3.1—Lubricate the O-rings
DO NOT USE VASELINE
The tank O-ring—

—
seals the control valve to
the tank, and the pilot O-
ring—
Img 4
—seals around
the riser tube. Verify they
are present and free from
nicks or kinks. Use a
silicone lubricant or
vegetable oil to both O-
rings.
DO NOT USE
PETROLEUM BASED
LUBRICANTS!
Please note
that the pilot O-ring is up
inside the control head and you will usually have to reach up inside to feel it.
It is
very secure inside the head and almost impossible for it to come out. It is also a good
idea to verify that the riser tube fits snugly into the pilot hole and that the O-ring
seals around it.
3.2—Inspect and install top distributor basket if applicable
Depending on system
configuration your system
may include a top
distributor basket—

.
If your system includes one
it is recommended that you
use it. If you do not have
one then it is not needed. If
you do have one the larger
end will fit inside the
bottom of your control
valve, with the smaller end
sliding over the riser tube
pointing down into the tank—

. Please note that
locking tabs hold it in place so a fair amount of force is needed to install or remove it.
