Safety Precautions
WARNING: Failure to follow these precautions can result in serious injury or death.
• Your VCX Vacuum Coolant Exchanger was developed to provide you with years of trouble-free service in
accordance with the utilization of proper inspection and maintenance techniques. It is important to understand
this machine functions with its coolant cylinders either under pressure or vacuum, so it is imperative all cylinders
receive proper inspection to ensure the proper and safe operation of the equipment is maintained throughout its
life cycle.
• Read and understand the Operation Manual completely before operating this unit.
• Always wear proper skin protection when operating and maintaining this equipment.
• Always wear safety glasses when operating and maintaining this equipment.
• Before any VCX machine use it is required for the operator to visually inspect the coolant cylinders for defects
such as cracks, nicks, gouges, chips, impact marks, fractures, hairline cracks, crazing, severe discoloration,
cloudiness or hazing or other physical damage. VISUAL TUBE INSPECTION IS REQUIRED PRIOR TO EACH
MACHINE USE! IF ANY TUBES EXHIBIT ANY DEFECTS, THEY MUST BE REPLACED BEFORE MACHINE
OPERATION! FAILURE TO COMPLY MAY RESULT IN TUBE FAILURE AND POSSIBLE INJURY!
• Automotive cooling systems can be under pressure and extremely hot. Place a rag over the radiator cap during
removal to avoid injury. Use extreme caution when removing caps.
• Coolants are corrosive and poisonous to people and animals. Clean up any spills immediately.
• Do not allow waste coolant tank to overflow. Immediately clean up any coolant spills. Damage to the vehicle and
equipment can result from the corrosiveness of coolant.
• Continuous monitoring of the coolant exchange process is required.
• Unit is equipped with factory preset pressure regulator. Do not attempt pressure adjustment without RTI
Technical Support authorization.
• If cracks appear in the cylinders, hoses or adapters these parts must be replaced.
• If VCX unit tipped over, resulting in a fall of the machine onto any side, it is mandatory all
replaced immediately before the machine is placed back into service.
• If leaks occur at the bottom or top of the cylinders, contact RTI for troubleshooting instructions.
• The cylinders, hoses and adapters are plastic and rubber products and are in contact with oil and chemicals
which may lessen their durability. Therefore, when soiled, they should be cleaned with water and a mild
detergent. Caution: Do not clean with thinners, solvents or any other chemical cleaners.
• Only disassemble or reassemble unit parts when directed by an RTI representative.
• Take precautions to keep clothing, hair, hands, hoses, etc. away from all moving parts of the vehicle.
• Comply with local, state and federal regulations for fluid disposal.
• Material Safety Data Sheets (MSDS) must be obtained on all chemicals and placed in a shop file for reference.
These are available for down load and printing on the RTI web-site (www.rtitech.com). Go to TECHNICAL HELP
and look under Technical Bulletins.
