Installation
• Carefully remove the lamps from the packaging and
install them one at a time. There are black lamp clips
already installed in the sheet metal rack that will be used
to hold the UV lamps.
• The 61” lamp will be mounted to the clips that are furthest
to the left of the unit and the clips in the center of the unit.
The 33” lamps are staggered above the 61” lamp.
• The receiving power connection to the lamp must be
facing the outer edge of the unit so that power can easily
be connected/disconnected to the lamp. This connection
has 4 pins on it and is on the end of the bulb.
Place the UV lamp evenly between the two clips and press the
bulb into the center of the spring clip until the bulb is held rmly
in the center semicircle. When pressing the bulb into the clip,
apply pressure to the lamp directly above the clip to prevent
fracturing the lamp as detailed in Figure 123.
Figure 123: Spring Clip Handling
Once the bulb is installed into the clip, connect the wire
harness to the end of the bulb. The wire harness is shielded by
a exible metal conduit and will already be installed in the unit.
There will be one power harness per bulb.
Installing PCO Panels and Carbon Filters
• Photocatalytic oxidation panels (PCO) are located
upstream and/or downstream of the UV lights depending
on the option congured in the unit.
• PCO panels and carbon lters will slide into a traditional
lter rack downstream of the UV lights, where there will
be a 2”-wide lter rack as seen in Figure 124.
• PCO panels should be mounted upstream of the carbon
lters. Carbon lters should be replaced at the same
interval as the coil pre lters.
• PCO panels will require cleaning once a year or more if
there is excess buildup of particulate on the panels. Wash
with low pressure water and leave to air dry. Once all
panels are dry, they can be reinstalled in the unit.

Replacing UV Light Bulbs
Ultraviolet bulbs should be replaced after 9,000 hours of use or
annually, even if the bulbs still emit light. The blue light emitted
from the bulb is not an indication of UV intensity. The UV light
intensity emitted from the bulbs degrades over time and will
no longer provide the same disinfection benet. Replacement
bulbs must be the exact same size and from the same
manufacturer.
1. Disconnect power to unit and UV lamps.
2. Disconnect power harness at the base of the sheet metal
rack holding the UV lamps.
3. Disconnect metal conduit power harness connected to
the UV lamp.
