SAFETY PRECAUTIONS
1.1 SAFETY PRECAUTIONS
SAFETY CONSIDERATIONS: Installation and servicing of refrigeration equipment can be
hazardous due to system pressures, rotating elements and electrical components. Only trained
and qualified service personnel should install, repair or service refrigeration equipment. When
working on refrigeration equipment, observe precautions in all literature including this manual,
the equipment tags and labels attached to the unit, and other safety precautions that may
apply. Follow safe work practices and utilize the appropriate protective equipment at all times.
Your Carrier Transicold refrigeration unit has been designed with the safety of the operator in mind. During normal
operation, all moving parts are fully enclosed to help prevent injury. During all pre-trip inspections, daily
inspections, and problem troubleshooting, you may be exposed to moving parts. Please stay clear of all moving
parts when the unit is in operation and when the START/RUN-OFF switch (SROS) is in the START/RUN position.
Electronic modules MUST be handled with care to prevent accidental damage or degradation
from electrical static discharge (ESD), contamination or abuse. Before touching a module,
touch your body and/or conductive tool being used to the frame to discharge ESD safely. All
electronics should be handled carefully and only held by edges of any exposed board. Care
should be taken when inserting/extracting connectors and components to avoid exerting
excessive stress on the board which could fracture small components nearby, resulting in
future failure of circuit.
Under no circumstances should a technician electrically probe the modules at any point, other
than the connector terminals where the harness attaches. Module components operate at
different voltage levels and at extremely low current levels. Improper use of voltmeters, jumper
wires, continuity testers, etc. could permanently damage the module.
Automatic Start-Stop
Your refrigeration unit is equipped with auto-start in both Start-Stop and Continuous Operation. The unit may start
at any time the START/RUN-OFF switch (SROS) is in the START/RUN position. A buzzer will sound for 5 seconds
before the unit is started. When performing any check of the refrigeration unit (e.g. checking the electrical
connections), make certain that the START/RUN-OFF switch is in the OFF position.
Refrigerants
The refrigerant contained in the refrigeration system of this unit can cause frostbite, severe burns, or blindness
when in direct contact with the skin or eyes. For this reason (and because of legislation regarding the handling of
refrigerants) we recommend that you contact your nearest Carrier Transicold authorized repair facility whenever
service of the refrigerant system is required.
Battery
This unit may be equipped with a lead-acid type battery. The battery normally vents small amounts of flammable
hydrogen gas. Do not smoke when checking the battery. A battery explosion can cause serious physical harm and/
or blindness.
