
The condensing unit needs to be hard-wired for the rated high voltage to be brought
to the field-installed contactor in enclosed plastic housing, from the load side (L1
& L2) of the contactor. Run a ground lead to be connected to the condensing unit
Ground lead at the compressor. The load side of the field installed contactor will
contain the power leads that are found under the condensing unit’s control box
cover.

冷凝器（机）需要进行硬连接，从负载侧（L1＆L2）接触口， 连接于额定高
电压的封闭式的塑料接线盒， 此接线盒须现场安装。地线应该连接到冷凝器
压缩机旁边的接地导线。冷凝器（机）的控制盒盖下 配有现场安装的接触器，
里面配有电源线接口。

Turn on power to the condensing unit 24 hours prior to system start-up to allow
crankcase heater to warm up compressor crankcase.

冷凝器的电源应提前 24 小时开启，让曲轴箱加热器预热压缩机曲轴箱。
Refrigerant Charging
充制冷剂
NOTE: The WGS40,.WGS75. WGS100 systems utilize a Headmaster control
valve to control head pressure at low ambient applications, therefore require a
specific initial charging procedure as outlined below. The wgs175 system does
not use this method of low ambient control (utilizes fan cycling), but can accept
initial charge into the liquid receiver port the same way and the system has the
same capacity.
注：WGS40，WGS75，WGS100 在低温环境下应用时，系统利用 HEADMASTER 控
制阀来控制压力头，因此初始充剂需要按照概述如下程序。
在 WGS175 系统不使用低温环境控制（利用风扇循环）这个方法，但是可以用同样的
方式在液体接收器端口接受初次充制剂，系统具有相同的容量。
