1-3: General Information
Warnings, Cautions and Notices
HydraMaster uses this WARNING symbol throughout the manual to warn of possible
injury or death.
This CAUTION symbol is used to warn of possible equipment damage.
This NOTICE symbol indicates that federal or state regulatory laws may apply, and also
emphasizes supplemental information.

General Information: 1-4
Warnings and Cautions specic to the CDS 4.8 / 4.6 include:
HOT SURFACES: During the operation of this equipment, many surfaces on the machine
will become very hot. When near the van for any reason care must be taken not to touch
any hot surface, such as the engine or the exhaust.
HEARING PROTECTION: The Occupational Safety and Health Administration (OSHA)
recommends the use of hearing protection when a technician is exposed to an average of
85 decibels (this is an average of exposure over an 8 hour period). This equipment can
produce 85 decibels to a distance of 10 feet. Please check with your local state agencies
to see if OSHA standards apply to your application.
NO SMOKING: It is unsafe to smoke in or around the vehicle. Do not allow any open
ames in or around the vehicle.
CARBON MONOXIDE: This unit generates toxic fumes. Position the vehicle so that the
fumes will be directed away from the job site. Do not park where exhaust fumes can enter
a building through open doors, windows, air conditioning units or kitchen fans.
TOXIC FUMES: Do not occupy the vehicle when the cleaning equipment is operating.
Toxic fumes may accumulate inside a stationary vehicle.
ENGINE EXHAUST: The engine exhaust from this product contains chemicals known to
the State of California to cause cancer, birth defects or other reproductive harm.
MOVING PARTS: Never touch any part of the machine that is in motion. Severe bodily
injury may result.

1-5: General Information
The use of some chemicals through your mobile carpet cleaning plant can seriously
damage the internal plumbing, high-pressure pump, chemical pump and heat exchangers.
These harmful chemicals include concentrated acid (see the pH chart in Figure 2-1),
solvents (including d-Limonene), and some paint, oil and grease removers with a high
concentration of solvents.
THROUGH-FLOOR DRILLING: Be cautious when drilling holes through the van oor.
Many vans have critical components mounted directly below the van oor that could be
damaged by a misplaced drill bit.
LEVEL OPERATION: During operation, the vehicle must be parked on level ground
not to exceed + or - 10 degrees. Failure to ensure proper leveling may prevent proper
internal lubrication of engine, vacuum and/or high pressure components.
ACID RINSE AGENTS: Some acid rinse products can cause damage to internal machine
components. Failure to take appropriate measures to prevent acidic corrosion can result
in system failure and loss of warranty on affected parts.
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 at 3.0 grains or more
per gallon, use a water softening system.
FREEZE PROTECTION: Failure to take appropriate measures to prevent equipment
damage due to freezing can result in system failure and loss of warranty on affected
parts. Placing an electric heater in the vehicle or parking the vehicle indoors will help
ensure against freezing, but should not be the primary method of freeze protection.

1-9: General Information
Local Water Precautions
The quality of water varies greatly. Many areas 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 and other parts of the machines causing damage and a loss of
cleaning effectiveness. This inuences the reliability and efciency 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 machine’s warranty, HydraMaster requires that all machines operating in
designated “Hard Water Areas” (3.0 grains or more per gallon) be tted with a water
softening system, or a properly installed magnetic-type descaler must be used and
maintained. Periodic descaling 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 descaling agents.
HydraMaster also recommends, in the strongest possible terms, that machines in all areas
be tted with a water softening system for improved operation and reliability.
Failure to take appropriate measures to prevent scale build up can result in system failure
and loss of warranty on affected parts.

General Information: 1-10
HARD WATER AREA MAP
The hard water map, shown in Figure 1-1, denes hard water areas in the lower 48 United
States which compromise uid related components such as hoses, ttings, heaters,
pumps, valves and water-cooled engines. For other countries, hard water area maps can
be obtained from geological societies.
The map shown in Figure 1-1 is provided for general reference only. Water hardness in
your geographical location should be conrmed by testing.
Figure 1-1. Hard Water Map of Mainland United States

1-11: General Information
WATER SOFTENER
Cleaning efciency and equipment life is increased, chemical use decreased, and the
appearance of cleaned carpets enhanced when water softeners are incorporated in
hard water areas. HydraMaster strongly urges the use of water softener units with the
CDS 4.8/4.6 machines in areas exceeding 3.0 grains per gallon (see Figure 1-2).
Failure to use a water softener in these areas will invalidate the machine’s warranty.
Referring to the hard water area map shown Figure 1-1, determine the quality of water in
your area and take immediate action if
the water hardness exceeds 3.0 grains
per gallon.
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 efciency. The water softener
will also increase the effectiveness of
the cleaning chemicals, therefore less
chemical will be needed.
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.

General Information: 1-12
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.
The cleaning rinse water, recovered into your unit’s vacuum tank, contains materials
such as detergents, and must be safely processed before entering streams, rivers and
reservoirs.
In most cases, an acceptable method of waste water disposal is to discharge into a
municipal sewage treatment system after rst ltering out solid material such as carpet
ber. Access to the sanitary system can be obtained through a toilet, laundry drain, RV
dump, etc. Permission should rst be obtained from any concerned party or agency.
One disposal method which usually complies 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 your CDS with an Automatic Pump-Out System (APO). These systems are
designed to remove waste water from the extractor’s recovery system and actively pump
the water through hoses to a suitable disposal drain.
HydraMaster makes an APO System which can be ordered with new equipment or
installed later.
When properly congured, the systems will continuously monitor the level of waste water
and pump it out simultaneously with the cleaning operation. The hidden benet of this
process is that the technician does not have to stop his/her cleaning to empty the recovery
tank.
IN ACCORDANCE WITH EPA, STATE AND LOCAL LAWS, DO NOT DISPOSE OF
WASTE WATER INTO GUTTERS, STORM DRAINS, STREAMS, RESERVOIRS, ETC.
The penalties for non-compliance can be serious. Always check local laws and regulations
to be sure you are in compliance.
