120VAC GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should electrically malfunction, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and
grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
DANGER!
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with
a qualied electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do
not modify the plug provided with the appliance. If it will not t the outlet, have a proper outlet installed by a
qualied electrician.
This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in Figure 1
below. A temporary adapter illustrated in Figures 2 and 3 may be used to connect this plug to a 2-pole receptacle as shown in
Figure 2 if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded
outlet (Figure 1) can be installed by a qualied electrician. The green-colored rigid ear, tab, or the like extending from the adapter
must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must
be held in place by a metal screw. Grounding adapters are not approved for use in Canada.
Replace the plug if the grounding pin is damaged or broken.
The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to the
grounding pin only.
Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs and outlets. DO NOT
use extension cords more than 50 feet (15 m) long.

RX-20 / CMX-20 Owner’s Manual - 8PEX 500 - SP Owner’s Manual - 8
WARNING!
• If an extension cord is used, the plug and socket must be of watertight construction.
• Inadequate extension cords can be dangerous.
• Extension cords must be 12/3 and no longer than 50 feet. Replace the cord or unplug immediately if the
ground prong becomes damaged.
PLEASE NOTE: FOR NORTH AMERICA ONLY
Grounding adapters are not approved for use in Canada.

PREPARING THE MACHINE FOR USE
See the diagrams in the “Know Your Machine” section.
1Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2 Screw the Recovery Tank Lid (11) closed. Ensure the drain cap is closed tightly.
3 Pre-spray spots and heavy trafc areas before extracting with the detergent of your choice. Mix the pre-spray according to
the detergent manufacturer’s directions.
4 Fill the solution tank with clear water (12 gal. / 45.5 L capacity). If desired, add a detergent or rinse of your choice (we
recommend a CRI approved detergent). If you choose to add a detergent to the solution tank, be sure to mix well, and
always follow the use & dilution instructions on the detergent label. Only use a detergent with a pH between 5 and
10. Although this machine is designed to supply instant hot water, the addition of warm water to the solution tank would
increase heater efciency. Never use water above 130º F/54º C in the solution tank.
CAUTION!
Use low-sudsing, liquid detergents designed for carpet extraction.
OPERATING THE MACHINE
See the diagrams on page A-14.
1 Follow the instructions in the Preparing the Machine for Use section of this manual.
2Turn off all the switches. Plug the power cords into properly grounded outlets. Do not connect both cords to the same
outlet; the green, Circuit Indicator Light (D) on the switch plate should light up. If the indicator light does not come on, try
different outlets until it does. “Do not connect both cords to the same outlet.”
3Attach the priming hose to the machine and place the open end into the solution tank.
4Turn ON the solution pump (A) and let it run until the pump is fully primed (approximately 30 seconds to 1 minute). Once
the pump is primed, turn off the pump and remove the priming hose.
5 Connect a solution line to the Solution Hose Quick Disconnect (1). Attach the other end of the solution line to the cleaning
tool.
NOTE: If there is pressure built up in the solution lines, it may be difcult to connect a solution line to the Quick
Disconnect (1). If this is the case place the Pump Switch (A) into the OFF (O) position. Momentarily turn the Pressure Relief
Valve (16) from the green “checkmark” position to the red “X” position and back again to the green “checkmark” position, this will
relieve the pressure to allow a solution line to be connected to the quick disconnect port.
CAUTION!
Always operate the machine with the Pressure Relief Valve set to the Green “checkmark” position to avoid
possible damage.
6Connect a vacuum hose to the Vacuum Hose Barb (3). Attach the other end of the vacuum hose to the cleaning tool.
7To use heated water for cleaning, press the Heat Switch (E) into either the Low Temperature position (I) or the High
Temperature position (II). Wait two minutes for the heat exchanger to reach temperature.
8 Press the Pump Switch (A) to ON (I).
9 Press the Vacuum Switches (B &C) to ON (I). The machine can be used with only one vacuum motor running for less
suction i.e. cleaning upholstery.
10 Spray through your tool a few times to ll the lines with solution. Begin cleaning.
11 To adjust the solution spray pressure; rotate the Pressure Adjustment Knob (14) clockwise to increase pressure and
counterclockwise to decrease pressure. The pump spraying pressure will be observable at the Pressure Gauge (15) while
spraying. Make sure the cleaning tool is spraying when adjusting the pressure, otherwise the pressure reading will be
inaccurate.
12 Watch the uid entering the Recovery Tank Lid (11). If there is a large amount of suds in the recovery tank, add a
defoamer chemical (SERVPRO Defoamer item #151) to the recovery tank.
CAUTION!
• Empty the recovery tank before the uid or foam enters the vacuum motor.
• If foam or liquid escapes from the machine, switch off immediately.

13 - RX-20 / CMX-20 Owner’s Manual13 - PEX 500 - SP Owner’s Manual
CAUTION!
Always make sure the oat is clean and travels freely before turning on the machine. A oat that is stuck
will cause the vacuum motor to suck in water, resulting in vac motor damage.
13 The recovery tank has a Recovery Tank Shutoff Float (10) to block the vacuum system when the recovery tank is full.
You can tell when the oat closes by the sudden change in the sound of the vacuum motor. When the oat closes, the recovery
tank must be emptied. The machine can continue to dispense solution, but will not pick up water with the oat closed.
14 Monitor the water level in the solution tank. Do not let the pump run dry. When the solution tank gets low, turn off the
pump and the vacuum motor(s), rell the solution tank with water and the proper ratio of cleaning detergent. Empty the recovery
tank and continue cleaning.
15 When the operator has completed the job; vacuum all unused solution from the solution tank into the recovery tank,
turn off the pump, vacuum motor(s) and heat exchanger. Unplug the machine.
16 Push the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, loosen the
Velcro strap retaining the Recovery Tank Drain Hose (4) into its side storage location, then remove the plug (hold the end of the
hose above the water level in the tank to avoid sudden, uncontrolled ow of waste water).
17 Follow the instructions in the After Using the Machine section of this manual.

AFTER USING THE MACHINE
See the diagrams on pages A-9, A-10 and A-14.
1To empty the solution tank, open Solution Tank Fill Opening (2) and vacuum out all unused solution into the recovery
tank using the vacuum hose. Rinse the tank with clean water.
2Turn all the Power Switches (A, B, C & E) to OFF (O). Unplug the Power Cords (20). Coil the cords and secure them
to the rear of the machine using the four Cord Retainer Straps (17).
3To empty the recovery tank, loosen the Velcro strap retaining the Recovery Tank Drain Hose (4) into its side storage
location. Direct the hose to a designated waste water “DISPOSAL SITE” and remove the plug (hold the end of the hose above
the water level in the tank to avoid sudden, uncontrolled ow of waste water). Rinse the tank with clean water. Inspect the drain
hose; replace if kinked or damaged.
4Disconnect the solution and vacuum hoses from the machine, at the Solution Hose Quick Disconnect (1) and Vacuum
Hose Barb (3) respectively. Flush the vacuum hose with warm water to wash any debris out of the vacuum hose and cleaning
tool. Inspect them for damage. Fold down the Hose Hangers (21) and the hoses can be wrapped around the machine for
storage. Set the wand on the Wand Retainer Bracket (19) and secure to the back of the machine at the Wand Storage Clip (13).
