SECTION 3 - MAINTENANCE (CONTINUED)
UVC EMITTER LAMPS
If purchased, the contractor is responsible for installing
the UV lamps, and connecting a 120 volt power supply as
shown in Figure 52 (below). Krueger’s factory provides the
following pre-wired parts.
•
Internal wiring with a magnetic door safety switch
•
A lockable disconnect switch with a Press to Test pilot
light
•
A latching circuit that has to be manually re-energized
on the AHU’s exterior after a door has been opened
and closed.
Three Types of Lamps
Three different types of UV lamps are used in AHUs:
V-Mod, V-Ray, and V-Max Grid.
V-Mod Lamps - Install the two-pronged lamps into the
slotted fixtures as shown in Figure 53 (right), then rotate
the lamp 90°.
V-Ray and V-Max Grid Lamps - Fit the four-pronged lamp
into the clamp mounted on the UV segment where a pigtail
is installed. Insert the prongs into the pigtail plug.
CAUTION -
Use clean cotton rags, clean jersey or
latex gloves to handle the lamps. DO NOT touch UV
lamps with bare hands or leather gloves because
the oil will damage the lamps.
