Important Safety Information

Please read and understand this manual completely before operating this machine.

Grounding Instructions
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.

DANGER
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 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 it 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.

Parts and Service
Please contact Mytee service personnel or a Mytee authorized Service Center using Mytee’s original replacement parts and accessories if repairs need to be performed. When and if calling Mytee for support, please have your Model and Serial Number available for faster assistance.

Name Plate
The Model and Serial Number are located on the lower half of the back of the machine near the power plug and will be required for ordering replacement parts. You can use the space provided in this manual to note down both for future reference.

Unpacking the Machine
When your new machine is delivered, please carefully inspect both the shipping carton and the machine for damages. If damage is evident, save both the shipping carton and machine so that the delivering carrier can inspect it. Contact the carrier immediately to file a freight claim if there has been any damage.

2.2 – Connecting Vacuum & Solution Hoses

IMPORTANT: Do not pull on hoses in order to move the unit. Only use the appropriate handles.

Use the included Cuff-Lynx™ hose connectors to connect a 1.5” or 2” vacuum hose to the Speedster® LTD. Connect the solution hose via the quick connect fitting on the front of the Speedster® LTD.

2.3 – Filling the Solution Tank

The Speedster® LTD solution tank can be filled up from a bucket via the opening under the solution tank lid or via the auto-fill feature (section 2.5).

IMPORTANT: Use only low foam or nonfoaming detergent or shampoo. Damage due to excessive foam will void the warranty.
IMPORTANT: Do not use acid (acid rinse) or high alkaline chemicals like sodium hydroxide in the LTD3 or LTD5-LX machines. This will cause damage to the pump and void the warranty.

2.4 – Switching on the Speedster® LTD
Units Without Heater (LTD5-LX, LTD12, LTD12-LX)
After cleaning, the tool is connected and the solution tank is filled, switch on the vacuums and the pump in any order.

Units With Heater (LTD3)

In order to avoid vapor locking the unit, the components should be switched on by following the procedure below after a cleaning tool is connected:

  1. 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 wand.
  2. Once the pump is primed and there is pressure in the solution line, turn on the heater switch and wait a few minutes for the water to heat up.
  3. Once water is heated, turn on the vacuum and begin cleaning.

2.5 – Chemical Injection

Fill the included 5 qt. bottle with the chemical concentration of your choice. With a cleaning tool connected, switch on the pump and pull the trigger on your tool to keep water flowing. Turn the chemical injection knob counter- clockwise to open the valve. This allows chemicals to siphon into the line. Turn the knob until you see the bubble reach the desired gallons per hour of chemical. Follow the chemical manufacturer’s instructions for the correct ratio.

IMPORTANT: If the chemical injection will not be used, make sure the chemical injector is closed by turning the knob all the way clockwise. ♦

2.6 – The Auto-Fill & Pump-Out Features
Auto-fill: Connect standard garden hose from water source to LTD auto- fill connection. Turn on the water source and let the tank begin to fill. It will shut off when the water level reaches the float switch in the solution tank.

Pump-out: Connect a second standard garden hose to the LTD’s pump-out connection and lay the other end of the hose in a drainable location. Activate the pump-out switch on the front of the machine and open the ball valve on the pump-out connection. The LTD will automatically drain recovered water from the tank.

2.7 – The Prime Valve

The Speedster® LTD units come with a prime valve attached to the solution hose quick connect fitting. Turning the valve lever to position 1 directs flow towards the wash
hose inside the solution tank. Turning the lever to position 2 directs flow towards the cleaning tool.

2.8 – Emptying the Recovery Tank

Empty the recovery tank by attaching the H226 45˚ drain elbow to the drain spout in the back. Lift up the dump valve and empty the tank into a bucket or drain.

Rinse out the recovery tank using the wash hose inside the solution tank. Take the lid off the recovery tank and place the end of the wash hose inside. With solution or clean
water in the solution tank, switch on the pump and turn the prime valve to position 1 (shown in section 2.6). Rinse off the inside of the recovery tank and then drain the tank.

