Refrigerant R134a handling precautions
It is important to maintain dedicated HFC service equipment and
parts:
• Refrigeration gauges
• Service lines / Fittings
• Vacuum Pump
• Charging equipment
• Driers
• Compressors
• Temperature / Pressure chart
HFC (R134a) refrigeration systems require special service proce-
dures because of the highly hygroscopic (moisture sensitive) poly-
olester (POE) compressor oil:
• The system (especially compressor) must only be open for the
very minimum time (to prevent moisture ingression). All parts
required for servicing must be at hand - before the system is
opened, and there should be no interruption until the system is
on the vacuum pump (or hermetically sealed).
• The system must not be open for longer than 20 minutes max.
• The drier must be replaced every time the system is opened.
• Clean work practices are essential.
• SKOPE recommend brazing the system closed after service - as
valves are prone to leak due to the nature of R134a.
Important:
Every time the refrigeration system is opened the drier MUST be
replaced.
