Leak Checking and Evacuation Process 泄漏检查和方气过程
WARNING
ALL COMPONENTS CHARGED WITH DRY AIR MUST BE EVACUATED
BEFORE CHARGING WITH REFRIGERANT
充制冷剂前，
使用过干燥气体的所有部 件都必须经过充分释放

Purge the dry air charge from the unit by opening the liquid line shut-off valve or
removing the liquid line outlet fitting or plug, whichever is applicable for your
particular unit. Connect the suction and liquid lines to the unit.

根据你设备的不同，通过打开液体管道截止阀门或除去液体管线出口阀门，清除
使用过的干燥空体。将吸入管和液体管线连接到机器上。

Pressurize and leak test the entire system including the condensing unit, evaporator and
all connecting tubing, fittings, and brazed joints using the intended operating
refrigerant for leak testing. A pressure equal to the low side test pressure marked on the
unit nameplate is recommended for leak testing. Repair any leaks found. Connect a
good vacuum pump to both the low and high side evacuation valves (if provided) with
copper tube or high vacuum tube (three-eighths inch inside diameter minimum) and
draw a deep vacuum of at least 15pp microns. Do not use the motor compressor to pull
a vacuum and do not operate the motor compressor in a vacuum. Break the vacuum
with nitrogen.

使用指定的制冷剂对整个系统，包括冷凝机组，蒸发器和所有连接管道，管件和
钎焊接头等，加压和实施泄漏测试。渗漏测试的压力等于机组铭牌上建议的低压
侧最大允许压力指数测试。补上发现的漏洞。使用好的真空泵连接到低侧和高侧
的排气阀（如果提供的话）与铜管或高真空管（最小内径八分之三英寸），真空
抽至 15PP 微米深的真空。不要使用电动压缩机做抽真空，电机压缩机在真空中
不要启动。使用氮气破开真空状态。

Evacuate the system to hold at 500 microns and break the vacuum with refrigerant.
Remove the vacuum pump. The system is now ready for charging. Charge the system
with the correct amount of refrigerant and mark the amount, with a ballpoint pen, in
the space provided on the unit nameplate.

排空系统保持在 500 微米的压力， 使用制冷剂中断真空状态。卸下真空泵。该
系统此时可以充制冷剂。用圆珠笔在机组铭牌上的空间，记录充好制冷剂的正确
数量。
NOTE: When charging through the suction service valve the refrigerant should
be charged in vapor form. NEVER CHARGE IN LIQUID FORM. Refrigerant
should always be charged through a dryer. Charging in liquid form may damage
the valve plate assembly as well as scrub the oil out of the compressor
bearings
