HOW THE SYSTEM WORKS

:HEM[CAL SYSTEM: Electro-mechanical, meter Conlro!l@d.

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 is extracted by the vacuum
system and returrwd to the waste recovery tank.

WATER: Propane fired, thermostatically controlled (180,000 BTU).

There is no guess wrk in the manufacture of these highly advanced
cleaning pfmts.There must also be no guess work in preparing it to get the
job done in the field. h is the purpose of this manual to help you prqwty
understand, maintain and service your cleaning pfant. Follow the directions
carefully and you will be rewarded with years of profitable trouble-free
operation.

TRUCK SELECTION
The preferable vtllclefor HydraCat iristallationis apam?l van with a heavyduty swyx?nsirm package. The capacity of Iho van should be a heavy-duty
1/2 ton at ttm minimum and more preferably a 3/4 ton o&pacity.

we are two recommended unit placements:
SIDE DOOR: Most installations are side door. This provides rearamss
paccessories and hoses as well as unobstructed access to compmwnti
]rfdng side of machirw, thus making it a bit easiw’ io perform maintenance
IWorrepair without removing unit from the truck.

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.

REAR DOOf%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?r the rear
~eels for better traction in ice and snow. Rear mounting requires ttw unit
be slid to the right side as far as 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.

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)

alsohighly recommends a flue be installed between the lop of the heate

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 to the insides of heater coils andotherpartsof the machines causing
damage and a loss of cleaning effectiveness.
Reports from several of our machine users commending the results of the
use of water softeners inconjunctionwith their machines prompts us to recommend the procedure to everyone in a “hard water” area.
The relatively low cost of a water softener service is more than made up for
in the increased Iifeof machine parts andcontinuedcleaning efficiency. The
water softener will also increase fhe effectiveness of the cleaning chemical
being used, therefore, less chemical will be needed.
Contactawatersoftener distributor in your area forinformationon the rental
of a simple water treatment unit to carry in your truck. Be sure to change the
water softener in accordance with the capability of the softener. Example:
Ifthe softener will treat 900 gallons of water and machines uses an average
of 30 gallons perhourof use, andanaverageof 5 hours a day, wouidbe 150
gallons a day. 5 days would equal 750 gallons of water, therefore, the
softener would be changed every 6 working days for maximum softening.

WASTEWATER DISPOSAL
ADVISORY
Them are laws inmost communities prohibiting the dumping of recovers
‘gray” water from carpet cleaning in any place but a sanitary treatmel
system.
This cleaning rinse water, reccwred into your unit%vacuum tank, contair
materials such as dete~ents, which must be procwed before being se
for streams, rivers and reservoirs.
IN ACCCMM2AMCE WITtf THE EPA, STATE AND LOCAL MWS, D
MM MWW$f OF WASTEWATER MK7 GUTTERS, ST0f?h4 DRAIN
STllEAA@ RESEJ?Vt’WS, ETC.
Inmost cases, anacoep!ab[e method of wastewaterdisposal is to discharf
into a municipal sewage treatment syst@m after first filtering out sol
material suctwmrrpetfiber. Access to the sanifwy system can be obtaim
through a toilet, laundry drain, carwash drain, RV dump, etc. Permissi[
should first be obtained from any concerned party or agency.
One dis~sal rmtfwd which usually complies with the law is to accumula
the wastewater and haul it to an appropriate dump site. Another solution
the disposal pmblam is !0 equip yourself with an Automatic Pump-O
System. Thetm systems afie designed 10 remove wastewater from tl
tixtractor’s rwoovery system and actively pump the water through hoses
a suitable disposal drain. Properfydesignecf, they will continuously monii
tie Iml of wasttwvaler and pump it out simultaneously to the cleanil
operalion. Tim hidden benefit of this procm is thatthe operator does
have to stop his cleaning to empty the recovery tank. HydraMaster mak
an A.P.O. System available which can be ordered with new equipment
installed Iat@r.

. Start engine (choke as required}. Engine is at operating speed (r@cam
mended -2600 RPM). Allow warm-uP period of 2-5 minutes.

