Figure I YC-55L (It can be used as reference for YC-55EL, YC-75L, YC-75EL)
®The transportation and movement of equipment is realized by casters.
®A special person shall be responsible for checking and recording the running status of the equipment every
day (record and check once every 2-4 hours). In case of failure or shutdown, the temperature in the
Refrigerator will rise. If it cannot be repaired in a short time, please take out the stored items and transfer
them to a place that meets the temperature requirements for storage to avoid damage to the items.
®Before putting items into the equipment, it shall be confirmed in advance whether the temperature range of
the equipment meets the temperature requirement of the items, so as to avoid damage to stored items due
to the difference between the settable temperature of the equipment and the required temperature of the
items. Please pay attention not to block the air outlet and air inlet when putting items into the equipment.
®Due to the refrigeration inertia, there is a certain difference between the actual display temperature and the
set temperature of the equipment, which is a normal phenomenon.
®The equipment is an item storage equipment, which cannot be used for routine production operations. It is
strictly forbidden to put too many items which are relatively hot into the equipment at one time, otherwise
the compressor will run for a long time, and be burned due to high temperature. Items must be put in
batches, so as to ensure that the Refrigerator is cooled step by step until the temperature required for
storing items is reached.
®Electrical appliances without production license shall not be used inside the equipment.
®Do not change the set temperature frequently in a short time, otherwise the expected setting effect may not
be achieved due to the large temperature inertia; Ensure that there is a certain air circulation space around
the cabinet when putting in items, especially do not block the temperature sensor in the cabinet (for
collecting the temperature of the cabinet), otherwise it will affect the stability and accurate control of the
temperature in the cabinet!
®Items shall not be placed directly at the bottom of the Refrigerator, but on the bottom shelf, otherwise the
refrigeration effect of the equipment will be affected.
®When putting in items, if the moisture content of the items is too much or too little, it will affect the humidity
change in the cabinet, so it is best to keep the items sealed; The humidity of the working environment will
affect the change of humidity in the cabinet, especially if the door is opened too frequently and the door is
not closed properly.
Notes:
Warning: Children are not allowed to play with this equipment as a game prop, otherwise the injury
or loss caused therefrom will be at their own risk.

them to a place that meets the temperature requirements for storage to avoid damage to the items.
®Before putting items into the equipment, it shall be confirmed in advance whether the temperature range of
the equipment meets the temperature requirement of the items, so as to avoid damage to stored items due
to the difference between the settable temperature of the equipment and the required temperature of the
items. Please pay attention not to block the air outlet and air inlet when putting items into the equipment.
®Due to the refrigeration inertia, there is a certain difference between the actual display temperature and the
set temperature of the equipment, which is a normal phenomenon.
®The equipment is an item storage equipment, which cannot be used for routine production operations. It is
strictly forbidden to put too many items which are relatively hot into the equipment at one time, otherwise
the compressor will run for a long time, and be burned due to high temperature. Items must be put in
batches, so as to ensure that the Refrigerator is cooled step by step until the temperature required for
storing items is reached.
®Electrical appliances without production license shall not be used inside the equipment.
®Do not change the set temperature frequently in a short time, otherwise the expected setting effect may not
be achieved due to the large temperature inertia; Ensure that there is a certain air circulation space around
the cabinet when putting in items, especially do not block the temperature sensor in the cabinet (for
collecting the temperature of the cabinet), otherwise it will affect the stability and accurate control of the
temperature in the cabinet!
®Items shall not be placed directly at the bottom of the Refrigerator, but on the bottom shelf, otherwise the
refrigeration effect of the equipment will be affected.
®When putting in items, if the moisture content of the items is too much or too little, it will affect the humidity
change in the cabinet, so it is best to keep the items sealed; The humidity of the working environment will
affect the change of humidity in the cabinet, especially if the door is opened too frequently and the door is
not closed properly.
Notes:
Warning: Children are not allowed to play with this equipment as a game prop, otherwise the injury
or loss caused therefrom will be at their own risk.
