PRODUCT APPLICATION
ConstruCtion
• The water purifier is designed to mount vertically.
• The water purifier’s chamber is passivated and electropolished type 304 Stainless Steel.
• The water purifier has a flow control valve inserted in the inlet fitting of the chamber.
• Translucent plug provides indication of germicidal lamp operation.
PrinCiPle of oPeration
The UltimateTM design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection chamber.
The dosage, as it applies to ultraviolet disinfection, is a function of time and the intensity of ultraviolet radiation to which the
water is exposed. The exposure time, in seconds, is the total time it takes the water to flow through the disinfection chamber
exposing it to the germicidal lamp. Exposure time is related to the flow rate; the higher the flow rate, the lower the exposure time
or the lower the flow rate, the higher the exposure time. The ultraviolet intensity is the amount of energy, per unit time, emitted by
the germicidal lamp. The dosage is the product of ultraviolet intensity and the exposure time. The operation of the UltimateTM is
as follows:
• Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
• Suspended microorganisms are exposed to the ultraviolet rays emitted by the germicidal lamp.
• The LED indicator light, located on the ballast, and the translucent plug on top of chamber provides visual indication of
germicidal lamp operation.
• Water leaving the purifier is instantly ready for use, no further contact time is required.
limitation of use
The water purifier is intended for the use with visually clear water, not colored, cloudy or turbid. See “Water Quality” section
below. The water purifier is NOT intended for the treatment of water that has an obvious contamination or intentional source,
such as raw sewage; nor is the unit intended to convert wastewater to microbiologically safe drinking water.
Water Quality
Water quality plays a major role in the transmission of germicidal ultraviolet rays. It is recommended that the water does not
exceed the following maximum concentration levels:
Table 1 - Maximum Concentration Levels
Turbidity < 1 NTU
Manganese 0.05 mg/1
Total Suspended Solids 10 mg /1
pH: 6.5 - 9.5
Color: None
Hardness 6 GPG or 102.6 PPM
Iron 0.3 mg/1
Tannins: < 0.1 ppm (0.1 mg/l)
UV Transmission >85% per cm*
* Contact Factory for recommendations on applications where UV transmission is < 85%
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added
measures to improve water quality to treatable levels. If, for any reason, it is believed the ultraviolet transmission is not
satisfactory, contact the factory.

INSTALLATION
loCation
1. The water purifier is intended for indoor use only. The water purifier is designed to mount vertically. The water purifier
should be protected from the elements and from temperatures below freezing. The ambient temperature, in the area
surrounding the water purifier, should be between 35oF and 100oF.
2. The water purifier must be connected to the cold water line only. Inlet water temperature should not exceed 100º F.
3. Electrical power supplied to the water purifier MUST match power requirements listed on the water purifier. Use of a voltage
surge protector is recommended.
4. Install water purifier within 48” of a known good ground. Water Purifier will need to be installed into approved
ground fault circuit interrupt (GFCI) receptacle. Where a 2-prong or unprotected 3-prong receptacle is encountered, it must
be replaced by a properly grounded Ground Fault Circuit Interrupt (GFCI) receptacle. Installation must be in accordance
with the National Electrical Code and any local codes and ordinances by a qualified electrician.
5. The water purifier should be located in a dry, well-lit area, which provides enough room to perform routine maintenance.
The UltimateTM is designed to mount in a vertical position, with the gland end up. Unit must be mounted to a secure wall or
structure using the brackets provided. It is not recommended to have the unit solely supported by the plumbing to the unit.
(The quartz sleeve and lamp are removed from the gland end.) Allow a service area of at least one chamber length from the
gland end, for replacement of the lamp or cleaning/replacing quartz sleeve, as well as a minimum of 6” on the opposite end of
the water purifier. Minimum clearance to the floor 18’’
6. Choose a location for your UltimateTM unit that is isolated from vibration. Vibration will damage lamp and lead to
premature system failure.
7. The water purifier should be located closest to the point of use. This eliminates the possibility of purified water being
re-contaminated by bacteria in the water distribution system after purification.
8. If your system is subject to water hammer conditions, it is recommended that you install a water hammer suppressor. Water
hammer may cause damage to the O-Ring seal.
9. As with any water handling device, the purifier should be located in an area where any possible condensation or
leakage from the purifier, accessories and/or plumbing will not result in damage to the purifier or to the area surrounding the
purifier. For added protection, it is recommended that a suitable drain pan be installed under the purifier. The drain
pan must be plumbed to an adequate, free flowing drain to prevent water damage in the event of a leak. There are
numerous leak detection/flood stop devices, available on the market today, designed to stop the flow of water, reducing
the chance of water damage due to leakage. For more details regarding leak prevention and/or limiting damages due
to leaks, please contact the factory. (Continued on Page 6)

