Safety, maintenance and repair, warranty, and factory information is also provided. Please read this manual completely before proceeding. Observe safety protocols and heed all warnings and precautions.Model NumberingMicroTron™ Series A pump model numbers define the output, pressure and control functions present on a particular pump. Your pump may be supplied with one or more of the options described in this manual. To determine what features apply to your pump, check the model number label located on the pump.Model Number Example A 1 30 X 1 – K V C 1 - SPressure Rating 1 = ??0 and ?50 psi 2 = 250 psiGallon Per Day Rating 30 = 30 gallons per day at ??0 psi 15 = ?5 gallons per day at ?50 psi 17 = ?7 gallons per day at 250 psiControl Options X = Strokes per minute or hour (standard) M = 4-20mA Input T = Selectable Timers - Pulse, 28-Day, Recycle Voltage 1 = ?20 volt - 50/60 Hz - .35A with USA plug (standard) 2 = 240 volt - 50/60 Hz - .65A no plug 3 = 240 volt - 50/60 Hz - .65A with specified plug 4 = ?2 volt dcPump Head Material K = Kynar S = StainlessSeat Material V = Viton (standard) F = Teflon H = HypalonCheck Ball C = Ceramic (standard) D = Ceramic single on discharge S = StainlessTubing Connections 1 = 3/8” PE, models up to ?50 psi (standard) 2 = ¼” PE, 250 psi models (standard) 3 = 3/8” PE on 250 psi models P = ¼” MNPT V = 3/8” Clear flexible suction tubingSpecial Options E = External Stop H = Hall effect water meter wire (5VDC); only with control option T S = 3-function injection valve R = No stroke length adjustment knob4II. Unpacking The MicroTron™ pump has been shipped as a complete package, ready for installation. If the shipping carton shows any signs of damage, notify the shipping company immediately upon receipt. Advantage Controls cannot be held responsible for damage from shipping. Unpack the carton and insure the following items are present: ?. Metering pump 4. Injection fitting 2. Suction, discharge and priming tubing 5. Instruction manual 3. Foot valve and weightIII. Safety Considerations NOTE: All MicroTron™ pumps are primed with water before leaving the factory. If the solution to be pumped is not compatible with water, disassemble the pump fluid end before use. After disassembly, thoroughly dry the pump head, valves, and seals before pump is reassembled and used. A. Chemical Compatibility MicroTron™ metering pumps are designed to work with most liquid chemicals depending upon your pump’s liquid end materials of construction. A chemical resistance chart is available for determining specific compatibility with a wide variety of chemicals. If you have further compatibility questions, contact Advantage Controls service department at ?-800-743-743?. B. Safety and Preparation Always wear the proper protective clothing and gear when working around chemicals and chemical metering pumps. Safety glasses, gloves, and aprons are critical in preventing accidental exposure to dangerous chemicals. Liquids under pressure can present a special hazard when a line or seal is punctured resulting in the spraying of chemical many yards away. If a chemical spillage occurs, consult the Material Safety Data Sheet (MSDS) for specific instructions regarding the chemical being used.IV. Installation A. Location Select a mounting location convenient to the chemical supply as well as a source of power for the pump. Do not install the pump in a location where the ambient temperature exceeds ?20 degrees F (50oC). Higher temperatures will affect the output as well as the useful life of the pump. While the MicroTron™ pump is suitable for most outdoor installations, do not use the standard poly tubing in direct sunlight. If you must mount pump in direct sunlight or under bright fluorescent lights use ultra-violet resistant tubing, consult your distributor or the factory. Accessory item R00225 (plastic mounting bracket) is recommend for a secure installation.5B. Electrical?. The Standard MicroTron™ pump has a voltage regulated internal power supply capable of operating in the range of approximately 95 to ?35 VAC. Use a supply voltage of ?00 to ?20 VAC for best results. The 3-wire grounded plug must be used in a 3-wire wall plug.2. With a 240 volt option, the MicroTron™ pump has a voltage regulated internal power supply capable of operating in the range of approximately ?95 to 260 VAC. Use a supply voltage of 2?0 to 250 VAC for best results.CAUTION: Never remove ground wire from plug C. Plumbing 1. Tubing ConnectionsThe MicroTron™ pump uses carefully matched components to achieve a predictable metering output. This predictability can only be maintained if all fitting sizes remain unaltered. Do not attempt to reduce tubing size. All tubing connections should be double checked to insure against leakage. If hazardous chemicals are being pumped, use shielding around discharge tubing. NOTE: When cutting lengths of tubing for your installation, ensure a clean, square cut. Use short lengths of tubing and as few connections as possible. 2. Tubing NutsDo not overtighten the tubing connectors. Tighten the fittings no more than ?