Model F120 UV/IR Flame Detector
Quarterly Lens Cleaning
!
WARNING: NEVER clean the sensor window with Windex or other commercial
glass cleaners. These often contain silicone or other UV inhibitors that will
prevent the sensor from detecting a re. Only use water or alcohol to wipe the
lens clean. The viewing window is not glass. The viewing window material is
sapphire.
Cleaning the outside surface of the viewing lens of any accumulated dust, dirt, lm or
debris will insure trouble free operation.
A clean, soft, lint-free cloth, tissue (lotion-free) or cotton swab should be used.
1. Wet the viewing window with water or alcohol.
2. Rub with a clean and dry cloth until the window is free of dirt, dust, or debris.
3. Let the viewing window dry completely.
4. Also check the small hole located just in front of the lens towards the top part.
Remove any dirt, dust or debris that may have accumulated in this part. The small
hole houses the Automatic Self-Check test source lamp.
Cleaning the lens once every 3 months will be sufcient in most cases. However, if the
detector is located in a dirty area, a shorter period between cleanings may be necessary to
eliminate faults due to a dirty lens.
Front and Rear Thread Lubrication
Should contamination to the existing lubricant occurs during installation or inspection, replace
with a high performance, high temperature, Molybdenum and Graphite grease. MOLYPLATE
®
and MOLYGRAPH
®
are two readily available greases that meet the requirements.
O-Ring Lubrication
The front housing O-ring may require additional lubrication when disassembling the detector
housing. A multipurpose synthetic lubricant with Teon, such as SUPER LUBE by Permatex
Industrial should be utilized. Petroleum jelly should not be used as lubricant. While it will
not attack the Viton O-ring, it does not provide the same lasting protection available with
synthetic Teon based lubricants.
Annual Verication
Factory recommends a system verication should be performed at least annually to verify
wiring, terminal connections and stability of mounting for all integral safety equipment including
but not limited to:
• Power supplies
• Field detection devices
• Control modules
• Audible and visual alarm devices
• Installed accessories
