Connecting Viper Capillaries
Page 74
• Do not install capillaries or tubes that are stressed, nicked, kinked, or
otherwise damaged.
• Install capillaries and fittings only at the positions for which they are
intended.
This section describes how to connect Viper™ capillaries. All Viper flow
connections in the Vanquish system are designed to be finger-tight.
To connect Viper capillaries with knurls, follow these steps:
NOTICE
• Tighten or loosen Viper capillaries only with your fingers. Do not use
tools other than the knurl that comes with the capillary.
• To avoid damage to the capillary or connection, tighten and loosen
the Viper capillaries only when the system pressure is down to zero.
