Perform a vibration analysis profile. Schedule a bearing replacement if tolerances are exceeded. Possible Cause: Liquid refrigerant slugging the rotors.
Clean the filter chamber using a lint-free cloth. Lubricate the O-rings on the new filter cartridge with clean compressor oil. Insert the element firmly and torque the cover bolts to factory specifications in a star pattern. Step 5: Charge with Fresh Oil mcquay hsa screw compressor service manual best
The HSA’s male and female rotors are timed by gears. If you remove the rotors for bearing replacement and don’t follow the exact timing mark alignment procedure, the rotors will clash. The result: catastrophic seizure on start-up.
The manual provides exact tolerances for rotor clearances, bolt torques, and electrical specifications. Attempting to tighten a critical flange without knowing the exact torque value can cause leaks or structural damage. 2. Troubleshooting Diagnostic Trees : Hosts comprehensive PDFs for HSA, PFS, and
A generic “screw compressor” manual is useless here. The contains torque specs, clearance tables, oil type recommendations (typically McQuay OEM or an approved POE/MO blend), and step-by-step disassembly sequences that are unique to this family.
McQuay (now part of Daikin Industries) is renowned for engineering heavy-duty, high-performance HVAC equipment, with their HSA and HSS series screw compressors serving as the backbone of many commercial and industrial chiller systems. Keeping these complex systems running at peak efficiency requires an in-depth understanding of the manufacturer's guidelines. Possible Cause: Liquid refrigerant slugging the rotors

Before removing the old bearings, use a dial indicator to measure the existing axial movement of the rotors. Compare this data against the allowable limits in your specific HSA manual model chart. Step 4: Shaft Seal Replacement
