UV Module Ventilation Fans
Overview
There are three UV Module Ventilation Fans mounted on each UV Module (Refer to Figure 6-32-1). The
purpose of the Ventilation Fans is to push air into the UV Ballast Raceway to help it cool. The fans push
air into the raceway and the air then discharged trough the openings at each end of the raceway.
Checking the UV Module Ventilation Fans
The Ventilation Fans run anytime the UV system is on. To check for proper operation proceed as follows:
Caution: Testing the UV Module Ventilation Fans requires the use or UV protective glasses as a
small amount of UV light may be visible.
1.
Push the
START FAN
button on the Command Center. Check to make sure the green light on the
group of UVi Status Lights mounted on the Ventilator section is on.
2.
Open the UV Module Access Door.
3.
Push and hold in the Door Safety Switch (Refer to Figure 6-33-1) and observe the Ventilation Fans
operating. If operating, the test is complete and the Access Door can be closed. If not operating,
conduct an electrical test at the connection points for voltage. If there is voltage, the Ventilation Fan
is defective and must be replaced.