2.9 – Emptying the Solution Tank

The Speedster® LTD has a solution tank drain cap on the back of the machine. Just unscrew this cap to drain unused solution into a bucket or other receptacle.

3.1 – Opening the Unit for Maintenance

To open the Speedster® LTD, 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.

3.2 – Filter Maintenance
The Speedster® LTD comes with a nylon mesh bag filter that should be placed over the pump-out filter on the bottom of the recovery tank. The nylon bag filter, the pump-out filter, and the solution filter inside the solution tank should be checked and cleaned on a daily basis.

3.3 – Ball Float Maintenance
The ball floats in the recovery tank to prevent recovered dirty water from rising too high and damaging the vacuum motors. Clean the mesh screen on the floats regularly.

3.4 – System Maintainer
Weekly flushing of the solution system with Mytee® System Maintainer helps keep lines clean and prevents chemical build-up, improving pump life, performance, and pressure.

How to use System Maintainer:

  1. Mix 1-quart 3601 System Maintainer with 1-quart of warm water.
  2. After thoroughly mixing, pour this solution into the solution tank.
  3. Turn the pump on FIRST, and run the solution through your cleaning tool. NOTE: The jet should be removed from the cleaning tool in order to prevent clogging due to the loosening of deposits in line.
  4. Next, turn on the heater (if equipped). If the heater is turned on first, it will result in a vapor lock, which will affect the machine’s operation.
  5. Next, with both the pump and heater on, begin running the solution through the machine. This allows the solution to break down any build-up in the lines.
  6. After running all of the solutions through the machine, fill the tank with clean, warm water. Run the water through the machine to clear the solution completely out of the tank & lines.

Troubleshooting

5.1 – Vacuum Troubleshooting

The vacuum is not turning on.


Possible Cause

|

Solution

The vacuum may not be getting power.|

Check the electrical connections and the switch. Look for loose or damaged wires.
To check the switch: Unbolt the switch plate. Take a picture of the layout of the wires or tag the wires for future reference.
Switch the wires from the vacuum switch with the wires from either the pump or heater switch.
Turn on the pump or heater switch (whichever one you exchanged wires with). If the vacuum turns on, then you know the vacuum switch is bad.

The vacuum is not producing suction.


Possible Causes|

Solutions

The recovery tank is full.| Empty the recovery tank.
If the vacuum exhausts but there is no suction, then the hose from the recovery tank to the vacuum motor is disconnected.| Open the machine and find the hose running from the recovery tank to the vacuum motor. Check if it is disconnected. If so, reconnect it. If it has a leak, replace the hose ( **Part

PH627 if 1.5”, PH628 if 2”** ).

Vacuum hose blockage (if there is no suction or exhaust).| Check for blockage in the hose, starting from the cleaning tool to the machine.
Clogged filter in a vacuum tank.| Clean out the filter regularly.
The drain valve/cap is loose and is causing air leakage.| Tighten the drain valve/cap.
Hose cuffs are loose and cause air leakage.| Tighten all hose cuffs regularly as may loosen over time. Use glue to prevent cuffs from coming loose (optional).
The lid on the tank is loose and is causing air leakage.| Make sure the lid is tight.
---|---

The vacuum blows water out the exhaust.


Possible Causes|

Solutions

Foam building up in the recovery tank.| Use a defoaming solution in the recovery tank.

There is a loud grinding noise coming from the vacuum.


Possible Cause|

Solution

Debris has been sucked into the vacuum motor chamber. Usually results from dry vacuuming.| Replace the vacuum motor. To avoid repeat problems, DO NOT dry vacuum with your extractor.

5.2 Pump Troubleshooting

The pump doesn’t turn on.

Possible Causes|

Solutions

Bad switch at the control panel.| Unbolt the switch plate. We recommend taking a picture of the layout of the wires or tagging the wires for future reference. Switch the wires from the pump switch with the wires from either the vacuum or heater switch. Turn on the vacuum or heater switch (whichever one you exchanged wires with). If the pump turns on, the pump switch is bad.
Loose or disconnected wire.| Disconnect the power cord from the electrical outlet.
Open up the machine and look for any loose or disconnected wires. Re-attach or replace wires.
The pump runs but there is no spray.

