Introduction

Ultravation manufactures several configurations of ultraviolet (UV) disinfection products
to meet any installation criteria. UltraMAX™ two-lamp UV systems are designed to treat
up to a 5 ton HVAC system or cover 3,500 sq ft.

Ultravation® UltraMAX™ products have been designed for peak performance in the cool
temperatures of the supply plenum of an HVAC system.

We suggest mounting the UV lamps and optional Re-Fresh™ Odor reduction module on
the exit or supply side of the HVAC system and before the ductwork branches off.
Installing UV equipment in the HVAC system return may degrade the media filter and/or
collect dirt particles on the UV lamp glass gradually decreasing performance. If there is
obvious microbial growth in the return duct, then installing the UV system (or a second
system) in the return can be the best solution.

However, caution must be taken to ensure that no light from the UV lamp(s)
can come in contact with any installed media filters or can be seen from
outside the HVAC system when it is running. Remember: DO NOT look at UV
light without proper eye protection.

Ultravation’s exclusive Re-Fresh™ Odor Reduction Module (optional) performs
continuous photocatalytic air processing, constantly reducing or eliminating hundreds of
common VOC odors while enhancing the germicidal effect of the system resulting in
clean, fresh, breathable air.

UltraMAX UV systems produce no ozone. No harmful by-products or off-gassing takes
place in the sterilization process or the photocatalytic process.

SAFETY PRECAUTIONS:

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
replacing lamps 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.

Important information about UV lamp replacements:

Replace UV lamps each year in order to maintain optimum effectiveness in the reduc­tion of pathogens such as bacteria, viruses and microscopic mold. Lamps operating
after a period of two years do not provide adequate reduction of pathogens and
must be replaced. Lamps operating beyond 18,000 hours (two years) draw excessive
electrical current which may result in damage to the UV system. If UV lamp(s) have
been operating for more than two years, the system must be turned off until replace­ment lamp(s) are installed. Failure to do so may void the warranty.

Installation

Installation steps for remote lamp mounting, remote lamp replacement, and
external mounting of power supply:

1. Remove the cover from the electronic housing.

2. 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 unit in place with two self-tapping screws (supplied).

3. Re-fasten housing cover to the power supply.

UV Lamp Installation:

1. Select location for UV lamp module, drill a 1" hole for each lamp. Fasten mounting
plate over drilled hole with screws provided.

2. Insert UV lamp module into 1" opening. Attach to mounting plate with the two
provided self-tapping screws.

3. Plug the lamp connector onto the installed UV lamp assembly. Be sure the four pin­holes are orientated properly to the four mating pins of the lamp (see
diagram, below).

4. Connect full time power to unit. (The UV system should be powered constantly, not
cycled with HVAC system power).

IMPORTANT: T3 Lamp Connection

Lamp pins are in a rectangular pattern (NOT
square). The plug can be connected to the
lamp in either of the two ways that match
the pin pattern. The T3 UV lamp assembly
can be removed independently, simply by
removing the two screws in the lamp base.

ELECTRICAL POWER CONNECTION 24VAC UNITS

All 24 volt UV equipment for HVAC systems (regardless of manufacturer) must be
installed using a separate, dedicated minimum 40VA transformer to avoid the possibilty
of voiding UL certification of the HVAC system.

This product is equipped with a 1.75 amp in-line fuse for both surge and electrical arc
protection. Replace only with AGC 1.75 AMP (2 AMP max) fuse (available from
Ultravation or authorized distributor, part number EL-PP-0001). Failure to do so will
defeat the design and void the warranty.

Installation options for Internal Bracket/Light Shield (ILS)

The Internal Bracket/Light Shield (optional some models) is a versatile kit that can be
used for mounting the UVC lamp(s) completely inside the HVAC system via a screw
mount or using the heavy duty magnet for even easier mounting. It can also serve as a
light shield to block the intense UVC energy from breaking down non metallic
materials such as filters, or to prevent UVC energy from escaping through air return
grills. For the full range of configurations see accompanying installation option sheet
DC-IH-3334.

