Important Safety Information
This machine must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electrical shock. This machine 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 in accordance with all local codes and ordinances. Do not remove the ground pin; if missing, replace the plug before use.
Improper installation of the equipment-grounding conductor can result in a risk of electric shock. Be sure to check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. If the plug will not fit in the outlet do not modify either the plug or the machine’s cord, instead have a proper outlet installed by a qualified technician.
This machine is for use on a nominal 120-volt circuit and with a grounding plug similar to the one in Figure 1 below. If a proper outlet is not available, follow the illustrations of Figures 2 & 3 to install a temporary-grounding plug. This temporary workaround should be used only until a proper outlet (Figure 1) can be installed by a qualified electrician. When and if this type of adapter is employed, screw the adapter’s extended tab into place with a metal screw.
However, grounding adapters are not approved for use in Canada.
Again, be sure to check the grounding pin for damages and replace if necessary.
The Green, or Green-Yellow, wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to only the grounding pin.
DO NOT use extension cords.
Please Note for American use only.

Powering the Prep Center S
To power, the Prep Center S, plug the power cord into a grounded 20 amp outlet.♦
Connecting Vacuum and Solution Hoses
Do not operate the machine with a spray nozzle orifice smaller than #2. This can damage the pump switch.
Do not pull on hoses in order to move the unit. Use only the appropriate handles.
Connect the vacuum hose via Cuff-Lynx™ connector to clear the elbow on top of the machine. Simply twist the male Cuff-Lynx™into the elbow. Connect the solution line to the female solution quick connect fitting on the switch plate. ♦
Connecting Shop Air Line
Shop air input is located in the bottom-right corner of the rear of the machine.
Output is located on the switch plate. ♦
Do not use an air source higher than 30 PSI. This can cause damage to hoses.
Filling the Solution Tank
The solution tank can be filled from a standard faucet or hose bib. Simply lift the Faucet Fill hose out of the tank and press it against the faucet. Turn on the faucet to allow water to flow into the tank.
Fill up a bucket with water and pour it into the solution tank through the opening on top of the machine. Add the desired chemical according to manufacturer specifications.♦
IMPORTANT: DO NOT dry vacuum without a Piglet™ Filter in place on the strainer basket. This will cause damage to the vacuum motor.
- Attach a vacuum hose to the clear elbow.
- Switch on the vacuum and begin vacuuming.
- Replace the Piglet™ filter regularly. ♦
Hot Water Extraction with the Prep Center S
To avoid a vapor lock, follow this procedure when turning on the machine for hot water extraction.
- Turn the PUMP switch on. Pull the lever on the cleaning tool to release air in the line. Hold the lever until a steady flow of water comes out of the tool.
- Turn on the HEATER switch and wait a few minutes for the water to heat up.
- Once water is heated, turn on VACUUM and begin cleaning. ♦
Use only low foam or nonfoaming detergent or shampoo. Damage due to excessive foam will void the warranty.
Empty the vacuum tank any time you refill the solution tank in order to prevent vacuum tank overfilling.
Using the Blower Attachment
Attach vacuum hose via Cuff-Lynx™ adapter to the blower port on the front of the machine in the bottom-right corner. Switch on the VACUUM. The blower attachment uses the exhaust from the vacuum for drying. ♦
Using Auxiliary Chemical Bottles
Put the desired chemical in the bottle(s) to be used. Connect shop air to the air line input quick connect in the bottom right corner of the rear of the machine. Once the bottle(s) are pressurized, chemicals can be sprayed using the attached nozzles. ♦
Emptying the Recovery Tank
Pull up on the drain valve handle on the rear of the machine to drain the recovery tank into a bucket or drain. ♦
When storing the Prep Center S, make sure all liquid is purged from the system and the tanks are drained. This is especially important in cold climates. ♦
In order to keep the Prep Center S running smoothly and reduce the risk of damage to the machine and subsequent downtime, Mytee recommends following the maintenance schedule below:

|Lubricate casters with water-resistant oil.||X|
|Inspect the machine for water leaks and loose hardware.||X|
Opening the Unit for Maintenance
To open the Prep Center S, loosen the rear latches by turning them one quarter turn counter-clockwise. Flip the latches down and then lift up on the push handle and the machine will open up. ♦
The Prep Center S has a small filter at the top of the vacuum stack in the recovery tank. This filter should be checked after each use. ♦
Regular flushing of the solution system with the Mytee System The maintainer keeps your extractor running efficiently by removing hard water scaling that builds up in the system.
How to use System Maintainer:
- Thoroughly mix System Maintainer with warm water at a 1:1 ratio in a separate container. Pour into your Extractor’s solution tank.
- Connect a cleaning tool (upholstery tool, wand, etc.) and remove the jet(s) in order to prevent clogging from dislodged mineral build-up.
- Turn on the Extractor’s pump and run the System Maintainer solution through the system and into a bucket or receptacle until you have a solid stream.
- Let sit for about 5 minutes while the System Maintainer solution does its job inside your Extractor.
- Finish running the rest of the solution through the system.
- Run clean water through the system to flush out any remaining System Maintainers.♦
