Years of experience, engineering, and planning have gone into the design and manufacturing of the Nautilus Extreme MXE-500. We take a great deal of pride in the Nautilus Extreme MXE-500; our goal is no less than your complete satisfaction.
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 MXE-500. • To reduce the risk of property damage or injury, repairs to electrical systems should only be performed by experienced technicians.
Store the Nautilus Extreme MXE-500 with the recovery tank lid open. • Keep Vacuum Inlet Filter clean and check float for proper operation. Do not operate the Nautilus Extreme MXE-500 without the Vacuum Inlet Filter in place. Use defoamer to eliminate foam build-up during cleaning and prevent foam/moisture from entering vacuums.
Section Vacuum Connections The Nautilus Extreme MXE-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, without tools. While there is debate on which vacuum alignment provides the best extraction, this much is true: •...
SET UP AND OPERATION 1. Electrical Cords: Two 25’ power cords are supplied with the Nautilus Extreme MXE-500. Cord #1 powers vacuum #1, the Solution Pump and the cooling fan; Cord #2 powers vacuum #2 and the waste pump if so equipped. The amperage required by each cord requires that the two cords be plugged into separate circuits: •...
16-1/4oz of chemical to each gallon of water.) • The recommended tip for use with the Nautilus Extreme MXE-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. Priming the High-Pressure Pump: Once water is in the solution tank, the solution 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. •...
With the proper cuff attached to the 25’ Vacuum Hose, the 25’ vacuum hose is then connected to the vacuum connection port on the Nautilus Extreme MXE-500. The other end with the 1-1/2” cuff is connected to the cleaning tool.
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.
7. Connection of Pump-Out Hose: The pump-out hose is a 50’ section of 3/4” garden hose. (Use of smaller diameter hose may reduce flow.) • Remove the cap from the pump-out outlet fitting on the back of the machine. • Connect the pump-out hose to the outlet fitting. •...
7. 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.
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.
Optional strap for larger wands available Other Tool & Hose Storage Each side of the Nautilus Extreme MXE-500 has a set of molded in threaded inserts to which holders can be attached to hold other accessories or supplies making it much easier to move around.

Section Maintenance Proper maintenance is required to keep the Nautilus Extreme MXE-500 operating properly, prevent downtime and to extend the life of your equipment. This machine is an electrical appliance. Care must be taken to reduce the risk of electrical shock.
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 Nautilus Extreme MXE-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.

CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the Nautilus Extreme MXE-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.

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. •...

LUBRICATE REGULATOR PISTON To maintain consistent adequate pressure delivery to the cleaning tool, the piston seal of the MXE-500 pressure regulator must be lubricated regularly. 1. Release pressure from system before proceeding. Brass Knob 2. Remove Brass Knob from the regulator body. 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.
