The UltraMAX™ EZUV

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. Mount mounting plate over

drilled hole with screws provided. Insert UV lamp module into hole. Attach to HVAC

system with two self-tapping screws (supplied).

3. Plug 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

other side of this manual).

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 manual).

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 to accommodate installation of the viewport.

Important information about UV lamp replacements

(See Lamp Replacement Safety Reset)

Replace UV lamps each year in order to maintain optimum effectiveness in the reduc-
tion 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 elec-
trical 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 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.


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 replace-
ment should be performed no later than every two years (see above, “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.

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:

• Verify if in fact the UV lamps are on or off (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.

• If you have an inline fuse verify that the surge protection fuse is still functional. If

necessary, replace with a 1 to 2 AMP maximum AGC type fuse.

• Be sure lamps are securely plugged into their sockets, no loose wires, and in the

correct orientation (see other side of this manual).

• 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.

UL Listed. The health aspects associated with the use of this product and its ability to aid in disinfection of environmental
air have not been investigated by UL.



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.

Disconnecting power is required for lamp replacement. NEW lamps will not light if
power has not been disconnected. Power must be off for at least FIVE seconds.
