Refrigerant Circuit Seals

• Replace the seals after removing.
• Before installing, coat the seals with refrigerant oil on a sponge.
• Make sure the seals are positioned correctly on the pipe or in the groove.
• Check the connections at the components and the refrigerant lines for damage. Even the smallest scratch can lead to a leak.
• Ensure cleanliness when working. Even the smallest contaminant, a hair for example, can cause a leak.
• Only install seals that are resistant to refrigerant R1234yf and the corresponding refrigerant oil. Refer to Electronic Parts Information (ETKA).
• Make sure the seal -1- is seated correctly in the groove -arrow- for the respective refrigerant line.
