058 Installation Procedure Wrap marking tape perpendicular to the pipe shaft, put a cutting section surface on the entire circumference with a permanent marker and cut using a manual saw by avoiding misalignment. Chamfer the end surface of insertion port with a file, etc. Mark a gauge line on the insertion port pipe. Wipe o f f t h e s o i l a n d s a n d attached on the rubber ring and groove and the socket inner face with a cloth. If the rubber ring is removed for cleaning, put it into the groove by squeezing into a heart shape. Check for twisting and misalignment. Wipe off the soil and sand attached on the insertion port outer side with a cloth. Apply AV lubricant to inner face of rubber ring and insertion port (especially the chamfered tip area) evenly.

Make sure to avoid the shaft center misalignment and never hammer in by using a hammer. After connection, check the entire circumference using a check gauge to see if the rubber ring is in a proper condition.

Be cautious especially in Winter. �A Store away from direct sunlight and avoid unevenness on the pipe platform. Do not use a transparent sheet because it has no effect and gives a negative influence. �B Do not hammer in when connecting pipes. �C For rubber ring connection, make sure to check the rubber fitting and inspect for twisting and direction. Be cautious of attachment of soil/sand, muddy water, etc. �D Do not clean the rubber ring groove with a slipper y item such as lubricant. �E If you notice spring water before backfilling, drain, put sand in a couple of layers and tamper sufficiently. �F Sufficiently fill the area around pipes to avoid any cavity. �G The groove bottom shall be sand, in principle. For weak ground, additionally lay crushed stones underneath or improve the soil quality. Do not have stones and bedrock hit pipes directly. �H Follow the procedure below in the diagram for backfilling. Piping Precautions In the case of the size 100 Notes: 1. Dotted line shows the position immediately after inserting soil and sand. Notes: 2. Solid line shows the position after tampering the soil and sand.
