Grounding Instructions
THIS PRODUCT IS FOR COMMERCIAL
USE ONLY.
ELECTRICAL:
In the USA this machine operates on a standard 15 amp 115V, 60 hz, A.C. power circuit. The amp, hertz, and voltage are listed on the data label found on each machine. Using voltages above or below those indicated on the data label will cause serious damage to the motors.
EXTENSION CORDS:
If an extension cord is used, the wire size must be at least one size larger than the power cord on the machine, and must be limited to 50 feet (15.5m) in length.
GROUNDING INSTRUCTIONS:
This appliance must be grounded. If it should malfunction or break down, 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 inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
This appliance is for use on a nominal 120-volt circuit, and has a grounded plug that looks like the plug in "Fig.
A". A temporary adapter that looks like the adapter in
"Fig. C" may be used to connect this plug to a 2-pole receptacle as shown in "Fig. B", if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet (Fig. A) can be installed by a qualified electrician. The green colored rigid ear, lug, or wire 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.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
Check with a qualified 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 fit the outlet, have a proper outlet installed by a qualified electrician.
Le raccordement incorrect du conducteur de terre d'équipement peut entraîner des risques d'électrocution. Vérifiez auprès d'un électricien qualifié ou d'un responsable de l'entretien si vous avez quelque doute que ce soit quant au raccordement à la terre de votre prise murale. Ne modifiez pas la fiche fournie avec l'appareil : si elle ne correspond pas à la prise murale, faites installer une prise adéquate par un électricien qualifié.

Operations
Pre-Run Inspection
1. Check all fittings and connectors for proper assembly.
2. Check all hoses for leaks. Repair or replace any damaged hoses.
3. Check power cord(s) for any damage. If damaged, replace.
Equipment Set-up
1. Plug power cord from machine into properly grounded wall outlet.
2. Turn vacuum motor switch on and off to make sure there is electrical power at machine.
3. Using a clean container, fill the solution tank with clean hot water. Do not use water over 130°F. Mix in a non-foaming cleaning concentrate for use in hot water extraction machines, following the manufacturer's instructions printed on container.
4. Connect priming hose to solution fitting on machine. Turn on pump and run for 30 seconds or until a steady flow of water is coming out of priming hose. Turn off pump and disconnect priming hose.
5. Connect vacuum hose to machine. Slide the swivel cuff over the outlet on the tank.
6. Connect the hose to your machine and wand. Pull back the knurled collar on the quick disconnect coupler and push onto the connection on the chassis. To avoid leaks, check to be that a positive connection was made.
NOTE: When using a powder cleaner, pre-mix with hot water in a clean container before adding to the solution tank.
7. Turn pump and vacuum switch(es) to the on position.
Heater Operation
NOTE: Units with Heat Only
The solution fittings on the machine will become extremely hot during operation. Allow sufficient time to cool, or run solution through the machine with the heater turned off before disconnecting or performing any maintenance on the heater.
Les pièces de fixation de la machine deviennent très chaudes pendant le fonctionnement. Prévoyez suffisamment de temps pour refroidir, ou laissez couler la solution à travers la machine avec le réchauffeur éteint avant de débrancher ou d'effectuer toute opération d'entretien sur le réchauffeur.
1. Plug the two power cords into separate grounded circuits. The heater draws 15 amps of current.
2. Turn the solution pump
ON
. Fully prime the solution system before turning heater on.
3. Turn the heater switch on. The red light on the heater switch will be on when the heater switch is on. The red heater temperature light will be on when the heater is active and will turn off when the heater reaches maximum temperature.
On initial start-up the heater will take a few minutes to reach operating temperature.
When turning the pump and heater
OFF
, make certain that you turn the heater off
FIRST
.
14 86399050 Operators Manual - Dominator 500 PSI 13 gallon
Operations
Always use defoamer if foaming occurs. Foam will suspend large particles that may damage vacuum(s) as well as allow liquid into the vacuum motor(s) without activating the float shutoff.
Utilisez toujours des anti-mousses, en cas de formation de mousse. La mousse suspendra les grosses particules qui peuvent endommager l'aspirateur et laissera le liquide s'écouler dans le moteur de l'aspirateur sans entraîner l'arrêt du flotteur.
1. Prior to cleaning, make certain that the nozzle is functioning properly.
a. To check, hold the wand about one foot above the surface to be cleaned and open the wand valve. A full spray should be observed from the nozzle.
b. If the nozzle is not showing a full spray pattern, adjust nozzle for proper pattern, clean, or replace nozzle.
2. Normally, chemical is applied on the push stroke of the wand when cleaning. Vacuuming is done on the pull stroke. For heavily soiled carpets the wand may be used in a scrubbing manner, applying chemical in both the push and pull stroke.
3. When cleaning, keep the working opening (wand mouth) flat on the surface being cleaned. Keep the wand moving when the valve is open.
4. The shutoff float inside the vacuum tank will impede the vacuum flow when the vacuum tank is full. When this occurs, empty the vacuum tank by opening the dump valve and dispose of the waste in a proper manner.
5. Once the vacuum tank has been emptied, you may once again proceed with cleaning
86399050 Operators Manual - Dominator 500 PSI 13 gallon 15
Maintenance
Periodic Maintenance
Twice a month, flush a white vinegar solution (one quart vinegar to two gallons of water) or anti-browning solution (mixed as directed) through the machine. This will prevent build-up of alkaline residue in the system.
Periodically inspect all hoses, electrical cables and connections on your machine. Frayed or cracked hoses should be repaired or replaced to eliminate vacuum or solution pressure loss. The electrical cable must be well insulated and cable connector screw kept tight. If the cable insulation is broken or frayed, repair or replace immediately. Don't take chances with electrical fire or shock.
Daily/Regular Maintenance
Before making any repairs or adjustments to the machine, disconnect the power cords from the electrical source.
Retirez le cordon d'alimentation de la machine de la source électrique avant de procéder à des réparations ou des ajustements de la machine.
1. Empty unused cleaning solution from the solution tank.
2. Inspect and clean filter screen in solution tank.
3. Flush pumping system with 1 to 2 gallons of clean water.
4. After each use, rinse tank with fresh water. Periodically inspect the recovery tank and decontaminate if necessary, using a Hospital Grade Virucide or a
10-1 bleach to water solution. Waste water should be disposed of properly.
Do not allow machine to freeze.
