Years of experience, engineering, and planning have gone into the design and manufacturing of the Nautilus. We take a great deal of pride in the Nautilus; our goal is no less than your complete satisfaction.

(see Page 9 for details.) • Do not use the Nautilus outdoors, in standing water or on wet surfaces. Do not store the Nautilus in wet conditions. If extractor is leaking, unplug machine power cords from outlets before approaching or touching machine.
Page 11
Store, transport, and use this equipment only in temperatures well above freezing. (32ºF or 0ºC). If you suspect the Nautilus has been frozen, do not plug in or turn on machine until you are sure it has thawed completely.
Section Vacuum Connections The Nautilus 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 25’ power cords are supplied with the Nautilus. The amperage required by each cord requires that the two cords be plugged into separate circuits. See tables in Technical specifications and wiring diagrams for your particular model to determine the circuit breaker needs for each cord.

16-1/4oz of chemical to each gallon of water.) • The recommended tip for use with the Nautilus 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 15
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...
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 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. •...

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. The other end with the 1- 1/2” cuff is connected to the cleaning tool. When ready to begin cleaning, turn both vacuum switches to the ON position.
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.

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.) •...
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.
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.
Bucket & Sprayer Storage The top of the Nautilus is sized and recessed to hold a five gallon bucket or two one-gallon chemical bottles as well as two 2QT sprayers. Power Cord Storage The back of the Nautilus has two sets of cord wraps to hold two 12/3 x 25’...

NAUTILUS SWITCH PANEL: (Shown with optional Pump-Out Switch) Heater – Power from Cord #2. When the switch is turned to the ON position power is supplied to the 1750W heating element, if so equipped. Vacuum #1 – Power from Cord #1.
Section Maintenance Proper maintenance is required to keep the Nautilus 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.

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 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 63
CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the Nautilus, 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 64
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. •...

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.) •...

LUBRICATE REGULATOR PISTON SEAL To maintain consistent adequate pressure delivery to the cleaning tool, the piston seal of the Nautilus pressure regulator must be lubricated regularly. 1. Release pressure from system before proceeding. Brass Knob 2. Remove Brass Knob from the regulator body.
Page 68
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.

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 Nautilus. Direct tool spray back into the solution tank or into a bucket. Repeat for all tools to be protected.
