b. Procurement and delivery of new AC Compressors that meets or exceeds the specifications of the existing Carrier, Model 30RAN022-5(compressor A1, Model: SM115S3CA, 200-230v 3ph ~ 60Hz, LRA 265, R22 refrigerant/ compressor A2, Model SM160T3CB, 200-230v 3ph ~60 Hz, LRA 298, R22 refrigerant). Proposed compressor unit specifications shall be submitted to the COR for Contracting Officer approval.

c. Identify a replacement refrigerant compatible with existing system. Options include R-407C, R-421A, R-438A, R-448A, and R-449. 2. Verify the existing lubricant is compatible or needs replacement with the newly selected “drop-in” refrigerant. Check the systems expansion devices and controls for adjustments. Ensure proper evacuation of R-22 and leak testing before charging the new refrigerant.

d. Safe and environmentally compliant decommissioning and disconnection of the existing compressors, including refrigerant recovery and disposal in accordance with all federal, state, and local regulations.

e. Removal and disposal of the old compressor units from the premises.

f. Installation of the new AC Compressor Units, including all necessary mechanical, electrical, and plumbing connections, modifications to existing piping/conduit as required, and structural support if necessary.

g. Start-up, testing, and balancing of the new compressors to ensure optimal performance and integration with the existing HVAC system.

h. Commissioning of the new unit, including performance verification and a comprehensive system check.

i. Provision of all necessary documentation, including shop drawings, equipment specifications, operation and maintenance (O&M) manuals, as-built drawings, and warranty information.

j. Post-installation cleanup and removal of all debris from the work site.

k. There is also an optional bid in place for the replacement of a pair of tandem scroll compressors circuit (Copeland model: ZZ32M3-TWC-271, 200-230v, R22 refrigerant) within a McQuay Model AGZ050BS12-ER10; as well as the replacement of the condenser coil for the circuit and a leak check and repair of the entire circuit described in the optional bid.
