Refrigeration Compressor

Model Number: 429 QV30H Key Specifications/Special Features: General requirements1. Compressor should be stored in a dry and drafty place.2. Compressor should not be tilted or inverted in storage,transportation and installation; collision should be avoided。3. Rubber plugs should not be pulled out from discharge tubebefore installation so as to avoid impurity and humidity. Duringthe installation, the rubber plugs of discharge tube should bepulled out at first, then the rubber plugs of process tube, andthe rubber plugs of process suction tube at last. The installationshould be completed within 10 min after that.4. The compressor’s ground connection should be reliablyconnected with that of the refrigeration appliance all the time.5. In order to keep a pressure balance in system, the interval ofoperation should not be less than 5 min.
6. The charging volume of refrigerant oil has been optimized by
our company. Don’t pour any oil out or into the compressor
randomly.
7. The accessories (e.g. Starter, thermal protection and more.) are nor
installed into the compressor wile delivery, but in the accessory
case. Be sure to select the corresponding starter and thermal
protection models rightly.
8. Match the proper evaporating temperatures according to the
low. Middle and high back pressure requirements. Pay attention
to the admitted ranges of voltage and frequency for the different
models.
9. Compressor cannot afford a high-voltage or starting/running
under vacuum condition. Checking insulation and compressive
resistance in vacuum is not allawed.
10. The process or suction tube of direct and semi-direct gas
compressor cannot be interchanged or it would be difficult to
guarantee the performance of compressor.
Special requirements for R134acompressor
1. Don’t keep the R134A compressor connect pipe open too long
better, no more than 10 minutes.
2. The vacuum pump and the charging system must only be
dedicated to R134a.
3. The organic substance non-compatible with R134a can’t be
used in the refrigeration system.
4. R134A refrigerant system should strictly control the moisture,
impurities, paraffin wax, such as silicone oil, and the content of
chloride ion
