Safety Precautions

WARNING: Failure to follow these precautions can result in serious

injury or death.

• Read and understand the Operation Manual completely before operating this unit.

• Always wear proper eye and skin protection when operating and maintaining this equipment.

• Automotive cooling systems can be under pressure and extremely hot. Use extreme caution
when removing caps. Place a rag over the radiator cap during removal.

• Coolants are poisonous to people and animals and are also corrosive. 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.

• If cracks appear in the cylinders, hoses, or adapters these parts must be replaced.

• If leaks occur at the bottom or top of the cylinders the center nut located under the top cover plate
will need to be tightened. (see page 13 for 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.

CAUTION: Failure to follow the precautions as outlined in the operation manual can

result in damage to the engine, vehicle or equipment which will not be
supported or covered under warranty.