NOTE: Hot cfbnate opw’ation [above 90°F].
When operating this unit in a hot climate, HydraMaster highly recommends
some additional precautions.
1. Operate with side and rear doors fully open.
2. Vent heater through the top of van.
3. If vapor lock conditions arise, machine cover may need to be raised to
allow additional heat to escape from canpwtmt?nt.
NOTE: Cold cfimate operation (below O°F).
When operating this unit in a cold weather application, HydraMaster highly
recommends some additional precautions.
1. If nossible carrv Your own fresh water SUDDI%
2. Hookup to ho~wkder source if possible to’keep your incoming garden
hose ~m freezing.
3. Do not close van doors in front of machine.
4. Be aware that solution lines laying on frozm ground may frewe.
5. Contact local propane dealer about cold weather propane use.

Thi?penalties for nwr+ompliance can be serious. Always check local la’
and n?gufaticms M be sum you are in compliance.

SHUT DOWN
1.Turn heater to ‘off”

position. Spray wand for at least 3 minutes to allow
the heater coils to cool.
2. Close valve on propane tank and through floor hookup.
3. Remove vacuum hose.
4. Flush clear water through chemical system for 10 seconds. (Vinegar
should be rinsed through system weekly.] Turnoff chemical flow meter.
5. Tumon cleaning tool to flush chemical from unit hoses and cleaning tool.
NOTE If freeze guard is necessary, perform steps 1 & 2 of freeze guard
procedure at tlls time.
6. At this time, the blower should be lubricated with Pennz@xwd.
7. Shut engine down.
8. Drain vacuum tank. Vacuum filter should @cleaned prior 10mobilization

CLEANING AND CHEMICAL
PRECAUTIONS

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

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, it remains onlya tool of the
xpet cleaning trade, and it can produce only as good a job as Me person
]Perating it.

THE FQLLWW4G PRECAUTIONS ARE RECOMMENDED:
1. Run machine befcm leaving for the first job to insure nothing has frozen
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’t procrastinate during thec!eaning operation or the hot water 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. If the machine and truck are left
outside with a heater, you should first drain of possible water from the

There are not short cuts to good ca~t cleaning. It requirws time, cleaning
mowledge and the use of good chemicals.
The manufacturer recommends the use of spotting agents, and traffic lane
nleaners prior to the actual cleaning of carpeting, as required.
The use 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.

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

TO DRAIN THE MACHINE FOLLOW THESE STEPS
1. Siphon a 50150 mixture of anti-freeze and water through the chemical
ftow meter.
2. Drain the mix tank.
3. Connect Ma freeze guardhow? to the rwxwery tank.
4. Connect Ihecdher ond of the freeze guard fitting to the 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. If you
choose to do thisycw will also need to hold the !riggerdown on the 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 of the 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.

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

CLEANING STROKE
PROCEDUREIOVER-WEUING
PIJRPOSE:TO eliminate excess moisture rernainirrg in the carpet fiber and
the sawtooth appearanw? which results from diagonal movement of the
cleaning tool on all types of carpet.

NQTE: Prior to freezo guarding your rnachinemake sure the heating system
has been cooled down.

ALTERNATE PROTECTION
ANTI-FREEZE:

pH CHART

PROCEDURE: Always move the cleaning tool in smooth foward anciMckward strokes. Apply slight pressureto the forward stroke while the solution
is injected into the carpet. When extracting (drying), apply firm pressure on
the foiward stroke to ensure a positive “lock” for the vacuum and minimize
the “hopping” effect resulting on unsmooth carpet. During the forward and
reverse strokes, movement to the right or left should only be a~omplishexi
at the extreme rear of the stroke. Overlapping is also important to ensure
even application of solution to prevent saturation when cleaning wand is
stopped twice at the same point at tie rear of the cleaning stroke.

USING

1. Follow We draining procedure.
2. Cmnect solution hoses and wand to machine.
3. Pour a 50/50 ariti-$reeze sokJtion into mix tank.
4. Turn on machine and engage clutch. Spray the wand.
5. Continue to add anti-freeze solution until mixture comes out of wand set.
6. Remove and store hoses.

Failure to adoot this mocedure can result in increased chance of “clean
streaks”, fiber’shrinkage, brown out, and longer drying pdods.
INCORRECT

If you are using an anti-freeze solution to protect your machine from
freezing. 1[is ne~ssary to flush the machine in preparation for use. Simply
connect the unit to fresh water and spray the wand until anti-freeze solution
is discharged. The anti-freeze soiution maybe recovered by spraying into
an empty container. This solution can be used several times.