All specifications, dimensional data, etc are approximate and subject to change without notice.
10. The water purifier should be located after all other water devices, such as De-ionizers, Water Softeners, Carbon Filters, Pre-
Filters, Reverse Osmosis, Pressure Tanks, and Pumps. This reduces the chance of the purified water being re-contaminated by
bacteria in any of these units.
11. Flow direction - water enters the unit through the lower fitting and exits through the upper fitting. The flow control is
mounted in the lower (inlet) fitting.
12. Installation requires a 5-micron sediment filter be installed, in line, prior to the water purifier. The sediment filter will stop or
trap any particulates from entering the water purifier. Particulates may cause deposit on the quartz sleeve as well as interfere
with the purifier’s ability to disinfect the water. The sediment filter may also help to reduce the amount of routine cleaning of
the quartz sleeve.
13. Shut off valves and unions should be installed on both the inlet and outlet sides of the water purifier. The use of bypass valves
is not recommended. The shut off valves allow the purifier to be isolated from the water supply, which is required when
removing the quartz sleeve.

installation
Always disconnect power to the unit, before performing any service or maintenance.
Lamp and quartz sleeve are easily damaged. Exercise care when removing or replacing.
NOTE: Screws are needed to secure water purifier to mounting surface and ARE NOT included. Please use screws
appropriate for the mounting surface.
• Unpack the water disinfection chamber and components following the steps in the “Unpacking” section on Page 5.
• Be sure that you have read and followed all the instructions mentioned in the “Location” section on Page 5.
• To allow for adequate room for installation and maintenance of the UltimateTM Ultraviolet Water Purifier refer to
“Dimensional Data” Figure 1 and Table 2 on Page 6.
• Use the “Dimensional Data” Figure 1 on Page 6, to mark the location of the bracket mounting pattern on the surface where
the unit will be mounted. (Refer to Dimensions “D”, “E”, & “F”.)
For added protection, a suitable drain pan must be installed under the purifier. The drain pan must be
plumbed to an adequate, free flowing drain to prevent water damage in the event of a leak. There are numerous leak
detection/flood stop devices, available on the market today, designed to stop the flow of water, reducing the chance of
water damage due to leakage. For more details regarding leak prevention and/or limiting damages due to leaks, please
contact the factory.
Installation Steps 1 to 10
1. Install the bottom bracket to the mounting surface (with screws not included). The lip of the bracket should face down.
2. Place top bracket over the static gland nipple where the lip of the bracket faces up (refer to “Dimensional Data” Figure 1
on Page 6 ). Install bracket nut onto the static gland nipple so that it holds the bracket against the top of the chamber - hand
tighten only. Place the chamber & top bracket assembly onto the bottom bracket. (Upward facing fingers on the lower bracket
straddle the bottom rim of the chamber.) Align the top bracket so that it faces the mounting surface and is in line with the
bottom bracket. Secure the top bracket to the mounting surface (with screws not included).
3. Slowly slide the quartz sleeve into the disinfection chamber, guiding it through the gland fitting until it seats into bottom
center of water purifier. NOTE: Use care to keep the quartz sleeve parallel to the chamber. Angling the quartz sleeve in any
direction could result in the breakage of the quartz sleeve.
4. Place the O-Ring over the end of the quartz sleeve and push the O-Ring down the quartz sleeve until it is seated against the
static gland nipple.
5. Place the Teflon®washer over the quartz sleeve until it rests on the O-Ring.
6. Install the static gland nut over the quartz sleeve and onto the static gland nipple. Be careful when installing static gland nut.
Firmly tighten the static gland nut by hand. Hand tightening will provide the required seal. DO NOT USE HAND TOOLS,
tightening with hand tools is likely to cause the quartz sleeve to break.
7. Insert the lamp part of the way into the disinfection chamber, then attach the lamp socket connector to the lamp; make sure
the connector is fully seated on the ultraviolet lamp. Carefully slide the lamp into the quartz sleeve.
8. Lower, DO NOT DROP, the ultraviolet lamp into the quartz sleeve so that the lamp is resting at the
bottom of the quartz sleeve.
9. Thread the translucent sight port plug (connected to the lamp socket connector) into the static gland nut and hand tighten.
10. Install Grounding Kit following the instructions in the “Grounding Kit Installation” on page 10.
• Plumb unit following the recommended installation in “Unit Installation” Figure 2 on page 7.
• When all plumbing connections are complete, allow water to enter the water purifier at a low flow rate, until the purifier is
full. With the purifier pressurized, it should be checked for leaks. If the unit leaks, make sure that the static gland nut is firmly
tightened. DO NOT use seal compounds to stop the leak. If the leak continues, close the inlet shut-off valve; release the
pressure on the unit and drain. Inspect the quartz sleeve for damage. Be sure that the O-Ring and Teflon®washer are on in the
correct order on the quartz sleeve (not inside the static gland nut).
• Re-pressurize unit and check for leaks. Once it is determined that there are no leaks, the inlet valve can be full opened.
• Once the plumbing hook ups are made, it is good practice to disinfect the “downstream” plumbing between the purfier and
point of use. This is done by introducing chlorine or other disinfectant solution directly into the purifier chamber, a 100 parts
per million of chlorine is suggested. (Continued on Page 10)
IN ORDER TO PERFORM THIS TASK, BE SURE TO WEAR THE FOLLOWING SAFETY
EQUIPMENT: SAFETY GOGGLES OR A FACE SHIELD, AS WELL AS GLOVES

