INSTALLATION MANUAL - IRW-xPC/xPS - EN
Introduction
Thank you for selecting the FLIR IR window. This manual applies to models
IRW-6PC (6”), IRW-12PC (12”), and IRW-24PC (24”) aluminum windows and
IRW-6PS (6”), IRW-12PS (12”), and IRW-24PS (24”) stainless steel windows.
Preparation
Check that the package contains the IR
window, fitting template, IR window label, and
fitting hardware. See Fig-1.
The required tools and personal protection
equipment (PPE) are listed below; you will
need these materials to perform a successful
installation. Install the window on a vertical, flat surface; cut the
installation holes using an angle grinder or a nibbler tool.
Required Tools
• Metal cutting tool such as nibbler or
angle grinder (see Fig-2)
• Drill and 8mm (5/16
”
) drill bit
• Center punch
• De-burring tool or another file tool
• Socket or wrench (7/16”)
• Metal treatment product with anti-corrosion properties (paint, sealer)
Personal Protection Equipment (PPE)
Work gloves and safety glasses are required. Please comply with all site PPE
requirements.
Transmission Rate
Determine the transmission rate of the IR window you are installing. Notate
the transmission rate on the supplied IR window label.

Field of View
The Field of View table, below, shows the horizontal and vertical views (in
inches) for a variety of target distances for all models in this series. The
table is based on an IR camera with a standard 24o lens (2” lens diameter)
and 30o (max.) viewing angle (horizontal and vertical).
Field of View Reference Table (inches)
Fitting the template
Affix the supplied cutting template to the
appropriate area of the panel (Fig-3).
Hole punching
With the center punch, mark all fixing holes
labelled ‘A’ on the cutting template (Fig-4).
Drilling holes
Drill the center-punched holes using an 8mm (5/16”)
drill bit. If using a nibbler, drill a pilot hole along the
line labelled ‘B’.
Cut-out sizing
Refer to the table below to determine the size of the cut-out.

Cut-out Hole Sizing Reference Table
Making the cut-out
Make the cut-out using a nibbler, grinder, or similar
tool. Fig-5 shows an angle grinder fitted with a metal
cutting disc. After cutting a hole, smooth the rough
edges with a de-burring tool or file, and peel away
the remaining portion of the cutting template. To
protect against long-term corrosion, treat bare
metal surfaces with an anti-corrosion coating (paint,
sealer, etc.).
Installing the IR window
After cutting the hole, install the window:
• Place the unit, complete with seals, on the front of the panel
• Fit the hardware, ensuring that a nut is affixed on each stud
• With the 7/16” wrench, tighten the hardware to these specifications: 40
inch/lbs. or 4.52Nm
Attaching the label
Correctly label the IR window. We supply each IR window with a label; this
allows the camera operator to note the number of targets, target
emissivity, and transmission rates of the viewing pane for a variety of IR
cameras.
There may be multiple targets viewed through the IR viewing window; the
label can reflect these. The most common method of locating the required
targets is using the clock-face method, i.e. breakers at 4 o’clock position,
etc. Place all such data on the label. This label also uses a pre-printed bar
code system to allow for unique identification of each IR window.
