7.1 Equipment Maintenance
Defrosting: The equipment will automatically defrost during the working process for the convenience of use.
Cleaning and maintenance: The equipment should be cleaned and maintained regularly (for safety, please unplug
the power plug), and the inner and outer surfaces of the cabinet should be wiped with a warm, damp soft cloth.
Notes:
®
Do not sprinkle water directly on the cabinet, lest the insulation performance of electrical components decrease and
metal parts rust.
®
Do not use hot water, corrosive detergent or organic solvent to clean the cabinet
®
Do not place heavy objects on top of the equipment, as the equipment may deform under pressure.
7.2 Equipment Discontinuation
Deactivation: If the equipment is stored in an unsupervised area for a long time and not used, the power supply
should be cut off and the inner and outer surfaces of the cabinet should be cleaned with a warm, damp soft cloth,
aired and sealed. The equipment must be locked to ensure that children cannot open the cabinet door.
Scrapping: When the equipment reaches the end of its service life, it should be scrapped and must be handed over
to a qualified professional recycling agency for disposal per local regulations. Non-professionals are not allowed to
disassemble and break down the equipment without authorization. The scrapped equipment should be placed in a
designated area inaccessible to children to avoid danger.
7.3 Maintenance, Replacement, and Recovery of Rechargeable Batteries
Battery installation position: top of the cabinet and bottom inside the electrical box.
1. Battery maintenance
①
In order to prolong the service life of the battery and avoid the product being left unused for a long time, the
product must be operated for more than 24 hours every month to facilitate charging.
②
When the equipment is not used for a long time, it should be connected to the working power regularly (generally
once a month), and the power lock switch should be turned on so that the equipment can run for a period of time to
complete charging, and each charging time should be no less than 24 hours;
③
When the working power supply is interrupted, the power lock switch of the equipment shall be turned off in time,
otherwise it will cause power loss in battery and even permanent damage to the battery in severe cases;
④
The main power switch must be turned off during a long-term power outage or during transportation, otherwise
long-term discharge causes power loss in battery and even permanent damage to the battery, and the display is
abnormal after re-energizing;
⑤
The battery is a consumable, with a service life of about 2-3 years. If the battery is used improperly, such as
power loss or reaching the end of battery life, it will cause a low battery alarm (refrigeration is not affected, but there
is an alarm failure and influence to the use function of the printer, please contact the after-sales staff of local
distributors for replacement).
2. Battery replacement and recovery
①
Turn off the power switch and pull out the power plug from the outlet;
②
Remove the screws on the electrical box with a screwdriver. (Note: There are high-voltage electrical components
in the electrical box, therefore before opening, turn off the power supply, unplug the power plug and turn off the
power lock switch of the refrigerator, and the electrical box can only be opened by qualified engineers or
maintenance personnel).
③
Pull out the battery connecting cable; (Before unplugging the battery fixing cable, pay attention to the
cathode/anode of the battery and the sequence of the connecting cables, so as to prevent burning down the control
system due to installation of the new battery with cathode/anode reversed. Generally, the red wire is connected to
the cathode, and the black wire is connected to the anode.
④
Use a screwdriver to remove the fastening screws on the battery fixing plate and take out the battery;
⑤
The battery model BT-12M1. 3AT (12V) is suitable for (YC-55L/EL, YC-75L/EL), and the rest of the products are
BT-12M4. 0AC (12V4. 0AH);
⑥
For a replaced battery that can be recycled, please contact the local battery recycling agency.
Tips:
In order to effectively ensure that the battery replacement meets the requirements of the control system and
avoid the influence of improper operation on the system, please contact our after-sales personnel for replacement
or guidance.
