4.4 Wiring接线
Warning: Connect the equipment to the correct power source. Incorrect voltage
can result in severe damage to the equipment.
警告：设备应连接到正确的电源。不正确的电压可能会导致严重损坏设备。
Danger: For personal safety and trouble-free operation, this unit must be
properly grounded before it is used. Failure to ground the equipment may cause
personal injury or damage to the equipment. Always conform to the local codes.

备可能会导致人身伤害或设备损坏。务必遵守当地的电气规范。不要使用已经超
负荷的电源线连接设备。
Refrigerator and freezer units use 10 or 16 amp power cords.
They are rated for 220/230 volts, AC, 50 Hz. Do not use
extension cords, and always use a three prong, grounded wall
outlet. Figure 1 shows the standard service cord plugs and wall
outlets used for Thermo Scientific refrigerators and freezers.冰箱

4.6 Door Seal门的密封
To check the door seal, complete the following steps:按照以下步骤检查门是否有效密封：
1. Open the door.打开门。
2. Insert a strip of paper (a couple of centimeters wide) between the door gasket and the
cabinet flange and close the door.在门的密封条和机柜法兰之间插入一张纸条（2厘米宽），
关闭门。
3. Slowly pull the paper strip from the outside. You should feel some resistance.慢慢地从外面抽
出纸条，应感觉到一定的阻力。
4. Repeat this test at 10cm intervals around the door. If the door does not seal properly, replace
the gasket.在门的周围每隔 10 厘米重复进行此试验，如果门密封不好，更换密封条。

9.0 Cleaning and Maintenance清洁和维护
9.1 Maintenance维护
•Condensers should be cleaned at least every six months. In heavy traffic areas,
condensers accumulate dirt more quickly. Failure to keep the condenser clean can result
in equipment warm-up or erratic temperatures.冷凝器至少每 6个月应清洗一次。在交通
繁忙区域，冷凝器藏污纳垢更快。如果不保持清洁冷凝器可导致设备太热或温度不稳定。
9.2 Cleaning清洁
•Wash the inside of the cabinet with a solution of one liter of warm water and thirty
milliliters of baking soda.用一公升温水加三十毫升的小苏打溶液清洁机柜内部。
•Wash the outside with a mild detergent such as dishwashing liquid. Do not use harsh or
abrasive cleaners.使用洗碗液等温和洗涤剂清洗外部。不要使用刺激性或腐蚀性清洁剂。
•When the condenser is dirty, clean it according to approved process.当冷凝器变脏，按
照核准的程序进行清洁。