10
• (Continued from Page 9) With the disinfectant solution in the purifier chamber, turn the ultraviolet purifier on.
Open the “down-stream” outlet until a chlorine or disinfectant solution odor is noticed. Close the outlet and allow the
disinfectant to remain in the plumbing for at least three (3) hours. Flush the plumbing with ultraviolet purified water;
allow the water purifier to run for a minimum of 5 minutes before use to ensure no chlorine or disinfectant solution smell
can be detected. This will allow the chlorine or disinfectant solution to be flushed through the pipe.
• Plug the ballast into an approved Ground Fault Circuit Interrupt (GFCI) receptacle. Where a 2-prong or
unprotected 3-prong receptacle is encountered, it must be replaced by a properly grounded Ground Fault Circuit Interrupt
(GFCI) receptacle. Installation must be in accordance with the National Electrical Code and any local codes and ordinances
by a qualified electrician.
Avoid exposure to direct or strongly reflected germicidal ultraviolet rays. Germicidal ultraviolet rays
are harmful to the eyes and skin.

To ensure proper operation and safety of your water purifier, your unit must be grounded to a known good ground.
Purpose: To permanently connect a ground wire from the water purifier chamber to a known ground.
Placement: Select a location that is visible as well as accessible. Connect the ground strap to a known ground or a water pipe that
is metallic, with no intervening plastic fittings between it and the power ground. An electrician can measure the resistance between
the water pipe and an electrical outlet ground to ensure your ground selection is correct.
Installation:
1. Wrap the copper strap tight around the pipe and line-up the strap end hole with another hole on the copper strap as well as a
hole on the brass colored “S” clip.
2. Pull strap as tight as possible to ensure contact between the strap and the pipe.
3. Insert the bolt threw both copper holes and into the threaded hole on the brass colored “S” clip.
4. Remove 5/8” of the ground wire insulation and insert into the bolt hole as shown and install the screw.
5. Ensure that the strap is securely fastened to the pipe and that the copper wire is in contact with the screw and bolt.
MAINTENANCE
The water purifier is designed to operate with a minimal amount of maintenance, providing the water quality does not exceed
maximum concentration levels, see “Water Quality” in the “Product Application” section. Ordinary maintenance consists of;
• Lamp replacement is recommended every 10,000 hours of operation, approximately 12 months of continuous service.
• Cleaning of the quartz sleeve, when conditions warrant. It is recommended that the inspection of quartz sleeve be performed
after one month of use. If quartz sleeve is found to be coated (not clear), then frequency of cleaning must be done more often.
Deposits or discoloration on the surface of quartz sleeve are caused by excessive levels of the subject contaminant within
the water that is in contact with the quartz sleeve. Most deposits on the quartz sleeve are caused by an excess of calcium
(hardness), iron or manganese. Table 1 on Page 4 lists the maximum recommended concentration of these minerals in the
water that passes through the ultraviolet purifier. If you encounter difficulty due to deposits on the quartz sleeve, your dealer
will be able to recommend suitable pretreatment to reduce or eliminate the offending contaminant. If quartz sleeve is clean
(clear) then frequency of cleaning may be extended.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to temperatures below
• Contact factory with questions.

