Before Installation

• Confirm the core fits the AHU section with clearance for seals
• Verify duct connections align with the core ports
• Plan condensate drainage for sensible cores in cooling mode

During Installation

• Seal all interfaces to prevent airstream leakage
• Support the core to avoid stress on the frame
• For rotary wheels, align the drive and check the seals

Controls

Wire summer bypass, frost protection, and alarms per the manual. Mis-wired frost control is the top cause of winter failure.

After Installation

Balance airflow, commission, and record baseline temperatures and pressure drop for future troubleshooting.
