    (see Page 9 for details.) • Do not use the MX3-500 outdoors, in standing water or on wet surfaces. Do not store the MX3-500 in wet conditions. If extractor is leaking, unplug machine power cords from outlets before approaching or touching machine.

  • Page 7: Mechanical Safety

    Store, transport, and use this equipment only in temperatures well above freezing. (32ºF or 0ºC). If you suspect the MX3-500 has been frozen, do not plug in or turn on machine until you are sure it has thawed completely.

  • Page 8: Vacuum Connections

    Section Vacuum Connections The MX3-500 has a unique vacuum system which allows you to connect your vacuums in either parallel or in series. Vacuum connections can be changed quickly, with only a screw driver. While there is debate on which vacuum alignment provides the best extraction, this much is true: •...

  • Page 9: Electrical Supply

    SET UP AND OPERATION 1. Electrical Cords: Two 25’ power cords are supplied with the Nautilus MX3-500. The amperage required by each cord requires that the two cords be plugged into separate circuits: • Cord #1 (Left side) will supply power to vacuum #1, solution pump and cooling fan.

  • Page 10: Water Supply & Chemicals

    16-1/4oz of chemical to each gallon of water.) • The recommended tip for use with the MX3-500 is the turquoise tip with a dilution rate of 256:1. This means that for each gallon of water flowing into the machine, 1/2 ounce of chemical will be added.
  • Page 11 How to Change the Metering Tip: • Remove the chemical feed hose from the barb on the side of the proportioning valve. • Unscrew and remove the old tip. • Screw in the proper tip for your chemical tip and place the hose back on the barb Proportioning Valve Turquoise Tip Dilution 256 - 1...
  • Page 12 Water Supply: • Once the correct metering tip is in place: o Connect the Auto-Fill Water Supply Hose to the water inlet (the male quick-connect on the front of the machine.) o Connect the other end of the hose to a water faucet, and then turn on the water. •...

    3. Connection of Solution Hose: Connect the high pressure solution hose to the solution outlet (female quick connect on the front of the machine). Connect the other end of the hose to the male quick connect on the cleaning tool. When you are ready to start cleaning, turn the solution pump switch to the ON position HP Solution Hose Assembly –...

  • Page 14: Vacuum Hose

    The vacuum connection port on the machine can be either a 2” hose barb or 2” male Flash Cuff. Both are included with your MX3-500. The desired connector can be threaded into the vacuum port on the front of the machine.

  • Page 15: Foam Downer

    The Foam Downer kills foam as waste water enters the machine. Place a container of liquid defoamer on the top of your MX3-500. The vacuum air flow siphons the liquid defoamer through Foam Downer into the vacuum tank, breaking down the foam before it can cause any damage or make a mess.

  • Page 16: Pump-Out System

    6. Connection of Optional Pump-Out Hose: If your machine has the Optional Auto Pump-Out System you may want to connect the Pump-Out Hose. The pump-out hose is a 50’ section of 3/4” garden hose. (Use of smaller diameter hose may reduce flow.) •...

  • Page 17: Pressure Adjustments

    7. Pressure Adjustment: To make it easier to check and adjust the pressure, the pressure gauge and the pressure regulator/unloader are mounted on the control panel on the front of the machine. When the high-pressure solution pump is on and primed, pressure will show on the gauge only while the tool is being sprayed.

  • Page 18: Shutdown Procedures

    Shutdown Procedures: • If using the optional auto-fill system, turn the water supply off before finishing each job. This will allow use of the water and chemical already in the tank, and will reduce the amount of excess water to be disposed of later.

  • Page 19: Accessory Storage

    Bucket & Sprayer Storage The top of the MX3-500 is sized and recessed to hold a five gallon bucket or two one-gallon chemical bottles as well as two 2QT sprayers.

  • Page 27: Maintenance

    Section Maintenance Proper maintenance is required to keep the MX3-500 operating properly, prevent downtime and to extend the life of your equipment. WARNING: Disconnect electrical power before performing any service or maintenance inside machine base or before testing or repairing switches or power cords.

  • Page 28: Warranty

    Inside the recovery tank, on top of the stand pipe, is the Vacuum Shutoff Assembly. It functions to prevent debris and water from being sucked into the vacuum motors. Operating the MX3-500 without the Vacuum Shutoff Assembly or with a poorly maintained assembly will greatly decrease the life of the vacuum motors and will void the warranty.
  • Page 29 CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the MX3-500, build-up of debris in the filter screen of the optional Hydro-Filter II will reduce the vacuum air flow and may cause a significant decrease in water recovery. A torn filter screen will allow debris past the filter and into the recovery tank.
  • Page 30 CLEAN WASTE PUMP-OUT PUMP: (If so equipped) Build-up of fine silt inside the optional Waste Pump can clog the pump even if the pump is not used, so this maintenance procedure should be performed regardless of whether the Waste Pump has been used. •...
  • Page 31 A restricted Pump Inlet Filter can prevent the solution pump from providing adequate pressure for cleaning. A restriction or air leak on the pump inlet hose can also damage the solution pump check valves and plunger Inside View: MX3-500 Solution Tank seals. CAUTION: Before proceeding with this procedure, make sure both power cords are disconnected.
  • Page 32 FLUSH CHEMICAL SYSTEM: (If so equipped) Chemical build-up in the optional Auto Fill chemical system can prevent the system from drawing chemical. • Rinse the chemical system with fresh water (For heavy chemical build-up, a mild acid can be added to the rinse water.) •...
  • Page 33 LUBRICATE PRESSURE REGULATOR O-RINGS: To maintain consistent adequate pressure delivery to the cleaning tool, the o-rings on the stem of the MX3- 500 pressure unloader/regulator must be lubricated regularly. 1. Remove the black knob from the regulator. 2. Unscrew the brass knob assembly from the piston retainer. 3.
  • Page 34 CLEAN RECOVERY TANK DRAIN Debris and sand accumulation in the drain valve can damage the valve or prevent it from closing completely. This will result in dirty water leaking from the valve. Use of the Hydro-Filter and regular cleaning of the recovery tank will help prevent this, but occasionally the drain valve will require cleaning or replacement.
  • Page 35 This will assure that the anti-freeze will be drawn into the proportioning valve. 5. Connect any cleaning tools and solution hoses that will be stored with the MX3-500. Direct tool spray back into the solution tank or into a bucket. Repeat for all tools to be protected.
