Removal and Replacement:

4. Slide the grommet to the line 4.5" above the bulb

tank lid and press the grommet firmly and evenly
so that the groove in the grommet fits into the
tank lid.

and bulb inside the tank are in the vertical posi-
tion.
NOTE - The capillary tube must be clear of any electri-
cal termination and not kinked.
