Maintenance

WARNING

Always cut off the power supply before any repair and maintenance of the

equipment to prevent electric shocks or personnel injuries.

Make sure that drugs or suspended particles from the surrounding envi-

ronment will not be inhaled during equipment maintenance. Otherwise it

may cause harm to human health.

CAUTION

Do not spray water directly on the ULT freezer, in case the insulation per-

formance of electrical components decreases and metal parts get rusty.

Do not clean the ULT freezer with hot water, corrosive detergent, or organ-

ic solvent, etc.

Do not put heavy objects on top of the equipment in case it deforms under

pressure.

Cleaning of ULT freezer

The ULT freezer should be cleaned once a month. Regular cleaning keeps 

the ULT freezer a brand-new appearance.

Wipe the dust off the ULT freezer's shell, inner chamber, and all accesso-

ries with a dry cloth. If the ULT freezer is dirty, wipe it with a cleaning cloth 

soaked with a neutral detergent to remove the dirt and wipe off the residu-

al detergent with a wet cloth. Then, wipe it with a dry cloth again.

Do not pour water onto the ULT freezer shell or into the ULT freezer. Oth-

erwise, it may damage the electrical insulation, leading to a failure.

The compressor and other mechanical parts are completely sealed and 

do not need lubrication.

Clean the frost or ice on the inner wall and the condenser filter screen 

once a month.

Cleaning of condenser filter screen

The filter screen shall be cleaned once a month under normal use. If the filter 

screen is blocked, the refrigeration effect of the ULT freezer will be affect-

ed and the service life of the product will be reduced. Please clean the filter 

screen as follows. Do not move the sensor wire.

1. Remove the front bottom hood and the filter screen.
2. Clean the filter screen with water.

3. Blow off the dust on the condenser with compressed air.

4. After the filter screen is dried, put it back to its original position and install

the hood.

Notes:    The configuration of different product models is different, which is 

subject to the physical object.
