•The Model BEXT®-100, 100H, 150H or 300HV is an extractor for cleaning carpet. When used with a floor tool, the

machine applies cleaning solution to the carpet and removes the dirty solution and soil from the carpet.

•Theextractorhascontrolstostartthepumpforthesolutionandthemotorforthevacuum. Thefloortoolshavecontrols

to release the solution.

•The extractor has a bypass pump. The pump runs when switched on, bypassing solution internally to keep pressure

even.The extractor starts when the solution lever on the floor tool is activated.

NOTE: Whenusingthe extractor tocleancarpets,followthis procedure:

1. Do not walk on freshly cleaned carpets for at least four hours or until the carpet is dry to touch.

2. Donot removealuminumorplastic piecesthathavebeen placed underthelegs of furnitureuntil

the carpet is dry.

3. Do not allow children or pets to crawl or walk around on the damp carpet.

4. Vacuum right after the carpet is dry and then vacuum the carpet once a week as needed.

INTRODUCTIONandMACHINESPECIFICATIONS

INSPECTION:CarfefullyunpackandinspectyournewExtractorforshippingdamage. Eachunitistestedandinspected

before shipment. Any damage incurred is the responsibility of the carrier, who should be notified immediately.

CLEANING SOLUTIONS: We recommend liquid cleaning chemicals. A pH of 7-9 is strongly recommended to avoid

premature pump wear, which would voide the warranty.

Topreparethe machineforoperation,followthisproce-

dure:1. Connect the vacuum hose to the hose connector

on the extractor and to the end of the vacuum tube

on the floor tool. See Figure 1 D, E

2. Connect the solution hose to the extractor and the

floor tool. To fasten the quick disconnect fitting,

slide the knurled collar on the female coupling

away from the opening. Push the male coupling

into the female coupling. See figure 3 A & B

WARNING: Do not use water that is hotter than

120°F (48°C).

3. Before moving the extractor onto the carpet, put

clean hot water into the solution tank.

4. Add a cleaning chemical, such as Clarkare®Ex-

tractor Concentrate, to the hot water. For the

correctamount, followthe directionsshown onthe

container.

Set-Up

WARNING: We recommend that you use liquid

cleaningchemicals. Powdercandam-

age machine. Powders can cause

build-up in the lines, heater, pump,

quick disconnects, etc., all of which

would void the warranty on those

items. A pH of 7-9 is strongly recom-

mendedtoavoiddamageandprema-

ture wear to the pump, which would

void the warranty.

Fill the holding tank with clear water and the detergent of

your choice. Mix well. Although this machine is designed

tosupplyinstant hotwater,theadditionofwarmorhotwater

to the holding tank is beneficial and will reduce pre-heat

times.

A. Plug in cord #1 (vac and pump), identified by the red "H"

on the end of the cord. Attach the priming hose to the

machine(on300HVonly). Turnthepumponandsetthe

switch to the upholstery setting. Run until the pump is

fullyprimed,thenturnoffthepump. Removethepriming

hose and attach the cleaning hoses and tool.

B. Turn on the pump and spray through the cleaning tool

for a few seconds to fill the lines with solution.

BEXT®100H, 150H & 300HV

C. Plug in cord #2. The "Locator" light will illuminate when

the cords are plugged into separate circuits. Turn the

"Heat" switch on; wait two minutes for the heat ex-

changer to reach operating temperature. You may now

begin cleaning. It will take about 10 seconds for the

initial heat to reach the wand. The "Mode" light will turn

on when the heat exchanger is actively heating. (See

Figures 5, 6 and 7)

NOTE:Ifthe"Locator"indicatorlightdoesnotilluminate

when cord #2 is plugged in, then both cords are on the

same line. Try other outlets until the light comes on.

CAUTION: If both cords are plugged into the

samecircuitbreaker,thebreakermay

blow when operating with the heater

on.

5. If the extractor removes an excess amount of foam

from the carpet, add a de-foamer such as Clarkare®

De-foamer Concentrate to the recovery tank. The

amount needed will vary according to the amount of

detergent already in the carpet.

CAUTION: Topreventdamage,useawater-basedde-

foamer ratherthananoil-basedde-foamer.

CAUTION: Donot leavetheextractororothercleaning

machines or tools on the carpet when not

inuse. Cleaning solution in the machines

and tools can leak onto the carpet and

cause light spots or stains.

NOTE: To order Clarkare®Extractor Concentrate, order

part no. 398421. To order Clarkare®Defoamer,

order part no. 398420.

INSTRUCTIONSFORCONNECTIONTOTHE

POWERSUPPLYANDELECTRICALGROUND- 120V

CAUTION: This machine will operate only on an

AC frequency and on the specified

electrical voltage shown on the name-

plate. Make sure you have the cor-

rect frequency and voltage before

connecting the power cord to an out-

let.

Thismachine mustbe connectedtoan electricallygrounded

circuit in order to protect the operator from electric shock.

This machine has an approved power cord with three

conductors as well as a plug with three terminals. Connect

the plug to a three holed receptacle. For maximum

protection against electric shock, use a circuit that is

protected by a ground fault circuit interrupter.

This machine uses a 120 volt AC 50/60 cycle electrical

circuit. Make sure you have the correct frequency and

voltage before connecting the power cord to an outlet. The

machine has a plug as shown in Figure 7. If a receptacle

connected to the electrical ground as shown in Figure 7 is

not available, contact an electrical contractor. Do not use

an adapter.

WARNING: To prevent possible electric shock,

protect the machine from rain. Keep

the machine in a dry building.

WARNING: To prevent possible electric shock,

always use a 3-wire electrical system

connected to the electrical ground.

For maximum protection against elec-

trical shock, use a circuit that is pro-

tected by a ground fault circuit inter-

rupter. Consult your electrical con-

tractor.

WARNING: Do not cut, remove, or break the

ground pin. If the outlet does not fit

the plug, consult your electrical con-

tractor.

WARNING: If the cords or plugs are worn or

damaged in any way, have them

replaced by an authorized service

person.

Extension Cords

Useonlyan approved extensioncordwith three conductors,

a plug with three terminals and a three-holed connector

body. This machine has a power cord with a wire size of 12

AWG. (AWG stands for American Wire Gauge).

CAUTION: If you use an extension cord, use one

that has a minimum wire size of 12

AWG. Be sure your extension cord is

no longer than 50 ft. Do not join two

extension cords.
