3. The system fuel pressure will increase. As the
pressure builds up, no water will drip from the air
trap assembly drip line. At about 300 psig
(2 MPa), the bypass valve will cycle (close and
open).
NOTE - the bypass valve can be heard and
"——" is displayed while cycling.
4. As the pressure approaches 500 psig (3.45 MPa)
it may be necessary to adjust the PRESSURE
REGULATOR to obtain 500 psig.
5. At about 500 psig Pressure, the JFTOT will
automatically:
a. turn the heater power to ON at 80% initial
power,
b. record the time that the heater is turned on,
c. increase the temperature to the specified
Set Point,
d. begin counting down the Test Timer,
e. turn on the coolant pump.
WARNING HOT SURFACES - the heater test
section and lines are heated. Do not touch.
6. Remove the beaker from under the drip line and
replace with a clean beaker.
7. Adjust coolant flow so that the ball is in the
center of the green range.

8. After the temperature has stabilized at the
specified Set Point:
a. the bypass valve will automatically CLOSE,
b. the ∆P reading will be displayed.
9. After two minutes, the dP1 value will automati-
cally tare to zero (0 mmHg). A "(T)" will appear
in the lower right corner of the display indicating
the ∆P is tared.
10. The JFTOT will automatically record the ∆P. If
the ∆P exceeds 250mmHg, the JFTOT will open
the bypass valve.
11. Heater Tube Temperature profile: If specified,
see Heater Tube Temperature Profile in the
Operation Manual. This procedure can only be
followed after the heater has been on for more
than thirty minutes.
