manual trothlwahootingcharts have been included for your convenierm.
HOW THE SYSTEMS WORK
THE BOBCAT SYSTEM WORKS AS FOLLOWS:
The water system takes incoming water at tap(!ow) pressure, automatically
combines it with chemicals from the chemical system, pumps it under
pressure tfmugh the heating syslern and out to the cleaning tcml. Afhw
being sprayed into the carp?~ the water/chemic-alhoilsolution is extfacted
by the vacuum system and returned to the wasJe recmrytank.
Unlike a gamf%ntracfur, lawn mower or~mentmixer, al! hating one or W
functions M perform, tha truck-mountedcarpet cleaning ptant has many
functions to pwform simuitaneouqy.
* Engine has to run at a consistent RPM.
‘ Vacuum has to pull air and dirty water baok from cleaning site.
* Waler pump provides stabte pressure at proper water flow for cleaning.
‘ Chemical has 10be injected into the water stream at the
right concentration.
* Heater must maintain proper heat.
*Vacuum tank must store dirty water until drained.

THE AQUACAT 3.5 SYSTEM WOHKS AS FOLLOWS:
The AquaCat 3.5 High Perlorrnance Heat Exchanger system is
engineered cleaning plant, designed by HydraMaster Corp. The system
utilizes a dynamic heating system comprised of two separate exhaust h@at
exchangers for capturing ‘free heat=.
Water is fed into the machine at tap pressure. It is combined automatically
with cleaning solution as it enters the mix tank. The solution is then picked
up by the high pressure pump and pressurized to the desired level. Th8
solution then travels to the bypass assembly where it is distributed out to ttw
wand and back into the machine. The solution going back into the machine
splits flow and travels through the two exhaust heat exchangers. NW’ being
heated, the solution returns to the mixtankwhereit is picked up by the pump
again.
When the cleaning solution reaches a pre-sat high terrqwature,it is
released from the system and directed to the recovery tank, then cool water
enters the system to regulate the temperature.

TRLICK PREPARATION
Th~ manufacture recommends the installation of plywood flooring covered
with poly propylene backed astroturf (do not use rubber-backed)in the
vehiclo 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. Astroturf should be color keyed to van interior.
Materials Needed:
1.2 sheets 4x8x9$* exterior plywood
2. 6x12’ piew of commwcial astroturf

MACHINE INSTALLATION
There are two locations to place the machine, in the side duor or in the real
door, as mentioned in the section titled “Placement of Unit.” The standara
way to configure the unit is, as shown in the illustration, with the recoveq
tank beside the unit. An alternative method, not shown, would be to put tfw
recovery tank behind the unit. (The standard machine does not come witt
enough hardware to allow for mounting of the tank behind the mactrhe. I
this configuration is chosen please contact HydraMaster for more infer
mation.)
HydraMaster recommends that the exhaust for the machine be P@
through the floor of the vehicle. It is important that the machine be placw
as cfose to the door as possible so that outside air can be pulled into tlw
engine for proper cooling.

HAM) WATER AREA MAP
The quality of vvatw varies greatly throughoutthe United States an{
influences the reliability and efficiency of equipment in direct proportion t{
its leve~of hardness. The map bdowdefinesareas which compromise flui(
related cwmfxmwms such as hoses, fittings, heaters, pumps, valves an~
water cooled engines.
Cleaning dficioncyand equipment life is increased, chemical use de
crwumd and the appearance cd cleaned carpets enhanced when wate
softeners are incaporatedin hard water areas. Manufacturerstrong!
urges the use of watr3r softener units in areas exceeding 3 1/2 grains pe
gallon. Using We legend as a reference, determine tie quality of water ii
your arm and tak~ action immediately should it be necessary.
INATEI?SOFTENER
dany areas of the country have an excess of minerals in the watw which
esults in what is commonly called ‘hard water”. These minerals t~nd to
idhere to the insides of heaterwils and other pans of the machines causing
!amage and a loss of cleaning effectiveness.
?e~rts from several of our machine usk+rscommending the rwx.dts of Me
Ise of water softeners in conjunction with their machines prompts us to
ecommencf the procedure to everyone in a “hard watw’” area.
~herelatively low crestof a water Wtener service is mor~ than made up for
nfhe increaw+d life of machine parts and continu@d deaningefficiemcy.The
vater softener will also increase the effectiveness of the cleaning chemical
wing used, therefore, less chemical will be needed.
;Ontact a water softener distributor in your area for information cmthe rental
]f a simple water treatment unit to carry in your truck. Be sure to change ttw
vater softener in accordance with the capability of the softener. Example:
fthe softener will treat 900 gal!ons of water and machines uses an average
}f30 gallons per hour of use, and an average of 5 hoursa day,woukf be 150
]allons a day. 5 days would equaf 750 gallons of water, therefore, the
;oftener would be changed every 6 working days for maximum softening.

