The Hydro-Force Nautilus MX1200 is intended for commercial use only. This manual will provide users with the knowledge required to operate the Nautilus MX1200 safely, to understand how to properly operate and maintain the machine, and to ensure that the equipment operates at its maximum performance level.
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 MX1200. • 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 MX1200 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: •...
SET UP AND OPERATION 1. Electrical Cords: Two 50’ power cords are supplied with the Nautilus MX1200. Cord #1 powers both vacuum motors and the cooling fan; Cord #2 powers the high pressure solution pump and the waste pump. The amperage required by each cord requires that the two cords be plugged into two separate 20amp circuits: •...
2A. Water Supply & Chemical Mixing– Manual Fill: • Pour up to 12 gallons of hot water into the solution tank at the front of the machine. The water temperature cannot exceed 140° ° ° ° F. • Measure and add the appropriate amount of the desired liquid chemical to the water in the solution tank. The amount of chemical will vary depending on the type of chemical used, the amount of water in the tank, and the material being cleaned;...

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 140°F. • Faucet adapter kits (Hydro-Force item #AX21 & AX22) are available that allow connection to different types of faucets if needed.
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 –...
TO PRIME THE SOLUTION PUMP: 1. TURN ON BOTH VACUUMS 2. TURN ON THE SOLUTION PUMP 3. BLOCK OFF THE VACUUM PORT 4. PRESS THE PUMP PRIMING VALVE BLOCKING THE VACUUM PORT TO PRIME THE PUMP 5. Connection of Vacuum Hoses: The vacuum connection on the machine can be either a 2”...
Foam Downer – Optional Accessory: 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 setup your Foam Downer. Foam can be drawn into the vacuums before the vacuum shutoff closes.
6. 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/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.
Shutdown Procedures: • If using the 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 MX1200 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 MX1200 is sized and recessed to hold a five gallon bucket or two one-gallon chemical bottles as well as two 2QT sprayers.

Section Maintenance Proper maintenance is required to keep the MX1200 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: 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. To test the Foot Valve: •...
Page 29
CLEAN THE HYDRO-FILTER II: Build-up of debris in the filter screen of the 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: Build-up of fine silt inside the 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. • After cleaning out the recovery tank, remove the cap and connect the Pump-Out hose to the Waste Pump outlet fitting on the back of the machine;...

FLUSH SOLUTION TANK AND PUMP: (continued from previous page) • Disconnect the solution hose and tool. • Use the 4’ short section of vacuum hose to vacuum the remaining acid solution out of the solution tank. • Pour two or three gallons of clean water into the solution tank. •...
Page 32
FLUSH CHEMICAL SYSTEM: Chemical build-up in the 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.) • Remove the chemical feed hose from the solution tank and place the end of the hose in a bucket of fresh water or mild acid solution.
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 MX1200 pressure 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.
Storage Prep and Freeze Protection Procedures: Your Nautilus MX1200 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 MX1200 is transported or stored in freezing temperatures, the following procedures should be performed.
