lamp filaments. It also monitors elapsed
time and reminds after 18,000 hours of
operation that lamps need to be replaced.
Below is a chart that describes how to

AFETY PRECAUTIONS:

S

It is recommended that this unit be installed and maintained by a trained technician:

WARNING: UV Hazard. Always protect eyes from ultraviolet light.
NEVER look at UV lamps in operation. Unplug or disconnect power before
re-lamping or servicing.

WARNING: Severe eye damage or temporary blinding may occur.

WARNING: DO NOT operate outside of air handler. Mount lamp base to
duct first.

WARNING: No openings in HVAC system are allowed which would give
direct line-of-sight to the UV light.

In the event of accidental breakage or replacement of the ultraviolet lamp, please
ensure that the lamp is disposed of in accordance with local and state environmental
laws regarding fluorescent lamps containing mercury.

Notice: All wiring inside air handling system in direct line of site of the UV lamp must
be shielded with aluminum foil tape or equivalent non-combustible material. When
installing this unit, select a mounting location that prevents ultraviolet light exposure
to plastic non UV-rated flexible duct liner or other plastic components with unknown
resistance to ultraviolet light. Ultraviolet light may cause color shift or structural
degradation of plastic HVAC components. If installing where UV light can directly
contact fiberglass duct board, contact manufacturer of fiberglass product for advice
on UV rating. If unknown, install metal sheathing or foil tape to completely protect
fiberglass duct board from UV light exposure.

Troubleshooting

Ultravation® air disinfection equipment is designed to provide many years of trouble
free operation. In the unlikely event of a problem, please contact your local HVAC
professional or Ultravation directly. Before calling for service, you should have the
model number, serial number, and purchase date.

If you are troubleshooting the unit, please check the following:

• To save energy and maintain performance, the EZUV Signature Series automatically
turns off if the lamp has not been changed after two years. If this is the case,
replace the lamp and press the reset button on the side of the power supply.

• Verify that the UV lamp(s) is on or off—but never look at a UV lamp in operation!
You can safely confirm operation by way of the UV viewport installed with the unit.

• Verify the unit has power. Check voltage requirement on power supply label and
confirm proper power is supplied.

• Be sure lamps are securely plugged into their sockets, no loose wires, and in the
correct orientation (see other side of this sheet).

• If possible install a new lamp to determine whether the problem is the lamp or the
power supply.

Remember: DO NOT look at UV light without proper eye protection.

Installation and Maintenance

We recommend that this unit be installed and maintained by a trained HVAC
professional technician.

Installation steps for external mounting of power supply:

1. Determine a suitable location to install unit housing. Mounting location should be of
sufficient strength as to support the unit, otherwise reinforcement of the ductwork may
be necessary. Fasten the unit in place with two self-tapping screws (supplied).

2. Select location for UV lamp module. Drill a 1" hole. Install mounting plate over
drilled hole with screws provided. Insert UV lamp into hole. Attach to mounting plate
system with two self-tapping screws (supplied).

3. Attached the rubber lamp connector fully onto the installed UV lamp assembly. Be
sure the four pinholes are orientated properly to the four matching pins on the lamp
(see diagram at right).

4. Connect power wires to a dedicated minimum 40VA transformer or hardwire to
appropriate voltage based on requirements listed on power supply label.

This should be done in accordance with all state and local electrical and
building codes.

Notes: The UV lamp assembly can be removed independently, by removing the

two screws in the lamp holder.

The rectangular pin pattern allows connection in two positions (see other
side of this sheet).

A UV status viewport lens is supplied to verify lamp operation. Drill a 3/8"
hole within a 3" radius around the lamp, and on the “lamp side” of the “V” in
the light shield. Snap viewport into place.

Important! Read before installation

The screw holes on the UV lamp
need to be parallel to the lamp lead
cord on the back of the female
receptacle for correct assembly!

Note that lamp connector pin pattern
is NOT square.

It can be mounted from either side
and top or bottom depending on the
orientation of the installed lamp.

Installation steps for internal mounting of power supply:

1. Mount power supply inside of the air handler but out of the air stream as much as
possible. Place the power supply close to the control panel for ease of connecting to
24 VAC or appropriate voltage according to the power supply label.

2. To utilize the internal mounting bracket, first install the bracket inside the air handler
in a location that will position the UV lamp such that it bathes the entire surface to be
treated. Plug the lamp connector onto the lamp and snap into the bracket.

Note: The rectangular pin pattern can be mated in two positions only.

3. Connect power wires to a dedicated minimum 40VA transformer. This must be done in
accordance with all state and local electrical and building codes.

Maintenance

Never perform maintenance on the UV unit without disconnecting power. Typical

maintenance consists of replacement of the ultraviolet (UV) lamps. UV lamps undergo a
photochemical process during operation, that slowly reduces the amount of UV light
generated to disinfect the air and surfaces. For optimum air stream disinfection UV lamps
should be replaced annually. For surface disinfection, lamp replacement should be
performed no later than every two years (see below, “Important Information about UV
lamp replacements”). When installing new lamps, ensure that the lamp glass is free from
any fingerprints or debris, as this may alter the path of the UV energy. Use rubbing
alcohol and a dry cloth to remove any surface contamination.

Important information about UV lamp replacements

Replace UV lamp(s) annually in order to maintain optimum effectiveness in the reduction
of pathogens such as bacteria, viruses and microscopic mold. Lamps operating after a
period of 18,000 hours (two years) no longer provide adequate UV-C. When the UV lamp(s)
reach the end of the 18,000 hour useful operating life, the unit automatically turns off. The
UV lamp must be replaced and the power supply reset. Do not reset the power supply

without replacing the UV lamp as worn out UV lamps draw excessive electrical
current which may result in damage to the UV system, and may void the warranty.

a separate, dedicated minimum 40VA transformer to
avoid the possibility of voiding UL certification of the
HVAC system.
