Installation
Ground the System
Warning
»
The system, when operated with non-polar solvents such as
hexane, methylene chloride, etc., can build up a high static
electricity charge, which in certain conditions can be dangerous.
To eliminate any risk of a static discharge, the systems and
ancillary containers must be grounded before use as described
below. Failure to follow these grounding instructions may result
in equipment damage, personal injury, or death.
»
A trained person must verify that the system and ancillary
containers are grounded before each run. Nominal resistance
must be below 5 Ohm between ground and each metal point in
the system.
The pre-wired grounding kit that is supplied with the system
includes a complete wiring harness assembly (see Figure 14)
and a pair of fraction collection assemblies (see Figure 15).
Figure 14.The wiring harness assembly included in the grounding kit.
Figure 15. The fraction collection assembly for the Flash 75 system (left)
and the Flash 150 system (right).
Note:
All the alligator clips must be connected to metal
fittings/objects, not to the plastic tubing.
Note:
Before installing the grounding kit, ensure that the system
tubing has been installed in accordance with the instructions in
“Attach the Inert Gas Supply and Solvent Lines” on page 10.
1. Connect the first alligator clip (item 1 in Figure 16) to a
grounded point, such as a metal cold water pipe.
Note:
To be an acceptable grounding point, the entire run of
pipe must be made of metal. Have a qualified person, such
as an electrician, verify that the point is grounded before
operating the system.
2. Connect the next alligator clip (item 2 in Figure 16) to the
on/off valve on the top of the solvent reservoir, at the point
where the metal tubing connector is located.
3. Connect the next alligator clip (item 3 in Figure 16) to the
three-way valve on the top of the sample injection module,
at the point where the metal tubing connector is located.
4. Connect the next alligator clip (item 4 in Figure 16) to the
bottom of the sample injection module, at the point where
the metal tubing connector is located.
5. Connect the next alligator clip (item 5 in Figure 16) to the
three-way valve on the top of the radial compression module,
at the point where the metal tubing connector is located.
6. Connect the last alligator clip (item 6 in Figure 16) to the
metal fitting on the bottom of the radial compression
module.
7. Connect the fraction collection assembly tube (item 7
in Figure 16) to the fitting on the bottom of the radial
compression module as described in “Fitting with Nut and
Ferrules” on page 10.
Note:
The grounding kit contains two fraction collection
assemblies. The one with the smaller nozzle and a tube with
an outer diameter of 1/8" is for Flash 75 and the one with the
larger nozzle and a tube with an outer diameter of 1/4" is for
Flash 150; see Figure 15.
8. Wrap the uninsulated wire (item 8 in Figure 16) that connects
to the last alligator clip (item 6 in Figure 16) around the
fraction collection tube (item 7 in Figure 16) and then
securely tighten the terminal ring on the uninsulated wire
(item 9 in Figure 16) between the two hex nuts on the
fraction collection nozzle (item 10 in Figure 16).
9. Verify that the system is grounded using an electrical
multimeter (DVM). Nominal resistance must be below 5 Ohm
between ground and each metal point in the system.
