A. SIDE DOOR: Most installations are side door. This providw roar
access for accessories and hoses as well as unobstructed access to
componenffworking side of machine, thus making it a bit easier to
perform maintenance and/or repair without removing unit from the
truck.
B. REAR DOOR: Although this location partly limits working access, it does direct the noise away from the cleaning site. Some
cleaners in the colder areas prefer this location because it puts the
weight mass over the rear wheels for better traction in ice and snow.
Rear mounting requires the unit to be slid to the right side as far as
possible. This not only provides adequate working space on tlm
component side of the unit but also makes better weight distribution
inside the van (engine and component weight line up over drive
shaft). Also, it is physically easier to load unit into
height of van bed.

HARD WATER AREA MAP
The quality of water varies greatly throughout the United States and
influences the reliability and efficiency of equipment in direct proportion to its level of hardness. The map below defines areas which
compromise fluid related components such as hoses, fittings, heaters, pumps, valves and water cooled engines.
Cleaning efficiency and equipment life is increased, chemical use
decreased and the appearance of cleaned carpets enhanced when
water softeners are incorporated in hard water areas. Manufacturer
strongly urges the use of water softener units in areas exceeding 3%
grains per
quality ofwater inyour area and take action immediately should it be
necessary.

If the wand is spraying, the water will then flow to the heater. This

This systam has been designed to be the most simple and trouble-

This incoming water flows directly tothe mix tank. Water will nowflow
through a pmpcwtioning valve which will simultaneously mix the
chemical to achiew your desired solution. The mix tank isequipped
with 2 different float valves, one of which responds to the water level
af the tank and will maintain the proper volume of solution to be re-
swwed for the cat pump. The secondary float valve is a safety valve
that is desigmsd to protect your system from sudden or unexpected
loss of water supply. if, for example, the water source at the house
was turned off, the water level of the mix tank would drop, activating
the secondary valve which automatically kills the engine.

As you remove your discharge manifold, there isa set of 3 check valves (which usually fall out during dis-assembly). If the surfaces of
these check valves are dirty, or show signs of chemical build-up, it is
probable that they would remain open causing pressure loss or pul-
sation. Upon inspecting the valves, make sure that the teflon buttons
in the valve spring retainers are still itact. Also examine the discharge manifold. Look for problems such as cracks, chemical buildup or warpage due to freezing. Ifthis discharge manifold iswarped, it
will cause the check valves to stick and will result in lossofpressure.
The Cat pump cups are often the source of pressure loss. Upon inspection they may appear melted or torn, but often they will look
good. Replace them anyway. There is no sure method ofvisually in-
specting the cups. Hydra-Master recommends changing cups
whether they look good or not.
Anytime your’pump is being dismantled, Hydra-Master recommends
replacement of all ‘o’ rings and seals. This is merely a convenience
to the customer to make sure that the Cat pump is in top operating
condition.
The prrrm-a-lube seals located within the intake manifold will allow
air to enter the pump if they are worn. Again, it is difficult to visually
pinpoint a defective prrrm-a-lube seal. Replace them all.
Within the piston sleeve cylinders there are 6 ‘o’ rings that are about
‘/4 the size of a penny. If these ‘o’ ringsare bad, water will be pumped
back into the oil. If this has occured the oil will raise in level and will
appear milky. If you are unable to repair seals rightaway, change oil
e
frequently. Repair the pump as soon as possible so as to not dam-
age bearing or connecting rods.
Repairing of Cat pumps isnota difficulttask. However, before disassembling make sure you have the proper parts required.
1- short (or hot) cup kit
6- piston sleeve ‘o’ rings
3- Prrrm-a-lube seals
1- bottle Cat oil
Read instructions thoroughly, supplied in the Cat pump manual,
prior to disassembly and follow directions as stated. Oil all seals
thoroughly prior to installation. (Remember, a newly scarred seal is
no better than one you just took out.)

