For efficient filtration of the oil that lubricates the bearings in the compressor, an oil filter cartridge has been inserted in the compressor block.įurthermore, the compressor contains a built-in non-return valve, preventing the compressor from running backwards whenever the power to the driving motor is disconnected. The suction filter housing also has a built-in compressor protection valve which - controlled by a pilot valve - safeguards the compressor against any unwanted high compression pressures. The compressor is fitted with a large built-in suction filter, which effectively prevents dirt particles from the refrigeration plant from being led with the suction gas into the compressor. The driving rotor is fitted with a shaft. The rotors are designed for both male drive and female drive. The axial forces are partly relieved by means of the rotating balance pistons mounted on the rotors. The two rotors are equipped with 4 lobes (male rotor) and 6 lobes (female rotor), respectively, executed with asymmetric profile according to SRM licence.Īs indicated on the spare parts drawing at the end of this manual, the rotors at the suction end are fitted with slide bearings, whereas the bearing at the discharge end consists of a combined bearing set with slide bearings, absorbing the radial load, and ball bearings, absorbing the axial forces.

The reset involves entering a code while in r-12 mode, then removing all hoses and switching the switch to R-134a mode and entering another code. I called tech support and they walked me through a process that resets the machine. If the tank (R-12 or R134a) does not have at least 10 pounds of refrigerant in the tank before you change to another refrigerant, the machine will stay in the clearing process. The machine got stuck in Clr or (Clearing) while changing from R-12 to R-134a. I had a similar problem with a Robinair 17800b.
