Welding of Units or Containers
Electric welding can cause serious damage to electronic circuits when performed on any portion of the
refrigeration unit, container or container chassis with the refrigeration unit attached. It is necessary to
ensure that welding currents are not allowed to flow through the electronic circuits of the unit. The
following statements must be rigidly adhered to when servicing these units to avoid damage or
destruction.
•
Disconnect all power to the refrigeration unit.
•
Disconnect all quick-disconnect wire harnesses from the back of the controller.
•
Disconnect all wire harnesses from the Remote Monitor Modem (RMM).
•
Switch all of the electrical circuit breakers in the control box to the Off position.
•
Weld unit and/or container per normal welding procedures. Keep ground return electrode as close to
the area to be welded as practical. This will reduce the likelihood of stray welding currents passing
through any electrical or electronic circuits.
•
The unit power cables, wiring and circuit breakers must be restored to their normal condition when
the welding operation is completed.
Removing Refrigerant Properly
Use a refrigerant recovery process that prevents or absolutely minimizes refrigerant escaping to the
atmosphere. Fluorocarbon refrigerants are classified as safe refrigerants when proper tools and
procedures are used. Certain precautions must be observed when handling them or servicing a unit in
which they are used.
Fluorocarbon refrigerants evaporate rapidly, freezing anything they contact when exposed to the
atmosphere in the liquid state. In the event of frost bite, attempt to protect the frozen area from further
injury, warm the affected area rapidly, and maintain respiration.
•
Eyes:
For contact with liquid, immediately flush eyes with large amounts of water and get prompt
medical attention.
•
Skin:
Flush area with large amounts of lukewarm water. Do not apply heat. Remove contaminated
clothing and shoes. Wrap burns with dry, sterile, bulky dressing to protect from infection/injury. Get
medical attention. Wash contaminated clothing before reuse.
•
Inhalation:
Move victim to fresh air and use CPR or mouth-to-mouth ventilation, if necessary. Stay
with victim until arrival of emergency medical personnel.
