Fuse the Pipe
NOTICE:
Failure to follow pipe manufacturer's fusion procedures
may result in a bad joint.
After following the pipe manufacturer's suggested heating
procedure:
A) Shift carriage control valve to the open position.
B) Move the carriage to the right just enough to engage the stripper bar.
Quickly remove the heater.
C) Shift carriage control valve to close carriage. Quickly move
the carriage to the left, bringing the pipe ends together under the
pipe manufacturer's recommended pressure. It is necessary
to continually actuate pump lever to maintain fusion pressure
until the fused joint solidifies.
Allow joint to cool under pressure according to pipe
manufacturer's recommendation or appropriate joining standard.
D) The carriage pressure may continue to bleed off slightly
during the cool-down period. This can be overcome by actuating
the pump lever periodically to maintain proper carriage
pressure, being careful not to over pressure the joint.
