Replacing UV Lamps
Overview
The UV Lamp Modules come in two lengths, a nominal 3'-0" and 5'-0". The length and number of
modules is dependent on the length of the Ventilator section (Refer to Table T-6-7-1). There are six UV
Lamps in each Module. Lamp #1 is at the front of the UV Module and Lamp #6 is at the back of the
Module (Refer to Figure 6-7-1). If the "UVi LAMP FAILURE" yellow status light on the Ventilator is on it
indicates that one or more Lamps has failed and it must be replaced.
