7. MAINTENANCE
Maintenance frequency: To maintain the product, the power supply shall be cut off first.
In order to keep the product in the best working condition, it is recommended to carry out a
maintenance process every 6 months.
Freezer cleaning: Use non-corrosive neutral cleaner shall be used to clean the inner and outer
surfaces of the low-temperature freezer. After cleaning, dry it with a dry cloth.
Attention: Do not use water to wash the inner and outer surfaces to avoid affecting the
electrical insulating performance. Do not use boiled water, cleanser, acid, alkali, gasoline,
alcohol, benzene, caustic cleaners and bristle brush to clean freezer.
Use a soft brush or vacuum cleaner to remove dust from the condenser frequently to maintain
good condensation effect.
Rub a little talcum powder on the door seal often can prolong the service life of the sealing
strip.
When the low-temperature freezer runs for a long time, it is easy to accumulate frost at the
door seal, cabinet mouth and inner side wall of the freezer. Excessive frost layer will affect the
sealing performance and refrigeration performance. Please defrost regularly with a defroster
and wipe it clean with a dry cloth.
Use the non-corrosive neutral cleaner to clean the inner and outer surfaces of the low
temperature freezer. After cleaning, dry it with a dry cloth.
Machine shutdown: When the freezer is stopped, unplug the power plug and clean it
according to the above methods. After the natural drying process, cover it with plastic bags
and place it in a ventilated and clean place.
8. NON-FAULT SIGNS
The sound of flowing water: This is the sound of refrigerant flowing in the pipeline.
Compressor gets too hot: When the compressor works, its surface temperature can reach 70 ℃
~ 90 ℃.
When the low-temperature freezer works, both sides of the freezer (near the door) can be
slightly hot , which is due to the anti-exposure pipe.
Condensation on the door seal: In rainy and humid seasons or environments with high
humidity, condensation may appear on the outer surface of the freezer and the edge of the
door seal. Only need to dry it.
The temperature sometimes rises above the set value within the temperature control range:
This is because the system defrosts regularly and automatically recovers after defrosting.
