ecostore 1 Door Digital Refrigerator 670lt (-2/+10)

Visual inspection: check all external and internal surfaces (doors, handles, runners, feet) for pitting corrosion, white rust, or oxidation spots. Verify protective passivation layer intact. Inspect stainless steel panel welds for crevice corrosion. Check marine feet for deterioration.

Pressure test system for leaks using proper marine-grade equipment. Verify refrigerant charge weight against datasheet specifications (typically 75-145g depending on model). Check all connections, valve seats, and compressor seals for signs of leakage or oil residue. Test system pressure at operational temperature.

Power on unit and verify digital display illumination and temperature readout accuracy with calibrated thermometer. Test RS485 data port connection to HACCP system. Verify alarm settings trigger correctly at temperature limits. Check Bluetooth connectivity (where applicable). Inspect circuit board for salt corrosion or moisture.

Check exterior cabinet for dents/cracks that expose insulation. Listen for hissing sounds indicating foam degradation. Measure interior/exterior temperature differential under load to verify cooling power against specifications (e.g., 1045W for ecostore 2-door freezer). Inspect interior surfaces and underside of cabinet for mold, discoloration, or moisture stains.

Test door opening/closing cycle 5-10 times; verify self-closing mechanism engages smoothly. Inspect triple-chamber magnetic gasket for visible cracks, loss of magnetic force, or deterioration. Check gasket contact surface along entire door frame for warping or gaps. Verify door locks securely and latch holds under pressure. Look for salt residue around door seals.
