Pre-Installation Checks
- Verify the packing list, separate units by system, and never mix models with different specs.
- Inspect each functional section, pipe orientations, coil row counts and fin density against documentation.
- Confirm fan and motor parameters, airflow direction, and check for damaged panels or bent fins.
- Build a concrete base with level error under 5 mm and size it 100 mm larger than the unit on each side.
Assembly Steps
Align the base coordinates and level, then assemble sections square and tightly. For units with a spray section, install it first from the pump base, then build outward; its doors must not leak. For coil sections, keep the condensate drain clear and fit a water seal to block air leakage. Where the fan ships separately, set the empty casing first, then load fan and motor. Connections use bolted closed-cell rubber or clip joints per the manual.
Final Verification
Field-assembled units must pass an air-leakage test to confirm sealing and safe operation.
