Introduction
CDS 4.6
Section 1-1
his manual contains operating instructions as well as information required
T
for proper maintenance, adjustment and repair of this unit. Since the first
and most important part of repair work is the correct diagnosis of the problem,
component manual troubleshooting charts have been included for your convenience.
Unlike a garden tractor, lawn mower or cement mixer, all having one or two
functions to perform, the truckmounted carpet cleaning plant has many functions to perform simultaneously.
The engine has to run at a consistent RPM.
The vacuum has to pull air and dirty water back from cleaning site.
The water pump must provide a stable pressure at proper water flow
for cleaning.
The chemical has to be injected into the water stream at the right
concentration.
The heating system must provide a consistant water temperature.
The vacuum tank must store dirty water until drained.
As you can see, it is not just a turn-key operation with one thing to worry
about, Does it start?!

Precautions
lthough this unit has been factory adjusted, it may require additional ad
adjustments to achieve optimum performance, for instance altitude may
A
require carburetor adjustment and ambient temperatures may require heat control adjustment. When required, consult an authorized representative.
♦ CAUTION ♦
THROUGH-FLOOR DRILLING: Be cautious when drilling holes through the van
floor. Many vans have critical components mounted directly below the van
floor that could be damaged by a misplaced drill bit. (See Product Support
Bulletins 92102, 94062 and 94063 at the end of the manual.)
♦ CAUTION ♦
LEVEL OPERATION: During operation, van or trailer must be parked on level
ground not to exceed + or - 10 degrees. Failure to insure proper leveling may
prevent proper internal lubrication of engine, vacuum and/or high pressure components.
♦ WARNING ♦
MOVING PARTS: Never touch any part of the machine that is in motion.
Severe bodily injury may result.

♦ CAUTION ♦
ACID RINSE AGENTS: The increased demand for clear water rinsing results
in the need for special care when using these acid based chemicals in your
equipment. The negative side of these products is the corrosive effects the
acid can have on metals, including swivels, pumps, heat exchangers, etc.
HydraMasters ClearWater Rinse has been formulated to protect vital components. HydraMaster will not warranty parts that have been damaged from
using unprotected acid products that have obviously caused failures.
♦ CAUTION ♦
HARD WATER PROTECTION: Failure to take appropriate measures to prevent
scale build up can result in system failure and loss of warranty on affected
parts. Test the water in your immediate and surrounding areas with hard water
test strips. Assume all water obtained from wells is hard. If you are operating
in a Hard Water Area (3.5 grains or more per gallon), use a water softening
system.
♦ CAUTION ♦
FREEZE PROTECTION: There is often little warning before a cold spell. Therefore, not protecting this equipment from freezing will result in costly downtime. Placing an electric heater in the truck or parking the truck indoors will
help to insure against freezing, but should not be the primary method of freeze
protection.

System Overview
he HydraVan CDS machines are highly engineered cleaning plants designed
T
by HydraMaster Corporation. The system utilizes the most current
technology available in water heating and water recovery systems.
The water flow is as follows:
Water is fed into the machine under tap pressure. The water enters the
machine and is combined with cleaning solution as it enters the mix tank.
The cleaning solution is picked up from the mix tank by the high pressure
pump and pumped under pressure through the heating system and then
out to the cleaning tool.
After the water is applied to the carpet, it is recovered by the vacuum
system and carried back to the recovery tank.
As there is no guess work in the manufacture of these highly advanced cleaning plants, there must be none in preparing it to get the job done in the field. It
is the purpose of this manual to help you properly understand, maintain and
service your cleaning plant. Follow the directions carefully and you will be
rewarded with years of profitable, trouble-free operation.
It is imperative that no section be overlooked when preparing for operation of
this equipment.

Local Water Precautions
he quality of water varies greatly. Many areas have an excess of minerals
T
in the water which results in what is commonly called hard water. These
minerals tend to adhere to the insides of heater coils and other parts of the
machines causing damage and a loss of cleaning effectiveness. This influences
the reliability and efficiency of equipment in direct proportion to the level of
hardness.
HARD WATER ADVISORY
HydraMaster recognizes that any hard water deposits which might occur within
the water system of our truckmounts is a serious problem. The precision
technology of truckmount heat exchanger systems is intolerant of any foreign
material. Hard water deposits will ultimately decrease the performance of the
system and are expected to seriously lower the reliability of the machine.
To validate a machines warranty, HydraMaster requires that all machines operating in designated Hard Water Areas (3.5 grains or more per gallon) be fitted
with a water softening system or a properly installed magnetic-type de-scaler
must be used and maintained. Periodic de-scaling or acid-rinsing alone is not
adequate in these areas. HydraMaster does not recommend any particular type
or brand, however the relative effectiveness of some types of magnetic descalers or softeners may require additional periodic use of de-scaling agents.
HydraMaster also recommends, in the strongest possible terms, that machines
in all areas be fitted with a water softening system for improved operation and
reliability.
HydraMaster Corporation
CDS 4.6
10/20/99
Page 1-16 Clutch Drive System
HydraMaster has included five hard water test strips with your machine. These
can be used to test the water in your immediate and surrounding areas as they
can vary greatly. Assume all water obtained from wells is hard.
♦ CAUTION ♦
Failure to take appropriate measures to prevent scale build up can result in
system failure and loss of warranty on affected parts.
HARD WATER AREA MAP
The following map defines areas in the United States which compromise fluid
related components such as hoses, fittings, heaters, pumps, valves and water
cooled engines. For other countries, hard water area maps can be obtained
from geological societies.
WATER SOFTENER
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. The manufacturer strongly urges the use of
water softener units in areas exceeding 3½ grains per gallon. Failure to use a
water softener in these areas will invalidate the machines warranty. Using a
hard water area map as a reference, determine the quality of water in your area
and take action immediately, if necessary.
Reports from several of our machine users commending the results of the use
of water softeners in conjunction with 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 by
an increased life of machine parts, reduced chemical costs and continued cleaning
efficiency. The water softener will also increase the effectiveness of the cleaning chemicals, therefore less chemical will be needed.
10/20/99
HydraMaster Corporation
CDS 4.6
Clutch Drive System Page 1-17
Contact a water softener distributor in
your area for information on 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. For example:
If the softener will treat 900 gallons of
water and the machine uses an average of 30 gallons per hour, for an average of 5 hours a day, this equals 150
gallons per day. In 6 days the machine would use 900 gallons of water.
Therefore, the softener would need to be changed every 6 working days for
maximum softening.

