Several general requirements as below
Compressor should be stored in a dry and drafty place
Compressor should not be tilted or inverted in storage, transportation and installation; Collision should be avoided.
Rubber plugs should not be pulled out from discharge tube before installation so as to avoid impurity and humidity. During the installation, the rubber plugs of discharge tube should be pulled out at first, then the rubber plugs of process tube, and the rubber plugs of process suction tube at last. The installation should be completed within 10 min after that.
The accessories (eg. Starter, thermal protection etc. ) are nor installed into the compressor while delivery, but in the accessory case. Be sure to select the corresponding starter and thermal protection models rightly.
Starting device is PTC
Frequency only for 50HZ
Voltage application from 220 to 240V
R290 compressor
Efficient application in commercial refrigerator
Strong load capacity
