Frequently Asked Questions - Lite 8070-SS Mytee

What is the power requirement for the Mytee Lite 8070-SS?

The machine requires a grounded 20 amp outlet at 115V. It draws 19 amps and has a 25-foot power cord. Do not use extension cords.

How do I properly start the Mytee Lite 8070-SS to avoid vapor lock?

Turn on the pump switch first, then pull the cleaning tool lever until water flows steadily. Next, turn on the heater switch and wait a few minutes. Finally, turn on the vacuum switch and begin cleaning.

What tanks does the machine have and how do I empty them?

It has a 4-gallon solution tank and a 4-gallon recovery tank. The solution tank drain is on the front lower left; the recovery tank drain is on the back bottom. Use the included drain hose to empty into a bucket.

How often should I clean the filters?

The filter on top of the vacuum stack in the recovery tank should be checked and cleaned after each use. Additionally, internal filters should be inspected weekly.

What is the recommended maintenance for the solution system?

Weekly, flush the solution system with Mytee System Maintainer (part #3601). Mix 1 quart of maintainer with 1 quart of warm water, run through the machine with the pump on, then rinse with clean warm water.

Why is my vacuum not producing suction?

Possible causes include a full recovery tank, disconnected or blocked vacuum hose, clogged filter, loose drain valve/cap, or loose lid. Check and tighten connections, empty the tank, and clean the filter.

What should I do if the pump runs but no spray comes out?

Check for blockages or kinks in the line. Air in the pump can be cleared by priming: remove the quick disconnect and ensure the clip is aligned. If the unit is new, the check valve may be stuck; remove and clean or replace it.

How do I troubleshoot the heater if it's not heating?

Check electrical connections and reset the manual sensor button. If the heater still doesn't work, test the element continuity and check the switch. Also ensure the pump is on before the heater to avoid vapor lock.

Can I use the Mytee Lite 8070-SS for dry vacuuming?

No, do not dry vacuum. Dry vacuuming can suck debris into the vacuum motor, causing damage and loud grinding noises. Always use the machine for wet extraction.

Where can I find replacement parts or service?

Contact an authorized Mytee Products Service Center. For an updated list, visit www.mytee.com/support/service-centers. Have your model and serial number ready, found on the back near the power plugs.

Grounding Instructions

This machine must be grounded. If it should malfunction or breakdown, 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 code and ordinances. Do not remove ground pin; if missing, replace 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 nor 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 Figure 2 & 3 to install a temporary-grounding plug. This temporary work-around 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 America use only.

2.3 - Filling the Solution Tank

The Mytee Lite™ solution tank can be filled up via the faucet fill hose or from a bucket via the opening.

2.4 - Operating the Mytee Lite™

Switching On The Unit

In order to avoid vapor locking the unit, the Mytee Lite's™ components should be switched on by following the procedure below:

1. Turn pump switch on.
2. Pull the lever on the cleaning tool to release air in the line. Hold lever until a steady flow of water comes out of the wand.
3. Once pump is primed and there is pressure in the solu-

tion line, turn on heater switch and wait a few minutes for water to heat up.

1. Once water is heated, turn on vacuum and begin cleaning.

Note: When cleaning upholstery, always check manufacturer's cleaning instructions.

Cleaning With The Mytee Lite™

For best results when extracting, do one wet pass followed by two dry passes. This ensures you're not over-soaking the material and also gives the heater time to catch up.

2.5 - Emptying the Solution & Recovery Tanks

The solution tank drain is located on the front, lower left corner of the solution tank.

The recovery tank drain is located on the back of the machine at the bottom of the recovery tank. Attach the included recovery tank drain hose in order to easily empty into a bucket or other receptacle.

