Before You Begin:

Read and understand this entire guide, the luminaire installation
instructions, and any site-specific documents before attempting to install,
commission or operate these luminaires. Failure to read and follow all
provided instructions may result in damage or injury.

It is the responsibility of the installer to
ensure that persons will not be exposed to
excessive UV radiation during equipment
operation. This will require the installer to
conduct an assessment of irradiance levels
per the instructions listed in this document
in the surrounding occupied spaces prior
to occupancy and to repeat assessment
whenever relamping is completed.

This document applies to following products:

Fail-Safe GAC - Germicidal UV 2x2 Grid Ceiling Mount
