniDos 20% desired setting, read the bottom of the cylinder. If you are adjusting the: MicroDos 0.8%, 2% or 5% MiniDos 0.4%, 1%, 2.5% or 5% A12 2.5% or 5% TurboDos 100 or 200 Rotate the ratio adjuster until the lines of the desired setting are lined up with the white marker in the center of the ratio adjuster.
• Q. Ratio and Percentage settings on the injector:
  
  A. You will notice numbers appear on the left and right sides of the ratio sleeve on most models (except the MiniDos 20%). The left side lists an injection percentage, and the right side gives the ratio of solution being injected to water passing through the unit. These numbers are really the same. For example, the number on the left side is 2.5 which equal 2.5%. The equivalent to the right side is the number 40, which is the denominator of the ratio 1:40. The number 1 divided by 40 equals .025 or 2.5% and so on. Remember, when determining the setting for your ratio adjuster; always use common units of measure for both solution and water – e.g. gallons to gallons or ml to ml.
• Q. Do I need to calibrate my injector?
  
  A. Yes, because all injectors are mechanical pieces of equipment and wear on parts is inevitable over time (depending upon the amount of use). EC(electrical conductivity) or TDS (total dissolved solids) meters can be used to verify accuracy. Regular maintenance of the o-rings and dosage piston (wear parts) will help prevent deviations from the selected dosage.
• Q. Do I need to bleed or purge the air in my injector?
  
  A. No. There should be no need to bleed the injector, as the water flow will force air through the line. When a tank feed, low pressure or low flow system is installed with the injector being the highest point in the system; a low flow might cause air to be trapped in the line. Operate injector at higher flow until air is out of the system.
• Q. Can I inject two or more chemicals at the same time?
  
  A. Combining two chemicals in the solution tank can produce a chemical reaction that could damage the injector, or even an explosion resulting in personal injury. To use two or more chemicals at the same time, you can install injectors in a series. When installing in a series, you should use a remote injection kit to protect the injectors. If a remote injection kit is not used with a series installation, then the first chemical solution becomes the inlet water for the second injector, and, depending upon the chemical, this could damage the second (or subsequent) injector motors. Click here for a diagram of a typical series installation.
• Q. Can I use hot water to dissolve my chemical?
  
  A. When using a water-soluble chemical, make sure it is thoroughly dissolved before opening the inlet water and starting the injector. You may dissolve the chemical in hot water, if necessary and if the chemical will not be damaged, but allow the water to cool before using. Some chemicals may be damaged with hot water so be sure to check with your chemical manufacturer before adding hot water. Failure to thoroughly dissolve the chemical being injected will cause premature wear to the dosage piston and the cylinder.
• Q. Is back pressure always required?
  
  A. Yes, the Dosmatic injectors require that the outlet line always be under pressure while in operation. Under normal operating conditions a minimum of at least 3 PSI pressure is required on the outlet or solution can siphon through the injector during operation and cause erratic ratio feeding. The minimum of 3 PSI is required at all times, even when water is flowing, to properly seat the Check Valve (# 13 in your parts list), and prevent siphoning or over feeding. Any pressure from 3 PSI up to 85 PSI is acceptable (depending on model).

Installation

• Q. I just received my unit. What are some of the first things I should do?
  
  A. Read your installation manual! If you did not receive one with the unit click here to download or call (800) 344-6767 and ask for Customer Service, or send your inquiry by e-mail to info@dosmatic.com. Be sure to remove the red caps at the inlet and outlet openings and at the suction tube fitting opening. Each unit is shipped with a little water in it, as it is tested before shipping. The red caps prevent leakage during shipment, but must be removed prior to installation.
• Q. What tools will I need to install my injector?
  
  A. When installing into a PVC line you may need: pipe cutters, pipe wrench, PVC glue primer, Teflon tape and your fittings.
• Q. What additional equipment is required for a proper installation?
  
  A. Dosmatic recommends that you install a 140-mesh/104 micron in-line water filter in front of your injector. Depending on your water condition, it may be necessary to install larger mesh filters in series between the water source and the 140-mesh/104 micron filter. A back-flow preventer is required by all city ordinances to prevent back up of solutions into drinking lines and potable water supplies. An anti-siphon valve is recommended to prevent solution from being siphoned out when the upstream valve is shut off. The anti-siphon valve must be installed 6” above the highest downstream piping. You should always have a way to take the unit off-line for maintenance or storage when not in use. A by-pass set-up will allow you to do this. You may also want to install pressure regulators and gauges in your system. An EC (electrical conductivity) meter or TDS (total dissolved solids) meter is also helpful to verify the accuracy of the unit on a monthly basis. A water hammer arrester is highly recommended if you are operating quick closing, solenoid valves, pneumatic valves or even hand-operated ball valves on your watering system.
• Q. What water line temperature and pressure should I maintain?
  
