Warning
To avoid electric shock or personal injury, be sure to disconnect the freezer from power supply
before carrying out any repair or maintenance.
Make sure that no drug or suspended particles around the freezer will be breathed in at the
time of maintenance; otherwise they may result in health hazard.
Cleaning of the freezer
Clean the freezer once a month. Regular cleaning makes the freezer always brand-new.
Wipe off a little dust on the shell, inner compartments and all accessories of the freezer
with a dry cloth. If the freezer is very dirty, remove the dirt with a clean cloth and neutral
detergent, then wipe off the residual detergent with a wet cloth, and finally wipe the freezer
with a dry cloth. (Undiluted detergent may damage plastic parts. Please refer to the detergent
instructions for the dilution method.)
Never pour water onto the shell or into the preservation compartment of freezer; otherwise
the insulation layer may be damaged, resulting in faults.
The compressor and other mechanical parts are fully enclosed and require no lubrication.
Remove the frost or ice on the inner wall once a month.
Removal of frost on the inner wall
Frost usually forms on internal shelve, which may cause clearance between the cabinet body
and door seal and thus result in poor refrigerating effect. You may use the ice scraper provided
along with the freezer for defrosting. The following procedure is the method of defrosting
through emptying the freezer.
Note: Do not use any tool with sharp edges or corners such as knife or screwdriver for
defrosting.
1.
Take out all articles stored in the freezer and put them in another freezer or in a container
with freezing liquid carbon dioxide.
2.
Turn off the power switch.
3.
Open outer doors and leave them open for a period of time for defrosting.
4.
Wipe off water at the bottom of cabinet body with a dry cloth.
5.
After cleaning the cabinet body, turn on the freezer again.
6.
Put back the articles in the sufficiently cooled freezer.
Or you may use the “Defrost” key to defrost: after unlocking the keyboard, press and hold the
“Defrost” key for 5s, the compressor will stop running. This key doesn’t have automatic return
function. Therefore it is necessary to press and hold it for 5s again after defrosting ends, and
the compressor will resume normal running.
Battery maintenance
When the low-temperature freezer keeps working continuously, please test the battery
charge level every 15 days (please refer to the section of alarm test function on Page 12 for the
test method). In case of low battery charge level, make sure that the battery switch is on and
the battery is charged. When the battery has been charged for consecutive 7 days, please retest
the battery charge level. In normal conditions, the battery charge should be full. If low battery
charge level remains, it is recommended to replace the rechargeable battery.
The battery with power-down alarm function is a consumable item with 3-year service life.
If the battery has been used for more than 3 years, it may not act at the time of alarm. It is
recommended to replace the battery earlier. Please contact a Haier after-sales service
technician for the battery replacement.

If the freezer goes wrong, please check the following possible fault points before
asking for repair:
Failure to start
Is the connection of power supply normal? Is the main power switch on?
Is supply voltage too low?
Were many articles put in the freezer at a time?
Poor cooling
Is ambient temperature too high?
Are the doors closed tightly? (The frost between the cabinet body and the door
seal may reduce the sealing performance of doors)
Is the temperature setting correct?
Is the freezer away from direct sunlight?
Is the freezer close to a heat source?
Are the rubber hole cover and heat-insulating materials of test through-hole placed
correctly?
Were many uncooled items put in the freezer in past several hours? (In this case,
the problem is temporary. You may raise the set temperature and then gradually
reduce it after the freezer starts and stops normally in a short time.)
Noise
Is the freezer installed on solid ground?
Is the freezer’s shell contact with any object?
Has the freezer been leveled by adjusting its legs?
Is the freezer in low-temperature running state?
If the freezer’s internal temperature is relatively high due to many items in it,
sometime it make noises. The noise will lower with the reduction of temperature in
the preservation compartment.
Please check whether the noise is from the compressor (the compressor noise of
low-temperature equipment is louder than that of household appliances)
Knocking sound. It may be caused by rapid cooling and contraction of internal
components. In this case, please make the freezer’s temperature reduce gradually
without abrupt temperature reduction in a short time.

Warning
If the freezer is left unused for a long time in an unsupervised area, please keep
children away from it and make sure that its doors cannot be fully closed. Equipment
scrapping should be done by qualified persons. Be sure to remove the doors to avoid
accidents such as suffocation.
