Quick Start
1.
Pre-heat the heating jacket to 10°F (6°C) above the desired test temperature.
a.
Thermometer in jacket.
b.
Thermostat light turns on when target temperature is reached.
2.
O-rings:
a.
Inspect o-rings and install in cell body, cell caps and on valve stems.
b.
Coat all cell o-rings with Silicone Stopcock Grease, #153-55.
3. Cell Assembly:
a.
Install inlet cell cap, being sure the arrows on lid and cell body align.
b.
Set screws – Ensure the set screw points are sharp. Tighten the set
screws completely.
c. Install the valve stem on the inlet side of cell body.
4. Invert cell and pour sample into the cell leaving at least 0.6 inches (1.5 cm)
void space to allow for heat expansion.
a.
Do not spill fluid on the o-ring groove.
5.
Place a pre-soaked ceramic filter of your choice on top of the o-ring.
6. Push the outlet cell cap into the cell, making sure the arrows align.
a.
Valve stem initially open to facilitate insertion.
b.
Tighten set screws
c. Close (tighten) the outlet valve stem. Both valve stems are closed and
the cell is sealed.

retaining pin.
10.
Connect the back pressure assembly and lock in place with the retaining pin.
11.
Puncture CO
2
bulbs - Adjust inlet/back pressure regulators to desired
back pressure.
12.
Open (loosen) the inlet (top) valve stem a ½ turn to pressurize the cell.
13. Heat for one hour. The thermometer should register at the target
temperature within an hour. Total heat up time should not to exceed 1
hour.
14. After the hour heat up time, increase pressure on inlet (top) pressure unit
to 500 psi over the back pressure.
