OUTLET

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 MX3-1200E.

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

experienced technicians. Contact your distributor for assistance. Unplug machine power cord from outlet before performing any repairs on the extractor.

• This machine shall be grounded while in use to protect the operator from electric shock. The machine is

provided with a three-conductor cord and a three-contact grounding type attachment plug to fit the proper grounding type receptacle. The green and yellow conductor in the cord is the grounding wire. Never connect this wire to other than the grounding pin of the attachment plug.

• This machine is for use on a nominal 240-volt circuit and

has a grounding plug that resembles the plug illustrated in the sketch to the right. Make sure that the machine is connected to an outlet having the same configuration as the plug. No plug adapter should be used with this machine.

• The power cords supplied with this machine are properly

sized to handle the electrical load of this machine and properly grounded as described above. Any extension cords used with this machine must be similarly sized with an equal or greater load rating and grounded to assure safe operation.

• The two power cords must be plugged into separate circuits during operation.

• Do not use the MX3-1200E outdoors, in standing water or on wet surfaces. Do not store the MX3-1200E in

wet conditions. If extractor is leaking, unplug machine power cords from outlets before approaching or touching machine.

• Do not unplug power cord by pulling on the cord. Grasp the plug end when unplugging the cord. Do not pull

the extractor by the cord. If cord or plug is damaged, do not use cord. Replace with new cord or repair as needed before use.

• Overloaded circuit may not always trip circuit breaker. Reduced voltage to a machine on an overloaded circuit

will prevent components from operating properly.

This machine must be protected from conditions which

may damage the pump, tank, hoses and other components.

• Freezing of water in this machine will cause serious damage. The MX3-1200E, solution hoses, and tools

must be protected from freezing temperature. Store, transport, and use this equipment only in temperatures well above freezing. (32ºF or 0ºC). If you suspect the MX3-1200E has been frozen, do not plug in or turn on machine until you are sure it has thawed completely.

• If the equipment cannot be stored or transported in a warm environment, it can be guarded from freezing by

running an anti-freeze solution through the incoming water lines, chemical feed system, solution pump, solution lines, tools and pump-out pump. The machine is filled at the factory with anti-freeze to eliminate damage during shipment in cold weather.

o The anti-freeze solution must be completely flushed from the machine before it is returned to service.

• The MX3-1200E must not be used to pick up flammable or combustible materials or used in areas where these

materials may be present.

• 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.

• Do not clean with solutions that are at temperatures above 140ºF or 60ºC.

• Rinse the solution tank, chemical system, and pump with fresh water after each day’s use.

• Do not allow pump to run dry. Always maintain adequate solution level to supply solution pump.

• HP hoses may rupture if worn or damaged. Do not use HP solution hoses if hose covering is cut, bulging, or

otherwise damaged. Examine HP solution hoses daily and replace or repair hoses as needed.

• Use a Hydro-Filter II and clean the recovery tank daily to keep pump-out filter and pump from becoming

clogged. Store the MX3-1200E with the recovery tank lid open.

• Keep Vacuum Inlet Filter clean and check float for proper operation. Do not operate the MX3-1200E without

the Vacuum Inlet Filter in place. Use defoamer to eliminate foam build-up during cleaning and prevent

foam/moisture from entering vacuums.

Use common sense to protect yourself and others while using this equipment.

• Keep pets and children away from the machine when in use.

• Keep all body parts, hair, and loose clothing away from openings and moving parts. Always wear appropriate

work clothing and safety equipment when operating unit.

• Use extra care when cleaning on stairs. Wet carpet on stairs can be slippery.

• Do not move the MX3-1200E up or down stairs when tanks are full of water. Drain solution and recovery

tanks, and secure base latches before moving unit up or down stairs. Lift using only the machine handles designed & designated for moving and lifting.

• Water may be spilled, drip, or be exhausted from vacuums during operation. Place unit in area where water will

not cause damage or use drop cloth to protect surfaces.

