Years of experience, engineering, and planning have gone into the design and manufacturing of the MX3-200H. We take a great deal of pride in the MX3-200H; our goal is no less than your complete satisfaction.

(see Page 9 for details.) • Do not use the MX3-200H outdoors, in standing water or on wet surfaces. Do not store the MX3-200H in wet conditions. If extractor is leaking, unplug machine power cords from outlets before approaching or touching machine.
Page 7
Store, transport, and use this equipment only in temperatures well above freezing. (32ºF or 0ºC). If you suspect the MX3-200H has been frozen, do not plug in or turn on machine until you are sure it has thawed completely.
Section Vacuum Connections The MX3-200H 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 MX3-200H. Cord #1 powers vacuum #1, the Solution Pump, Heater Circuit #1 and the cooling fan; Cord #2 powers vacuum #2, Heater Circuit #2 and the waste pump if so equipped.

16-1/4oz of chemical to each gallon of water.) • The recommended tip for use with the MX3-200H 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...
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. •...

6. 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 MX3-200H. The desired connector can be threaded into the vacuum port on the Vacuum Hose Connection with standard barb &...
The Foam Downer kills foam as waste water enters the machine. Place a container of liquid defoamer on the top of your MX3-200H. The vacuum air flow siphons the liquid defoamer through Foam Downer into the vacuum tank, breaking down the foam before it can cause any damage or make a mess.
8. Connection of Optional Pump-Out Hose: If your machine has the Optional Auto Pump-Out System you will have to connect the Pump-Out Hose to operate the Auto Pump Out. The pump-out hose is a 50’ section of 3/4” garden hose. (Use of smaller diameter hose may reduce flow.) •...
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 MX3-200H 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 MX3-200H 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 MX3-200H 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 28
CLEAN THE HYDRO-FILTER II: (If so equipped) When used with the MX3-200H, 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 29
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. •...

A restricted Pump Inlet Filter can prevent the solution pump from providing adequate pressure for cleaning. A restriction or air leak on the pump inlet hose can also damage the solution pump check valves and Inside View: MX3-200H Solution Tank plunger seals. • To examine the filter, open the solution tank lid on the front of the machine.
Page 31
FLUSH 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.) •...
Page 32
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 33
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 MX3-200H. Direct tool spray back into the solution tank or into a bucket. Repeat for all tools to be protected.
