Run - RFC SL Series Technical Manual

◎ Close to the electric control cabinet for easy wiring.
◎ The installation location and direction of the compressor are easy to observe the oil level and
daily maintenance.
◎ The strength of the installation position is sufficient, and resonance and noise are not easy to
occur.
◎ Reserve enough service space
8.1.3 Kaifeng pressure relief
When the compressor is connected to the system for piping, the compressor must be 0.
After the 5bar of nitrogen is discharged, the next installation work will be carried out.
8.1.4 Installation and piping
The welding part of the pipeline should withstand a pressure test of at least 30 bar, and
ensure that the system after welding is clean and dry.

8.2.1 Precautions before operation
Compressor inspection
◎ Location of refrigeration oil.
◎ Temperature and heating time of refrigeration oil.
◎ Is the suction and exhaust valve open?
◎ Whether the capillary is twisted or damaged
Electrical system inspection
◎ The voltage and frequency of the compressor are correct.
◎ Control circuit voltage value.
◎ Whether the motor terminal block to ground is above 10MQ.
◎ The motor terminal and grounding wire are fixed correctly.
◎ Check whether the setting values of switches, sensors and controllers are correct.
Precautions for vacuuming
◎ Use a large diameter nozzle as much as possible to vacuumize.
◎ The high and low pressure sides are evacuated at the same time.
◎ When vacuuming in winter or low temperature areas, increase the surrounding
temperature as much as possible to ensure the vacuuming effect.