HIGH PRESSURE PUMP
TROUBLESHOOTING
A pump instruction brochure on pages 8-15 may assist you in resolving a pump related problem.
Plmmmvl:
o LOSS OF PRESSURE
CAUSE AND/OR SOLUTION:
1. Clogged Filter Screen in garden hose quick connect
coupler.
A. Remove and clean or replace filter.
2. Low water pressure at source.
A. Determine rate of flow and select an alternate source of
supply if water pressure is inadequate.
3. Defective or blocked check valves in high pressure pump
cylinder head.
A. Ok-assemble cylinder head and replace or clean applicable
check valve.
4. Delaminated, kinked or clogged hose between the mix tank
and the high pressure pump.
A. Remove and replace defective hose.
5. Defective pressure relief valve or debris in pressure relief
valve. NOTE: the high pressure bypass valve is designed to
fully close when the cleaning tool is turned on. Any foreign
matter collecting on the piston will prevent full closure of the
valve and allow a potilon of the water to continue to circulate
instead of being routed to the cleaning tool. To correct this
situation, the bypass valve must be disassembled and cleaned
(refer to drawing provided in this manual for bypass disassembly).
A. Disassemble and clean pressure relief valve as illustrated in
drawing.
B. Replace defective or worn out bypass cup.
C. Replace bypass valve.
6. Defective or worn cups.
A. Remove and replace piston cups as defined by pump manual.
7’.Loose drive belt for high pressure pump.
A. Readjust belt as required or replace if defective.
WATER FLOW
1. Worn out spray jet. NOTE: Cleaning tools designed to spray a
constant flow of 1‘/2GPM will average 1 gallon of flow per minute in
actual working situations since flow is not continuous. An average
flow of 1 GPM results in 6000 gallons of flow for every 100 hours of
unit operation. Spray tips are capable of consistent flow rates for
approximately 20,000 gallons. They should be replaced therefore,
approximately every 350 hours. Worn spray jets allow a greater
average rate of flow thus reducing desired temperature levels.
A. Remove and replace spray jet.

HEATIN
INFOR
The propane heater incoporatad in this equipment is of special d@sign for use in the carpet cleaning industry. [t’s high pressure coils
and thermostatic temperature control make it simple to operate and
reliable. One@tlw desired temperature is set, the heater’ will then go
‘on’and ‘off according tothe water temperature within the heater. As
water is used through the cleaning tool, cold water entering tlw heater will ati]vate the thermostatically controlled
firing the heater to maintain a consistent fiow of hot water. One@tho
cleaning wand is shut off and the flow of water through the heatfw
stops, the heater will continue to burn until the set tempimatwe is at-
tained.
It ispossible th~n with this design that the flame maybe on when tlm
wand is off, likewise, it is possible the flame may be off when the
wand is on.
~This beater is desicmed to burn warm mopane
gas only. Any liquid propane entering tke heater may c~use damage
to the control valve on the heater. Itwill also
and a soot build-upon the coils. Therefore, itis necessary to shut off
the heater and close the valve at the tank bfftween cleaning locations. Failure to do this allows sloshing liquid to enter
line to the heater.

cause many problems. To avoid
stop filling when whke liquid starts spurting from the 107. valve. To
prevent damage to the propane regulator, always close the valve on
the tank before filling.
When venting the heater through the roof of the van, it is necessary
to install a draft diverter on top of the heater. This will prevent down
drafts from blowing out the pilot light.
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 (see figure A
#6). To prevent road dust and moisture from entering the propane
regulator, keep the white Tupperware cover (supplied) on the regulator at all times.
To avoid restriction of airflowat 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 soot build-up.
IMPORTANT: If a 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. Should this condi-
tion exist, operator must depress the pilot buttonfor 1-5 minutes and
attempt to ignite the pilot light at 15 second intervals. A very slight
hissing noise should be evident while performing this operation.
HEATER- OPERATING
INSTRUCTIONS

A. TO START PILOT:
1. Adjust thermostat control knob on unitrolto ‘normal’. @ Fig. A.
2. Adjust upper dial to ‘pilot’position. @Fig. A.
3. Depress pilot button. @Fig. A.
4. While pilot button is depressed with the left hand, use
your right hand forefinger to depress the electric spark pilot
igniter button several times in rapid succession, then look to
see if pilot is lit. If not, depress in rapid succession again until
lit. If this fails, use the resourceful match.
NOTE: Whenever ignitingpilot, hold litmatch in front of pilotsight
opening before inspection. Move lit match toward pilot
burner. The pilot should ignite.
IF HEATER FAILS TO LIGHT:
Is propane tank full?
Is propane tank valve open?
Has air been properly bled from propane line?
Once pilot is litcontinue depressing button for 10 seconds to
insure thermo coupler has been heated.
B. TO LIGHT MAIN BURNER:
1. Turn upper knob to ‘on’ position. Flame will come on.
IF NOT: Pilot has expired.
Turn upper dial to ‘off position. @Fig. A.
Do not attempt to relight pilot for 60 seconds.
Then repeat instructions A -#1 -4.
Water may already beat controlled temperature.
IF YES: Flame will turn off when thermostat senses maximum temp.
C. TO ACHIEVEPROPER CARPET CLEANING
TEMPERATURE:
1. Complete procedures A & B
2. With 100’ of hose, turn cleaning wand on for 5 minutes and
the temperature should stabilize.
3. Once a constant temperature is established, turn cleaning
wand ‘off. The flame on the heater burner should remain on
for 10-15 seconds.
A. If the flame expires priorto 10 seconds, turn the
thermostat dial to a higher reading, then repeat C 1-3.
B. If the flame remains lit after 15 seconds, turn the

3. Overfilled propane tank. NOTE: Propane heater is designed to
operate on vapor propane only. Over-filling a propane tank
allows liquid propane to enter all heater related components
and permits an over-rich burning condition to occur. This
condition usually requires the heater core to be cleaned of soot
and carbon deposits. Cleaning is a messy, dirty job and very
inconvenient, so don’t let it happen to you!

