Maintenance Tips

• Use Proper Pre‑Filtration: Always install a 1‑micron pre‑filter or water separator before the dryer to remove bulk moisture and debris — this protects internal components and is often required for warranty coverage.

• Check Automatic Drain Function: Verify the quick‑disconnect automatic condensate drain operates freely and isn’t clogged; proper drainage prevents water carryover and protects downstream lines.

• Clean Condenser & Panels: Periodically remove dust and debris from the condenser fins, ventilation areas, and evaporator surfaces to maintain heat rejection and drying performance.

• Monitor Electronic Controller: Regularly check temperature and dew point readings on the digital controller — unusual values may indicate airflow, refrigerant, or drain issues.

• Inspect Air Lines & Fittings: Look for leaks, loose connections, or damaged hoses at inlet/outlet points; tighten or replace components to maintain pressure and efficiency.

• Maintain Adequate Clearance: Provide good airflow around the unit by keeping at least 12″ clearance from walls and other equipment — this helps maintain condenser cooling and dryer efficiency.

• Power Down Before Service: Always shut off power and relieve system air pressure before cleaning, inspecting, or servicing internal parts for safety.
