Safety Warnings

Safety

Isolate appliance from gas stream and depressurize prior to any service action. Never direct compressed gases at

bodily openings, eyes, or skin. Empty volatile gases from appliance into "drain gas” accumulator. Use appropriate

monitoring devices when dealing with critical or life support gas. Never exceed maximum operating conditions set

forth herein and/or on appliance nameplate. DO NOT use this appliance with Oxygen or Oxygen rich gas mixtures.

DO NOT connect this appliance to any system common with compressed oxygen. Disconnect all power supplies prior

to any service action. Some components used on this appliance may have a limited cycle lifespan and must be

replaced after that span has lapsed. Carefully read supplement section.

WARNING: When performing installation, adjustments, or any kind of service work: ensure that ALL pressure has first

been released and that ONLY trained personnel are carrying out tasks. NEVER remove retaining or adjusting screws

while device is under pressure. Safety valve should be returned to factory for service.

*Use only genuine Lawrence Factor replacement parts in order to guard the validity of your warranty and reliability of this appliance.

“HF SERIES” PURIFICATION APPLIANCE 3

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.

Instalation

Installation

It is assumed that the person installing this equipment is experienced in this field and fully acquainted with the

standard engineering practices.

Carefully unpack unit while ensuring to protect any sensitive devises such as pressure gauges and instruments.

DO NOT open any valves until unit is fully installed. This appliance has been carefully cleaned and protected against

contamination by atmospheric substances.

Refer to "IDENTIFICATION" page of this manual for location of components.

Appliance should be permanently affixed to a solid foundation by means of the anchoring holes located at the back of

the angle plate or (in the case of freestanding models) on the feet of the main chassis. Consider all piping joints when

orienting unit. DO NOT expose to excessive vibration.

Make up piping connections using joint compound which is compatible with the compressed gas application. If using

Teflon tape, do not allow to overlap edges of fittings since pieces may break loose under operation and cause

blockages.

Ÿ INLET CONNECTION should be made with a flexible hose.

Ÿ DISCHARGE CONNECTION should be made with a flexible hose. Note that the discharge is located at the

“back pressure valve" and there are two (2) ports for your use, one may be plugged if not required.

ŸRELIEF VALVE (if supplied) vents to atmosphere. An optional valve is available with NPT vent connection to

facilitate controlled discharge. Never tamper with relief valve settings.

ŸSYSTEM VENT discharges to atmosphere. An optional valve is available with NPT connection to facilitate

controlled discharge.

ŸA GROUNDING STRAP (not provided) must be attached to appliance.

ŸADEQUATE CLEARANCES must be allowed for servicing and cartridge changes.

ŸPROVIDE MEANS OF ISOLATION of this appliance from gas stream during service and cartridge changes.

ŸCONTAMINANT DETECTION (Optional) and alarm should be installed at discharge of appliance when in life

support air/gas service.

ŸOVER TEMPERATURE PROBE (Optional) and alarm with system shutdown devise should be installed at

discharge of compressor system as well as at the discharge of this appliance.

DO NOT install in location where ambient temperatures could exceed 110F degrees. DO NOT expose to electrical

charges or sparks. DO NOT install in system where gas flow rates could exceed the rating of this appliance. The

cartridge set must be installed prior to placing appliance into service. See section on “Installing Cartridges”.

Start Up / Operation

Start Up

The following procedure must be followed on initial start-up (AFTER CARTRIDGES HAVE BEEN INSTALLED) and

on each occasion where the appliance has been shutdown, serviced, or had a cartridge change.

NOTE that some appliances will come supplied with storage elements installed and slightly pressurized.

ŸVENT pressure from appliance using "System Vent". Be careful to drain the appliance slowly.

ŸREMOVE CARTRIDGE elements from holders according to "Cartridge Change" instructions and install new

cartridge elements. (This is done ONLY on initial start-up and on occasions where elements are due for change)

ŸCLOSE "System Vent Valve".

ŸPRESSURIZE appliance (SLOWLY) by opening the "Inlet Isolation Valve" (Optional). Bring up to full operating

pressure in 500 PSI steps while verifying there are no leaks in system.

ŸFLUSH contaminants from main appliance and piping by opening the "Outlet Isolation Valve" (Optional) and

permitting a small flow of air to discharge downstream or to atmosphere.

ŸTHE APPLIANCE MAY NOW BE PLACED ON LINE by fully opening the "Isolation Valves".

Operation

PRECAUTIONS: Always employ safe practices in handling of volatile or respiratory gases. Wear protective gear

when installing, operating, or servicing compressed gas apparatus. Never smoke, cause sparks or fire, or switch

electrical equipment while in the presence of volatile gases. MSDS are available for materials contained in disposable

cartridges. Use approved methods of disposal for cartridges. Never exceed ratings of this appliance.

INSTALLATION: Appliance must be properly installed prior to operation. See section titled "Installation".

CARTRIDGE INSTALLATION AND CHANGES: Cartridges must be properly installed prior to operation. See section

titled "Cartridge Installation".

SERVICE AND MAINTENANCE: See section titled "Maintenance Schedule" and instructions for each individual

component at the "Supplements" section of this manual.

Once the appliance is running it will manage itself. The operator need only perform proper maintenance, drain

condensate from mechanical filter when needed, and cartridge changes when due. The "Eyeball Indicator" will assist

the operator in determining cartridge change. See "Supplements" section of this manual.

DRAINING CONDENSATE FLUID must be done on a periodic basis. Since each system is operating under various

conditions the intervals between drainings should be established after operating experience.
