“HF SERIES” PURIFICATION APPLIANCE 3
Introduction
Introduction
This L-Factor appliance is a “special application” compressed gas purifying system designed to operate at high
pressures. It is intended to treat once purified gas a second time (second stage purification) in order to achieve
ultrahigh levels of purity. This is a “once through” type appliance utilizing Disposable Cartridges. The appliance, or
hardware, operates in concert with the cartridges, or software, which are the core of the system.
With the compressed gas entering the device, it is preconditioned by an optional Mechanical Filter and then flows
evenly through a series of Cartridge Holders. These towers contain the Disposable Cartridges which can be
configured according to customer needs and applications. It is of paramount iportance that the user not vary from the
cartridge models specified on the appliance. Always change all cartridges at the same time, as a set.
On some models, a cartridge change indicating device (Eyeball Indicator) is fixed at the inlet to the tower chain in order
to tap off a sample of the gas for constant evaluation. The standard device will indicate RH of the gas by coloremetric
change as viewed through a window placed at the topside of the “Eyeball”. Replacement elements are available for a
range of RH as well as other kinds and levels of substances.
In the case of compressed air, a minimum level of grade “E” (according to the CGA) is expected to enter the appliance.
The gas now follows a path through a final Micronic Filter towards discharge at the Priority Valve and into the outlet
piping.
The standard Appliance is supported on an angle plate chassis that facilitates fixing to a permanent vertical
foundation or hanging from another equipment. There is a Pressure Gauge at the discharge manifold in addition to a
system Drainage Valve. Some models are supported by an optional freestanding chassis which also supports
electronic monitoring units.
Special attention has been paid to all materials and treatments in order to guard the ability of this equipment to achieve
the high gas purities required of it. Carefully follow the instructions set forth in this manual and use added precautions
to avoid internal contamination.
It is of paramount importance that the user does not exceed the operating limitations set forth for this appliance. Do
Not exceed pressure, flow rate, or temperature ratings.

Service Of Cartridges
Installation of Cartridges
PRECAUTIONS: Always depressurize and remove electrical source from this appliance prior to performing any
service. Do Not direct compressed gases at bodily openings, eyes, or skin. Do Not attempt to regenerate disposable
cartridges. Do Not rotate cartridges - always replace all cartridges as a set, otherwise contaminants could be
reintroduced to gas stream.
CARTRIDGE SERVICE INTERVALS: This appliance can only process the amount of gas rated on the nameplate of
the appliance as well as on the front page of this manual. Cartridges must be changed at their maximum calculated life
or every six months, whichever comes first. Many variables will contribute to the capability of this equipment. It is our
recommendation that a reliable monitor be placed at the discharge point in order to gauge the humidity level of the gas
in determining the appropriate change of cartridges. Otherwise, approximated cartridge change can be calculated
with the following formula.
This formula is based on average operating conditions for appliance. Low pressures or high temperatures will reduce useful cartridge life.

in operating hours
TOOLS REQUIRED: Spanner wrench (available from
manufacturer) or 5/8" closed end wrench, non-hydrocarbon
grease with applicator, graphite paste, leak detector pliers
and a flashlight.
PROCEDURE: Refer to "IDENTIFICATION" page of this
manual for location of components. Turn system "OFF" and
isolate appliance from gas stream by means of isolation
valves (optional). Vent compressed air from system by means
of system pressure release valve. Monitor gauges to be
certain that appliance is empty.
Remove cylinder head(s) from cartridge holder(s) as
illustrated. You should be able to turn the cylinder head with
moderate pressure. If force is required, STOP and recheck
appliance pressure to verify that it is empty.
Lift spent cartridge from cylinder using the lifting bail provided
at top of cartridge.
Using flashlight CAREFULLY inspect interior of cylinder for
extraneous matter and any wear exhibited on the cylinder
walls. Any deterioration may be cause for replacement.
Remove cartridges from packaging, one at a time, holding
them with the outer wrapper used as a "glove" in order to
prevent contamination by handling. Remove lower protective
seal from mating end of cartridge. Suspending cartridge by
lifting bail, lower new cartridge into place. NEVER drop
cartridge into cylinder. Apply slight pressure to seat cartridge
onto mating stem/port of cylinder.

PROCEDURE (continued) Using applicator, lubricate cylinder head O-
Ring(s) with non-hydrocarbon grease. Also, apply a light film of graphite
paste to the threads using care not to contaminate interior of cylinder
(non-hydrocarbon grease may be used in place of the graphite paste).
Note that the cylinder foot should be serviced periodically in this same
manner. Refer to the maintenance schedule for recommendations
Reassemble in reverse order using the spanner wrench. If binding is
encountered STOP and check for obstructions, cartridge position, and
thread clearance. DO NOT over tighten cylinder ends. Tighten until dust
cover or lip touches cylinder and then back out slightly.
Open the inlet isolation valve to permit gas flow into appliance.
Repressurize in 500psi steps while checking for leakage until working
pressure is reached. Verify appliance pressure by means of the gauges.
Note that the back pressure valve will limit gas flow from leaving

INSTALLATION
OPERATION
MAINTENANCE & REPAIR
The possible applications of the priority valve (a.k.a. back
pressure valve or pressure maintaining valve) are numerous
but typically serving to increase the efficiency of the
purification process. The valve maintains a constant high
pressure load on both the coalescor and adsorbent bed thus
increasing filter life as much as 400%..
This is a sturdy valve, designed to withstand harsh
environments and brutal usage. All internal wetted areas
are constructed of corrosion resistant materials including
stainless steel and hard-coat aluminum. An internal check
valve provides for non-return of the compressed gas. Three
(3) discharge ports conveniently turn this valve into a very
practical manifold block as well.
Two (2) mounting points are provided in cases where it is
desirable to affix or flush mount the valve. Use a suitable pipe
thread sealant such as TEFLON tape on all connections to the
inlet/outlet ports. It is suggested that a gauge be installed at
the outlet port on the face of the valve. This will accommodate
setting of the open point of the valve as well as downstream
pressure at any time. Any unused outlet ports may be
plugged. If the valve is installed in a piping line ensure that it is
adequately supported. WARNING: This product is NOT
approved for use in compressed oxygen environments.
The valve comes pre-tested and set at approximately
2000psi. This can be adjusted to your needs by loosening
the locking nut and then rotating the adjusting screw
clockwise to increase or counter-clockwise to decrease the
opening pressure.
In operation, the Priority Valve will maintain it's set pressure
upstream and regulate enough gas flow through the valve in
order to sustain this pressure.
Routine maintenance is generally not required. Under
extended or severe operation it is helpful to re-lubricate the
piston or replace the poppet. Refer to the blow up illustration
for order of assembly / disassembly. Reset the valve as
instructed above. In any case, the valve may be returned to
the factory for repair.
