Maintenance
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.
NOTICE:
Install heater plates only when the heater is cool.
IMPORTANT:
Do not over tighten the bolts.
The surface of the butt fusion heater plates are coated with an
antistick coating. Damaged or worn butt plates must be replaced.

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.
