WARNING
• Keep hands away from the pipe ends and the
openings of the valve when attempting to insert
pipe ends into the valve.
Failure to follow this instruction could result in
personal injury.
5a. ASSEMBLE JOINT: Assemble the joint by inserting the marked
HDPE pipe end into each opening of the valve . The HDPE pipe ends
must be inserted into the valve until (1) contact with the seat occurs
AND (2) the marks on the HDPE pipe ends meets the edge of the valve
body, as shown above .
Inspect
5b. INSPECT SEAT: Each pipe end must be inserted into the valve until
contact with the seat occurs, as shown above . A visual check is required
to ensure that the seat meets the pipe ends .
5c. REMOVE ONLY THE SPACER BOLTS: There is one spacer bolt on
each bolt pad to maintain spacing between the bolt pads during shipping
and assembly . After inserting pipe, remove only the spacer bolts and the
attached warning tags before tightening the four nuts in step 6 .
CAUTION
• Spacer bolts are designed to keep the valve’s housings at the
proper spacing during installation of the pipe ends.
• These spacer bolts must be removed prior to tightening the hex
nuts to bring the bolt pads into metal-to-metal contact. The
bolts will prevent proper tightening of the valve housings.
Failure to follow these instructions will cause damage to the valve
components. This may result in joint leakage or property damage,
and could void the product warranty.
NOTE:
Do NOT discard the spacer bolts . Reinstall the spacer bolts
to finger-tight after valve installation is complete . If the valve must be
removed from the system, the spacer bolts will be necessary to separate
housings and maintain spacing (dimension "C", as defined in the
dimension tables found on pages 7–10) between the bolt pads during
storage, shipping, and reinstallation .
