• Install the condenser on the existing concrete slab and secure it in accordance with Miami-Dade County HVHZ requirements.

C. System Integration & Commissioning

• Brazing and System Preparation:

o Braze copper refrigerant lines, purge with nitrogen, and perform a proper vacuum using a micron gauge to meet ASHRAE 15 & 34 standards.

• Refrigerant Balancing and System Startup:

o Balance refrigerant levels as needed per manufacturer specifications.

o Conduct system startup and ensure the system operates efficiently.

• Zoning System Installation:

o Connect the system to the existing 24V zoning damper.

o Install a compatible zoning system to maintain temperature balance throughout the designated areas.

D. Protective Measures & Warranty

• Coastal Protective Coating:

o Apply a coastal protective coating to the condenser coil and cabinet to prevent corrosion and ensure durability in the high-humidity, salt-air environment of Biscayne National Park.
