Danger ! | Risk of explosion caused by welding or soldering work on closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant. | Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well-ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been drained. | |
Danger ! | Risk of death caused by falling from vehicle roof. Risk of injury to other persons caused by falling objects during work in roof area. | ||
| Protect air conditioning circuit and components from moisture when carrying out repair work | ||
| Procedure for a damaged or leaky air conditioning system | All models | |
| Notes on handling refrigerant R134a | ||
| Remove/install | ||
1 | Drain air conditioning system | MODEL 900 | |
MODEL 900.633/65 | |||

Insulation | |||
5 | Unscrew screw/bolt (5) and remove bracket (6) | ||
6 | Unscrew screw/bolt (7) and remove bracket (8) | ||
7 | Remove refrigerant line (S) | Installation: Mount refrigerant line (S) with new sealing rings (9). Replace sealing rings of refrigerant lines (R and T) on expansion valves (3 and 4) and on connecting point to air conditioner housing. | |
8 | Close off openings of refrigerant line (S), expansion valves (3 and 4) and connecting point to air conditioner housing using stop plugs | Record plug | |
9 | Replace fluid reservoir | ||
