Description
The Hand Village Heat Pump Replacement project calls for the supply, installation, and commissioning of 28 new heat‑pump units on a multifamily building roof. The work includes full brazed refrigerant connections, conversion of existing three‑phase power to single‑phase, and coordination with the agency to address water‑heater interference. All equipment must be Rheem or Ruud models using R‑32 refrigerant, and units will be mounted on an EPDM‑membrane roof with standard curbs.
• 28 heat‑pump units total (21 × 2.5‑ton, 7 × 3‑ton)
• Required brands: Rheem or Ruud; refrigerant R‑32 only (no Pro‑Press fittings)
• Electrical: single‑phase (208/230 V) – contractor must convert existing three‑phase supplies
• Roof type: EPDM membrane, requiring appropriate mounting and waterproofing measures
• Additional tasks: water‑heater removal/re‑install by APSU as needed, hot‑work permits and fire‑watch for brazing, post‑award site verification visit.
