SERVICE INSTRUCTIONS Recommended Service Procedures SKOPE recommend the SKOPE Cyclone® demountability and exchangeability philosophy, which in essence means: The customer must not be inconvenienced during system maintenance. In the unlikely event of Refrigeration failure, an exchange unit is simply swapped in a matter of minutes. There is no cabinet down time or unloading product.

Finally, pinch-off the gauge process lines (or remove line piercing valves) and braze the system closed. SKOPE recommend against leaving service valves in the system as these are prone to leak (and are open to abuse). Perform a final system leak test.
Page 41
• 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.
