Working with high-pressure gas and rotating machinery carries inherent risks. Always follow the Lockout/Tagout (LOTO) procedures detailed in the manual before performing any service. Ensure that the system is fully depressurized and that the refrigerant has been safely recovered before opening the compressor casing. howden xrv 127 manual
Piping and Cleanliness: All suction and discharge piping must be thoroughly cleaned. Debris left in the pipes can cause catastrophic damage to the rotors. The manual recommends installing a temporary suction strainer during the commissioning phase.
Complete dismantling of the compressor. Replace all radial and thrust bearings, replace the mechanical shaft seal, inspect rotor profiles, and renew all elastomeric O-rings and gaskets. Critical Reassembly Clearances

by altering the discharge port size. This ensures internal compression matches external system pressure, significantly reducing energy loss. Stepless Capacity Control:
Features an internal slide valve that adjusts the built-in volume ratio while running. This matches the internal compression ratio with the system operating pressures, eliminating over-compression or under-compression losses.