DO NOT RUN ENGINE AT EXCESSWE SPEEDS. Operating an engine at excessive weeds increases the hazard of personal injury.
DO NOT TAMPER WITH PARTS WHICH MAY INCREASE THE GOVERNED SPEED.
For rotary Iawnmower safety, A. N.S. I. Standard Safety Specifications for power Lawn Mowers specify a maximum blade tip speed of
19,000 feet per minute (96.5 meters per second), primarily to reduce the hazard from thrown objects.
Rotary Iawnmower manufacturers select the governed top speed of the en9ine based on the length and design of the cutter blade and
desbgn of other mower parts.
All rotary Iawnmowers should be checked for conformance to the A. N.S. I. Standard Safety Specifications for Power Lawn Mowers on
blade tip speed, if the engine is repaired or replaced, or if mower parts are changed.
DANGER: GASOLINE VAPOR IS HIGHLY FLAMMABLE. Refuel outdoors preferably, or only in well ventilated areas.
DO NOT STORE, SPILL OR USE GASOLINE NEAR AN OPEN FLAME or devices such as

INFORMATION
There are two ways of positioning the machine in the truck as shown
on the following page. There are also two locations for the vacuum
recovey tank to be positioned. First, the standard way with the tank
directly alongside the machine. Second, with the tank across the
back ofthe machine as shown below; this location is most space efficient.

WATER SOFTENER
Many areas of the country have an excess of minerals in the water
which results inwhat iscommonly called “hard water”. These miner-
als tend to whsre to the insides d heater coils and other parts ofthe

The relatively law cost of a water softener service is more than made
up for in the increased life of machine parts and continued cleaning
efficiency. The water sofkmer will also increase the effectiveness of
the cleaning chemical being used, therefore, less chemical will be
needed.

to change the water softener in accordance with the capability of the
sdhwkw. Example: If the softener will treat 900 gallons of water and
the machines uses an average of 30 gallons per hour of use, and an
average of 5 hours a day, would be 150 gallons a day. 5 days would
equal 7!30 gallons ofwater, therefore, th@softener would be changed
every Gworking days for maximum softening.

OVER-WETTING
Over-wetting is annoying to all concerned and sometimes leaves a
bad impression of the cleaning process used.
There are several areas that will cause over-wetting:
1. Too few vacuum strokes or improper sawtooth vacuum
strokes as shown above.
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.

OVERALL CARE OF UNIT
MAINTAINING THE ORIGINAL APPEARANCE OF YOUR UNIT IS
IMPORTANT FOR TWO REASONS:
1. It represents a big dollar investment for your cleaning business
and its appearance should reflect that fact. A dirty machine is not
professional!
2. Maintenance, troubleshooting, and repair is much easier to
accomplish on a clean well maintained unit. Regular cleaning of
the machine offers you an opportunity to visually inspect allfacets
of the machine and spot potential problems before they occur.
FOLLOWING MAINTENANCE IS RECOMMENDED BY THE MANUFACTURER AT THE FREQUENCY INDICATED.
AFTER EACH JOB: Check recovey tank, s/s filter and filter bag as
required.
DAILY: Wipe machine down thoroughly with a damp cloth; flush recovery tank out thoroughly. Empty filter bag and inspect for rips,
tears, etc. - replace as needed; remove, thoroughly clean and
reinstall stainless steel filter screen in recovery tank; inspect and
clean vacuum slot on cleaning wand; check wand head for sharp
edges that could tear carpet - file down as needed; clean wand with
stainless steel cleaning compound to maintain original appearance
(available through grocery stores); wipe down vacuum and high
pressure hoses as needed - visually inspect for cuts, etc..
WEEKLY: Wipe down entire unit as needed - apply good coat of
auto wax to all painted surfaces inside and out, and to control panel;
thoroughly clean recovery tank using high pressure hot water (unit
with optional high pressure cleaning gun may be used for this); re-
move stainless steel filter in recovery tank, thoroughly clean remov-
ing all lint build-up, inspect for damage and reinstall. Remove filter
bag, thoroughly clean and reinstall - iftorn, replace; empty chemical
from chemical container, wash out thoroughly to remove any chemi-
cal build-up; inspect chemical feed line strainer and use 50% white
vinegar/water solution to remove any chemical build-up; thoroughly
clean wand and inspect for clogged jet, debris in vacuum slot and
leaking fittings at valve. Apply light coat of auto wax to wand;
thoroughly clean vacuum and high pressure hoses including hose
cuffs - inspect for wear or damage to hoses and quick connect fit-
tings. Inspect garden hose connect/adapter screen for debris, re-
move and clean thoroughly. Inspect all propane and gas lines for
wear or abrasions that may cause possible fuel leaks.
