Fusing 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.
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.