/4 turn after the fitting contacts the seal. Hand tighten only. Do not use a wrench or pliers as they may damage the fittings. Do not use Teflon tape except on NPT fittings. Be sure to observe applicable local plumbing codes.WARNING: Clear flexible tubing is not intended for pressurized use.3. Tubing Connections3/8"1/4"TUBING MUST SLIP OVER NIPPLE1/4" TUBINGADAPTERIMPORTANT THE END OF THE TUBINGMUST EXTEND 1/4" BEYOND ADAPTOR6 4. Suction Lift vs Flooded Suction ApplicationsSuction Lift InstallationMount the MicroTron™ pump around the top of the solution tank, not to exceed 5 feet from pump to bottom of tank.Flooded SuctionThis installation is recommended for very low outputs, solutions that gasify and/or high viscosity solutions. Priming is easier and loss of prime is reduced. Failure of the pump diaphragm or rupture of the solution tubing can cause loss of solution in the tank.Suction lift Flooded Suction Not recommended 5. Wall MountingThe fluid end portion (head assembly) of the pump is set up to accommodate mounting of the pump to the chemical container, either as a flooded suction, or a suction lift. The pump head must be kept in a vertical position for proper operation. The head can be removed and rotated 90o if needed to keep the inlet and outlet valves in a vertical position. 6. Foot valve installationA weight is provided to hold the tubing and foot valve in a vertical position at the bottom of the tank. Do not allow the foot valve to lay horizontally in the chemical container. This defeats the action of the valve and causes the pump to lose prime. Keep suction tubing reasonably short and avoid high spots or bends. 7. Injection valve installationThe injection valve is designed to prevent a back flow and to inject chemical into the line. To work properly, this valve must be mounted within 45 degrees of vertical (see drawing). One end of the injection valve is ?/2” MNPT. Install this end into the piping system. Use Teflon tape on this fitting only. Connect the pump’s discharge tubing to the opposite end of the injector. Do not use Teflon tape or joint compound on this fitting. Connect tubing between this fitting and the pump discharge fitting at the pump head.7 80 VariationAcceptable Flow DO NOT Use Teflon TapeOn Machine Threads USE Teflon Tape On These Threads Only Injection Check ValvePipe Cross Section 8. Optional Three Function Valve.Anti-siphon feature allows metering of liquids “down hill” or into the suction side of a circulating pump. It provides protection against an accidental application of suction pressure at the fluid injection point. Its Teflon coated diaphragm provides a positive anti-siphon action.Back pressure function permits metering into atmospheric discharge (open container) without overpumping.Line check permits removal of discharge tubing without release of system fluid. 9. Priming / Degassing Valve ConnectionConnect the clear poly tubing to the outlet of the bleed or priming valve. Position the free end of this tube in the chemical container. Standard head configurations include a priming valve built into the head. Clear poly tubing should be connected to the outlet of this valve, the other end of the tube should be placed in the chemical container above the fluid level.V. Start-Up A. Front Panel Description8020304050607090100POWER PULSEPress ENTER to testPress MENU to access settingsMENUENTERAll Model R pumps come with the following standard panel features:• ?x?6-backlit LCD display• On/Off power indicator light• Pulse or Stroke indicator light• Up and Down arrow keys for setting adjustments• MENU key to enter and exit pump set-up• ENTER key to save desired adjustmentsNOTE: When installation is made into a line with zero pressure or when pumping into an open vessel, use the optional three function injection valve which provides back pressure and anti-syphon capabilities.8 B. Run Mode Explanation The readout will display one of two modes, Run mode and Set-up mode. Run mode is displayed only while the pump is in normal operation. The display will show the pump speed setting.Manual activation of the relay output and pump stroking can be activated by pressing the ENTER key while the pump is in the run mode. This will manually activate both functions of the unit for 3 minutes. After three minutes the unit goes back to automatic.If the ENTER key is pressed during the 3 minute test, it will revert to automatic. C. Set-Up Mode ExplanationTo enter Set-up mode, press MENU. Notice that a cursor appears on the screen signifying that an adjustment can be made. To change the figure above the cursor press the UP or DOWN keys until the desired setting appears, then press ENTER to advance. Continue pressing ENTER to toggle past the other displays. When all settings are made, press MENU to return to run mode, and save settings. D. Password Protection Option T allows for a built in four-digit password to prevent unauthorized changes. Entering Setup Mode when a password has been set - Press Menu and enter the correct four digit password using the up and down arrow keys followed by Enter. Once the password has been entered correctly the Setup Mode menus can be accessed. A code of 0000 disables the password. Set a new password by pressing the Menu key to enter the Setup Mode. Press ENTER until the display shows “Password: 0000” then use the up and down keys followed by the ENTER key to set each of the four digits to the desired value. E. Priming the Pump 1. Settings Plug in pump, set stroke knob to ?00%. 2. Priming/Bleed valve If fluid begins moving up suction line while pump is operating, no further priming is required. If fluid is not moving, open bleed valve approximately one turn until fluid begins to move. When suction line fills, close bleed valve. Do not over tighten bleed valve. Damage may occur. 