To perform a pre-trip inspection, start by checking the unit for visible damage or leaks. Inspect the condenser and evaporator coils for debris and clean them if necessary. Ensure all electrical connections are secure, and check the oil level in the compressor. Finally, verify that the temperature control settings are correct for the intended load.
If the unit is not cooling properly, first check the air filters and coils for blockages. Ensure that the doors and seals are intact and not allowing warm air to enter. Verify that the temperature settings are correct. If issues persist, inspect the refrigerant levels and contact a qualified technician for further assessment.
Regular maintenance should be performed every 3 months or as specified in the unit's manual. This includes checking refrigerant levels, inspecting electrical connections, cleaning filters, and ensuring all components are functioning correctly.
