Overview

The Air Level Master™ is a float valve system that regulates the activation of Satellite Mixing Stations (sold separately) to automatically maintain a constant supply of ready-to-use chemical solution in a paired day tank (sold separately). When the solution in the tank drops below a pre-set level, the float valve will open to allow compressed air to flow through and activate one or more Satellite Mixing Stations to quickly replenish the solution.  The system cycles continuously.

Safety & Operational Precautions

  • When connecting to a potable water supply follow all local codes for backflow prevention.
  • For proper performance do NOT modify, substitute nozzle, hose diameter or length.
  • Manufacturer assumes no liability for the use or misuse of this unit.
  • Wear protective clothing, gloves and eye wear when working with chemicals.
  • Always direct the discharge away from people and electrical devices.
  • Follow the chemical manufacturer's safe handling instructions.
  • NEVER mix chemicals without first consulting chemical manufacturer.

To Install (refer to diagram on next page)

Backflow prevention: Follow all local codes for preventing backflow into the water supply before installing / operating equipment.

  1. Position Air Level Master Tank on a level surface.
  2. Carefully unpack the Air Level Master lid / float assembly and thread on to tank opening.  Ensure that the float(s) are hanging freely.
  3. Mount the High Flow Satellite Mixing Station unit(s) to a suitable surface above the chemical supply to prevent siphoning.
  4. Connect the discharge hose(s) as shown in the diagram.
  5. Flush any new plumbing of debris before connecting water. If water piping is older, or has known contaminants, install a water filter.
  6. Connect the water supply to the Mixing Station unit(s).
  7. Push lock 5/32 poly-flow tubing to the tube lock fitting on the Level Master and to the wall mount Mixing Station solenoid(s)
  8. Connect a clean, dry compressed air supply to the Level Master unit.
  9. Connect the tank discharge hose barb to a pump or other dispensing mechanism using a suction tube.

Set the chemical dilution ratio by threading one of the color coded metering tips into each chemical check valve. See chemical labels for dilution ratio recommendation or consult your chemical supplier.

  • For the strongest dilution ratio do NOT install a colored metering tip.
  • The dilution ratios in the metering tip chart are based on water thin chemicals with a viscosity of 1CPS.
  • Thicker chemicals will require a larger tip than the ratios shown in the chart.
  • Application results will ultimately determine final tip color.
  • Select the tip color that is closest to your desired chemical strength and thread it into the tip holder. DO NOT OVER-TIGHTEN.
  • Push the chemical tube over the check valve barb and place the suction tube in the chemical concentrate.
  • If necessary, cut suction tube(s) to length before attaching suction strainer.

To Operate

  1. With the Air Level Master assembly securely attached to an empty tank, gravity will cause the float valve to automatically sit in the "down" position.  The float valve is now open.
  2. Completely open the air inlet ball valve to activate the Satellite Mixing Station(s) and begin filling the tank with diluted solution.
  3. When the solution in the tank reaches the fill level, the float will rise and shut off the air flow to the Satellite Mixing Station(s).  This will cause the solenoid on the water inlet to close and deactivate the Satellite Mixing Station(s).

NOTE: The fill level is pre-determined by the length of the "push rod" attached to the float, which is intended to be used as provided.  If necessary, the float can be lowered 1/2" by partially unscrewing it from the push rod.

  1. System is now ready for use and will maintain the solution level until the inlet ball valve is manually closed.
  2. Make final metering tip adjustments to the Satellite Mixing Station(s) based on application results.

Troubleshooting Guide
Problem Possible Cause / Solution
StartupMaintenance
A) Mixing station will not draw chemical.
B) Dilution too strong.
C) Dilution too weak.
D) Primary float will not activate (does not fill)
E) Primary float valve will not turn off (overfills or triggers secondary fail-safe float valve on double-float models)

Possible Cause / Solution
StartupMaintenance
  1. Air inlet ball valve not completely open
    • Completely open air inlet ball valve.
  2. Metering tip too large or no tip installed
    • Install smaller metering tip.
  3. Not enough chemical
    • Install a larger metering tip.
  4. Chemical tube not immersed in chemical or chemical depleted.
    • Immerse tube or replenish.
  5. Water pressure too low or water temperature too high
    • Mixing station requires 25 PSI water pressure, see requirements.
  6. Air pressure to Level Master too high
    • Install an air pressure regulator in-line before the Level Master if air pressure exceeds 80 PSI.
  7. Level Master body is not level
    • Install the Level Master on an even surface where the body (injector) is level to the horizon. Ensure that the Level Master will not become unbalanced as it fills.
  8. Secondary fail-safe float has been triggered (double-float models only)
    • Manually reset the secondary fail-safe float valve (refer to operation instructions)
    • Inspect the primary float assembly before resetting the secondary float valve.  If necessary, troubleshoot the primary float assembly.







 

Float hanger seated correctly
  1. Chemical strainer or metering tip blocked
    • Clean or replace chemical strainer and/or metering tip.
  2. Chemical tube stretched where tube slides over metering tip holder or pin hole/cut in tube (sucking air)
    • Cut off end of tube or replace tube.
  3. Vacuum leak in chemical pick-up connections
    • Tighten the connection.
  4. Water strainer screen clogged
    • Clean the water strainer screen.
  5. Physical blockage or interference is preventing the float from rising or falling
    • Ensure that the tank is on a level surface.
    • Ensure that the float, push rods, and metal clips are hanging freely without any interference.
    • Do not modify the float assemblies.
  6. Float valve parts are dirty or defective
    • Clean or replace the affected parts (may require careful disassembly, refer to parts diagram).
    • Ensure that all parts are free of rust, grease, etc.
    • Depending on the chemical and on-site variables, regular cleaning and/or replacement may be required.
  7. Float valve diaphragm stretched out or damaged
    • Replace the float valve diaphragm.
  8. Chemical build-up or scale may have formed in the injector body causing poor or no chemical pick-up
    • Follow Preventive Maintenance instructions below, using hot water and/or descaling acid.  When there is no draw at all, carefully remove fittings and soak entire body in descaling acid.
  9. Water solenoid failed or air is turned off
    • Replace solenoid
    • Ensure air inlet ball valve is completely open
  10. Upward force has unclipped hanger from magnet holder
    • Carefully remove float housing and align wire hanger to grooves in magnet holder.
    • Pull down on wire hanger until you hear a sharp 'click' after the normal activation sound.
    • Wire hanger must be fully seated in magnet holder grooves, as shown on LEFT.
