HOW IT OPERATES:
This machine is a portable, easy to use carpet extractor
designed for use indoors, in a household or light
industrial environment.
When operating as a carpet extractor, cleaning solution
is dispensed onto the carpet and agitated by a rotating
brush. The solution is then extracted from the carpet by
a vacuum. The head on the brush is floating, allowing it
to automatically adjust to various carpet depths while
applying an effective brush pressure.
1. To avoid electric shock use indoors only.
2. To reduce risk of fire, do not use volatile
substances.
3. Use only cleaners intended for carpet
application.
INSPECTION:
Carefully unpack and inspect your extractor for shipping
damage. Each unit is operated and thoroughly
inspected before shipping, and any damage is the
responsibility of the carrier, who should be notified
immediately.
ELECTRICAL:
This extractor operates on a standard 15 amp 120 volt
AC circuit. This is the typical wall receptacle found in
household and light industrial environments. Voltages
below 105 volts or above 125 volts could cause serious
damage to motors. *Special voltage models available. A
wiring diagram is mounted inside the rear control panel
of machine. A copy of the wiring diagram is included in
this Owner’s Guide.
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.
Improper connection of the equipment-grounding
conductor can result in 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 – I is will no fit the
outlet, have a proper outlet installed by a qualified
electrician.
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 adaptor that looks like the adaptor 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 adaptor 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 adaptor must
be
connected to a permanent ground such as a properly
grounded outlet box cover. Whenever the adaptor is
used, it must be held in place by a metal screw.
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: This extractor is equipped with a 25 ft. 16/3
power cord.
To avoid possible distortion of polyethylene
solution/recovery tanks, DO NOT USE WATER
TEMPERATURE THAT EXCEEDS 140 F (60 C).
