Lid Window Replacement
When the Lid window needs to be replaced, it
should be reassembled as follow:
1. Using the Lid Window Carrier Tool with Tom-
my Bar (1). Unscrew the Window Clamping
Ring (2) that clamps the 32mm Diameter
Quartz Tapered Edge Lid Window (3) in place.
2. Remove the quartz window and clean the
clamp thread and the surface of the heater.
3. Place a new quartz window into position,
with the smaller diameter facing the clamp.
4. Screw the clamp loosely back into position. As
it is being hand tightened, move the window
gently from side to side to make sure that the
quartz window is centralise and sit in the right
position.
5. Using the tool, tighten the clamping ring. It
may be necessary to use the tool’s Tommy Bar,
but do not use excessive force.
Note: The gap setting may need to be recali-
brated when one or both of the Lid and/or
Base windows have been replaced. Refer to
Setting the Sensors - Zero, Lid and Reference,
page 28 for more information
