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

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.

Introduction

Overview

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.

Unpacking, Inspecting, and Installing

The Isokinetic High-Pressure Diffuser has been thoroughly inspected and tested at the factory and is ready for use upon receipt, given no damage occurred in shipping.

Initial Inspection

Damage Inspection

Inspect the shipping carton for damage. If the container is damaged, notify the shipper immediately. If the carton is undamaged, open it carefully and inspect the contents for broken parts, scratches, dents, or other visible damage. If any is apparent, record the type and extent of the damage on the Incoming Inspection form and inform the shipping company. Photograph any damage noted for inclusion in reporting. Report any damages to Lighthouse Technical Support at 1-800-945-5905 (USA) or at 1-541-770-5905 (outside of USA) before proceeding.

Content Verification

Verify the contents of the package against the shipping list. If anything appears to be missing, contact your sales representative at Lighthouse immediately at 800-945-5905, or at techsupport@golighthouse.com.

Standard items included with each unit are:

1. Four Gasket Fittings
2. Read Me First
3. 10 ft. inlet hose

To maintain the warranty, keep the undamaged shipping container and all packing material for the 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

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
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.

Connecting the Diffuser

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.

Maintenance

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.
