SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should in-
stall, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions such as changing bulbs. All other operations should be
performed by trained service personnel. When working on air-
conditioning equipment, observe precautions in the literature,
tags and labels attached to the unit or accessory, and other safe-
ty precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves.
GENERAL
Carrier’s commercial rooftop ultra-violet germicidal lamps
are designed to kill odor causing mold and fungus that may de-
velop in the wet evaporator section of an HVAC unit. The high
output, low temperature germicidal lamps are installed in the
evaporator section of the HVAC unit, and are pointed directly
at the evaporator coil and condensate pan. The short wave
length ultra-violet band light inhibits and kills mold, fungus,
and microbial growth.
The Carrier germicidal lamps have been specifically de-
signed and optimized for 40 to 45 F, high-humidity operation in
a moving airstream inside an HVAC unit. The Carrier germi-
cidal lamps have output ratings at 45 F in a 400 fpm airflow of
120 microwatts/cm2at a 1 meter range.
PACKAGE USAGE
Before installing accessory or performing maintenance or
service on accessory, turn off main power switch to unit.
Electrical shock can cause injury or death. There may be
more than one disconnect switch.
Never expose eyes or skin to ultra-violet light from any
source. After installation, provide an interlock to turn off
germicidal lamps when access door is opened. Lamp must
be off before entering HVAC unit to perform maintenance
or service. Personal injury may result.
Use only specified high-output, low temperature bulbs with
this accessory. Use of a lower wattage or incorrect bulb can
result in damage to accessory or bulb. Correct bulbs have a
blue end cap.
Do not touch emitter glass without gloves. Damage to bulb
may result. Oil from fingerprints will permanently etch
glass of bulb and weaken structure. Clean bulb after
handling.
Bulb contains a small quantity of mercury. If a bulb breaks,
clean and dispose with care.

INSTALLATION
Location — Germicidal lamps are installed in the evaporator
section where they will have contact with the air stream and
moist surfaces. Refer to the installation locations provided in
Fig. 1-4. The stainless steel power supply section of the acces-
sory is installed on the outside of the unit and is waterproof.
See Fig. 5 for accessory dimensions.
Make sure site can be supplied with the necessary power re-
quirements. Ensure that there is adequate clearance for service.
Installation (48/50HJ,TJ015-028 Units and
50HJQ014, 016 Units) — Perform the following proce-
dure to install the germicidal lamp:
1. Turn off all power to unit.
2. Install reflective material (field-supplied) in installa-
tion location if desired. Reflecting ultra-violet light
energy is recommended to enhance performance and
reduce shadows. Lining the installation area with alu-
minum or aluminum foil allows light energy to reflect
instead of being absorbed, increasing the effectiveness
of the germicidal lamp.
3. Ultra violet light may damage certain plastics and
exposed non-UVC (Ultra Violet Radiation, C-Band)
protected wires. (Drain pans will not be damaged.)
Wrap exposed plastic and wiring with aluminum tape
or use metal conduit.
4. Mount field-provided light-switch disconnect switch
on unit hood. See Fig. 1, 6, and 7. Disconnect switch
should have a waterproof housing.
5. A separate source power supply must be routed to the
accessory germicidal lamp’s unit mounted disconnect
switch per applicable codes. Unit wiring and control
box connections should not be used. Refer to the Pack-
age Usage table for electrical characteristics of power
supply. Power source must be a suitable fused,
grounded, protected source with the correct voltage.
Other voltages will permanently damage the germi-
cidal lamp.
Wire per Table 1.
Table 1 — Wiring Recommendations
6. Any hinged potential access panel or door to the instal-
lation area must be interlocked with the accessory
power source to turn the lamp off if the door is opened.
Access doors should be labelled with appropriate
warnings about exposure to ultra-violet light.
A pushbutton door interlock switch (Carrier Part No.
HR54ZA101) is required on all hinged access panels.
Use a field-fabricated and -installed bracket to mount
the door interlock switch to the unit corner post. See
Fig. 6 and 8. Use insulated sleeve terminals for con-
nection to interlock switch. The pushbutton door inter-
lock switch is not required on non-hinged access
panels. Door interlock switch should be located on the
side of the access door that opens. Locate the switch
near the top of the door so it will not be in a location
where it interferes with maintenance or service.
Run wiring into disconnect switch. Door interlock
switch should be wired into the power (Black) lead,
between the disconnect switch and the germicidal
lamp, to break power to the accessory when the door is
opened.
7. Access doors may be equipped with a glass or Lexan®
window to view lamps.
A glass or Lexan window will not pass ultra-violet
rays and is not a safety risk.
8. Using the accessory as a template, mark two 1-in.
insertion holes on the mounting surface. Mark 8 holes
for accessory mounting. See Fig. 1 and 5 for location.
The 1-in. holes are used for electrical connections and
the germicidal bulb. See Fig. 5.

Bulbs need periodic replacement to maintain design specifi-
cations. Replace bulbs after 6000 hours of operation or 1 year,
whichever comes first. For best performance, replace bulbs at
the beginning of each cooling season.
Bulb output can also be checked with a UVC radiometer.
Replace bulb when output falls to 70% of initial reading
The following bulbs can safely be used with this accessory:
• CRSGLTUB001A00 (16-in. tube)
• CRSGLTUB002A00 (20-in. tube)
• CRSGLTUB003A00 (24-in. tube)
• CRSGLTUB004A00 (30-in. tube)
• CRSGLTUB005A00 (36-in. tube)
Other bulbs may plug into the accessory, but they should not
be used. Non-approved bulbs will overheat bulb and power
source. Normal operation temperature for the bulb is 80 F. Nor-
mal operation temperature for the power source is 125 F.
OPERATION
While lit, bulb color should be light blue. If bulb color
changes to red or flickers, replace the bulb. Bulbs that are not
light blue will not emit ultra-violet radiation and will not kill
harmful bacteria or fungi.
Fiberglass filter media are recommended for operation of
HVAC when filters are exposed to ultra-violet lamps. Polyester
or cotton filters are subject to ultra-violet degradation and are
not recommended.
Use only specified high-output, low temperature bulbs with
this accessory. Use of a lower wattage or incorrect bulb can
result in damage to accessory or bulb. Correct bulbs have a
blue end cap.
