Safety Precautions

NOTE: In the USA, EPA Section 608
Certification is required to work on refrigeration
systems.
Battery Installation and Cable
Routing
Battery Removal
This order is important because the frame is
grounded to the negative battery terminal. If the
negative terminal is still connected, a complete
circuit exists from the positive terminal of the
battery to the frame. Metal objects contacting the
positive side and the frame simultaneously will
cause sparks or arcing. If there are sufficient
hydrogen gases emitted from the battery, an
explosion might occur, causing equipment
damage, serious injury, even death.
Refrigerant Hazards
WARNING: 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.
WARNING: 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.
WARNING: Do not attach fuel lines or
any additional wiring harnesses to the
battery cables as this could cause an
electrical fire!
CAUTION: 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!
CAUTION: 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.
CAUTION: 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.
CAUTION: 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.
DANGER: Disconnect the negative
battery terminal (-) first when removing a
battery. Connect the positive terminal (+)
first when installing a battery.
DANGER: Do not use a Halide torch.
When a flame comes in contact with
refrigerant, toxic gases are produced.
These gases can cause suffocation, even
death.
DANGER: Store refrigerant in proper
containers, out of direct sunlight and away
from intense heat. Heat increases pressure
inside storage containers, which can cause
them to burst.
DANGER: Do not use oxygen (O
2
) or
compressed air for leak testing. Oxygen
mixed with refrigerant is combustible.
WARNING: Wear butyl lined gloves when
handling refrigerant to help prevent
frostbite.
