CAUTIONS
1) Do not allow dirt or moisture
inside of the pipes.
• Keep the open ends of all pipes
capped until all pipes have been
connected.
• Pipe openings should face
horizontally or downwards if at all
possible.
2) When passing a pipe through an
opening in a wall, always keep
the end of the pipe capped.
3) Do not place pipes directly on
the ground. Do not scrape pipes
on the ground.
4) When deflashing (removing
burrs from) a pipe, point the
opening downwards so that no
scraps fall inside of the pipe.
5) When installing pipes on a rainy
day, always keep the ends of the
pipes capped.
