In the USA this machine operates on a standard 15
amp 115 volt 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 breakdown, 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.
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 ra ccordement 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. Utilisez-le
uniquement sur des réceptacles protégés GFCI.
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug illustrated in Figure A. A temporary adapter looks like
adapter illustrated in Figures B and C, may be used to
connect this plug to a 2-pole receptacle as shown in
Figure B if a properly grounded outlet is not available.
The temporary adapter should be used only until a
properly grounded outlet (Figure A) can be installed by
a qualified electrician. The green colored rigid ear, lug
or the like 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
NOTE: In Canada, the use of a temporary adap te r is
not permitted by the Canadian Electrical Code.

HIL56087 - Operators Manual - Trident EX20
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 extractor. This
will prevent build-up of alkaline residue in the system. If
spray jets become clogged, remove the spray tips,
wash them thoroughly, and blow dry.
NOTE: Do not use pins, wire, etc. to clean nozzles as
this could destroy spray pattern.
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. Because the electrical cable
must be well insulated and cable connector screw kept
tight. If the cable insulation is broken or frayed, repair or
replace it immediately. Don't take chances with electrical fire or shock.
Maintenance
Daily / Regular Maintenance
Before making any adjustments or repairs to the
machine, disconnect the power cord from the electrical
source.
1. Empty unused cleaning solution from the solution
tank.
2. Inspect and clean filter screen in solution tank.
3. Flush pumping system with 4 or 7 liters of clean,
hot 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
1-10 bleach to water solution. Waste water should
be disposed of properly.
5. Check for and remove any lint or debris around vac
shoe.
6. Check spray jets for full spray pattern.
7. Remove lint and dirt build-up from brush an d
housing.
NOTE: Always store machine with brush in "Store"
position.
