Surface Treatment System
When installed next to the cooling coil, the Surface Treatment
System prevents a high percentage of the growth of
micro-organisms such as mold that may grow on duct
surfaces, coils and drain pans. Individual results depend on
careful installation and maintenance. See. Fig. 2.
Fig. 2. Typical Surface Treatment installations.
IMPORTANT
If mounting options are limited, protect plastic or
rubber materials listed in CAUTION with ultraviolet-
resistant material such as aluminum foil duct tape.
NOTE: When the installer is uncertain about whether the drip
pan in the installation can tolerate UV exposure,
consult the UV exposure white paper, form no.

1.
Choose a location that is readily accessible for regular
inspection and cleaning. Fig. 1 and 2 and show possible
mounting locations.
2.
Allow clearance in front of the device for removing the
lamp assemblies. Fig. 3 shows lamp assembly lengths.
3.
Be sure depth can accommodate full length of UV lamp
for your model as shown in Fig. 3.
4.
Be sure duct mounting location is 8 in. wide minimum.
5.
Be sure 120 Vac electrical outlet is within range of unit to
plug in the power cord.
6.
Select single-lamp and dual-lamp air treatment system
location on HVAC return air duct that is easily accessible
with a flat mounting surface. Select surface treatment
system location on HVAC supply air duct that is easily
accessible with a flat mounting surface; locate the unit so
the lamp can surround the evaporator coil and drip pan
with ultraviolet light.
7.
Mount to allow correct operation:
a. Do not mount upside down.
b. Do not mount with lamps facing up.
CAUTION
Sharp Edges Hazard.
Can cause personal injury.
Be careful when inserting ultraviolet device into sheet
metal cutout.
Wear protective gloves when working near sheet metal.
Duct Mounting
Use the following instructions to mount the UV System on the
air duct of an HVAC system:
1.
Disconnect power to the HVAC system before installing
the UV System.
2.
Select the appropriate template for your model (see Fig.
18-20).
3.
Place the appropriate template for your model on the
duct surface, centering the bulb hole(s) on the duct.
4.
Mark the location on the duct for 2 in. diameter bulb
hole(s), unit mounting-screw pilot holes, and when
installing a return air model, the 1-1/2 in. airflow sensor
hole.
5.
Cut 2 in. bulb hole(s) and 1-1/2 in. airflow sensor hole in
the duct. Remove any burrs.
Note that the airflow sensor
protrudes out of backside of device. Be careful to avoid
scratching or damaging the airflow sensor.
6.
Use a 3/32 in. drill for pilot holes for mounting screws.
7.
Be sure duct surface is flat after all holes are drilled.
8.
Position entire base unit on duct.
Be sure bulb and
airflow sensor holes in duct align with unit holes. Be
careful to avoid scratching or damaging the airflow
sensor.
9.
Install unit into duct using three (or two, depending on
model) no.10, 2 in. Phillips head sheet metal mounting
screws provided. (A spare screw is provided for three-
screw model.)
10.
Tighten screws to 12 to 14 in.-lb so space between case
and duct is sealed.
