Removal and Replacement:
1. Remove wires from the control thermostat.
2. Remove the thermostat capillary bulb by firmly
pulling up on the capillary tube at the tank lid. This

control thermostat to the component bracket.
4. Slide the grommet to the line 7" above the bulb on
the new capillary tube.
5. Insert the capillary bulb through the hole in the
tank lid and press the grommet firmly and evenly
so that the groove in the grommet fits into the tank
lid.
6. Carefully bend the capillary tube so that the tube
and bulb inside the tank are in the vertical position.
NOTE - The capillary tube must be clear of any electri-
cal termination and not kinked.

trol thermostat to the component bracket.
