Precautions
The Lighthouse Isokinetic High Pressure Diffuser is designed to provide safe,
reliable operation. The following good practices will ensure the safety of
both personnel and instrumentation:
1. Ensure that the high pressure source is turned off before installing or
disconnecting the High Pressure Diffuser.
2. Be sure that the High Pressure Diffuser is installed so that air flows
with the arrow. The end of the Diffuser marked SAMPLE IN (PRESSURE) must be
connected to the high pressure source.
3. Ensure that all fittings, connectors, and adapters are tight (finger tight
plus a 45° turn) before applying high pressure air to the inlet of the
Diffuser.

Operational Safety
Lighthouse Worldwide Solutions
WARNING: Do not block or plug the exhaust holes in the Vented version, nor plug the exhaust port on the Ported version of the High Pressure Diffuser. This action will pressurize the attached particle counting instrument and can result in extreme damage.
WARNING: Do not attempt to disassemble the High Pressure Diffuser while in
operation. Remove the high pressure input from the inlet of the Diffuser
before proceeding with adjustments.
Servicing Safety
WARNING: Do not attempt to disassemble the High Pressure Diffuser while in
operation. Remove the high pressure input from the inlet of the Diffuser
before proceeding with any cleaning or parts replacement.
WARNING: This cleaning process detailed in this document involves the use of
solvent and flux remover. Improper use of these materials can be hazardous to
the user’s health. Carefully read the Material Safety Data Sheet for
precautions and guidelines for proper use.

2 Introduction
Overview
High Pressure Diffuser Operating Manual
The High Pressure Diffuser was designed for use with Lighthouse Airborne
Particle Counters in applications where the sample is under pressure. Standard
applications include sampling of CDA, CO2, Nitrogen lines, and other inert
gases.
The Diffuser unit is available in a Vented or Ported version. The Vented
version allows overpressure to vent into the test area, while the Ported
version provides for connecting an exhaust line to route the overpressure to a
desired location.
The Vented Diffuser comes in either a 0.1 CFM or 1.0 CFM model, while the
Ported version has a 0.1 CFM, 1.0 CFM, 2.0 CFM, and 3.5 CFM model. Modifying
the length of the Adjustment tube based on the input pressure allows the
Diffuser unit to provide the proper flow output, providing accurate
measurement capability regardless of the pressure of the sampled medium. See
Chapter 3 in this manual for detailed instruction for adjusting the HPD for
different input pressures.
The High Pressure Diffuser is compatible with the entire line of Lighthouse
Solair, Remote, ApexP and ApexZ particle counters. When coupled with the
proper accessory kit, the 0.1 CFM HPD works with the Handheld line of
instruments as well.
· 402965281-1 (Accy: Handheld to HPD Plumbing) is needed when using the HPD
with LWS Handheld particle counters.

To maintain the warranty, keep the undamaged shipping container and all
packing material for reshipment of the instrument for
calibration/cleaning/repair. Order replacement containers and packing
materials only from Lighthouse, either
directly or through and authorized distributor.
Should it become necessary to return the unit to the factory for any reason,
contact Lighthouse Customer Service or visit the website,
www.golighthouse.com/rma, and obtain a Return Material Authorized (RMA)
number. Reference this number on all shipping documentation and purchase
orders. After receipt of the RMA number, follow the shipping instructions
below:
1. Use the original container, caps, and packing materials whenever possible.
Remove any attachments from the instrument.
2. If the original container and shipping materials are not available, wrap
the unit in “bubble pack”, surround it with shock absorbent material, and
place it in a double-wall carton. The instrument should be packed so that it
does not rattle around when the container is vigorously shaken. Contact
Lighthouse if a replacement shipping container is needed.
Warning: If the instrument is damaged during return shipping due to inadequate user packing, the warranty may be voided and additional repair charges may be due by the customer.
3. Seal the container or carton securely. Mark the container as “FRAGILE” and
write the RMA number on any unmarked corner.
4. Return the instrument to the address provided by your Lighthouse
representative or the RMA website.

Installation
High Pressure Diffuser Operating Manual
The installation of the High Pressure Diffuser has two major steps: Adjusting
the air flow at the output of the Diffuser, and plumbing the device into the
facility.
Adjusting the Output for Isokinetic Sampling Manipulation of the Adjustment
Tube allows the user to obtain the proper air flow out of the Diffuser by
correctly reducing the input High Pressure source. Figures 3-2 and 3-3 on the
following pages detail the required length of the Adjustment Tube for proper
flow rate out of the Diffuser based on the input pressure. Adjustment lengths
are identical for all models. Figure 3-2 shows English measurements, while
Figure 3-3 shows Metric measurements.
Adjustment Process: 1. Find your inlet pressure on the X-axis of the
appropriate graph.
2. Trace a vertical line from the inlet pressure to the graphed Isokinetic
Sampling curve.
3. At the intersection, trace a horizontal line to the left for the proper
length for the adjustment tube from the Y-axis labels.
4. Loosen the Locking Cap so the Adjustment Tube length can be changed.
Adjust this space

Outlet Fitting
Figure 3-1 Adjustment Tube 5. Carefully adjust the length of the tube to match
the measurement found in Step 3. 6. Tighten the Locking Cap, being careful not
to change the length of the Adjustment
Tube. Tighten the Cap finger tight, then use a wrench to tighten another 45°.
7. Check to ensure that the Adjustment Tube is the correct length.

Lighthouse Worldwide Solutions
Note: Always use new Gasket Fittings to ensure a good pressure seal.
Warning: Do not block or plug the exhaust holes in the Vented version, nor plug the exhaust port on the Ported version of the High Pressure Diffuser. This action will prevent the Diffuser from lowering the input pressure, pressurizing the connected particle counter and possibly causing extensive damage.

1. Attach a new Gasket Fitting to the ¼” VCR male connector on the input of
the Diffuser.
2. Connect the Diffuser Input to the high pressure supply using a ¼” VCR
female connector. Make the connection finger tight, then use a wrench to
tighten another 45°.
3. Connect the correct tubing size, dependent on the Diffuser version, to the
output. Insert the tubing into the compression fitting Make the connection
finger tight, then use a wrench to tighten another 45°.
4. For the Ported Diffuser: Connect the Exhaust Port to your exhaust system.
Loosen the nut on the Exhaust Port enough to insert the exhaust tubing through
the clamping ferrules, then tighten the nut finger tight plus another 45°
using a wrench.

4 Maintenance
High Pressure Diffuser Operating Manual
The Isokinetic High Pressure Diffuser may become contaminated with particles, especially if it is used or stored in an uncontrolled environment. If you suspect the Diffuser is contributing to particle counts, it can be disassembled and cleaned.
NOTE: Send the Diffuser in to a certified Service Center for disassembly and
cleaning. The threads and components have very tight tolerances and
can easily be unintentionally damaged.
Before performing any maintenance, refer to Chapter 1, Safety, and become familiar with the information contained therein. Be sure to remove the Diffuser from the High Pressure system before performing maintenance.
