Safety

Section

Care must be taken to reduce the risk of electrical shock.

READ AND UNDERSTAND ALL INSTRUCTIONS BEFORE OPERATING THE MX3-200H.

• 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 (or 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 120-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. A properly sized or rated GFCI protected cord can be used for additional protection.

• The two power cords must be plugged into separate circuits during operation. The Dual Circuit Indicator will

ensure that the two cords are operating on different circuits (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.

• 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 is an electrical appliance.

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 MX3-200H, 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 MX3-200H 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 MX3-200H 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 130ºF.

• 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 MX3-200H with the recovery tank lid open.

• Keep Vacuum Inlet Filter clean and check float for proper operation. Do not operate the MX3-200H 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 MX3-200H 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 MX3-200H 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:

• 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 MX3-200H is required to ensure user safety and efficient performance of the extractor.

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. The amperage required by each cord requires that the two cords be plugged into separate circuits: Use of the MX3-200H with the heater will require operation on two 20amp circuits. 20amp circuits are usually found in kitchens and bathrooms. Operation without the heater will allow both cords to be connected to separate 15amp circuits. An overloaded circuit will not always trip the circuit breaker immediately, but it 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. If the Dual Circuit Indicator green light fails to light, you may be on the same circuit and may need to select a different plug for one of the cords. If the Dual Circuit Indicator green light comes on, you are plugged into two different circuits. Proceed with your set-up procedure.

(Dual Circuit Indicator light may take up to 30 seconds to recognize the two circuits and turn ON.)

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.

When operating the MX3-200H, DO NOT turn the heater on until after the pump has been primed and the solution hose and tool have been connected.

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

Proportioning Valve

Chemical Feed Hose

• Pour up to 12 gallons of hot water into the solution tank at the front of the machine. The water

temperature cannot exceed 130°°°°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; 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. Optional Auto-Fill System - Water Supply & Chemical Dilution:

• 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.)

• 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.

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

solution tank.

CHEMICAL DILUTION RATES

Proportioning Valv

• 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.

• 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.

3. Priming the High-Pressure Pump:

PUMP PRIMING HOSE

NM5080

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.

• Turn on both vacuums and the solution pump. Insert the end of the priming hose into the vacuum

inlet port on the front of the machine and cup your hand around the hose to block off the vacuum inlet with your hand. The vacuum will pull solution through the pump and priming hose into the vacuum tank.

• Turn off the pump and vacuums. Disconnect the priming hose. You can now continue your set-up.

As long as there is solution in the tank, the pump should remain primed.

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.

4. 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. The pressure is preset, there is no pressure adjustment to be made.

Connect the male end of the HP Solution Hose Assembly to the female solution outlet fitting on the machine. Connect the female end to the cleaning tool.

5. 2000W Heater Operation:

To prevent damage to the heater, the heater must have water in it before it is turned ON. Fill solution tank, prime the pump and connect solution hose and tool before turning heater ON.

The 2000W heater has two circuits. For maximum heat both circuits must be on. In situations where there is only one available 20amp circuit, the heater can be operated using only one 1000W circuit so that the second cord can safely be used on a 15amp circuit.

• The rocker switch on the Left is Heater Circuit #1, drawing power from Cord #1

• The rocker switch on the Right is Heater Circuit #2, drawing power from Cord #2

While the heater allows for maximum operating temperature of approximately 190ºF, the temperature of the cleaning water delivered to the tool is dependent on two factors:

• The starting temperature of the water: Starting with hotter water will require a smaller temperature

increase from the heater to reach the maximum temperature.

The water temperature in the solution tank cannot exceed 130°°°°F.

• Flow rate: The lower the flow rate of the water through the heater, the more time the water will be inside

the heater. The water will have more time to be heated and can reach a higher temperature. High water usage and flow rate will not allow the water enough time to be heated and the temperature of the water delivered to the tool will be much lower. The flow rate can be lowered by putting smaller jets in the cleaning tool and by reducing the amount of time the wand is sprayed. Taking additional drying stokes without spraying water between spraying strokes will help increase the potential temperature rise.

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 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 11/2” vacuum hose to the 2” hose barb on 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 MX3-200H. 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 MX3-200H 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.

7. Optional Foam Downer:

FOAM

FOAM DOWNER cannot be used with

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 use a 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 MX3-200H. 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.

• 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). 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.

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.)

• 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.

Pump-out Filter

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.

Float Shutoff Assembly

Draining the Recovery Tank

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.

• If using the 2000W heater, turn the heater off before finishing each job. This will allow the water to cool

the heater as you finish the job.

• When finished cleaning, turn off all switches.

• If the optional 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.

• If a Hydro Filter II inline filter was used, 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 vacuum hose and

vacuum the excess water from the tank.

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

hose back into the solution tank.

• If the optional Auto 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.

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.

To test the Foot Valve:

• Remove the Filter & Foot Valve from the end of the chemical feed hose and rinse in fresh water.

