Safety Precautions 2-1
2 Safety Precautions
Thermo King recommends that all service be performed by a Thermo King dealer. However, you should be aware of several
general safety practices:
GENERAL PRACTICES
1. ALWAYS WEAR GOGGLES OR SAFETY GLASSES. Refrigerant liquid and battery acid can permanently damage the
eyes (see First Aid).
2. Never close the compressor discharge service valve with the unit operating. Never operate the unit with the compressor
discharge valve closed. This condition increases internal pressure, which can cause an explosion.
3. Keep your hands clear of the fans and belts when the unit is operating. This should also be considered when opening and
closing the compressor service valves.
4. Make sure the gauge manifold hoses are in good condition. Never let them come in contact with a belt, fan motor pulley, or
any hot surface.
5. Never apply heat to a sealed refrigeration system or container.
6. Fluorocarbon refrigerants, in the presence of an open flame or electrical short, produce toxic gases that are severe respiratory
irritants.
7. Make sure all mounting bolts are tight and are of the correct length for their particular application.
8. Use extreme caution when drilling holes in the unit. The holes may weaken structural components, and holes drilled into
electrical wiring can cause fire or explosion.
9. Use caution when working around exposed coil fins. The fins can cause painful lacerations.
10. Use caution when working with a refrigerant or refrigeration system in any enclosed or confined area with a limited air supply
(for example, a truck body or garage). Refrigerant tends to displace air and can cause oxygen depletion which may result in
unconsciousness or death from suffocation.
11. Use caution and follow the manufacturer’s suggested practices when using ladders or scaffolds.
AUTO START/STOP CONTROLS
Units equipped with a CYCLE-SENTRY Automatic Start-Stop system may start automatically at any time when the unit is on
and CYCLE-SENTRY is the selected mode. Be sure to turn the On/Off switch “Off” before opening unit service doors or
inspecting or working on any part of the unit.
BATTERY INSTALLATION AND CABLE ROUTING
1. Improperly installed battery could result in a fire or explosion! A Thermo King approved battery must be installed and
properly secured to the battery tray.
2. Improperly installed battery cables could result in fire or explosion! Battery cables must be installed, routed and secured
properly to prevent them from rubbing, chaffing or making contact with hot, sharp or rotating components.
3. Do not attach fuel lines or any additional wiring harnesses to the battery cables as this could cause an electrical fire!
4. Do not connect other manufacturer’s equipment or accessories to the Thermo King unit. This could result in severe damage
to equipment and void the warranty!
5. Set all unit electrical controls to the OFF position before connecting battery cables to the battery to prevent unit from starting
unexpectedly and causing personal injury.
6. Always wear protective clothing, gloves and eye wear when handling and installing batteries. Battery acid can cause serious
burns when exposed to eyes or skin. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention
immediately.
7. Always cover battery terminals to prevent them from making contact with metal components during battery installation.
Battery terminals grounding against metal could cause the battery to explode.
