CTS 330 Hot Carbonating Truckmount System
This manual contains installation and operation instructions as well as information
required 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 simulta-
neously.
• The engine has to run at a consistent rpm.
• The vacuum has to pull air and dirty water back from cleaning site.
• The solution system provides stable pressure at proper water flow for cleaning.
• The heating system must maintain proper heat.
• The vacuum tank must store dirty water until drained.
As you can see, this machine is not just a simple turn-key operation where your only worry
is “Does it start?”

Precautions
1. Engine Cooling
Units employing internal combustion engines must not be enclosed within a van with
doors and windows closed. Excessive temperatures within the engine will result in pre-
mature engine failure and a compromise of applicable warranty.
2. Level Operation
During operation, van or trailer 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.
3. Moving Parts
Never touch any part of the machine that is in motion. Severe bodily injury may result.
4. Freeze Protection
There is often little warning before a cold spell. Failure to protect this equipment from
freezing will result in costly down time. Placing an electric heater in the truck or parking
thetruck indoors will helpto insureagainst freezing,but shouldnot bethe primarymethod
of freeze protection.
5. Exhaust System
Do not allow flammable material (i.e. oil, fuel, plastic, or wood products) to come in con-
tact with the exhaust system.
6. Hot Surfaces
During the operation of this equipment, many surfaces on the machine will become very
hot. When standing in the proximity of the van, care must be taken not to touch any hot
surface such as the heater, engine, exhaust, and etc.

7. Hearing Protection
TheOccupationalSafety andHealthAdministration (OSHA)recommendsthe useofhearing
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 OSHAstandards apply to
your machine use.
8. 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.
9. Toxic Fumes
Do not occupy the vehicle when the cleaning equipment is operating. Toxic fumes may
accumulate inside a stationary vehicle.
10. 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.
11. Carburetor Drain
Under no circumstances should the drain in the carburetor bowl be used when the ma-
chine is hot.
12. Portable Gas Tank
Never operate this machine with a portable gas can inside the truck. Doing so increases
the risk of a fire or explosion.

14. Vacuum System
When machine is being run for test purposes and the vacuum inlet on top of the machine
is open, caution should be used.
To protect the vacuum blower from over loading and damaging itself, there is a vacuum
relief system installed on the vacuum tank. When the vacuum tank inlet is completely
sealed off, a maximum of 12 inches Hg will be attained. At the end of each day, an oil
based lubricant should be sprayed into the blower lubrication port before shutting down
the machine. If this operation is not performed daily the vacuum blower will develop rust
deposits from moisture and will decrease the life of the vacuum blower.
15. Vacuum Tank
Foam passing through the blower could lead to equipment malfunction. Therefore, it is
important to keep the vacuum tank foam free.
16. Vacuum Hose
Do not leave the vacuum hose unattended during operation. This could cause bodily
injury.

Vehicle Preparation
When selecting a truck, remember the preferable vehicle for a CTS 330
installation is a cargo van with a heavy-duty suspension package and a half ton
capacity. If a fresh water tank is added, a three quarter ton or larger capacity van, with a
2,400 pound payload capacity, is required.
TRUCK PREPARATION
The manufacturer recommends the installation of a spray-on bed liner in the vehicle prior
to installation of machine.
Be cautious when drilling any 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 92101, 94062,
and 94063 at the end of this manual.)
This provides ‘metal to cushion’ mounting rather than ‘metal to metal’ and makes for an
attractive van interior. It is highly recommended to install roof vents in vehicles operated in
hot weather locations. Roof vent positions are shown in Figure 1-1.

PLACEMENT OF UNIT IN VEHICLE
There are two recommended unit placements:
SIDE DOOR:
Most installations are side door. This provides rear access for accessories and hoses
as well as unobstructed access to the component/working side of the
machine, thus making it a bit easier to perform maintenance and/or repair without
removing the unit from the truck.
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 over the rear wheels for better traction in ice and snow. Rear mount-
ing requires the unit to be slid to the right side as far as possible.
This not only provides adequate working space on the component side of the unit but
also improves weight distribution inside the van (engine and component weight line
up over drive shaft). Also, it is physically easier to load the unit into the rear door due
to the height of the van bed.
Figure 1-2 Recommended Placement

HydraMaster Corporation
Page 1-10 : CTS 330 Owner’s Manual
CTS 330Hot Carbonating Truckmount System
Machine Tie Down Cleats
Secure the machine to the oor of the van with the four tie down cleats provided (See
Figure 1-4). This safety measure will ensure that the machine will not slide inside the van.
See the following illustration for the correct installation.
Figure 1-4 Installation Using Tie-down Cleats
Ensure that the machine is well secured to the oor of the van with the hardware supplied.
A sudden or crash stop will cause the machine to rocket forward. Protect yourself and the
machine. SECURE IT!
It is recommended by the manufacturer that the exhaust from the front of the machine
be vented down under the truck to prevent carbon monoxide from entering the job site.
Always park the truck so the exhaust is blowing away from the job site.
The manufacturer also recommends the installation of 12 volt powered vents in the truck
roof to allow heat to escape.
Never operate this machine with a portable gas can inside the truck. Doing so increases
the risk of a re or explosion.
Mount a re extinguisher just inside the rear or side door for emergencies.

Do not use a portable propane tank inside of the truck or van. It is dangerous and illegal
in most states.
Transportation in a vehicle of any vented fuel container that presently holds or has ever
held a ammable liquid is strictly forbidden by HydraMaster Corporation and by federal
and state regulation.
The engine exhaust from this product contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm.
If the battery location is at your option, rst make sure it is in an approved battery container
and that it is covered and secured to the oor of the vehicle. Make sure the battery is
isolated from hot machine components. This will cause the battery to last longer and also
prevent the possibility of re or explosion.

High Altitude Operation
Preparation
To have your machine run at it’s peak performance; you may have to make adjustments
depending on the elevation. Elevation plays a key role in how the machine will operate.
The factory setting of the machine is set for elevations from 0—3,000 feet. Any time the
machine is operated above 3,000 feet there are two areas on the machine the may need
adjustment.
The first area is the carburetor jet. The higher the elevation, the less air is provided to the
fuel mixture. This will make the engine run ‘rich’, and, in turn will result in the loss of
power, excessive heat in the exhaust, and carbon buildup in the exhaust and heat ex-
changer system. The jet sizes vary per engine and elevation. Consult HydraMaster to
obtain proper jet size.
The second area that may need adjustment is the heat control system. The heat control
system is also optimized to 0-3,000 feet. At higher altitudes the boiling point of water is
lowered. In turn, this can cause the water box to boil and the high pressure pump to
cavitate. The heat control system settings will have to be adjusted to compensate for the
elevation. These settings will vary according to elevation. Contact HydraMaster to obtain
the recommended settings.
