  • Page 6: Electrical Safety

    Section Safety This machine is an electrical appliance. Care must be taken to reduce the risk of electrical shock. READ AND UNDERSTAND ALL INSTRUCTIONS BEFORE OPERATING THE MX500HE. • To reduce the risk of property damage or injury, repairs to electrical systems should only be performed by experienced technicians.

  • Page 7: Mechanical Safety

    Store the Nautilus MX-500HE with the recovery tank lid open. • Keep Vacuum Inlet Filter clean and check float for proper operation. Do not operate the Nautilus MX-500HE without the Vacuum Inlet Filter in place. Use defoamer to eliminate foam build-up during cleaning and prevent foam/moisture from entering vacuums.

  • Page 8: Vacuum Connections

    Section Vacuum Connections The MX500HE 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. ∗ THIS MUST PERFORMED QUALIFIED TECHNICIAN 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 15m extension cords are supplied with the Nautilus MX500HE. The amperage required by each cord requires that the two cords be plugged into separate circuits: • Cord #1 (Left side) Powers vacuum #1, vacuum #2, cooling fan and the optional waste pump if so equipped.

  • Page 10: Water Supply & Chemicals

    2A. Water Supply & Chemical Mixing– Manual Fill: • Pour up to 12 gallons (45.4 liters) of hot water into the solution tank at the front of the machine. The water temperature cannot exceed 130° ° ° ° F or 54°C. •...

  • 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. •...

  • Page 13: Solution Hose & Pump Priming

    3. Priming the High-Pressure Pump: Once water is in the solution tank, the high pressure pump must be primed: • There is a priming hose included with the machine. Connect the priming hose to the solution outlet – female quick connect on the front of the machine. •...

  • Page 14: Heater & Vacuum Hose

    5. 1750W Heater Operation: To prevent damage to the heater, the heater must have water in it before it is turned ON. Fill solution tank, prime the pump and connect solution hoses before turning heater ON. While the heater allows for maximum operating temperature of approximately 190ºF or 88°C, the temperature of the cleaning water delivered to the tool is dependent on two factors: •...

  • Page 15: Foam Downer

    The Foam Downer is an attachment that allows the vacuum to draw a small amount of defoamer in a constant slow flow into the waste tank of the Nautilus. We recommend using a diluted defoaming solution of four ounces of defoamer to one gallon of water (1-32). Place the draw tube into the gallon of diluted defoamer and open the needle valve one half turn as your starting point.

  • Page 16: Pump-Out System

    8. 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

    9. Pressure Adjustment: To make it easier to check and adjust the pressure, the pressure gauge and the pressure regulator 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.

  • 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

    Accessory Storage Options: The MX500HE is designed to make it easier for the operator to transport the machine and the most common cleaning accessories. Bucket & Sprayer Storage The top of the MX500HE is sized and recessed to hold a five gallon bucket or two one-gallon chemical bottles as well as two 2QT sprayers.

  • Page 28 CLEAN CHEMICAL FEED FILTER & FOOT VALVE: (If so equipped) Part of the optional Auto Fill & Chemical Feed system, the Filter & Foot Valve is on the end of the chemical feed hose that is placed in the chemical jug as part of the chemical feed system. Regularly examine the filter and clean as needed.
  • Page 29 CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the MX500HE, 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 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 Storage Prep and Freeze Protection Procedures: Your Nautilus MX500HE must be protected from freezing. Freezing can cause serious damage to the pump, pump-out, auto-fill float valve, and any other component containing water. If the MX500HE is transported or stored in freezing temperatures, the following procedures should be performed.
