1. When mounting a cross spacer directly on the inlet side of the lubricator, be
sure to use the AKM series check valve between the lubricator and cross
spacer.
2. Factory mounting of a cross spacer on the AC model is available as a
special order.
Caution on Mounting
Note) For pipe thread type: NPT only.
With the use of a pressure relief 3 port valve, pressure left in the
line can be easily exhausted.
