1. Installation and Environmentrequirement
improve air circulationheat dissipation：ensureSurrounding the equipmentThere is enoughSpace（Suggestion ≥50cm），Avoid blockagein and outWind vent,防止overheatingorheat dissipationbad.
environmenttemperature: Workambient temperatureusuallysuggestionIn 5~30Between ℃, too highOr too lowpossiblyaffect performance.
power supplystable: Usematchthe power supplyVoltage（Like 220V±10%）, GroundingreliableTo avoidandbigPower equipmentShared circuit.
horizontally placed：Equipment requiredStable placementTo avoidtiltorvibration， 防止compressordamage.

2.operationPrecautions
startpre-check：
confirmpipelineSecure connection，leak-free（especiallyCirculating mediumpipeline）.
Check cycleMedium（Like siliconOilWater)liquidIs the position correctInnormal range, insufficientTime requiredSupplement.
Temperature setting：
avoidsharptemperature differenceChange,It is recommended to5~10℃/Min'sratelifttemperature防止thermal shock.
High temperature（＞150℃）orLow temperature（＜40℃）Run time, need toPreheat in advance/precoolingequipment.
