Inserting Heater
The heater is not explosion proof. Operation
of heater in an explosive atmosphere without
necessary safety precautions will result in
serious injury or death.
If operating in an explosive atmosphere, the heater should
be brought up to temperature in a safe environment, then
unplugged before entering the explosive atmosphere for fusion.
Use a clean non-synthetic cloth to clean the butt fusion heater
surfaces.
Check the heater with a pyrometer to make sure it is at the right
temperature.
Raise the fitting off the pipe enough to insert the heater.
Insert the heater and lower the fitting down on top of the
heater. Support the heater during heating cycle, making sure
the melt pattern is established in the proper area. If the heater
handle is not supported, the heater may shift down, causing an
improper melt.
Follow the pipe and fitting manufacturer's time, temperature
and pressure recommendations for the heating cycle.

Removing Heater
Pull the drive screw forward to clear the split nut and pull upward
on the drive screw while giving the heater handle a downward
snap action with your hand. This will break the bond between the
heater and the fitting, so the fitting can be raised and the heater
easily removed.
When using high volume tapping/punch tees it will probably
require two people. One person handle the heater and the other
to disengage drive screw and pull fitting away from pipe.
Inspect for complete melt pattern. If melt pattern is not complete,
finish the fusion and decommission the fitting.
