Safety Precautions Danger, Warning, Caution, and Notice Thermo King ® recommends that all service be performed by a Thermo King dealer and to be aware of several general safety practices.

The four types of advisories are defined as follows: DANGER Hazard! Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING Hazard! Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION Hazard!
Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury and unsafe practices. NOTICE Hazard! Indicates a situation that could result in equipment or property-damage only accidents. Recover Refrigerant At Thermo King ® , we recognize the need to preserve the environment and limit the potential harm to the ozone layer that can result from allowing refrigerant to escape into the atmosphere. We strictly adhere to a policy that promotes the recovery and limits the loss of refrigerant into the atmosphere.
When working on transport temperature control systems, a recovery process that prevents or minimizes refrigerant loss to the atmosphere is required by law. In addition, service personnel must be aware of the appropriate European Union, National, Federal, State, and/or Local regulations governing the use of refrigerants and certification of technicians. For additional information on regulations and technician programs, contact your local THERMO KING dealer. Service Tools - Use the proper service tools. Gauge manifold sets should include appropriate shutoff valves or disconnects near the end of each service line. Recovery Equipment - Recovery equipment must be used.
Proper recovering, storing and recycling of refrigerants is an important part of all service work. Service Procedures - Recommended procedures must be used to minimize refrigerant loss. Components may be isolated by closing service valves and performing system pump-downs. Components unable to be isolated for service must be repaired only after refrigerant is properly recovered.
