Installing Butt Fusion Heater Plates
The heater body of this assembly is not coated. Coated butt fusion heater
plates are available for all butt fusion applications.
Butt fusion heater plates are installed with eight stainless steel cap screws.
Care should be taken to assure that the butt fusion heater plates 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 plates 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.
