注意：温度过低时，防止冷冻介质在设备中结冰损坏冷冻机一、安装要求：1、冷冻机安装前请选择地基平稳，四周空旷，畅通及避免腐蚀、污染、日晒、雨淋，方便安装维修之场所；2、水冷式冷冻机，根据冷冻机制冷量选用匹配的冷却水塔。

冷水机管路配管，请根据机身管路尺寸进行安装，切勿将冷却水管尺寸缩小，这样会引起高压超载，影响制冷效果及增加耗电量；3、风冷式冷冻机，请必须安装在距离墙壁一米以上空间位置，以免造成散热不良引起高压过载影响制冷效果及增加耗电量。

注：（1）电源负载及接地部分，请依照相关法规施工！（2）新安装的冷冻机冷冻水管必须包保温层！二、开机准备首次运转冷冻机必须先检查下列事项是否正确：1、电源电压及相数是否符合型号规格，请对照铭牌所示。

[注：三相电源相位线分别为R、S、T，中性线（零线）N，接地导线为双色线用E表示；机内设有错、缺相保护器，当在第一次开机时出现电源故障报警时，可能出现错相保护，可将相线任意两相对换接妥后合上开关即可；单相电源相线为L，中线为N，地线为E。

]2、检查冷冻水管及冷却循环水管是否接通管路，并保持阀门打开；（请参考安装示意图）3、先将冷冻水箱加满水或其它冷冻介质后方可启动水泵；（注：请根据要求来配用冷冻介质）4、水冷式检查冷却水泵运行方向及水塔风机是否逆转（如水泵是三相，逆转须将电源相位线中任意二相对换，接妥后再把开关合上即可）。

本使用安装说明书并非质量保证书，对印刷错误的更正, 所述信息谬误的勘误，以及产品的改进，均由广州特域机电有限公司随时做出解释，恕不预先通知，修正内容将编入再版使用安装说明书中。

一、使用注意事项1、请确保电源插座接触良好并且地线可靠接地！虽然冷水机的平均工作电流不大，但是其瞬时工作电流有时高达6~10安培（AC110V电源机型瞬时工作电流有时高达10~15安培)。

2、请确保冷水机的工作电压稳定、正常！由于制冷压缩机对电源电压比较敏感，我公司标准产品的正常工作电压为200~250V（110V机型为100~130V）。
