HOW THE SYSTEM WORKS

The water system takes incoming water at tap (low) pressure, combines it
wilh chemicals from the chemical system and pumps it under pressure
through theheatingsystern, anctouttothec]eaning tool.After being sprayed
into the carpet, Ihe water/chemicaf/soil solution isextracted by the vacuum

system and returrwd to the waste recovery tank.

TRUCK SELECTION

The preferable vtllclefor HydraCat iristallationis apam?lvanwith aheavy­duty swyx?nsirm package. The capacity ofIho van should be a heavy-duty

1/2 ton at ttm minimum and more preferably a 3/4 ton o&pacity.

TRUCK PREPARATION

The manufacmrarmmmmands theinslallation ofpl~od flooring covered
wiftr paly propylene backed astroturf (do not use rubber-backed) in the
vehicl~ prior to installation of machine. This provides a metal to cushion
mounting rather than metal to metal, provides insulation and makes an
attractive van interior. Aslroturf should be color keyed to van interior.

Materials Needed:

1.2 sheets 4x8x5/fY exterior plywood

2. &xl 2’ piwe of commercial astrotwf

3. 16-f lM sheet metal screws

4.1 quart marine adhesive (optional)

5.1 staple hammar wII12” staples
(See illustration for correct placement of plywood flooring)

ILACEMENT OF UNIT
4VEHICLE

we are two recommended unit placements:

SIDE DOOR: Most installations are side door. This provides rearamss
p accessories and hoses as well as unobstructed access to compmwnti
]rfdngside of machirw, thus making it abiteasiw’ io perform maintenance
IWorrepair without removing unit from the truck.

REARDOOf%Afthaugh this location partly limits working access, itdoes
wet the noise away from the cleaning site. Some cleaners in the colder
eas prefer this location because if puts the weight mass ow?rthe rear
~eelsfor better traction in ice and snow. Rear mounting requires ttw unit

beslid tothe right side as faras possible. This not only provides adequate
xking space on the component side of the unit but also makes better
sight distribution inside the van (engine and cornponer?tweight line up
~erdrive shaft). Also, it is physically easier to load unit into rear door due

height of van bed.

WATER SOFTENER

Many areas of the country have an excess of minerals in the water which
results in what is commonly called “hard water”. These minerals tend to
adhere tothe insides ofheater coils andotherpartsof themachines causing
damage and a loss of cleaning effectiveness.

Reports from several of our machine users commending the results of the
useofwater softeners inconjunctionwith their machines prompts usto rec­ommend the procedure to everyone ina “hard water” area.

The relatively lowcost of awater softener service is more than made upfor
inthe increased Iifeof machine parts andcontinuedcleaning efficiency. The
water softener will also increase fhe effectiveness of thecleaning chemical
being used, therefore, less chemical will be needed.

Contactawatersoftener distributor inyour area forinformationon therental
ofa simple water treatment unit to carry in your truck. Be sure tochange the
water softener in accordance with the capability of the softener. Example:

Ifthe softener will treat 900 gallons ofwater and machines uses anaverage
of30gallons perhourof use,andanaverageof 5 hours aday, wouidbe 150
gallons a day. 5 days would equal 750 gallons of water, therefore, the

softener would be changed every 6working days for maximum softening.

Any frw~zing of this machine is not covefied by warranty and during the
~ldelrmantisofo~mtion, careful protection should be of utmost

THE FQLLWW4G PRECAUTIONS ARE RECOMMENDED:

1.Run machine befcm leaving for the first job to insure nothing
ha night lmfore, including hoses and wand.

2. Insulak the gafidt?nhose from the cold ground by running it through an

extra 1 1/2 inch vacuum hose.

3. In colder dirnates, insulating the truck walls and floorboards will help

prutoct the unit.

4, Don’tprocrastinate during thec!eaning operation or the hotwater solution

line will alw freeze an the ground. The solution iine should be insulated

in exlrerrmly cold climates.

!$.Whenever ~ssible, the truck and machine should be stored in a heated

garage at night or over the weekend. If not possible, place a 1500 watt

electric heater inside the truck, aimed directly at the machine. Never use

a propane heater-it causes excessive moisture on the truck ceiling and
the possibility of it going out is higher. Ifthe machine and truck are left
outside with a heater, you should first drain of possible water from the

machine cleaning tools and hoses. (They freeze also.)

TO DRAIN THE MACHINE FOLLOW THESE STEPS

1. Siphon a50150 mixture of anti-freeze and water through the chemical
ftow meter.

2. Drain the mix tank.

3. Connect Ma freeze

4.Connect Ihecdher ond of the freeze guard fitting tothe freeze guard fitting
Iocatfid on the sido of the machine.

