FIRST AID
An injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention immediately.
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, start-stop switches are turned off, and power supply
is disconnected.
Always work in pairs. Never work on the equipment alone.
In case of severe vibration or unusual noise, stop the unit and investigate.
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, disconnecting 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 modules in
both control boxes. Do not remove wire harness from the modules unless you are grounded to the unit frame with a