Vacuum Connections

Section

The MX3-1200E 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:

• Two vacuums in series: The vacuum lift is increased by 1.6 times

the rating of a single vacuum, while the air flow stays the same as a single vacuum.

• Two vacuums in parallel: The vacuum air flow is increased by 2.0

times the rating of a single vacuum, while the lift says the same.

Air flow is usually measured in cubic feet per minute, indicated as CFM. Lift is usually measured in inches of water column, indicated as “H2O or “WC.

To connect vacuums in parallel:

1. Connect the discharge / exhaust hose from vacuum #1 to the exhaust

pipe on machine base.

2. Place the rubber stopper into the vacuum inlet port of vacuum

manifold number two.

3. Open vacuum gate valve and attach the Gatekeeper to prevent

accidental valve closure. When connected in parallel, both vacuums must be running during cleaning. Vacuums cannot be operated individually.

To connect vacuums in series:

1. Connect the discharge / exhaust hose from vacuum #1 to the vacuum

inlet port of vacuum manifold number two.

2. Place rubber stopper into the exhaust pipe on machine base.

3. Remove Gatekeeper and close vacuum gate valve.

When connected in series vacuums can be operated individually if desired during cleaning.

Always secure the Gate Valve Open with the Gatekeeper when connecting the vacuums in Parallel. Closing the Vacuum Gate Valve with the hoses connected in the

Parallel configuration may cause damage to Vacuum

#2.

GATEKEEPER

Operation Procedures

Knowledge of the proper operation of the MX3-1200E is required to ensure user safety and efficient performance of the extractor.

SET UP AND OPERATION

1. Electrical Cords:

Two 15m extension cords are supplied with the Nautilus MX3-1200E. 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 separate circuits:

• Cord #1 (Left side) will supply power to both vacuums.

• Cord #2 (Right side) will supply power to the Solution Pump and Pump-out Pump.

The machine must be connected to separate 220/230/240volt 10amp circuits. An overloaded circuit will not always trip the circuit breaker immediately, but may not provide sufficient voltage for proper operation and the breaker may trip eventually.

Plug the two power cords into two outlets from different circuits. Proceed with your set-up procedure. If a circuit breaker trips or the pump circuit breaker trips during operation, reset the breakers and move the cord to another outlet as needed.

2A. Water Supply & Chemical Mixing– Manual Fill:

Proportioning Valve

Chemical Feed Hose

• 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 140°°°°F or 60°C.

• 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; consult the chemical packaging for specific mixture ratios.

• Powdered chemicals should be dissolved in water before adding to the water in the solution tank.

DO NOT RUN OUT OF WATER WHILE USING THE MACHINE! Ensure that the tank contains enough water to complete each job. If the water level is low: stop cleaning, turn off the pump, and refill the tank. Running the pump dry will damage the pump and void the warranty.

Pour appropriate amount of hot water into

Add appropriate amount of chemical to water

2B. Water Supply & Chemical Dilution – Auto-Fill:

• The chemical dilution rate is controlled by the metering tip, and the dilution rate can only be changed by

changing the metering tip (See “How to Change the Metering Tip” on Page 11 for instructions.)

Chemical Feed Setup:

• Remove the chemical feed hose from the solution tank. Make sure float is attached to valve and hanging

freely, above the bottom of the solution tank. Adjust float height to maintain adequate water level.

• Place the end of the chemical feed hose into a container of liquid chemical.

• If the tip is removed, and the proportioning system operated with no tip, the dilution rate will be 8:1, the

equivalent to adding 16-1/4oz of chemical to each gallon of water. (125ml per liter)

• The standard tip for use with the MX3-1200E 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. (3.91ml per liter)

• If a fresh water rinse with no chemical is desired, simply leave the chemical feed hose inside the

solution tank.

• 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

Turquoise Tip Dilution 256 - 1

Red Tip Dilution 85 - 1

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.

• For example: if you require 1-1/2 ounces of chemical per gallon of water, change to the red metering tip

with the dilution rate of 85:1. (11.77ml of chemical per liter of water)

• The dilution rates are based on chemicals with water-like viscosity. Thicker (more viscous) chemicals will

dilute at a different rate.