3. To prime the Advantage A pump, simply press the ENTER key while the pump is in Run mode. This allows the pump to stroke at the maximum STROKES/MIN setting. F. Adjusting Feed Rate The A pump allows for an exact number of strokes to be set and read on the front panel LCD meter. It is adjustable from 0 to ?25 strokes per minute (0 to ?60 for 55 GPD). In addition, for applications requiring very low outputs the speed can be set in strokes per hour from ? to ?25.9 G. Stroke LengthThe stroke length can be adjusted on all MicroTron™ pumps. This adjustment is a mechanical adjustment made using the large knob on the control panel. To avoid damage to the pump, this adjustment should only be made while the pump is running at a high stroking rate.Always start adjusting your pump’s output down by reducing the pump’s stroking speed or frequency. By leaving the stroke length as long as possible you decrease any chance of loosing prime. H. Calculating OutputA pump’s output per minute can be determined by dividing the maximum rated gallons per day by ?440 (minutes per day). For example, a 30 gallons per day (gpd) pump at a maximum stroke length and speed setting of ?25 strokes per minute (spm) will pump 0.000?67 gallons per stroke (gps). 30 ÷ 1440 = 0.0208 gpm ÷ 125 spm = 0.000167With this value and the pump’s speed setting (strokes per minute) you can calculate your pump’s output at it’s rated pressure. A 30 gpd pump set at 50 strokes per minute: 50spm x .000167gps x 1440 (minutes per day) = 12.02 gallons per dayReducing the stroke length will reduce the pump’s output again. If the example pump above had it’s stroke length reduced to 50% the ?2.02 gallons per day output is reduced to 6.0?. (example: ?2.02 gpd x 0.50 = 6.0? gpd)A higher product viscosity will reduce the output. Pressures lower than the pump’s rating can increase the output.VI. Control Options A. Standard Control (Basic A Pump) - See Menu Map on Page 10 Pumps continuously with speed and length adjustments. B. 4-20mA Input (Option M) - See Menu Map on Page 12 Option M allows the pump to accept a 4-20mA signal input to control the pump’s stroking rate or speed from an external control device. The pump can be programmed for number of strokes per minute at two milli-amps points on a 4-20 scale. The maximum setting is ?25 strokes per minute. C. Selectable Timers 1. Recycle Timer - See Menu Map on Page 11 The recycle timer allows the pump to run based on set cycle times. The on time is adjustable from ? second to 99 minutes and 59 seconds. The off time is adjustable from ? minute to 99 ?0hours and 59 minutes. Ex. An on time of ?5 minutes and an off time of ?5 minutes will cycle the pump on ?5 minutes and off ?5 minutes repeatedly. 2. Pulse Timer and Flowmeter Input - See Menu Map on Page 11 Pulse timer allows the pump to run based on signals from an external dry contact switch closure. There are four selections for a pump with this option selectable on the MENU page EXT= which is short for external. Press ?? to select the desired external pulse function from the selections below. Press the ENTER key to set the desired pulse function. With screen showing Timer: MLTIPL BY the pump strokes based on multiplying each incoming pulse by ? to 9999. With the screen set for Timer: DIVIDE BY it strokes based on dividing each in coming pulse. For example, if the pump is told to divide by five it will count five incoming external pulses and then stroke one time. The pump will store strokes (a maximum of 65,000 divided by the set multiply factor) to be made if contacts come in faster than the pumps stroking. If the stored number of strokes exceeds the maximum any additional strokes are lost. 3. Biocide or Event Timer - See Menu Map on Page 11 Biocide or event timers allow the pump to feed chemical based on a 28-day timer for the daily, weekly, or monthly addition of chemicals. The unit has four programmable timers labeled P?, P2, P3, and P4.VII. Set-Up Menus125 Strokes/Min Reset Counter?

Trouble ShootingPROBLEM CAUSE REMEDYPump does not achieve or maintain primeAir trapped in suction lineFoot valve contaminated or improperly installedExcessive liftSuction fittings not properly tightenedWorn or contaminated check valvesSplit or pinch in suction tubeLow chemical levelStraighten suction line so as to eliminate high spots.Inspect foot valve screen and assure that foot valve is in a vertical position below fluid level.Maximum suction lift is 5 feet with water or fluids of similar specific gravity; less with heavier liquids such as acids. Mount pump in a lower position relative to the chemical container.Check fittings. Overtightening may cause restriction. Conversely, if any leakage occurs, pump will suck air and fail to prime.Inspect check valves in fluid end for cleanliness. Clean or replace as necessary.Inspect suction tube through its full length to assure that there are no splits at the connections or other restrictions. Move any objects or equipment which impinges upon suction tube or reroute as required to assure a smooth transition from foot valve to pump.Check fluid level in chemical supply tank.Insufficient fluid Stroke adjustment set too lowWorn or contaminated check valvesObstruction in suction lineClogged foot valve screenOutput (system) pressure too highDiaphragm worn or tornElectronic failureCheck operation of stroke limiter knob. If pump delivers too low adjustable rate, check settings.
