Pump Compartment
This compartment is located on the right
side of the Pinnacle PCX. It contains the
reagent pump(s), gas manifold, and
electronics for the heated reactor and
valves(figure 2-11).
The only time you will need to access
this panel is for pump piston seal
replacement. All other times, qualified
personnel should make any repairs.
The Pump, Valves, and Heated Reactor
are described in other sections.
Here you will see the Piston Wash feature
for the reagent pumps. The Piston wash
is a 1/4” OD tubing connected to the
back chamber of the syringe.
Gas Manifold
The “Gas Inlet” fitting is a 1/4-28 fitting
located on the back panel of the Pinnacle PCX
(reference fig 2-15). The inert gas source is
connected via a 1/8” OD Air Barrier tubing,
and the pressure is regulated to 5psi before
pressurizing the reagent reservoirs.
The gas regulator requires an input pressure
of 45–75 psi (3–5 bar) to function properly.
The manifold has a safety relief valve that opens
at about 10 psi to prevent dangerous over-
pressurizing of the reagent reservoirs.