• For powdered chemicals, a liquid concentrate must be made. Mix the concentrate according to the

manufacturer’s directions, and then select the appropriate metering tip.

• Contact your distributor or Hydro-Force if you have questions about your chemical.

4. Priming the High-Pressure Pump:

Before priming the pump, make sure your solution hose and tool are connected to the machine.

Once water is in the solution tank, the high pressure pump must be primed:

• There is a prime valve located on the lower back portion of the machine.

• Turn on both vacuums and the solution pump. Press the priming lever for a few seconds while you

block off the vacuum inlet with your hand. The vacuum will pull solution through the pump and prime valve into the vacuum tank.

• Let off the prime valve and your pump is primed. As long as there is solution in the tank the pump

should remain primed. You can now proceed with cleaning or turn the pump off and continue your set-up.

If the pump still does not prime, or if flow is low or unsteady, check the hose from the solution tank to the pump (as well as the filter) for clogging, kinks, or restrictions. Clean or replace hose and/or filter and repeat the priming procedure.

If you are having trouble with the pump, refer to the trouble shooting guide or contact your distributor for advice or assistance.

5. Connection of Vacuum Hoses:

The vacuum connection on the machine can be either a 2” hose barb or 2” male Flash Cuff. Both are included with your MX3-1200E. The desired connector can be threaded into the vacuum port on the front of the machine. A 2” female Flash Cuff 1-1/2” hose adapter is also included to connect the 1-1/2” vacuum hose to the 2” male Flash Cuff on the machine. A 2” hose cuff for 1-1/2” vacuum hose is included to connect the 1-1/2” vacuum hose to the 2” hose barb on the machine.

There are three components used to connect the cleaning tool to the vacuums and recovery tank:

1. A short 4’ vacuum hose: Connect one end to the 2” vacuum barb or 2” male Flash Cuff to the front

of the machine using the appropriate cuff and the other to the outlet side of the Hydro Filter.

2. A Hydro Filter II inline filter.

3. A 25’ Vacuum Hose: The 2” cuff on the 25’ vacuum hose is connected to the inlet side of the hydro

filter. 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. If connected in series, the MX3-1200E can be operated with only one vacuum for cleaning delicate fabrics. (See Vacuum Connection instructions on Page 8) In most situations you will turn both vacuum switches ON.

Foam Downer – Optional Accessory:

FOAM

FOAM DOWNER cannot be used

HOSE HOOK

AH95

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. Foam and water blowing out the vacuum makes a big mess, can decrease vacuum lift and damage the vacuum motors.

The Foam Downer kills foam as waste water enters the machine. Place a container of liquid defoamer on the top of your MX3-1200E. 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.

• Mounts and is ready to use in seconds

• Uses defoamer very economically

• NO LABOR is involved to spray or spread defoamer – it’s all automatic

• Keeps silicone defoamers off the floor where they can cause resoiling problems

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) or 31.35ml per liter. Place the draw tube into the gallon of diluted defoamer and open the needle valve one half turn as your starting point. If this is not sufficient to break down the foam you can open the valve more or add more defoamer to the water to make a stronger solution. With the valve open one half turn it will take approximately one half hour to drain the gallon of diluted defoaming solution.

6. Connection of Pump-out Hose:

Pump

out Filter

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.

• Place the other end of the hose in a commode or drain connected to the sanitary sewer system.

• Secure hose end to prevent movement during pumping.

 Use defoamer to prevent foam build-up in recovery tank during cleaning and to keep

foam/moisture from entering vacuums.

 Use Hydro Filter II inline filter to trap and remove debris from the waste water before it

enters the recovery tank. Excess debris in recovery tank may clog Pump-Out filter. Clean Filter as needed during use.

 Do not turn the Waste Pump switch ON unless pump-out hose is connected and has been

routed to a proper drain.

