Operation Procedures
Knowledge of the proper operation of the M500H 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 Olympus M500H. Cord #1 powers Vacuum Motor #1, Vacuum
Motor #2 and the Solution Pump. (and Waste Pump if equipped with optional Auto Pump-out System.);
Cord #2 powers the Heater. The amperage required by each cord requires that the two cords be plugged into
separate 15amp or 20amp circuits. (With Auto Pump-out System Cord #1 requires a 20amp circuit.)
Plug the two power cords into two outlets from different circuits.
If you are not sure if you are connected to separate circuits, use a Breaker Buddy (item # AX49), available
from Hydro-Force, to test your circuits in the following manner:
•Plug the cords into the two outlets being tested, and then plug the Breaker Buddy into the two cords.
•If the green indicator light fails to light, you may be on the same circuit and must select a different
plug for one of the cords.
•If the green indicator light comes on, you are plugged into two different circuits; connect the cords to
the machine and proceed with your set-up procedure.
If a circuit breaker trips during operation, reset the breaker and move the cord to another outlet as needed.

2A. Water Supply & Chemical Mixing– Manual Fill:
•Pour up to 12 gallons of hot water into the solution tank at the front of the machine. The water
temperature in the solution tank cannot exceed 160°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.
2B. Water Supply & Chemical Dilution – Optional Auto-Fill System:
•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 10 for instructions.)
Chemical Feed Setup:
•Remove the chemical feed hose from the solution tank.
•Place the end of the 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 standard tip used with the M500H 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 back 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-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.

Water Supply:
•Once the correct metering tip is in place:
oConnect the Auto-Fill Water Supply Hose to the water inlet (the male quick-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 in the solution tank does not exceed 160°F.
•Faucet adapter kits (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.
•Snap the beaded chain off the connector on the valve.
oMove the bottle down to decrease the water level.
oMove the bottle up to increase the water level.
•Snap the chain back into the connector.
•Turn the water supply back on.
If the chemical is not drawing, or if the tank is not filling
or is overflowing, refer to the trouble shooting guide, or
contact your distributor for assistance.

3. Priming the High-Pressure Pump:
Once water is in the solution tank, the high-pressure solution pump must be primed:
•Connect the short prime hose to the solution outlet (female quick-connect on the front of the
machine.)
•Direct the end of the hose back into the solution tank and turn the solution pump switch to the ON
position.
•When a steady stream of water is flowing out of the hose, turn off the solution pump, remove the
hose, and proceed with the set-up procedures.
If the pump does not prime quickly, the vacuum may be used to aid priming:
•Direct the end of the short prime hose into the vacuum barb on the front of the machine.
•Turn on one or both of the vacuum motors
•Turn on the solution pump.
•Cup a hand around the hose & barb to increase the vacuum suction on the hose.
•When water is flowing out of the hose, direct the hose to the solution tank and turn off the vacuum
motors to ensure the flow continues when the vacuum is removed.
•When the flow is steady, turn off the solution pump, remove the hose, and proceed with machine set-
up procedures.
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 inline 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
5. Connection of Vacuum Hoses:
A 1-1/2” x 25’ Vacuum Hose is included with the M500H. The 2” cuff on the 25’ vacuum hose is connected
to the Vacuum Barb on the front of the machine. 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. While the M3-500 can be
operated with only one vacuum for cleaning delicate fabrics, in most situations you will turn both vacuum
switches ON.

6. Optional Auto Pump-out System - Connection of Pump-out Hose:
The pump-out hose is a 50’ section of 3/4” garden hose.
•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.
When ready to begin cleaning, turn the waste pump switch to the ON position.
•Do not turn on waste pump switch unless pump-out hose is connected and has been routed
to a proper drain.
6A. Waste Tank Shutoff:
If not equipped with an Auto Pump-out System or 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 ball 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.
oTurn off the pump switch while draining the tank.
oTurn 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.

7. Pressure Adjustment:
When the high-pressure solution pump is on and primed, pressure will show on the gauge.
•To decrease the pressure, turn the brass knob on the pressure regulator to the left (counter-
clockwise.)
•To increase the pressure, turn the brass knob on the pressure regulator to the right (clockwise.)
•To adjust pressure to your tool and surface requirements:
oCheck the pressure on the gauge and re-adjust as needed to set the machine at the desired
pressure.
oChoose the pressure setting that best meets your type of cleaning.
oSpray the wand and check the pressure drop. Adjust pressure, change jets or perform repairs
as needed to maintain proper pressure. Contact your distributor for advice or assistance.
To increase the solution pressure, turn the
regulator knob clockwise. To decrease the solution pressure, turn the regulator knob counter-clockwise.
The maximum pressure setting is 500psi; 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: 300psi
•Tile Cleaning with Gekko Tool AR54: 500psi
If adjusting or maintaining pressure becomes a
problem, refer to the trouble shooting guide or
contact your distributor for advice or assistance.

16
8. Heater:
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 hoses before turning heater ON.
Allow the heater to heat up for about 5 minutes before starting to spray tool.
While the heater allows for maximum operating temperature of approximately 190ºF, the temperature of the
cleaning water delivered to the tool is dependant 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 160°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.

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.
•If used disconnect the Hydro-Filter from the vacuum hoses and clean
the filter as needed. Replacement filter bags are available (AC11A.)
•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 auto-fill system was utilized, place the chemical feed
hose back into the solution tank.
•If the waste pump-out system was used:
oTurn the waste pump switch “on” to pump out any remaining water from the recovery tank.
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 tank and clean filter as needed.
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.