This electro-mechanicalsystem has been designed to be simple and
trouble free. Incoming water flows first through the Solenoid Control Valve
(I)(seeillustrationon next page) andthelowpressureChemical injector(2)
which are both mounted on the extenorof the mix tank. As the water passes
through the Chemical Injector, it is automaticallyproponionedwith a
predetermined quantity of detergent. The Mix Tank(3) is equipped with two
different float switches, the Water Level Float (4) respmcfsto the !evel in the
tank and will maintain the proper volume of solution to be reserved for the
water pump. The secondary, Low Water Float switch (5) is a safety switch
that is designed to protect your system from sudden or unexpected loss of
water supply. If, for example, the waler source at the house were turned off,
the water level of the mix tank would drop, activating the secondary switch,
which automatically disengages the system and prevents the water pump
from running dry.
The desired chemical injection ratio may be obtained by an adjustment of
the Chemical Flow Meter (6) during flw fill cycle of the mix tank. Water must
be flowing into the mix lank inorderto adjust the chemical mix. The chemical
will flow from the Chemical Jug (7) to the Chemical F{ow Meter, then to the
Chemical Injector where it is Proportioned into the Mix Tank at the desired
chem”~l setting.
NOTE: With this unique chemical system, the chemical flow isproportioned
only during the filling cycles of the MIX Tank, not during the direct spraying
of the wand. Therefore, it is possible that as your wand is spraying, you may
have no chemical flow. Also, the converse is true in that you may not 1#
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 profmlioningsystem will mix chemical with water at a 1to 30
ratio when the Flow Meter is set at 5 GPH, or a 1 to 15 ratio when the Flow
Meter is set at 10 GPI-I.

Wfwn the wand is spraying, the solution continues its flow to the Water
HtMar (10). The coils of MS twaler have a capacity of up to 2 gallons,
therefore it is extremely important that all air pockets are bled out of the

AQUACAT WATER FLOW
At this point in the flow, solution (wakw with chemicat) will now be siphorwd
from the bottom of the Mix Tank to the inlet of the Water Pump (8). In ttw
pump the water is pressurized and then discharged through a rubber
pulsation hose down to Uiepressureretiefvalve (9). From tfwpressure relief

bypawdback to the mix tank, depending on water usage at tfw wand.
As the water travels back toward the mix tank from the Wessum relk?f vatve
it flows through M exhaust heat exchangers which heat the cleaning
water.
CHEMICAL SYSTEM MAINTENANCE
The chemical lines may need to be flushed with vinegar wriodiilyto
prevent abnormal chemical build-up. This flushing may be dom by removingthe clear pfastic hose from the Chemical Jug and inserting it into a one
quart cmtainer of ki’wgar. This should k done with the Chemical flow
Meter setting on 10 GPH and the Water Heater ‘off’. Simply spray water
from the wand until the quart of vinegar isexhausted, the repeat W pmc$ss