WASTE WATER DISPOSAL ADVISORY
There are laws in most communities prohibiting the dumping of recovered gray
water from carpet cleaning in any place but a sanitary treatment system.
This cleaning rinse water, recovered into your units vacuum tank, contains
materials such as detergents. These must be processed before being safe for
streams, rivers and reservoirs.
IN ACCORDANCE WITH THE EPA, STATE AND LOCAL LAWS, DO NOT
DISPOSE OF WASTE WATER INTO GUTTERS, STORM DRAINS, STREAMS,
RESERVOIRS, ETC.
In most cases, an acceptable method of waste water disposal is to discharge
into a municipal sewage treatment system after first filtering out solid material
such as carpet fiber. Access to the sanitary system can be obtained through a
toilet, laundry drain, RV dump, etc. Permission should first be obtained from
any concerned party or agency. One disposal method which usually complies
HydraMaster Corporation
CDS 4.6
10/20/99
Page 1-18 Clutch Drive System
with the law is to accumulate the waste water and haul it to an appropriate
dump site. Another solution to the disposal problem is to equip yourself with an
Automatic Pump-Out System. These systems are designed to remove waste
water from the extractors recovery system and actively pump the water through
hoses to a suitable disposal drain. Properly designed, they will continuously
monitor the level of waste water and pump it out simultaneously to the cleaning operation. The hidden benefit of this process is that the technician does not
have to stop his cleaning to empty the recovery tank. HydraMaster makes an
A.P.O. System available which can be ordered with new equipment or installed
later.
The penalties for non-compliance can be serious. Always check local laws and
regulations to be sure you are in compliance.

Section 2-1
our mobile carpet cleaning plant has been engineered using the latest
Y
and most sophisticated technology available to produce the finest carpet
cleaning results possible. Despite this, however, it remains only a tool of the
carpet cleaning trade, and it can produce only as good a job as the person
operating it.
PRECAUTIONS
There are no short cuts to good carpet cleaning. It requires time, cleaning
knowledge and the use of good chemicals. Therefore, the manufacturer recommends the use of spotting agents and traffic lane cleaners, as required, prior
to the actual cleaning of carpeting.
The use of some chemicals through your mobile carpet cleaning plant can
seriously damage the internal plumbing, high pressure pump and heater.
These harmful chemicals include concentrated acid (see the pH chart at the
end of this section), solvents, and some paint, oil, and grease removers with
a high concentration 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.
♦ CAUTION ♦
The increased demand for clear water rinsing results in the need for special
care when using these acid based chemicals in your equipment. The negative
side of these products is the corrosive effects the acid can have on metals,
including swivels, pumps, heat exchangers, etc.
HydraMaster Corporation
10/20/99
Page 2-2 Clutch Drive System
HydraMasters ClearWater Rinse has been formulated to protect vital components. HydraMaster will not warranty parts that have been damaged from
using unprotected acid products that have obviously caused failures.
The use of detergents and chemicals which create foam when agitated should
be avoided. Foam passing through the blower could lead to serious problems.
HydraMaster and SafeClean chemicals are formulated with built in anti-foaming
agents. When cleaning surfaces with excessive foaming residue use HydraMaster Powder Defoam as directed.
CLEANING STROKE PROCEDURE
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 positive lock for the vacuum and minimize the hopping effect
resulting on carpet that is not smooth. During the forward and reverse strokes,
movement to the right or left should only be accomplished at the extreme rear
of the stroke. Overlapping is also important to ensure even application of
solution and prevent saturation when cleaning wand is stopped twice at the
same point at the rear of the cleaning stroke. This is illustrated at the end of
this section.
Failure to adopt this procedure can result in increased chance of clean streaks,
fiber shrinkage, brown-out and longer drying periods.

Clutch Drive System Page 2-3
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-wetting:
1. Too few vacuum strokes or improper saw-tooth vacuum strokes as shown
in the following illustration.
2. Obstructed, cut or kinked 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.)
