Information
- Close all openings immediately upon starting work on the refrigerant circuit.
- Store all spare parts in a dry and closed-off area.
- Blast air-conditioning components with nitrogen before refitting.
- When fitting parts, do not remove plugs until shortly before installation. Do not remove the protective foil from the dryer until shortly before installation. The dryer absorbs moisture from the air and is then useless.
- Do not carry out repairs in the open in damp weather.
- Always replace the dryer after working on the refrigerant circuit.
- Moisture in the refrigerant circuit not only leads to poor cooling. Oversaturation can also cause the dryer to disintegrate and contaminate the air-conditioning system from inside. This may lead to expensive and complicated repairs.
- Evacuate the refrigerant circuit according to instructions.
- Use a pressure reducer when working with nitrogen.
