HOW THE SYSTEMWORKS
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.

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

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.

THE FQLLWW4G PRECAUTIONS ARE RECOMMENDED:
1.Run machine befcm leaving for the first job to insure nothing

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

5. Connect an open 440 quick connect to the fittings marked “cleaning

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.

]Perating it.
Thereare not short cuts to good ca~tcleaning. 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 CHEMICALFLOW
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)isequippedwithtwodifferent 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.
CHEMICALSYSTEMMAINTENANCE
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
