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. condenser cleaning : clean the dust on the condenser regularly to avoid affecting the cooling effect (cleaning method: first open the screws of the ventilation hood or front hood and use a brush to gently brush away the dust on the surface of the condenser).
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.
® The integrated overload protecter within our products is programmed to shut down the power supply automatically with respect to short circuit and/or system overload for the sake of protecting the entire system and crucial components such as the compressor.
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 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; The equipment should be connected to power supply regularly (generally once a month) and turn on the power switch and battery switch for a period of time to complete the charging if it’s not used for a long time,and each charging time should not be less than 24 hours; Power switch and battery switch should be turned off in time after discontinuation of equipment, otherwise it will cause battery capacity loss and in serious cases battery permanent damage could happen; The main power switch must be turned off during a long-term power outage or during transportation, otherwise longterm discharge causes power loss in battery and even permanent damage to the battery, and the display is abnormal after re-energizing; The battery is 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 Turn off the power switch and pull out the power plug from the outlet; 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); 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; Use a screwdriver to remove the fastening screws on the battery fixing plate and take out the battery; 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.