  A. Install the Dosmatic injector in a cold water line - no more than 100 degrees Fahrenheit or 38 degrees Celsius - with a water pressure applicable for the model you are installing. Pressure should be regulated to the lowest pressure required for final delivery. Water pressure greater than recommended can cause permanent damage to the injector. (Refer to the specifications for the model you are installing)
• Q. Why is a water filter important?
  
  A. A water filter prevents debris such as sand from entering the motor of the injector which can cause premature failure in the injector. This is especially important if your water source is from a well or pond. Install a 140 mesh/104 micron filter or finer on the inlet side of the injector. Dosmatic carries the Twist II Clean filters that can be ordered with your injector. Failure to use an inline filter will void any warranty.
• Q. What are the arrows on the injectors for?
  
  A. The arrows on the lower injector body indicate direction of water flow and to help assure proper installation. Install: All models (except A12 model) the arrow points in the direction of the water flow. A12 injectors, the arrow is on the inlet side.
• Q. How high above the solution container can I install my injector?
  
  A. Dosmatic recommends no more than a 15’ vertical hose and no more than a 50’ horizontal hose from the solution container to the injector (depending on viscosity).

Maintenance

• Q. What preventative maintenance do you suggest?
  
  A. Dosmatic suggests that you always keep inlet water line and solution filters installed and clean. The solution container liquid should also be kept clean and covered. Never operate the injector at a water pressure or water flow outside the recommended range for the model installed. Dosmatic recommends that you change the o-rings and dosage piston (wear parts) at least once a year, preferably every six months, depending upon usage. Rinse or flush out unit periodically with fresh water by injecting clear water for 10-15 minutes. Long term storage; immerse the entire unit in water, place in a area that is above 32 degrees Farenheit/0 degrees Celsius.
• Q. My solution filter keeps clogging. Can I just remove it?
  
  A. The solution filter on the suction tube should not be removed and should be kept at least 2” from the bottom of the solution bucket or tank to prevent debris from clogging the filter and stopping the injector from functioning. If the filter is clogging, check to be sure that it is at least 2” from the bottom. If the solution is not thoroughly dissolved, your filter may become clogged. Check to be sure that your entire chemical is dissolved. You may need to add an agitator to keep the solution from settling. Keep the solution container covered so that debris does not contaminate your solution and clean the solution container occasionally to prevent dirt and scale build-up.
• Q. What lubricant should I apply to the o-rings of my injector?
  
  A. Dosmatic injectors are shipped with a thin coat of silicone around the seals as a precautionary measure before the injector is put in use. Reapplying silicone is not necessary unless an extended storage period is anticipated. Petroleum based lubricants such as Vaseline®, baby oil, WD 40®, motor oil, etc. should never be used on the O-rings or any part of the injector as this can cause a chemical reaction, damage to the o-rings, or particles to adhere and clog or damage the injector. Call Dosmatic at (800) 344-6767 or e-mail info@dosmatic.com, or contact your nearest distributor if you have any questions.

Use

• Q. Can I use one injector for two tanks?
  
  A. Yes. The Turbodos can be used for multiple tanks with the appropriate valves on the discharge of the injector.
• Q. Can the injector run backwards?
  
  A. Yes. However, due to the patented rotary design premature wear is likely if operated backwards.
• Q. What are the benefits of using the TurboDos rather than manually splash blending or manually pouring my additive directly into my storage tank or transport truck?
  
  A. Using the TurboDos to inject fuel treatment additives eliminates the liability concerns of physically having to climb on top of the tank to manually pour for each fuel delivery. It ensures the proper injection ratio with every load. This allows for the optimal benefits of the additive, while eliminating costs due to waste. It offers maximum benefit of additive to fuel while eliminating wasted chemical cost. The use of drums, totes or tanks eliminates the need to inventory large quantities of smaller containers. With an adjustable lower end it allows you to change injection ratios between your summer and winter blends.
• Q. Can this injector be used for Diesel, Jet Fuel, AVGAS, or Gasoline?
  