insPeCtion
1. Regularly inspect the water purifier to ensure that the germicidal lamp is still in operation.
SureliteTM Electronic Ballast designed specifically for the UltimateTM line of water purifiers, includes an LED that
provides visual indication (Green and Red LED Indicators) of the germicidal ultraviolet lamp operation and a PromateTM
Audio Alarm that alerts the user to lamp failure. The Electronic Ballast does not indicate the level of ultraviolet intensity or
transmission through the water.
2. To ensure proper operation of the water purifier, regular biological testing of the purifier output water should be performed
on a schedule recommended by local public health authorities, or at minimum; at installation, quarterly for the first year of
service and annually, at lamp replacement, for the life of the water purifier.
3. Additional testing should be performed whenever modifications, change or additions are made to plumbing system, pumps,
well source water etc. to ensure adequate disinfection under new condition.
4. As with any water purifier installation, routine maintenance is necessary to ensure your equipment is operating correctly.
Regular inspection must also include the inspection of the ground to ensure grounding wires are secure to both the water
purifier and grounding point as originally installed. Regular inspection must also include confirmation that approved ground
fault circuit interrupt (GFCI) receptacle is still operational and that water purifier is plugged into this GFCI. Any components
which are damaged, or broken should be replaced.

DisPosal of merCury aDDeD lamPs
Germicidal ultraviolet lamps, like standard fluorescent lamps contain small amounts of mercury. Mercury added
lamps should not be placed in the trash. Dispose of properly. For further information regarding the disposal and
recycling of lamps containing mercury, along with Federal and State requirements visit www.lamprecycle.org. For
more information on germicidal ultraviolet lamps, visit Ultraviolet.com or BuyUltraviolet.com.
OPTIONAL ACCESSORIES
SENTRYTM Safety Sensor: Indicators provide constant visual monitoring of normal operation. In the event of ballast or lamp
failure the safety sensor indicates an alarm condition. The safety sensor is capable of operating an optional audio alarm
and/or solenoid valve.
PromateTM Time Delay Mechanism: Provides a 2-minute warm up period during which the ultraviolet lamp achieves its full
germicidal output before the water is allowed to flow through the water purifier. The time delay mechanism is used in conjunction
with, and is electrically connected to the Solenoid Valve.
PromateTM Solenoid Valve: Operated in conjunction with the Safety Sensor or Time Delay Mechanism, this valve prevents water
flow through the water purifier when an abnormal condition is detected or in the event of power failure.
PromateTM Elapsed Time Indicator: A non-resettable display of the water purifier operating hours. Useful for scheduling and
recording maintenance and lamp replacement.
PromateTM Safety Goggles: Safety eyewear should be used as general-purpose safety protection and for additional shielding
from ultraviolet rays.
PromateTM Face Shield: Adjustable headgear and lightweight visor provides eye and face protection from
germicidal ultraviolet rays.

Ballast No. 10-0505B Has Lamp-out Protection
If power is applied to the ballast without a lamp connected to the circuit or if the lamp fails, the ballast’s lamp-out protection
will prevent the ballast from operating, and a red LED light will illuminate and audio alarm will sound. To reset: disconnect the
ballast from power and reconnect or replace the lamp. The ballast must remain disconnected from power for (2) minutes to
reset. After 2 minutes restore input power, ballast should resume proper operation.
The equipment that this ballast is used with requires connection to a known good ground. It is the User’s
responsibility to ensure that their equipment is properly grounded in compliance with the National Electrical Code and any
applicable local codes. Equipment wiring and hook up should be performed by a qualified, licensed electrician. Failure to comply
with this requirement could result in serious injury or death.
