and also emphasizes supplemental information.

TITAN 425 Owner’s Guide - 4
Warnings and Cautions specic to the Titan 425 include the following:
During the operation of the truckmount many components are in motion. Never
touch any part of the truckmount that is in motion. Serious injury may result.
During the operation of the truckmount many surfaces will become extremely hot.
Never touch hot surfaces. Serious injury may result.
The operation of this truckmount can produce noise levels exceeding 85 decibels
to a distance of 10 ft. The Occupational Safety and Health Administration (OSHA)
recommends the use of hearing protective equipment if a person is exposed
to an average of 85 decibels over an 8-hour period. Check with local and state
agencies concerning hearing conservation rules.
During the operation of the truckmount carbon monoxide and other toxic fumes
are produced. Position the vehicle so that any fumes produced will be directed
away from inhabited areas and any points of building entry (doors, windows, air
conditioning units, fans, etc.). Do not occupy the vehicle while the truckmount is
in operation. Serious injury may result.
During the operation of the truckmount, chemicals known to the State of California
to cause cancer, birth defects and other reproductive harm are produced by the
engine exhaust.
Never operate the truckmount with a portable gas container inside the vehicle.
Doing so will increase the risk of re and explosion. Serious injury or death may
result.
Transporting a vented fuel container that presently contains, or has ever contained
in the past, a ammable liquid is strictly forbidden by HydraMaster and by federal
and state regulations. Doing so will increase the risk of re and explosion. Serious
injury or death may result.

5 - TITAN 425 Owner’s Guide
Never smoke in or around the truckmount. Doing so will increase the risk of re
and explosion. Serious injury or death may result.
During the operation of the truckmount the exhaust system will become extremely
hot. Keep all ammable materials away from the truckmount exhaust system.
Failure to do so will increase the risk of re and explosion. Serious property
damage may result.
Never operate the truckmount when the vehicle is tilted more than 10 degrees
in any direction. Doing so will result in improper lubrication of the internal
components, and will increase the risk of serious component or engine damage.
Never perform cleaning operations when the truckmount engine is running at the
IDLE throttle position. Failure to do so will increase the risk of serious component
or engine damage.
Never operate the truckmount with the vehicle doors closed. Doing so results in
extremely high temperatures inside the vehicle and will lead to serious component
or engine damage.
Never use concentrated acids or solvents (including d-limonene) in the truckmount
water system or chemical system. Use of these products will cause serious
component damage.
Never operate the truckmount with a water hardness reading measuring 3.0
grains per gallon or higher. Using reading than 3.0 grains per gallon will cause
scale to build up inside the truckmount water system. Scale build up causes
serious component damage. Test all water prior to use and use water softening
equipment if necessary.

TITAN 425 Owner’s Guide - 6
Never allow water to freeze inside the truckmount. Serious component damage
will occur. Perform all freeze guarding procedures outlined in this digital Owner’s
Manual.
Many vehicles have critical components mounted directly below the oor that
can easily be damaged. Before drilling holes in the oor of the vehicle inspect
the underside of the vehicle for critical components. Failure to do so may result
in damage to the vehicle.
Use of the vacuum recovery system when stripping or otherwise removing wax
from oors is specically excluded as an approved use of the truckmount. Failure
to follow this exclusion may lead to component failure and will invalidate your
warranty.
Use of the vacuum recovery system for “dry cleaning”, without corresponding
solution application (i.e. duct cleaning), is specically excluded as an approved
use of the truckmount. Failure to follow this exclusion may lead to component
failure and will invalidate your warranty.
If concentrated acids or solvents are used to pre-treat surfaces before power
washing, do not recover them through the vacuum system. Failure to follow this
exclusion may lead to component failure and will invalidate your warranty.

HIGH ALTITUDE OPERATION
Elevation plays a key role in how the truckmount will operate. Operation at high altitude
(above 5,000 ft [1,524 m]) may require a high-altitude carburetor jet. Use of this jet at high
altitude will improve power, reduce fuel consumption and help reduce excessive carbon
build-up in the exhaust and heat exchanger systems.
Contact the local Briggs and Stratton dealer or HydraMaster to obtain
the proper jet size. Find your local Briggs and Stratton dealer at
http://www.vanguardengines.com/where-to-buy/dealer-locator/
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 e󰀨ectiveness. This inuences the reliability and e󰀩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 [3.79 litres]) 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
e󰀨ectiveness 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 a󰀨ected parts.

TITAN 425 Owner’s Guide - 14
Hard Water Area Map
The hard water map, shown in Figure 1, denes hard water areas in the continental 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.
Figure 1. Hard Water Map of Mainland United States
The map shown in Figure 1 is provided for general reference only. Water hardness
in your geographical location should be conrmed by testing.

15 - TITAN 425 Owner’s Guide
Water Softener
Cleaning e󰀩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 Titan
425 in areas exceeding 3.0 grains per gallon.
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, 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 e󰀩ciency. The
water softener will also increase the e󰀨ectiveness 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 charge 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/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 charged every 6 working days for maximum softening.

TITAN 425 Owner’s Guide - 16
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 Titan 425 with an Automatic Wastewater Disposal System (AWDS). 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 AWDS 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.
INACCORDANCE WITH EPA, STATEAND 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.

The lower dash houses the controls for:
• Water pressure
• Chemical system
• Water box drain
The lower dash assembly also houses the blower lube port and the solution out port
where the wand/tool connects to the Titan 425 (see Figure 3).
To ensure proper operation of the exhaust diverter system, the TITNA 425 must
have a minimum of 10” Hg vacuum. If the vacuum level is lower than 10” Hg, the
exhaust diverter will remain in “Divert” mode.
Photographs and illustrations included in this document can represent optional
equipment as well as standard equipment.
Never perform cleaning operations when the truckmount engine is running at
the IDLE throttle position. To do so will increase the risk of serious component or
engine damage.