5. Connect an open 440 quick connect to the fittings marked “cleaning
solution” on the front oithe machine. (An alternative would be to connect

your solution hww and wand, w as to freeze guard them also. Ifyou

choose to do thisycw will also need tohold the!riggerdown onthe wand.)

6. Start the unit, allowing the vacuum from the machine to drain the lines.

7.* Remove tfre garden hose inlet adapter from the end ofthe garden hose.
Conrmct the adapter to the incoming water quick connect on the front of
9hemachine.

8.’ Place a vacuum hose over the garden hose quick connect and allow the
vacuum from the machine to drain the lines.

*i4n alternative to #7 & 8 would be lo make an adapter to allow you to us@

the premade freeze guard hose.

CLEANING AND CHEMICAL
PRECAUTIONS

Yourmobile carpet cleaning plant has been engineered using the!at@stand
nest sophisticated technology available, to produce the finest carp@t
~eaning results possible. Despite this, however, itremains onlya toolofthe
xpet cleaning trade, and it can produce only as good a job as Me person
]Perating it.

Thereare not short cuts to good ca~t cleaning. Itrequirws time, cleaning
mowledge and the use of good chemicals.

Themanufacturer recommends the use of spotting agents, and traffic lane
nleaners prior to the actual cleaning of carpeting, as required.

Theuse of some chemicals through your mobile carpet cleaning plant can
seriously damage the internal plumbing, high pressure pump and heater.
(Chemical such as concentrated acids, solvents, and some paint oil and
grease removers w/high cwwentration of solvents.)

The manufacturer recommends only the use of chemicals containing rust
and corrosion inhibitors and water softening agents to prevent chemical
build-up which may lead to component failure and warranty invalidation.

NOTE: At no time should a chemical solution with a pH of less than 7 or
higher than 10 be used in the unit.

WATER AND CHEMICAL FLOW
OPERATION

This electro-mechanical system has been designed to be simple and
trouble free. Incoming water flows first through the Solenoid Control Valve
(1)and the low pressure Chemical Injector (2)which are both mounted on
the exterior of the mix tank. As the water passes through the Chemical
Injector, it is automatically proportioned with a predetermined quantity of
detergent. The MixTank(3)isequippedwith twodifferent float switches, the
Water Level Float (4) responds to the level in the tank and will maintain the
proper volume of solution to be reserved for the water pump. The secon­dary, LowWater Float switch(5) isasafetyswitch thatisdesignedto protect
your system from sudden or unexpected loss of water supply. If, for
example, thewater source at the house were turned off, the water level of
the mix tank would drop, activating the secondary switch, which automati­callydisengages thesystem and pn?ventsthewater pump from running dry.

The desired chemical injection ratio may be obtained by an adjustment of
the Chemical Flow Meter (6)during the fill cycle ofthe mix tank. Water must
beflowing into themixtankinorderto adjustthechemical mix. Thechemical
will flow from the Chemical Jug (7) to the Chemical Flow Meter, then to the
Chemical Injector where it is proportioned into the Mix Tank at the desired
chemical setting.

NOTE: %Mththisuniquechemical system, thechemicalflow isproportioned
only during the filling cycles of the MIXTank, not during the direct spraying
ofthewand. Therefore, itispossible that asyour wand is spraying, you may
have no chemical flow. Also, the converse is true in that you may not be
spraying your wand, but if the mix tank is in a filling cycle, your Chemical
Flow Meter may be active at the desired flow rate.

The chemical proportioning system will mix chemical with water at a 1to30
ratiowhen the Flow Meter is set at 5 GPH, or a 1to 15 ratio when the Flow
Meter is set at 10 GPH.

Atthis point in the flow, solution (water with chemical) will now be siphoned
from the

bottom of the Mix Tank to the inlet of the Water Pump (8). When

the wand is not using solution by spraying, the solution will be bypassed
fromthe bottom ofthe brass Pressure Relief Valve(9), back to the MixTank.

When the wand is spraying, the solution continues its flow to the Water

Heater (10). The coils of this heater have a capacity of up to 2 gallons,
therefore it is extremely important that all air pockets are bled out of the
heater prior to initial start-up. This maybe achieved by running the water
system, without the heater on, for approximately 80 seconds.

CHEMICAL SYSTEM MAINTENANCE

The chemical lines may need to be flushed with vinegar periodically to

prevent abnormal chemical build-up. This flushing may be done by remov-

ing the clear plastic hose from the Chemical Jug and inserting it into a one
