Electric Defrosting

D series air cooler can be used with different refrigeration capacity of the compressed condensingunit for different temperature of the cold storage, as refrigeration equipment.

1.DL typeis practical for cold storage with a temperature of about 0°C. as the cold storage of fresh eggs or vegetables.

2.DD series is suitable for cold storagewith the temperature of -18°C, as the cold storage of frozen food such as meat and fish.

3.DJ series issuitable for cold storage with storage temperature in or below -25 °C for fast freezing of fresh meat or fish products.

1.Inspect the power connection and equipment appearance before startup,

2.ensuring no damage or loose wires.

3.Switch on the power, set target storage temperature and automatic defrost cycle on the control panel.

4.The unit will run automatically for cooling and timed electric defrosting.

5.Keep the evaporator ventilated and clean; avoid random disassembly.

A:Check defrost time, voltage, and electric heating elements; ensure no damage or poor contact.

Q:Why does frost build up quickly?

A:May be caused by frequent door opening, low temperature, or excessive humidity. Adjust parameters and seal the cabinet.

Q:What to do if the fan does not run after defrost?

A:Check delay setting, fan motor, wiring, and temperature sensor; reset controller if needed.

Q:How often to defrost?

A:Set according to usage: 2–6 cycles per day is typical. Adjust based on frost thickness.

Q:How to maintain?

A:Regularly clean coils, check heating elements, drain pipe, and wiring to ensure safe operation.
