PACKING ASSEMBLY
INSTALLATION INSTRUCTIONS
1. Using thread sealant, thread the tapered end of
the union fitting into the thermostat manifold and
tighten.
2. Slide the jam nut over the capillary bulb with the
threaded end toward the end of the capillary
bulb.
3. Insert the capillary bulb through the union fitting
and into the thermostat manifold.
4. Place the rubber seal onto the capillary tube with
the split facing 90° from the top (see the
capillary union detail).
5. Fit the four brass disks onto the capillary tube,
with two of the brass disks on each side
of the rubber seal. Face the notch on one brass
disk toward the nearby brass disk to lock the
brass disks together. Then face the notches on
the brass disks 90° from the split in the rubber
seal.
NOTE: Lubricating the facing sides of the brass
disks will hold them together on the capillary
tube during installation.
6. Insert the rubber seal and brass disks into the
union fitting, hand tight.
7. Position the capillary bulb in the temperature
manifold as shown in the illustration. When
positioning the capillary bulb, do not allow the
bulb to compress against the support fitting.
8. Tighten the jam nut lightly, about 1-1/2 turns.
9. Examine the capillary union assembly for
leaks and tighten the union fitting just enough to
stop leaks. DO NOT over-tighten.
