connected in 4 directions.
Take off the knockout part of the pipe cover through
which pipes or wires will pass through the base plate.
• Detach the pipe cover and tap on the knockout section
a few times with the shank of a screwdriver. A
knockout hole can easily be punched.
• After punching out the knockout hole, remove burrs
from the hole and then install the supplied protective
bush and guard material around the passage hole to
protect wires and pipes.
Be sure to attach the pipe covers after pipes have
been connected. Cut the slits under the pipe covers to
facilitate the installation.
After connecting the pipes, be sure to mount the pipe