• Blow through the valve from the filter side of the barb.

o If the Foot Valve is functioning, air should move freely from the filter side, but will not flow from

the barb side of the filter.

o If valve is not functional, clean or replace as needed.

Heavy chemical build-up can be removed with a mild acid rinse and/or the use of a brush and compressed air.

CLEAN VACUUM SHUTOFF ASSEMBLY SCREEN:

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. If debris builds up on this filter, it will reduce the vacuum air flow and may cause a significant decrease in the rate of water recovery. If debris prevents the float from moving or seating against the Filter Cap Assembly, it may not stop the airflow when the tank fill with water, and the water will be sucked into the vacuums and blown out the exhaust.

Use defoamer to prevent foam or moisture from entering vacuums (See Page 15).

To clean:

• Do not pull up on top of cap. Carefully pull up from the bottom of filter cap assembly to pull the

assembly off of the stand pipe. Then pull float off of riser pipe.

• Pull fibers and lint off and rinse filter cap assembly and float with clean water.

• Place the float back on the riser pipe then push the filter cap assembly back onto the stand pipe and

replace the recovery tank lid.

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. This debris can clog the Waste Pump and the Vacuum Shutoff Assembly. The Hydro-Filter II must be examined and cleaned regularly to keep the MX3-

200H functioning properly:

• Grasp and turn the lid counterclockwise to open the Hydro-Filter II lid.

• Remove the filter screen. Examine the screen and clean or replace as needed.

• Rinse the body of the Hydro-Filter II with clean water.

• Examine the o-ring lid seal and replace as needed.

Drain water from Recovery

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.

Unplug both power cords and drain the recovery tank before attempting to service

the drain valve.

• Unscrew the nuts and remove the four bolts holding the valve assembly to the flange attached to the

recovery tank. Unless the flange is damaged, it does not have to be removed from the tank, even when replacing the drain valve.

• Separate the valve body, outlet adapter and gaskets from the flange.

Remove four bolts holding valve assembly to flange fitting

Unless damaged or leaking between tank and flange, the flange fitting does not have to be removed

VALVE BODY

DRAIN VALVE – PEA11

GASKET – NM3019

• Examine the valve body for wear. Check the valve slide

for deep scratches. Deep scratches will allow water to flow past gaskets and leak from valve. Replace valve if needed.

• Examine the gaskets and replace if cut, torn or deformed.

• Raised, rounded side of gasket goes toward valve slide.

Larger flat sides seat on ring on flange and outlet adapter. Sand and debris will collect in the bottom of the valve body and prevent the slide from going down and seating properly.

• Clean debris out as needed so slide can move to bottom.

• Rinse valve body and reassemble valve body, gaskets and

outlet adapter, and place assembly back onto flange fitting.

• Replace four bolts and tighten evenly to secure assembly

to flange. Do not over-tighten bolts.

Clean debris from slot in bottom of valve body.

Storage Prep and Freeze Protection Procedures:

Your Nautilus MX3-200H 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 MX3-200H is transported or stored in freezing temperatures, the following procedures should be performed. ALSO, if the MX3-200H is stored for an extended period of time, the following procedure should be performed to prevent the pump seals from drying out.

1. In a separate container mix 1/2 gallon of water with 1/2 gallon of automotive radiator Ethylene Glycol

anti-freeze. (Propylene glycol can be used as a non-toxic alternative anti-freeze.). Mix well and pour into the solution tank.

2. Connect the solution hose to the solution outlet (female quick connect).

3. If not equipped with the optional Auto Fill System, snap an open quick connect onto the other end

of the hose and place the hose end back into the solution tank. If equipped with the Auto Fill system, connect the opposite end of the HP solution hose to the AutoFill inlet (male quick connect.) Leave the chemical feed hose in the solution tank and ensure the check valve filter is submerged in the anti-freeze solution. To speed the process the metering tip can be removed.

4. Turn the solution pump switch to the ON position and perform the pump priming procedure. When the

pump is primed, allow the anti-freeze to circulate for 5-10 minutes. Mix and add more anti-freeze solution as needed. For machines with the optional Auto Fill System, make sure end of chemical feed hose stays submerged in the anti-freeze solution. 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.

6. Turn the solution pump switch to the OFF position.

7. Use the vacuum hose to vacuum the remaining anti-freeze solution out of the solution tank and bucket.

8. If so equipped, remove the cap from the waste-pump out outlet fitting on the back of the machine.

Connect a hose to a drain or hold a bucket up to the fitting to catch the pump-out flow. Remove the lid from the recovery tank. Turn the Waste Pump switch to the ON position to engage the pump-out. Turn off the Waste Pump Switch as soon as you see anti-freeze flowing from the outlet fitting or hose.

9. Drain the remaining anti-freeze solution from the recovery tank and the machine is ready for storage.

RETURNING THE MX3-200H TO SERVICE AFTER STORAGE OR FREEZE PROTECTION:

To return the MX3-200H to service, the anti-freeze must be flushed from the machine. Flush the anti-freeze out of the machine by repeating the procedures above using fresh water in place of anti-freeze.
