
Keep horizontal and vertical distances between the indoor and outdoor section as close
as possible to minimize refrigerant charge required. This will reduce system issues
related to oil management that can impair performance and jeopardize the
compressor’s lubrication.

保持室内和室外部分水平和垂直距离尽可能接近，可减少所需的制冷剂的充注。
这将减少与回油管理有关的麻烦。不然就可能降低性能，并危及压缩机的润滑系
统。

Provide a one-inch pitch in suction and liquid line toward the evaporator for every 3
meters of run to prevent any refrigerant that condenses in the suction line from flowing
to the compressor when the unit is off. These two lines can be routed together and
wrapped together, as long as the suction line is fully insulated as previously directed.

安排吸入管路和冷剂管时，朝向蒸发器端，每 3m 英尺长，应提供一英寸左右的
倾斜，以防止关机时管路中的回油吸入压缩机内。这两个管道可以缠在一起，只
要吸入管路按先前指示地做好保温材料处理。

Suction line riser traps are not required if the riser is properly sized to maintain
refrigerant velocity. Adding a trap will only increase pressure drop.

如果立管（RISER PIPE）的直径匹配适当，能保持制冷剂的流速， 吸入管路不
需要再设立立管弯肘。多增加一个立管弯肘，只会提高降压的幅度。

Prevent dips, sags, or other low spots that will trap refrigerant oil, which is an issue
especially with long horizontal runs. Use hard refrigerant copper for longer horizontal
runs to prevent potential oil return problems. (see sample piping chart on page 34)

安排长距离的水平管线时，应避免管线骤降，下垂，或其它低点聚集制冷剂油。
使用硬质铜管来防止潜在的回油问题。 （请参阅第 34 页上的示范管路图）

When sweat connections are made in the connecting lines, be sure that the inside of the
tubing is clean before installing the unit. Use a dry nitrogen bleed during brazing. Note
that compressor suction and discharge valves should be open to atmosphere no longer
than 15 minutes. Compressors with POE (polyolester) oil will quickly become
contaminated when opened to atmosphere. On any installation, the use of a suction
line filter, liquid line filter drier and moisture indicator is recommended. If the suction
line is larger than one-quarter inch, a vibration eliminator should be installed close to
the motor compressor in a horizontal parallel to the compressor, crankshaft or in a
vertical position 90 degrees to compressor crankshaft.

焊接铜管前，确保了管内是干净。钎焊过程中请保证铜管内干氮气流通。需要注
意的是， 正常气压下，压缩机吸入和排出阀门的开放不应该超过 15 分钟。压缩
机使用的 POE（多元醇酯）油剂在当向大气敞开时很快会被污染。所有的安装
过程，建议使用吸气管过滤器，液体管路干燥过滤器和水份指标器。如果吸入管
路比四分之一英寸大，振动消除器应安放在水平平行于压缩机，靠近曲轴位置，
或 将振动消除器安放在靠近压缩机电机曲轴垂直成 90 度角位置。
