Introduction

Dear Customer:
Congratulations on the purchase of your new Grand Prix™ Automotive Detailing Extractor. As technology continues to develop you can work confidently knowing that both Mytee and its employees are equally dedicated to developing with the industry and its advances.

Like any other piece of machinery or technology, the Grand Prix™ also requires proper maintenance and care to keep the product working over extended use. Neglecting your machine, abusing it, or not operating it properly can void its warranty and prevent the machine from performing to the quality and standard you’d expect out of the Mytee line.

If you have any warranty concerns or questions, please review this manual thoroughly or do not hesitate to contact your distributor. If there are questions regarding maintenance, replacement, or ordering parts please contact an authorized Mytee Service enter. Visit www.mytee.com/support/find-distributors to find your nearest Service Center. Before using your Mytee product, please read this manual thoroughly.

Sincerely,
Mytee Customer Care Dept.

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.

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 3 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 in 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.

2.2 – Filling the Solution Tank

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 11

Lift the tank lid and, using a bucket, fill the solution tank via the large opening. For best results, use warm water.

2.3 – Connecting the Hoses

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 12 CAUTION
Do not operate the machine with a spray nozzle orifice smaller than #2. This can damage the pump switch.

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 13 CAUTION

2.4 – Operating the Grand Prix™

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 15

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 tool.
  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.

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 16 CAUTION
Use only low foam or nonfoaming detergent or shampoo. Damage due to excessive foam will void the warranty.

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 17 CAUTION
Empty the vacuum tank any time you refill the solution tank in order to prevent vacuum tank overfilling.

Cleaning Procedure
For best results when extracting, do one wet pass followed by two dry passes. This ensures you’re not over-soaking the material and keeps the water temperature higher. The solution pump will only turn on when there is a pressure demand (e.g., while spraying with a cleaning tool, or right at startup). If the pump is continuously running or pulsing, it does not necessarily mean that it is defective. If the pump is not producing the correct pressure and flow, see the Troubleshooting section of this manual.

2.5 – Emptying the Tanks
Empty the recovery tank via the drain valve on the rear of the machine. Make sure there is a bucket in place under the valve or the machine is in a position so the dirty water is
drained safely. Any leftover solution in the solution tank can be sucked out of the tank using the vacuum hose and drained from the recovery tank.

3.2 – Filter Maintenance
The Grand Prix™ has a small filter at the top of the vacuum stack in the recovery tank. This filter should be checked after each use.

3.3 – System Maintainer
Regular flushing of the solution system with Mytee System Maintainer keeps your extractor running efficiently by removing hard water scaling that builds up in the system.

How to use System Maintainer:

  1. Thoroughly mix System Maintainer with warm water at a 1:1 ratio in a separate container. Pour into your Extractor’s solution tank.
  2. Connect a cleaning tool (upholstery tool, wand, etc.) and remove the jet(s) in order to prevent clogging from dislodged mineral build-up.
  3. 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.
  4. Let sit for about 5 minutes while the System Maintainer solution does its job inside your Extractor.
  5. Finish running the rest of the solution through the system.
  6. Run clean water through the system to flush out any remaining System Maintainers.

MYTEE HP120 Grand Prix Hot Water Extractor User Manual  & troubleshooting 19 CAUTION

Troubleshooting

Issue

Possible Cause

Solution

The machine is not turning on. The power cord is unplugged. Plug the power cord into a grounded 20 amp outlet.
The circuit breaker tripped in the building. Reset breaker in the building.
Faulty switch or power cord. Contact a Mytee Service Center.

Blockage or clog in solution line. Run System Maintainer through the machine.
The pump continuously runs/pulses without producing correct pressure/ flow. Leak in solution line between pump and cleaning

tool.

Find a leak and repair or replace the hose if necessary.
Pump switch failure. This can be caused by various issues:
• Nozzle tip clogged or too small, causing rapid switch cycling.
• Check valve failure between pump and heater causing hot water to return to pump and damage switch.
• Pump inlet port is cracked causing the pump to suck in air.
• Damaged pump switch housing.
Contact a Mytee Service Center.
Water is not pumping out of the machine. Bad power switch.

Check the power switch by transferring wires from the switch in question to another switch. See if that
switch turns on the component in question. Replace
switch if necessary.

Vacuum/pump/ heater not turning on. Bad power switch.

Check the power switch by transferring wires from the switch in question to another switch. See if that
switch turns on the component in question. Replace
switch if necessary.

Vacuum not

producing suction.

The vacuum tank is full. Empty vacuum tank.
Vacuum hose blockage. Check for blockages in vacuum hoses inside and outside the machine.
Blows water out of the exhaust. Foam building up inside vacuum tank. Use a defoaming solution in a vacuum tank or use low foam or nonfoaming detergent/shampoo.
The water is not getting hot. Automatic (black) sensor failure causes the manual (white) sensors to trip. Reset the manual (white) sensor by pressing the small button on it. If the manual sensor continues to trip, replace the automatic (black) sensor (part no. E573).
