3. Installation – 5-Minute Retrofit

1. Remove old fan — undo 2 M3 screws; unplug 2-way Molex.
2. Clean surface — IPA wipe to remove dust and oil; allow 30 s to dry.
3. Mount RAH2260B1-C — push into 60 mm cut-out until snap-ring clicks; stick EVA pad.
4. Connect plug — red +24 V, black 0 V, lock Molex until click.
5. Test — run car on inspection; fan must start within 3 s and stop 3 min after stop.

4. Daily Operation – What the Fan Actually Does

• Circulates 22 L/min — prevents condensation and CO₂ build-up
• Runs only when car moves — saves 0.15 A × 3 min = 0.0075 Ah per trip
• Ball-bearing design eliminates squeaks; <18 dB(A) at 1 m
• IP54 gasket resists brake-dust ingress; UV-stabilised for outdoor shafts
• Temperature range -25 °C to +80 °C — outdoor scenic lifts included

5. Replacement Cycle & Preventive Maintenance

• High-traffic office (>1,000 trips day⁻¹) – blow dust every 3 months, replace fan every 4 years
• Residential tower (300–600 trips day⁻¹) – inspect annually, replace every 6 years
• Low-rise freight (≤200 trips day⁻¹) – inspect every 18 months, replace every 8 years

• Airflow <18 L/min (anemometer test)
• Noise >25 dB(A) at 1 m during run
• Bearing temperature >65 °C after 10 min run
• Current >0.2 A or <0.1 A (multimeter test)
• UV discoloration >50 % surface area

6. Extending Life – 3 Pro Tips

1. Keep filter mesh clean; brake-dust blocks blades and increases noise
2. Never over-grease—ball-bearing is sealed for life; excess attracts grit
3. Store on lanyard; prevents loss and ground strikes during service
