SAFETY SUMMARY
1.1 GENERAL SAFETY NOTICES
The following general safety notices supplement specific warnings and cautions appearing elsewhere in this man-
ual. They are recommended precautions that must be understood and applied during operation and maintenance
of the equipment covered herein. The general safety notices are presented in the following three sections labeled:
First Aid, Operating Precautions and Maintenance Precautions. A listing of the specific warnings and cautions
appearing elsewhere in the manual follows the general safety notices.
1.2 FIRST AID
An injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention immediately.
1.3 OPERATING PRECAUTIONS
Always wear safety glasses.
Keep hands, clothing and tools clear of the evaporator and condenser fans.
No work should be performed on the unit until all circuit breakers and start-stop switches are turned off, and power
supply is disconnected.
In case of severe vibration or unusual noise, stop the unit and investigate.
1.4 MAINTENANCE PRECAUTIONS
Beware of unannounced starting of the evaporator and condenser fans. Do not open the condenser fan grille or
evaporator access panels before turning power off, dis connecting and securing the power plug.
Be sure power is turned off before working on motors, controllers, solenoid valves and electrical control switches.
Tag circuit breaker and power supply to prevent accidental energizing of circuit.
Do not bypass any electrical safety devices, e.g. bridging an overload, or using any sort of jumper wires. Problems
with the system should be diagnosed, and any necessary repairs performed by qualified service personnel.
When performing any arc welding on the unit or container, disconnect all wire harness connectors from the mod-
ules in control boxes. Do not remove wire harness from the modules unless you are grounded to the unit frame
with a static safe wrist strap.
In case of electrical fire, open circuit switch and extinguish with CO2(never use water).
1.5 SPECIFIC WARNING AND CAUTION STATEMENTS
To help identify the label hazards on the unit and explain the level of awareness each one carries, an explanation is
given with the appropriate consequences:
DANGER
!
DANGER - means an immediate hazard that WILL result in severe personal injury or death.
WARNING
!
WARNING - means to warn against hazards or unsafe conditions that COULD result in severe
personal injury or death.
CAUTION
!
CAUTION - means to warn against potential hazard or unsafe practice that could result in
minor personal injury, product or property damage.

T-359 1–2
The statements listed below are applicable to the refrigeration unit and appear elsewhere in this manual. These
recommended precautions must be understood and applied during operation and maintenance of the equipment
covered herein.
DANGER
!
Never use air for leak testing. It has been determined that pressurized, mixtures of refrigerant
and air can undergo combustion when exposed to an ignition source.
WARNING
!
Beware of unannounced starting of the evaporator and condenser fans. The unit may cycle the
fans and compressor unexpectedly as control requirements dictate.
WARNING
!
Do not attempt to remove power plug(s) be fore turning OFF start-stop switch (ST), unit circuit
breaker(s) and external power source.
WARNING
!
Make sure the power plugs are clean and dry before connecting to power receptacle.
WARNING
!
Make sure that the unit circuit breaker(s) (CB-1 & CB-2) and the START-STOP switch (ST) are in
the “O” (OFF) position before connecting to any electrical power source.
WARNING
!
Make sure power to the unit is OFF and power plug disconnected before replacing the com-
pressor.
WARNING
!
Before disassembly of the compressor, be sure to relieve the internal pressure very carefully
by slightly loosening the couplings to break the seal.
WARNING
!
Do not use a nitrogen cylinder without a pressure regulator. Do not use oxygen in or near a
refrigeration system as an explosion may occur.
WARNING
!
Do not open the condenser fan grille before turning power OFF and disconnecting power plug.
WARNING
!
Always turn OFF the unit circuit breakers (CB-1 & CB-2) and disconnect main power supply
before working on moving parts.

1–3 T-359
WARNING
!
Always turn OFF the unit circuit breakers (CB-1 and CB-2) and disconnect main power supply
before working on moving parts.
WARNING
!
Installation requires wiring to the main unit circuit breaker, CB1. Make sure the power to the
unit is off and power plug disconnected before beginning installation.
CAUTION
!
Charge receiver according to nameplate specifications to ensure optimal unit performance.
CAUTION
!
Do not remove wire harnesses from controller modules unless you are grounded to the unit
frame with a static safe wrist strap.
CAUTION
!
Unplug all controller module wire harness connectors before performing arc welding on any
part of the container.
CAUTION
!
Do not attempt to use an ML2i PC card in an ML3 equipped unit. The PC cards are physically
different and will result in damage to the controller.
CAUTION
!
Pre-trip inspection should not be per formed with critical temperature cargoes in the container.
CAUTION
!
When Pre-Trip key is pressed, economy, de humidification and bulb mode will be deactivated.
At the completion of Pre-Trip activity, economy, dehumidification and bulb mode must be reac-
tivated.
CAUTION
!
When a failure occurs during automatic testing, the unit will suspend operation awaiting oper-
ator intervention.
CAUTION
!
When Pre-Trip test Auto 2 runs to completion without being interrupted, the unit will terminate
pre-trip and display “Auto 2" “end”. The unit will suspend operation until the user depresses
the ENTER key!

T-359 1–4
CAUTION
!
Allowing the scroll compressor to operate in reverse for more than two minutes will result in
internal compressor damage. Turn the start-stop switch OFF immediately.
CAUTION
!
To prevent trapping liquid refrigerant in the manifold gauge set be sure set is brought to suc-
tion pressure before disconnecting.
CAUTION
!
The scroll compressor achieves low suction pressure very quickly. Do not use the compressor
to evacuate the system below 0 psig. Never operate the compressor with the suction or dis-
charge service valves closed (frontseated). Internal damage will result from operating the com-
pressor in a deep vacuum.
CAUTION
!
Take necessary steps (place plywood over coil or use sling on motor) to prevent motor from
falling into condenser coil.
CAUTION
!
Do not remove wire harnesses from module unless you are grounded to the unit frame with a
static safe wrist strap.
CAUTION
!
Unplug all module connectors before per forming arc welding on any part of the container.
CAUTION
!
The unit must be OFF whenever a program ming card is inserted or removed from the control-
ler programming port.
CAUTION
!
Use care when cutting wire ties to avoid nicking or cutting wires.
CAUTION
!
Do not allow moisture to enter wire splice area as this may affect the sensor resistance.
