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 MX500E. • To reduce the risk of property damage or injury, repairs to electrical systems should only be performed by experienced technicians.

• Solvent-based or water-based solutions containing solvents may damage the pump, hoses, and other components. Do not assume chemical compatibility. Contact your distributor or Hydro-Force if you have questions regarding the compatibility of your chemicals with the machine.
Section Vacuum Connections The MX500E 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 BE PERFORMED BY A QUALIFIED TECHNICIAN While there is debate on which vacuum alignment provides the best extraction, this much is true:...

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. •...

Dilution 85 - 1 Chemical Feed Hose Metering Tip Kit (Hydro-Force Item# PDE001) contains 14 different colored metering tips, allowing dilution rates from 11:1 up to 427:1. Refer to the chart below to select the tip that meets the dilution rate for your chemical application.
Connect the other end of the hose to a water faucet, and then turn on the water. • Hot water can be used as long as the temperature does not exceed 130°F or 54°C. • Faucet adapter kits (Hydro-Force item #AX21 & AX22) are available that allow connection to different types of faucets if needed.

5. Connection of Vacuum Hoses: The vacuum connection port on the machine can be either a 2” hose barb or 2” male Flash Cuff. Both are included with your MX500E. The desired connector can be threaded into the vacuum port on the front of the machine. A 2”...
6. Optional Foam Downer: A key problem with portable extractors is that they have small tanks where foam dissipates slowly. If you have had issues with foam or are anticipating foaming problems, you will want to use a Foam Downer. Foam can be drawn into the vacuums before the vacuum shutoff closes.
Page 16
7. 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.) •...
8. 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.
Accessory Storage Options: The MX500E 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 MX500E is sized and recessed to hold a five gallon bucket or two one-gallon chemical bottles as well as two 2QT sprayers.

NAUTILUS MX500E SWITCH PANEL: (Shown with optional Pump-Out switch) Solution Pump Switch When the switch is turned to the ON position power is supplied to the solution pump motor. When not using solution (Extracting Only) do not turn this switch ON.
Section Maintenance Proper maintenance is required to keep the MX500E 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. Disconnect electrical power before performing any service or maintenance inside machine base or before testing or repairing switches or power cords.

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 28
CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the MX500E, 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 SEAL To maintain consistent adequate pressure delivery to the cleaning tool, the piston seal of the MX500E 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 33
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 34
Storage Prep and Freeze Protection Procedures: Your Nautilus MX500E 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 MX500E is transported or stored in freezing temperatures, the following procedures should be performed.