Installation steps for optional exclusive Refresh™ PCO Odor Reduction Module:

1. Find a location adjacent to the UV lamps to mount the PCO module. Activation of
the PCO module requires UV light shining on its surface. It can be mounted within
inches of the UV lamp or if necessary it can be within 2 ft. of direct UV light source
and still function.

2. Drill one 2 1/2" diameter hole at the desired location. Fasten the base plate of the
module to the duct or air handler with the four supplied screws.

3. The PCO module measures 14 3/4" inches long by 2 1/2" diameter. The surface
area of the module relates directly to the amount of VOCs it can break down. If
necessary the module can be trimmed to a shorter length to accommodate installa­tion. For additional effectiveness, install additional PCO modules in the area of the
UV lights, thereby increasing the airborne bacteria disinfection rate and the removal
of VOC odors. PCO modules may be installed completely inside the HVAC system.

Installation steps for UV Viewport

1. Find a location on the air handler or ductwork that will be in direct line of sight to
the UV lamps where a 3/8" inch hole can be safely drilled.

2. Affix the UV Viewport label to air handler or ductwork.

3. Drill the hole through air handler or ductwork using the label as a template.

4. Insert and press in the UV Viewport until it snaps into place.

5. The Viewport glows blue when the lamp(s) are operational (but does not allow actual
UVC light to pass through it).

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. This slowly reduces the amount
of UV light generated to disinfect the air and surfaces. For optimum air stream disin­fection UV lamps should be replaced on an annual basis. For surface disinfection,
lamp replacement should be performed no later than every two years.

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.

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. The model and serial number are
located on an end panel of the base unit.

Please note: It is a normal characteristic of all UV lamps to blacken around the
filaments of the lamp. This does not signify the lamp is defective or not emitting
ultraviolet light. A UV lamp is defective only if it will not light. UV lamps that operate
do not qualify for warranty coverage.

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

• The electronic circuit of a 2-lamp system only operates when both lamps are on.

• Verify the unit has power (24VAC or 120V - 240V depending on installation).

• Be sure the power switch is in the ON position.

• Verify if in fact the UV lamps are ON or OFF.

• Check that lamps are securely plugged into their sockets.

• Press the unit reset. If the unit and the unit does not reset, wait 5 minutes before
trying again.

continued …

Troubleshooting, continued

• Verify that the in-line surge protection fuse is still functional. If needed, replace only
with an AGC 1.75 AMP (2 AMP max) fuse.

• Determine what signal, if any, the UV Lamp Monitor LED is emitting. (See the
UVLampMonitor chart below.)

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

Note: If just one UVC lamp of a 2-lamp system operates, make sure the lamp

connection is correct (see T3 connection illustration at left).

Note: A flashing red every 1 second and a beep every 1 second does not necessarily
mean the lamps are defective or no longer emitting UV, it is sensing that the lamp or
lamps in the unit are not on. This could be caused by other factors. In this case, a
service technician should be contacted.

Lamp Replacement and Reset Procedure

See “UV Lamp Installation” for replacement procedure.

Note: When replacing lamps disconnect power to the unit first.

After the lamps are in place, complete steps 1-4 below to reset the service indicator
light to 0. For optimum air stream disinfection it is recommended that the UV-C
lamp(s) be replaced on an annual basis.

Setting the Service Indicator Light (FOR UMX SERIES ONLY):

We recommend that a certified technician perform this operation. (For integrated lamp
UMX models the cover must be removed and power left on – the reset switch is inside
the unit.)

1. To set or reset the annual service indicator the unit must have power connected.

2. Press down and hold the square yellow RESET button (hold down for 10 sec.). It is
located below LED Viewport on the end of the electrical housing. The LED turns
GREEN while the button is depressed.

3. Release the square yellow RESET button. The LED will now glow green
continuously indicating the reset procedure was successful.

There are NO user serviceable parts inside. Refer servicing to qualified service personnel.