Possible Causes| Solutions
Blockage or kink somewhere in the line.| See the chart on page 4 of the Diaphragm Pump Troubleshooting Guide to diagnose the location of the blockage.
Air is in the pump.| Prime the pump.
Remove QD off the machine and solution hose. Make sure that the three-prong clip on the inside of the threaded end is evenly aligned below the thread of the QD.
The pump runs but there is no spray.

Possible Causes| Solutions

The pump runs for a second and then shuts down.

Possible Causes| Solutions
QD is pressure locked.| Relieve pressure from behind the QD by pressing the button inside the QD.
Low PSI.

Possible Causes| Solutions
The jet nozzle could be too large.| Replace the jet with one that has a smaller opening.
The pump doesn’t stop running.

Possible Causes| Solutions
A leak somewhere in the line.| Disconnect the solution hose from the machine. If this causes the pump to stop running then the problem is outside the machine, either in the solution hose or tool. If it continues running, open the machine and check for leaks. Repair the leak. If there are no leaks, run Mytee’s System Maintainer™ ( Part # 3601 ) through the machine to clear blockages.
Cracks or vacuum leaks on the inlet side of the pump.| Make sure hoses are secured tightly. If the inlet side of the pump is cracked or damaged, replace the pump.
Seals have been degraded by chemicals.| Install seal repair kit.
Debris blocking inlet filter or pump head.| Clean filter and/or pump head.
The pump trips the circuit breaker when turned on.

Possible Causes| Solutions
Short in power switch.| Test by swapping vacuum and pump switch. If the problem resolves, but the vacuum begins tripping the breaker, replace the switch ( Part #E515 ).
Short in electrical harness.| Risk of electric shock. Do this at your own risk.
Remove the pump from the circuit by attaching power leads together. If the breaker still pops when the switch is toggled, then there is a short to the ground in the circuit. Replace wires as needed.
---|---
Short in the pump motor.| If the switch and harness check are OK, the short may be in the pump motor. Replace pump.

5.3 Heater Troubleshooting

A heater is not heating water.

Possible Causes| Solutions
Loose electrical connection.| Check all electrical connections, including the power cord and harness.
The automatic sensor has failed, causing the manual sensor to trip.| Reset the manual sensor button by pressing the small white and yellow button in the center of the sensor. If this works, but the heater continues to trip the manual sensor, replace the automatic sensor ( Part #E573 ) on the heater.
The heater element has failed.| Check for continuity through the element by reading the amperage. If amps are low, only part of the element may be heating up – in this case, the element is damaged and needs to be replaced.
Bad power switch.| If the element, sensors, and wiring all check out okay, there may be a bad switch on the switch plate.
Running out of hot water too fast.

Possible Causes| Solutions
Too much water flows through the heater.| Remember, when using your machine, it is recommended you do one wet pass followed by two dry passes. This way you are not spraying as much and the hot water will last longer.
The jets being used are too large.| If your machine has a 1,000W or 1,200W heating system, make sure your cleaning tool has 0.02 jets.
The water in the tank is very cold.| If possible, fill your solution tank with warm water in order to shorten the amount of time it takes for the water to heat up. The pumps are usually rated for 140°F water.
The heater has hard water buildup inside, leading to lost efficiency.| Run Mytee System Maintainer™ ( Part # 3601 ) through the machine regularly in order to clear hard water or chemical residue that can block water flow and reduce heating ability. See product label for instructions.
The unit has vapor-locked and there is no water pumping out of the unit.

Possible Cause| Solution
Turning on the heater before turning on the pump and priming the unit.| Turn off the heater and allow the unit to cool completely. When the machine has cooled, turn on the pump first. Prime the unit by spraying the solution out of the cleaning tool. Then, turn on the heater.