 The Waste Pump does not use a float switch and will run as soon as the Waste Pump switch

is turned ON. It is made to run continuously while cleaning, as this type diaphragm pump can run dry without damage.

When ready to begin cleaning, turn the Waste Pump switch to the ON position.

Connect the Female Garden Hose Fitting end of the Pump-out Hose to the outlet fitting on the back of the recovery tank. Place the other end of the pump-out hose in a sanitary drain.

If not using the waste pump-out, the pump-out hose does not need to be connected. When the recovery tank fills during cleaning, the float assembly in the vacuum inlet filter will rise and will automatically shut off the vacuum air flow to prevent the recovery tank from overfilling and waste water from getting into the vacuums. When this occurs:

• Immediately shut off the vacuum switches.

• Drain the recovery tank.

o Turn off the pump switch while draining the tank. o Turn pump switch back upon resumption of cleaning.

• Close the drain valve and turn the vacuum switches back on when

ready to resume cleaning.

If the pump-out or vacuum shutoff is not working properly, refer to the trouble shooting guide or contact your distributor for advice or assistance.

Draining the Recovery Tank

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. When the tool is sprayed the gauge will display the pressure being delivered to the tool. When the tool is not being sprayed the gauge will return to zero.

• To decrease the pressure, turn the black knob on the pressure regulator/unloader to the left (counter-

clockwise.)

• To increase the pressure, turn the black knob on the pressure regulator/unloader to the right

(clockwise.)

• To adjust pressure to your tool and surface requirements:

o Spray the tool. o Check the pressure on the gauge. o Re-adjust as needed to set the machine at the desired pressure. o Choose the pressure setting that best meets your type of cleaning.

To increase the solution pressure, turn the regulator/unloader knob clockwise.

The maximum pressure setting is 1200psi; however, the highest pressure attained is dependent on the amount of water flow at the tool:

• Smaller jets and lower flow will allow for

higher pressure at the tool.

• Larger jets and higher flow will lower the

maximum pressure attained at the tool.

The desired setting will depend on the type of cleaning and tool used. For example:

• Carpet Cleaning with 2-jet AW29 wand: 400psi

• Tile Cleaning with SX-15: 1000psi

If adjusting or maintaining pressure becomes a problem, refer to the trouble shooting guide or contact your distributor for advice or assistance.

To decrease the solution pressure, turn the regulator/unloader knob counter-clockwise.

Pressure gauge & Regulator/Unloader

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.

• When finished cleaning, turn off all switches.

• If the auto-fill system was used and there is still water in the solution tank, push the float down to release

the water inlet hose pressure before disconnecting the hose from the faucet. Disconnect the water inlet hose from the quick-connect on the front of the machine.

• Disconnect the solution hose and vacuum hose from the cleaning tool. Pull valve trigger to release

pressure from the hose before disconnecting solution hose from cleaning tool.

• Disconnect the Hydro-Filter II from the vacuum hoses and clean the

filter as needed. Replacement filter screens are available (AC10C.)

• Disconnect the vacuum hose and solution hose from the machine.

• If water remains in the solution tank, use the short

vacuum hose and vacuum the excess water from the tank.

• If the auto-fill system was utilized, place the chemical feed

hose back into the solution tank.

• If the waste pump-out system was used:

o Turn the waste pump switch “on” to pump out any remaining water from the recovery tank. o Turn switch off, remove the pump-out hose from the outlet fitting and replace the cap. o Roll up hose toward drain to remove remaining water from hose. o Connect ends of hose together to prevent dirty water from dripping from hose during transport.

• Disconnect the power cords from the outlets and from the machine.

• Remove the float shutoff assembly from

the recovery tank and clean vacuum shutoff filter as needed. Clean Pump-Out filter screen. Replace shutoff assembly and tank lid.

• Drain any remaining water from the recovery tank

and dispose in sanitary drain. Do not use the same bucket to drain the tank that you use to fill the tank.

• Roll up all hoses and cords.

Collect and store extractor, all tools, and accessories.
