What should I do if refrigeration fuel is low?
Arrange an authorized refill before operation is threatened. Notify dispatch immediately if the unit could stop before a safe fueling opportunity.
How often should I check reefer operation?
Follow the carrier and shipment monitoring procedure, including checks at safe stops. Report changing temperature, alarms, or fuel concerns promptly.
Why does airflow matter in a reefer?
Blocked circulation can prevent uniform temperature control. Follow loading requirements and report blocked ducts, damaged chutes, or unsuitable placement.
What if the shipper loads warm product?
Document readings using the required procedure and contact dispatch before accepting responsibility. A reefer is not guaranteed to rapidly cool improperly prepared cargo.
Should I turn the reefer off while doors are open?
Follow the product, unit, and facility instructions. Door-open procedures differ; confirm the correct method rather than improvising.
What is a reefer trailer?
It is a temperature-controlled trailer with refrigeration equipment. Safe operation requires attention to unit settings, fuel, airflow, cleanliness, and shipment instructions.
Should I pre-cool a reefer before loading?
Follow the shipper’s written instructions and cargo requirements. Verify the specified temperature and unit mode rather than applying one rule to every product.
What is continuous versus start-stop reefer operation?
The modes manage unit operation differently. Use the shipment’s required mode; do not switch merely to save fuel.
Does the setpoint prove cargo temperature?
No. Setpoint, air temperature, and actual product temperature are different. Follow required checks and document discrepancies before accepting the load.
What if the reefer displays an alarm?
Record the code, contact qualified support, and follow approved instructions. Protect cargo without disabling warnings or guessing at repairs.
