1-3: General Information
SYSTEM CONCEPT
The Titan 875’s system utilizes an internal combustion engine to provide the power
necessary to turn both the vacuum blower and the high pressure water pump.
The heat from the engine and blower exhausts is transferred to the high pressure water
in the nned tube heat exchanger and copper tube and shell of the system. Finally, the
chemical is injected into the pressurized water stream and the heated solution is delivered
to the cleaning tool.
Solution is recovered by the vacuum generated by the vacuum blower and is collected in
the recovery tank for proper disposal.

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: 1-6
Warnings and Cautions specic to the Titan 875 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 HealthAdministration (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.
Duringthe operation of the truckmount, chemicals knownto the Stateof 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.

1-7: General Information
Transportingaventedfuelcontainerthatpresentlycontains,orhasevercontained
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.
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 personal injury
and property damage may result.
Never operate the truckmount when the vehicle is tilted more than 10 degrees in
anydirection.Doingsowillresultinimproperlubricationoftheinternalcomponents,
and will increase the risk 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
extremelyhightemperaturesinsidethevehicleandwillleadtoseriouscomponent
or engine damage.
Neveruseconcentratedacidsorsolvents(includingd-limonene)inthetruckmount
water system or chemical system. Use of these products will cause serious
component damage.

General Information: 1-8
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.
Never allow water to freeze inside the truckmount. Serious component damage
will occur. Perform all freeze guarding procedures as outlined in Section 4 of this
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.
