Installation & Service Tips
-
Handle with care to avoid damaging the fins; use fin combs to straighten any bends before startup.
-
Verify cabinet sizing and refrigeration line connections match the coil dimensions; check indoor-unit clearances per the OEM installation manual.
-
Before brazing or leak checking, cap off all ports and pressurize with dry nitrogen to prevent oxidation and moisture ingress.
-
After installation, clean the coil with a mild coil cleaner and rinse thoroughly; ensure the condensate pan and drain line remain clear.
-
Balance airflow across the new coil by adjusting blower speeds and verifying static pressures to OEM specifications.