Check that hoses at the Mix Tank(3) are secure. Check that the hose from the top
of the Flow Meter (6)10 the Chemical Injector (2) is secure with no idnks or
leaks. Check that the adjusting cap on the
atllhe way in. Check the s/s chedr valve insidethe injeciorfor chemicatbuiidup and proper cperafkm. Chac+Ithe hose from the Mtom of the flow Meter

As you rwnove your dischargra manifold, there is a set of 3 check valves
(which usually fall out during dismantling]. If the sudaces of the%e check
valves am dirty, or show signs of chemical build-up, it is probable that they
would rwnainopen causing pressur~ loss orpu!sation. Upon inqwcting the
valves, make sure that the tef!on button in the valve spring retainers are still
intact. Also t?xarnine the discharge manifold. Look for problems such as
cracks, chwnical buildup or warping due ta freezing. If this discharge
manifold is warp@d, it will cauwl the check valves to stick and will result in
[0ss of pressure.
The Cat pump cups are often the source of pressure loss. I@m inspection
they may appear melted or torn, but often they will look good. Replam them
anyway. There isno sur’ernethodofvisuallyinspecting the cups. HydraMaster recommends changing cups whether they look good or not.

FUEL RECOMMENDATIONS
This engine will operate satisfactorily on any gasoline intended forautomo-
tive use. A minimum of 850ctane is recommended. OONOTiWXO/L
GASOLINE.
Use clean, fresh, lead-free gasoline. We recommend the use of f3riggs &
Stratton Gasoline Additive, part no. 5041. Purchase fuel in quantity that can
be used within 30 days. This will assure fuel freshness and volatility tailored
to Ihe season. Leaded gasoline maybe used if lead-free is not available.
Use of lead-free gasoline results in fewer combustion deposits and longer
valve life.
WITH
Carburetor Adjustment Screws
NOTE: We DO NOT recommend the use of gasoline which contains
alcohol, such as gasohol. However, if gasoline with alcohol is used, it
MUST NOT contain more than 10 percent Ethanol and MUST be
removed from the engine during storage. DO NOT use gasoline contain-
ing Methanol. See STORAGE INSTRUCTIONS(page 27).

To avoid misunderstandingswhich might
and authorized Briggs & Stratton service accounts, we are listing some of
the causes of engine failure, where repair or replacement is NOT covered
by Briggs & Stratton warranty.
NORMAL WEAR:
Warranty will not cover repair where normal use has exhausted the life of
apart or engine. Engines, like all mechanical devices, need periodic parts
replacement and service to perform welf. It should be remembered that the
service life of any engine is dependent on the care it receives and the
conditions under which it has to operate. Some applications, such as tillers,
trash pumps, rotary mowers, are very often used in dusty ordirtyconditions,
which can cause what appears to be premature wear. Such wear, when
caused by dirt, dust, spark plug cleaning grit or other abrasive material,
which has entered the engine because of improper maintenance, is not
covered by Warranty.
ABUSE OR NEGLECT:
1. Bent or broken crankshafts: Such damage isnormallythe resuitof abuse,
such as striking a solid object with the cutter bfade on a rotary fawn
mower, and is not covered by Warranty.
2. Engine repairs required from the use of contaminated or stale fuel are not
covered by Warranty. Such failures would include sticking valves, and
carburetors and fuel pipes which are clogged by gum deposits which
form through the use of stale fuel. Always use clean fresh
regular gasoline.
Parts which are scored or broken because an engine was operated

