1、为清洁及维修之用保留紧凑空间是非常重要的，一般要求恒温恒湿机四周距离墙壁等障碍600mm以上；
1. It is very important to reserve compact space for cleaning and maintenance. It is generally required that the constant temperature and humidity machine can be more than 600mm away from walls and other obstacles.
2、为了防止恒温恒湿机内部结霜，机组不应该暴露在温度低于处理空气露点的环境中，此外，如果机组安装在室外，应适当采取防护措施，需要防止雪雨和霜的进入；
2. In order to prevent frost in the constant temperature and constant humidity machine, the unit should not be exposed to the environment where the temperature is lower than the air dew point. In addition, if the unit is installed outside, the protection measures should be taken properly, and the entry of snow and rain and frost should be prevented.
3、恒温恒湿机安装处应通风，应避开强电磁、油烟、风沙及灰尘较大的场所，且应远离热源、腐蚀性气体，及存在或可能存在可燃性气体、蒸汽与空气混合行成的爆炸危险场所；
3, the installation of constant temperature and constant humidity machine should be ventilated, should avoid strong electromagnetic, oil smoke, wind sand and dust large place, and should be far away from heat source, corrosive gas, and exist or may exist or may be combustible gas, steam and air mixture of explosion dangerous place;
4、室外机组安装处需要敞开空间，以保证室外冷凝器散热良好。机组周围应设有排水沟或管道，用于冷凝水的排除；
4. Outdoor unit installation needs open space to ensure good heat dissipation for outdoor condensers. Drainage ditch or piping should be installed around the unit to remove condensate.
