Safety
This machine is an electrical appliance.
Care must be taken to reduce the risk of electrical shock.
READ AND UNDERSTAND ALL INSTRUCTIONS BEFORE OPERATIN THE MX3-200H.
•To reduce the ris 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 shoc . 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 s etch to the right. Ma e 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 lea ing, 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 brea er. 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 MX3-200H, 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.
oThe anti-freeze solution must be completely flushed from the machine before it is returned to service.
•The MX3-200H must not be used to pic 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 tan , 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 tan daily to eep pump-out filter and pump from becoming
clogged. Store the MX3-200H with the recovery tan lid open.
•Keep Vacuum Inlet Filter clean and chec 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
wor 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 tan s are full of water. Drain solution and recovery
tan s, 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
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 Gate eeper 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 Gate eeper 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.

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
brea er immediately, but it may not provide sufficient voltage for proper operation and the brea er 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 brea er trips or the pump circuit brea er trips during operation, reset the brea ers 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:
•Pour up to 12 gallons of hot water into the solution tan 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 tan .
The amount of chemical will vary depending on the type of chemical used, the amount of water in the
tan , and the material being cleaned; consult the chemical pac aging for specific mixture ratios.
•Powdered chemicals should be dissolved in water before adding to the water in the solution tan .
DO NOT RUN OUT OF WATER WHILE USIN 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.
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 tan . Ma e sure float is attached to valve and hanging
freely, above the bottom of the solution tan . 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.

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 bac on the barb
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-li e viscosity. Thic er (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.

Water Supply:
•Once the correct metering tip is in place:
oConnect the Auto-Fill Water Supply Hose to the water inlet (the male quic -connect on the front
of the machine.)
oConnect 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 its (Hydro-Force item #AX21 & AX22) are available that allow connection to different
types of faucets if needed.
To adjust the water level in the solution tank:
•Turn off the water supply.
•Adjust the length of the chain connecting the float bottle
to the float valve. Unhoo the float from the beaded chain
on the valve. Unsnap the hoo from the beaded chain on
the float.
Move the bottle down to decrease the water level.
Move the bottle up to increase the water level.
•Snap the bac onto the float chain & hoo the float bac
onto the valve chain.
•Turn the water supply bac on.

3. Priming the High-Pressure Pump:
Once water is in the solution tan , 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 quic 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 bloc off the vacuum
inlet with your hand. The vacuum will pull solution through the pump and priming hose into the
vacuum tan .
•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 tan , the pump should remain primed.
If the pump still does not prime, or if flow is low or unsteady, chec the hose from the solution tan to the
pump (as well as the filter) for clogging, in s, 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 quic connect on the front of the
machine). Connect the other end of the hose to the male quic 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 roc er switch on the Left is Heater Circuit #1, drawing power from Cord #1
•The roc er 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. Ta ing additional drying sto es without spraying water
between spraying stro es 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 1-
1/2” 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:
A ey problem with portable extractors is that they have small tan s 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 ma es a big mess, can decrease vacuum lift and damage the vacuum motors.
The Foam Downer ills 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 tan , brea ing down the foam before it can cause any damage or ma e 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 tan 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 brea
down the foam you can open the valve more or add more defoamer to the water to ma e a stronger solution.
With the valve open one half turn it will ta e 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 bac 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.
If not using the waste pump-out, the pump-out hose does not need to be connected. When the recovery tan
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 tan from overfilling and waste water from getting into the vacuums.
When this occurs:
•Immediately shut off the vacuum switches.
•Drain the recovery tan .
oTurn off the pump switch while draining the tan .
oTurn pump switch bac upon resumption of cleaning.
•Close the drain valve and turn the vacuum switches bac on when
ready to resume cleaning.
If the pump-out or vacuum shutoff is not wor ing properly, refer to the
trouble shooting guide or contact your distributor for advice or assistance.

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 tan , 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 tan , 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 quic -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 tan , use the vacuum hose and
vacuum the excess water from the tan .
•If the optional auto-fill system was utilized, place the chemical feed
hose bac into the solution tan .
•If the optional Auto waste pump-out system was used:
oTurn the waste pump switch “on” to pump out any
remaining water from the recovery tan .
oTurn switch off, remove the pump-out hose from the outlet
fitting and replace the cap.
oRoll up hose toward drain to remove remaining water from
hose.
oConnect 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 tan and clean vacuum shutoff filter as needed.
Clean Pump-Out filter screen. Replace shutoff assembly and tan lid.
•Drain any remaining water from the recovery tan and dispose in sanitary drain. Do not use the same
