The cabinet may either be installed on a level installation
deck or platform adjacent to the air handler or it may be
suspended from the rafters using metal strapping. If straps
are used, take care when attaching straps to the cabinet.
Ensure fasteners do not interfere with internal components
of the cabinet. The air filter and UVA Lampholder / PCO
cartridge must be able to slide freely into the cabinet.
1. Locate and remove the UVA Lampholder / PCO cartridge
from the cabinet.
NOTE:
Oil on metal surfaces may cause odors. Use mild
soap and water solution to wash all new duct and
transition surfaces.
2.
Use the air flow directional label on the inside of the UVA
Lampholder / PCO cartridge to orient the unit.
3. Properly position the cabinet next to the return air
opening of the air handling unit. Use sheet metal screws
1” (25mm) maximum length, rivets or other appropriate
fasteners to secure cabinet to the return air side of the
air handling unit.
4. Use field-provided sheet metal screws 1” (25mm)
maximum length to fasten the return air duct to the other
side of the cabinet. Attachment holes are provided in
housing.
5. Use field-provided aluminum foil tape or water-based
mastic to seal all joints between the cabinet, air handler
and duct.
6. In high humidity applications, wrap cabinet with field-
provided 2” (50mm) foil-faced insulation (foil on the
outside) to prevent condensation.