3 - Machine Maintenance

In order to keep the Mytee Lite™ running smoothly and reduce the risk of damage to the machine and subsequent downtime, Mytee recommends following the maintenance schedule below:

Maintenance Item Daily Weekly
Clean and inspect tanks. X
Clean and inspect hoses. X
Check and clean internal filters. X
Check power supply cable. X
Clean machine with all-purpose cleaner and cloth.	X
Check spray nozzles. X
Flush solution system with Mytee System Maintainer.		X
Inspect vacuum hoses for holes and loose cuffs.		X
Inspect spray pattern for clogging. If clogged, remove spray tips and soak them in a recommended liquid neutralizer for up to six hours. To remove spray tip, twist spray tip body counter-clockwise.		X
Lubricate wheels with water resistant oil.		X
Inspect machine for water leaks and loose hardware.		X

3.1 - Filter Maintenance

The Mytee Lite™ has a small filter on the top of the vacuum stack in the recovery tank. This filter should be checked and cleaned after each use.

3.2 - 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 solution through your cleaning tool. NOTE: The jet should be removed from the cleaning tool in order to prevent clogging due to loosening of deposits in line.
4. Next, turn on the heater. 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 solution 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.

5.1 - Vacuum Troubleshooting

Vacuum is not turning on.
Possible Cause Solution
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 tagging 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.

Vacuum is not producing suction.
Possible Causes Solutions	the recovery tank.
Recovery tank is full. Empty	Open the machine and find the hose running from 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").
If the vacuum exhausts but there is no suction, then the hose from the recovery tank to the vacuum motor is disconnected.
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 vacuum tank.	Clean out filter regularly.
Drain valve/cap is loose and is causing air leakage.	Tighten the drain valve/cap.

Hose cuffs are loose and causing air leakage.	Tighten all hose cuffs regularly as may loosen over time. Use a glue to prevent cuffs from coming loose (optional).
Lid on tank is loose and is causing air leakage.	Make sure the lid is tight.

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 problem,DO NOT dry vacuum with your extractor.

5.2 - Pump Troubleshooting

Pump doesn’t turn on.
Possible Causes Solutions
Bad switch at 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.

Pump runs but there is no spray.
Possible Causes Solutions
Blockage or kink somewhere in the line.	See 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.

Pump runs but there is no spray.
Possible Causes Solutions
On a new unit, the check valve between the pump and heater may hang up, causing the flow of water to be impeded or stop entirely.	Remove the check valve temporarily and check to see if the pump will flow water out of the pump outlet hose when the pump is turned on for a brief instant in order to verify cause.The remedy is to install a new check valve. Observe the proper orientation (flow direction) of the check valve.Tip: the check valve may be able to be temporarily returned to service by un-sticking the check valve poppet with manipulation of the poppet ball with a thin tool, like a straightened paperclip. Replace the check valve in unit assembly.NEVER OPERATE A UNIT WITHOUT A CHECK VALVE IN PLACE.

Pump runs for a second then shuts down.

Possible Causes Solutions

QD is pressure locked. Relieve pressure from behind the QD by pressing in 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.

5 - Troubleshooting

Pump doesn’t stop running.
Possible Causes Solutions
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 on, open the machine and check for leaks. Repair the leak. If there are no leaks, run Mytee’s System MaintainerTM (Part # 3601) through the machine to clear blockages.
Cracks or vacuum leaks on inlet side of 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 chemical.	Install seal repair kit.
Debris blocking inlet filter or pump head.	Clean filter and/or pump head.

Pump trips circuit breaker when turned on.

Possible Causes Solutions

Short in power switch. Test by swapping vacuum and pump switch. If problem resolves, but vacuum begins tripping breaker, replace switch (Part #E515).

Short in electrical harness. Risk of electric shock. Do this at your own risk.Remove pump from circuit by attaching power leads together. If breaker still pops when switch is toggled, then there is a short to the ground in the circuit. Replace wires as needed.

Short in pump motor. If switch

h and harness check is OK, the short may be in the pump motor. Re-place pump.

5.3 - Heater Troubleshooting

Heater is not heating water.
Possible Causes Solutions
Loose electrical connection.	Check all electrical connections, including power cord and harness.
Automatic sensor has failed, causing 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 heater continues to trip the manual sensor, replace the automatic sensor (Part #E573) on the heater.
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 flowing 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.
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.
Water in 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.
Heater has hard water buildup inside, leading to lost efficiency.	Run Mytee System Main-tainerTM (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.

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 machine has cooled, turn on the pump first. Prime the unit by spraying solution out of the cleaning tool. Then, turn on the heater.
