Important Hints - Klarstein 10031434 Bedienungsanleitung

Important Hints

• DO not use mineral oil on flared part.
• Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
• Never use piping which had been used for previous installations. Only use parts which are delivered with the
unit.
• Do never install a drier to this R410A unit in order to guarantee its lifetime.
• The drying material may dissolve and damage the system.
• Incomplete flaring may cause refrigerant gas leakage.
