1. The aforementioned piping connection sizes show the piping size to be connected on suction and discharge of the compressors by brazing.
2. The compressors are driving by two-pole motors mounted with the same shaft and with rotation of 2.880min-1 (2,880rpm) at 50Hz and 3,470min-1(3,470rpm) at 60Hz, at the rated votage.
3. Net weight invludes oil charge.
4. Power Supply
   A: 200V-50Hz, 200V-60Hz
   C: 380V-60Hz
   D: 380V-50Hz, 440V-60Hz
5. Models marked with are available.
   Models marked with are available on request or under development.
6. *Power supply of CE compliance model is only D: 380V-50Hz.
7. : Models marked with comply with CE standards at the customer side after setting up inverters in the compressors.
8. The performance data are based on the following conditions(temperature is based on central point) :

Refrigerant	R407C
Evaporationg Temperature	7.2 (45)
Condensing Temperature	54.4 (130)
Liquid Temperature	44.4 (112)
Entering Gas Temperature to Condenser	21.7 (71)
Ambient Temperature	35.0 (95)
Power Supply	Rated Voltage

Operating frequency range of Inverter compressor(G501DLV): 60-100Hz.
However, there is a limit to the pressure range when operating at 80-100Hz.