PRECAUTIONS
Your mobile carpet cleaning plant has been engineered using the latest ant
most sophisticatedtechnology available, to produce the finest carps
cleaning results possible. Despite this, however, it remains onlya tool of ttx
carpet cleaning trade, and it can produce only as good a job as the Persol
operating it.
There are not short cuts to good carpet cleaning. It requires time, cleaniry
knowledge and the use of good chemicals.
The manufacturer recommends the use of spotting agents, and traffic Ianf
cleaners prior to the actual cleaning of carpeting, as required.
The use of some chemicals through your mobile carpet cleaning plant
seriously damage the internal plumbing, high pressure pump and heate
(Chemical such as concentrated acids, solvents, and some paint oil anf
grease removers w/high concentration of solvents).
The manufacturer recommends only the use of chemicals containing rus
and corrosion inhibitors and water softening agents to prevent chemica
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 70
higher than 10 be used in the unit.
pH CHART
caI
OVER-WETTING
Over-wetting is annoying to all concerned and sometimes leaves a bad
impression of the cleaning process used.
THESE ARE SEVERAL AREAS THAT WILL CAUSE OVER-WEfTING:
1. Too few vacuum strokes or improper saw tooth vacuum strokes as
shown in the previous illustration.
2. Obstructed, kinked or cut hoses.
3. Vacuum tank drain valve left partially open.
4. Clogged vacuum blower filter or vacuum tank lid not sealing properly.
5. Cleaning a heavily foam-saturated carpet without defoamer. (We recommend crystal type.)
INFORMATION
The propane heater incorporated in this equipment is a spxial design for
use in the carpet cleaning industry. If’shigh pressure coils and thermostatic
temperature control make itsimple too~rateand reliable. Once the desired
temperature is set, the heaterwill then go ‘on’ and ‘off according tothe water
temperature within the heater. As water is used through the cleaning tool,
cold water entering the heater will activate the thermostatically controlled
propane valve thereby firing the heater to maintain a consistent flow of hot
water. Once the cleaning wand is shutoff and the flow of water through the
heater stops, the heater will continue to burn until the set temperature is
attained.
Itis possible with this design that the flame maybe on when the wand isoff,
likewise, it is possible the flame maybe off when the wand is on.

CLEANING STROKE
PROCEDURE/OVER-WETT’lNG.
PURPOSE:TO eliminate excess moisture remaining in the carpet fiber and
the sawtooth appearance which results from diagonal movement of the
cleaning tool on all types of carpet.
PROCEDURE:Always move the cleaning tool in smooth forward and
backward strokes. Apply slight pressure to the forward stroke while the
solution is injected into the carpet. When extracting (drying), apply firm
pressure on the forward stroke to ensure a pasifive “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
accomplishedat 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 the rear of the
cleaning stroke.
Failure to adopt this procedure can result in increased chance of “clean
streaks’, fiber shrinkage, brown out, and longer drying periods.

This heater is designed to burn vaporpropane gas only. Arryiiquidpropane
entering the heater may cause damage to the corrtro/ valve on the heater.
It will also cause improper bumihg and
a soot build-up on ttre coils.
Therefore, it is necessary to shut OHthe heater andc/ose the valw? at the
tank between cleaning locations. Fai/ure to do this allows sloshing liquid to
enter the vapor feed line to the heater.
fMPORTANT: Overfilling of the propane tank wilf cause many problems. To
avoid this, advise the attendant filling the tank not toffll the tank over 90%.
When filling the tank, watch tti 10% valve and immediately stop filling Men
white liquid starts spurtfng from the 10% valve. To prevent damage to the
propane regufator, always close the valve on the tank before filling.
The propane regulator is pre-set at the factory at 6 oz. of propane. This
reading is taken at the control valve on the heater. To prevent road dust and
moisture from entering the propane regulator, keep the white plastic cover
(supplied) on the regulator at all times.
To avoid restriction of air flow at base of heater, keep articles such as
chemical containers, hose, boxes, etc. from within 18 inches of base of
heater. NOTE: This restricted situation also creates an over rich condition
which results in wot build-up.
IMPORTANT: Ifa new propane tank has been installed or hoses have been
disconnected, air may enter propane hoses and must be purged prior to
attempting to light the pilot burner. Shoufdfhismnditionexist, operator must
depress the pilot button for 1-5 minutes and attempt to ignite the pilot light
at 15 second intervals. A very slight hissing noise should b evident while~
performing this operation.
Check heater forpopaneleaks reguladyas loading and unloading hoses,