  A. Yes.
• Q. Can this injector be used for Biodiesel?
  
  A. Yes. The use of the injector with Biodiesel is dependent on the desired injection ratio in regards to the unit’s operating specifications and viscosities. The injector, along with the additive suction hose, may be required to be insulated in colder climates.

Installation

• Q. How do I install my injector?
  
  A. There are a number of ways to install the TurboDos. The TurboDos has an ANSI 3” flange on both the supply and discharge of the injector. The injector can be plumbed directly into the supply line (above ground tank, transport truck, bulk storage facility) or can be purchased with a tote or drum stand for mobility. For sites with limited space piping configuration, a mobile unit is available.
• Q. Is the installation difficult?
  
  A. The installation varies for each application. Dosmatic will provide suggested installation procedures with the proper amount of information.
• Q. Can I install the injector horizontally, vertically or inverted?
  
  A. Yes. Due to the patented rotary design the injector is very versatile when it comes to installation. Dosmatic recommends a vertical installation whenever possible, but the injector can be installed horizontally and inverted as well.
• Q. Should I install the TurboDos higher than the additive storage (drum or tote) tank? Why?
  
  A. Yes. Due to fluid dynamics and physics, if the injector’s lower end is lower than the end of the suction hose (in the drum or tote) then siphoning will occur. The accuracy of the injection rate will be compromised if siphoning occurs.
• Q. Can Dosmatic assist in recommending proper installation techniques?
  
  A. Yes. With appropriate photographs of the proposed installation site along with diagrams, Dosmatic should be able to provide you with appropriate installation suggestions along with diagrams. Contact us (800) 344-6767 or send electronics photos to info@dosmatic.com
• Q. Do you recommend installing a By-Pass when installing the injector?
  
  A. Yes. A 3 valve by-pass is recommended with all installations for supply lines.
• Q. Why do you recommend a By-Pass?
  
  A. As with any mechanical apparatus the potential for failure exists. Dosmatic recommends a By-Pass for this reason. When installing at a bulk storage facility where there is one dedicated line used for supply and discharge, a By-Pass is required to prevent double additising.

• Q. Can I install my TurboDos in cold or hot climates?
  
  A. Yes. The TurboDos has been installed in climate ranges from -60F to 100+F
• Q. Why is there a minimum flow requirement?
  
  A. Due to the patented rotary design, the TurboDos requires a minimum volume to operate the internal components. 40GPM (TurboDos200) 20GPM (TurboDos100)
• Q. Why is there a minimum PSI requirement?
  
  A. Due to the patented rotary design, the TurboDos requires a positive pressure to operate the internal components. 30PSI (TurboDos200) 20PSI (TurboDos100 )
• Q. What happens if I exceed the maximum flow?
  
  A. Exceeding maximum flow has the potential of causing premature wear on the internal components of the injector. Premature wear could have an adverse effect on the accuracy of the TurboDos.
• Q. What happens if I exceed the maximum PSI?
  
  A. Exceeding maximum pressure has the potential of causing premature wear on the internal components. Premature wear could have an adverse effect on the accuracy of the TurboDos
• Q. What are the vertical and horizontal head limitations?
  
  A. Maximum vertical lift (head) is 15’-0”. Maximum horizontal lift (head) is 60’-0”. Note: Based on a Specific Gravity 1.0 (Water)
• Q. What is the weight of the unit?
  
  A. 18lbs (30lbs packaged) – 8.2kg (13.6kg packaged)
• Q. How do I determine which model is the one I need?
  
  A. Determining the appropriate size of the TurboDos is based on the following criteria: • Maximum flow and pressure of the fuel passing through the injector. • Desired injection rate of additive. There are 3 lower ends available. • Injecting one or two different additives? The Turbodos has the capability of injecting two different additives simultaneously at two different injection rates • Installing on a supply or discharge line(s).
• Q. How is it non-electric?
  
  A. Due to the patented rotary and crank arm assembly the unit operates solely on the fuel passing through the injector.
• Q. Does the accuracy of proper injection depend on flow and/or PSI?
  
  A. No. Due to the patented rotary design the injector is a positive displacement injector. Note: If you exceed the maximum flow or pressure requirements there is a potential for inaccuracies with the injection rate.
• Q. Is the injector mobile?
  
  A. Yes. Using the TurboDos in conjunction with the tote or drum stand allows you to move the injector to and from various locations. The injector can also be used on a transport or fuel wagon with camlock fittings to allow for ease of mobility.
