Installing Butt Fusion Heater Adapters
The heater body of this assembly is not coated. Coated butt fusion
heater plates are available for all butt fusion applications.
Butt fusion heater adapters are installed with eight Stainless Steel
Cap Screws.
Care should be taken to assure that the butt fusion heater
adapters are seated on the heater body, and that there is no
foreign matter trapped between these surfaces.
IMPORTANT: Do not over tighten the screws.
The surface of the butt fusion heater adapters are coated with an
antistick coating.

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.

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.
