用
HFC
（如
R404A
）制冷剂时，仅可使用
POE
油，在使用此类制冷剂时切莫混合其它的润滑油。当
POE
油
用于
HCFC
（如
R22
）制冷剂时也许可以混合少量其它润滑油。
Use only POE oil with HFC refrigerants. Do NOT mix POE oil with other oils when using HFC
refrigerants (eg R404A). Small quantities of other oil types may be mixed with POE oil when
using HCFC refrigerants (eg R22).

冷凝器
Condenser
：
冷凝器建议每三个月进行一次清洁。
The condenser is recommended every three months to be clean.
系统运行
System Running
：
每六个月应进行系统检查，包括制冷剂充注量检查及电气连接检查。
System is recommended to be checked every six months, including refrigerant charge
inspection and electrical connection check.

曲轴箱加热器
Compressor Crankcase heater
曲轴箱加热器将曲轴箱维持在一个适合的温度，能防止制冷剂发生迁移。曲轴箱加热器的效率是通过测量
油温来检查的，油温应该比环境温度高至少 10K。理想的油温应控制在
50℃~70℃
之间。在各种环境温度下，应
经常检查保证有适当的油温。
Crankcase heater maintain the crankcase in a suitable temperature, prevent the occurrence of
refrigerant migration. The efficiency of the crankcase heater is checked by measuring the oil
temperature. Oil temperature should be higher than the ambient temperature for at least 10K. The
expected temperature would be between
50
℃
~70
℃
. Recommend to check oil temperature regular,
for ensure that oil is in appropriate temperature.

机组接线
Unit Electrical Connection
请参阅（电气图），图为壁挂室外型机组的推荐接线方式。图中机组的接线方式已完全反映出来，而其它
连接和总的系统连接则需安装者自行设计。
Attached Wiring Schematic is recommended to electrical connection spacing (For detail, Please
Refer to Wiring Schematic). If other connections are required for the installation of the system,
please connect contractor or dealer

旋锁阀注意事项
Roto-Lock Valve Attention
：
在旋转机组中相应的旋锁阀的阀杆以前
,
压紧螺母必须先松开
,
以确保密封圈不会因为阀杆的转动而受到损坏
,
在旋转阀杆以后
,
用扭矩扳手以
13
扭矩将压紧螺母锁紧
,
防止制冷剂泄漏。具体数据如下：
Before turning valve rod of R/L valve, the gland nut must be released. Make sure that the
sealing ring is not damaged by the rotation of the valve rod. After turning valve rod, lock the gland
nut with a torque wrench for 13 torque, to prevent leakage of refrigerant. The detail is below
