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.
Page 12
Warnings and Cautions specific 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.
Page 13
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.
Responsibilities Prior to the arrival of the unit, the van that it will be installed in should be delivered to the installer. Purchaser’s Responsibility If you are the purchaser, it is the your responsibility to read the owner’s Manual and to familiarize yourself with the information contained herein, paying special attention to all Warnings and Cautions.
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.
HARD WATER AREA MAP The hard water map, shown in figure 1-1, defines hard water areas in the lower 48 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.
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. 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).
HydraMaster makes an APo System which can be ordered with new equipment or installed later. When properly configured, the systems will continuously monitor the level of waste water and pump it out simultaneously with the cleaning operation.
2 - Chemicals and Cleaning your mobile carpet cleaning plant has been engineered using the latest and most sophisticated technology available to produce the finest carpet cleaning results possible. Despite this, it remains only a tool of the carpet cleaning trade and can produce only as a good a job as the person operating it.
HydraMaster will not warranty parts that have been damaged from using acid products that have obviously caused failures. Avoid using detergents and chemicals which create foam when those products are agitated because foam passing through the blower could lead to serious mechanical failures.
Figure 2-2. Cleaning Stroke Procedure failure to adopt the previous procedure can result in increased chance of “clean streaks,” fiber shrinkage, brown-out and longer drying periods. OVERWETTINg overwetting is annoying to all concerned, and sometimes leaves the customer with a bad impression of the cleaning process used.
3 - operating Instructions This section of the manual contains the following instructions: Before operating the CDS CDS Start up CDS flood Restoration Work CDS Shut Down 3 Speed Throttle Control function BEFORE OPERATINg THE CDS locate the unit and equipment in a well-ventilated area.
CDS START UP Make sure the vehicle’s gear select lever is in the Park position and the emergency brake is set Start the vehicle’s engine. Turn key on the CDS dash. Select the cleaning speed appropriate for the cleaning job. Turn on the PuMP CluTCH switch.
CDS SHUT DOWN flush clear water through the chemical system for 10 seconds. open the water box drain and actuate the tool/wand valve to run fresh water through the water box, heat exchangers and cleaning tools. If freeze guarding is necessary, perform the freeze guard procedure at this time. Draining the water box to ½...

4 - freeze Guard When operating the CDS 4.8 / 4.6 during the colder months of the year, ensure that you properly freeze guard the system. No part of the CDS 4.6/4.8 System is covered by warranty if machine damage occurs because of freezing.
DRAININg THE CDS To drain the machine, follow these steps: Before shutting off the machine, remove the chemical line from the chemical jug and place in a mixture of 50/50 antifreeze and water. Turn the CHeMICAl SySTeM valve to the “PRIME” position until coolant registers in the flow meter. With the cleaning tool on, allow mixture to fill the remainder of the chemical system.
FREEZE PROTECTINg PUMP-IN SYSTEM Drain the fresh water tank. Remove the fresh water (garden) hose adapter from the pump-in pump hose and position the hose so it is pointing outside the van. Turn on the pump-in pump and run for 1 - 2 minutes until all the water is purged from the hose.
5 - Water and Chemical System The CDS 4.8 / 4.6 high-pressure water and chemical system has been designed to be simple and trouble free. This section of the manual explains: Water and Chemical flow operation Chemical System Maintenance ...
CHEMICAL SYSTEM MAINTENANCE The chemical lines may need to be flushed with vinegar periodically to prevent abnormal chemical build-up. To flush the chemical system: Set the CHeMICAl floWMeTeR to10 gph. Remove the clear plastic hose from the chemical jug and insert it into a 1-quart container of vinegar.

8 - Vacuum Blower System This section of the manual covers the CDS’ vacuum blower system and includes information on: Vacuum Tank Inlet filter Vacuum Blower lubrication Vacuum Blower Troubleshooting The vacuum blower, featuring tri-lobe rotors, is designed for maximum positive displacement and manufactured using special porting technology to significantly reduce noise.
The switch is not activated by foam, only by liquid. VACUUM TANK INLET FILTER HydraMaster inlet filter screens are designed to trap lint, hair and large objects that would normally collect at the bottom of your vacuum tank. Clean the screen at the end of each job to eliminate build-up of debris in the tank.

4.0. Noisy Vacuum Blower 4.1.Vacuum blower is low on Inspect oil level and replenish as necessary oil. Running the blower when it is low on oil will cause severe internal damage to the blower. If this situation occurs, the blower should be inspected by a qualified service technician.
Because the most difficult problem to trace in any system is often an electrical failure, HydraMaster has designed the CDS’ electrical system with the technician in mind. This section of the manual includes CDS wiring schematics and diagrams as well as troubleshooting guides.
electrical Troubleshooting 1.0. CDS WILL NOT TURN ON 1.1. The main power fuse Remove CDS cowling and engine cover and check all has blown. wiring from the power source back to the CDS console for damage. Replace fuse only after locating the problem that caused the fuse to blow.
Records of maintenance must be kept and copies may be required to be furnished to HydraMaster before the warranty is honored. It is recommended that you affix a copy of the log on the vehicle door near your unit for convenience and to serve as a maintenance reminder.

Daily • Check engine oil level. • Inspect fresh water (garden) hose screen. Clean as needed. • Empty waste tank inlet filter. • Visually inspect machine for loose wires, oil leaks, water leaks, etc. • Inspect vacuum tank stainless steel filter for clogging or damage. Clean, repair or replace as needed.
Page 116
Quarterly • Change oil in blower. • Change oil in pump. • Check the vehicle fuel lines for any chafing or wear, especially in the engine compartment or near any rotating parts. • Check the CDS wiring harness for any chafing or wear, especially in the vehicle engine compartment or near any rotating parts.
APPEARANCE MAINTENANCE Maintaining the original appearance of your unit is important for two reasons: It represents a big dollar investment for your cleaning business and its appearance should reflect that fact. A dirty machine does not look professional. Maintenance, troubleshooting and repair is much easier to accomplish on a clean, well-maintained unit.
Long-Term Maintenance Schedule The following components or systems should be serviced or replaced at the specified intervals. Component Interval (Machine hours / months of service) High pressure water pump rebuild 2,000 / 24 Vehicle engine thermostat 2,000 / 24 Vehicle engine accessory drive belt 2,000 /24 CDS clutch 3,000 / 36...
