1. Never disconnect any part of the air conditioner refrigerant circuit until the refrigerant has been removed by a qualified refrigeration technician.
2. If the air conditioner parts prevent any other repair work, it is permissible to remove their fastening and move them to the side as far as the flexibility of the connections allows, but do not disconnect the hoses. If there is still not enough space to perform the work, then before disconnecting and removing the parts, it is necessary to completely discharge the system. After completing the work, charge the system.
3. Periodically check the condition of the condenser, remove dirt and insects from it with a stream of water from a hose or compressed air.
4. Check the tension of the compressor drive belt periodically. The belt deflection in the middle of its longest branch should be 10.0 mm. If adjustment is necessary, loosen the pulley nut, then turn the bracket adjusting bolt to the desired angle and tighten the pulley nut again.
