(CSA's) visit www.gaylordventilation.com and go to "Service Agencies".
WARNING: Certified Service Agent maintenance and repair warning. Do not defeat any Safety Interlocks
during cleaning, maintenance and repair.
Safety Requirements
Caution: Exposure to UV light is harmful to skin and eyes. Before servicing or repairing any of the UV Sys-
tem read and perform the following safety requirements.
Overview
The ELXC-UVi Ventilator is equipped with light attenuation barriers and Safety Interlocks to protect operators
from direct exposure to UV light. All safety precautions called for in this manual must be followed to avoid
the potential for harm to service personnel or operators.
As with many types of technology if it is not used properly and/or proper precautions are not taken there
is the potential for injury or harm. This is especially true of UV light due to the fact that it does not physi-
cally hurt at the time of exposure. UV generated in these Ventilators is greater than what results from direct
exposure to the sun. Under no circumstances is it acceptable to view the lighted lamps without proper eye
protection or expose bare skin directly to the light. All safety precautions called for in this manual must be
followed to avoid the potential for harm to service personnel and/or operators.
Personal Protective Equipment
1. Eye protection that prevents 100% of UV light from being transmitted through the lens must be worn at
all times when replacing the UV Lamps on any ELXC-UVi Ventilator that is energized and/or has the po-
tential to be energized and expose personnel to UV light.
2. Whenever service work is performed it is recommended that long sleeve shirts and pants be worn to
minimize the potential for inadvertent exposure of the skin to UV light.
Preventive Maintenance
The following Preventive Maintenance items must be performed by a trained and qualified Certified Service
Agency at a frequency shown on page 3-2, Table T-3-2-1, EXHAUST SYSTEM INSPECTION SCHEDULE. These
tasks involve potential exposure to high doses of UV light and live electrical components. There is a risk of
shock, injury and/or death from contact with live electrical components.
1. Testing UV Lamps and Ballasts
(For these tests all XGS Extractors must be in place, the Extractor Access Doors closed and all UV Module
Access Doors in place and latched.)
a. Turn on the exhaust fan at the Gaylord Command Center. The "UVi SYSTEM ON" green Status Light in
each Ventilator Section should be on. In addition to the Status Lights on the Ventilator, the Gaylord
Command Center should display text indicating the similar message as the Status Lights.
