Walk-in Freezer Manual Defrost

Steps

• Transfer product to backup freezer
  Move all product to backup walk-in or reach-in freezer maintaining ≤0°F. Use insulated covers if transfer takes >5 minutes. Document transfer log.
• Power off freezer
  Turn off compressor at disconnect. Apply LOTO if maintenance is electrical. Prop door open to allow air circulation.
• Place towels at door + drain
  Towels at threshold to absorb meltwater. Verify floor drain is clear and flowing. Empty drain pan if applicable.
• Allow ice to melt
  Typical defrost cycle: 2-4 hours depending on ice load. Do not chip large ice with sharp tools — coil damage risk. Use room-temperature water on stubborn buildup.
• Inspect and clean
  Once ice cleared: clean coil with manufacturer-recommended cleaner. Inspect door gasket for cracks. Verify drain still flows. Check thermometer calibration.
• Power back on and verify recovery
  Restore power. Close door. Monitor temperature drop — should reach 0°F within 4-6 hours empty. Verify no abnormal sounds.
• Return product when at temp
  Once freezer reaches ≤0°F sustained, move product back. Apply FIFO. Update equipment log with defrost date.
