TYPICAL PIPING DIAGRAMS
The Model 62 vacuum breaker can be installed
vertically or horizontally. However, installing the
vacuum breaker horizontally results in fouling of
the seating surface, which prevents tight sealing.
The life of the o-ring may be increased by
installing the vacuum breaker in a standpipe
where temperatures are lower.
