Maintenance
Clean Heater Surfaces
The heater faces must be kept clean and free of any plastic build up or
contamination.
Before each fusion joint the heater surfaces must be wiped with a clean,
non-synthetic cloth.
NOTICE:
Do not use an abrasive pad or steel wool. Use a non-synthetic
cloth that won't damage surfaces.

are seated on the heater body, and that there is no foreign matter
trapped between these surfaces.

The surface of the butt fusion heater plates are coated with an
antistick coating.

Adjusting Heater Temperature
Turn knob to desired temperature. Measure the heater surface
temperature with a pyrometer. Any variance must be corrected to the
pyrometer reading.
Loosen setscrew in the knob. Turn knob to point to the same
temperature as the pyrometer. Tighten setscrew in the knob.
Turn knob to desired temperature. Allow heater to stabilize at the new
temperature (5 to 10 minutes) after adjusting.
The thermometer on the heater body indicates internal temperature and
should be used as a reference only.
