Operation
Completing the Test
1. When the test is complete, press and hold the “RUN/HOLD” button on
the temperature controller until the “Run” and “Hold” lights are both off.
2. Turn off the “Heat” and “15 VDC” switches and turn on the “Cool”
switch. Make sure the water supply is turned on.
3. As the test cell cools, watch the pressure carefully. As long as the tem-
perature is over 180°F (82.2°C), make sure the pressure is at least
1,000 PSI (6,900 kPa).
4. Once the test cell has cooled, turn off the“Cool” and “Motor” switches.
5. Open the Pressure Release valve (counter-clockwise) all the way.
Always release the pressure very slowly to prevent damage to the
equipment.
6. Slowly turn the “Oil Reservoir Valve” to “Vent”.
7. Open the “Air To Cylinder” valve (counter-clockwise). Air pressure will
force the oil back into the reservoir. You will hear a hissing sound as air
is released. When the hissing sound stops, close the valve (clockwise).
8. Carefully unscrew and remove the thermocouple.
Keep a rag or paper towel handy in case extra oil leaks from the cell.
9. Unscrew and remove the cell cap. Remove the potentiometer and slur-
ry cup.
10. Return the cell cap to the test cell to prevent dust and other material
from entering the cell. Close all valves and turn off all switches.
