Who needs this International 9000 HVAC manual
A/C technicians and heavy-truck shops use this section to service compressors, evaporators and heater cores and to recharge systems safely. It is written for trained professionals with recovery equipment.
The section stresses that refrigerant must be recovered before opening any A/C component, and that R-134a should never be pressurised with air. Use approved recovery and recycling equipment, follow the oil-fill guidelines when replacing parts, and verify airflow at each duct after reassembling the Blend-Air unit. Component location tables and the torque chart help you get the heater core, blower and actuators back in without leaks or noise.
