In the event of a diaphragm rupture, vapor will
enter the pump head center section. To avoid fire
and explosion, always replace air in the center
section with CO
2
.
Prior to using the pump, it is necessary to replace all
air in the center section with CO
2
. The pump head
center section drives the pumping with the CO
2
gas
charge. To ensure no air is present, use the following
method.
1.
At the CO
2
port (E), close the center section vent
valve.
2.
At the CO
2
port (E), open the CO
2
supply line
valve and adjust the CO
2
regulator to set the CO
2
to the maximum pressure setting of 150 psi.
3.
Close the CO
2
supply line valve and open the
center section vent valve.
4.
Repeat steps 1–3 a second time to purge any
remaining air.
5.
Repeat steps 1 & 2 to place the pump in
operational state.
The maximum pumping pressure will be a few psi
less than the internal CO
2
pressure setting.

Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure is
relieved manually. To help prevent serious injury
from pressurized vapor, follow the Pressure Relief
Procedure when you stop pumping for an extended
period of time, and before you clean, check, or
service the equipment.
1.
Remove electric power from the system.
2.
Vent all LP-Gas vapor from the pump and hoses
according to extractor system instructions.
3.
Close the shutoff valve on the CO
2
cylinder.
4.
On CO
2
port (E), open the pump CO
2
bleed valve
and CO
2
supply valve.
NOTE:
NOTE:
NOTE: In the event of a diaphragm rupture,
LP-Gas may be present in the pump center
section. Always vent all LP-Gas according to
extractor system instructions.
5.
If performing repairs, remove CO
2
regulator and
tank from the pump prior to performing the work.
