De-gas the system
Draw the plunger of the syringe just past the 10ml mark
Install the syringe kickstand so that it cups the plunger and supports it
in the drawn-out position; the syringe will brace against the flange on
the plunger and the barrel
Leave the syringe in this position for about an hour
Remove the kickstand, while keeping the syringe in place
With everything still attached, draw the plunger of the syringe just past
the 10ml mark again
Very gently pump the plunger up and down approximately 10 times,
until no bubbles come out of the system after drawing the plunger
.

Clean up and reassemble
Remove the refill adaptor
Remove excess oil from the pressure port with a tissue or swab
Once cleaned, install the lower mesh insulator disk with the recess
facing up
Place the nickel-copper mesh in the recess of the lower mesh insulator
disk
Place the upper lower mesh insulator disk on top of the lower mesh
insulator disk and nickel-copper mesh assembly
Open the split on the retaining ring and ease its middle into the sensor
end-cap recession
Hold the retaining ring in place with one finger and feed the the rest of
the ring into the sensor end-cap recession
Bubbles will be coming out of the system through the oil into
the syringe, drawn into the rarefied air. The rate of bubbles
coming out should quickly start to reduce. If it is not
happening, tighten the syringe to the refill adaptor and
tighten the four cap screws.
The plunger will drop back, almost to the surface of the oil,
due to low pressure inside the syringe.
