Routine Maintenance Tasks (Monthly & Quarterly)
| Task | Frequency | Tools Needed |
|---|---|---|
| Clean air filter | Monthly | Brush or vacuum |
| Check drainage hose | Monthly | None |
| Wipe exterior panels & vents | Monthly | Damp cloth |
| Clean condenser & evaporator coils | Quarterly | Soft brush + air blower |
| Inspect casters and handles | Quarterly | Manual check |
Common Troubleshooting Issues & Fixes
1. No Cooling or Weak Airflow
Cause: Dirty filter, blocked vents
Fix: Clean filter, reposition unit for airflow
2. Excessive Noise
Cause: Loose fan blade or panel
Fix: Secure fan guard, check for obstructions
3. Water Leakage
Cause: Full drain pan or kinked hose
Fix: Empty water tank, straighten drainage hose

Cause: Tripped breaker, incorrect plug
Fix: Check power source, reset plug, ensure correct voltage
