10. Operating the unit without water flow.
RBE series
The models in this series contain all electrical compo-
nents in a Remote Electrical Enclosure. This is ideal for
applications where the treatment chamber is outdoors or
subject to washdown, etc. All electrical service and
instrument monitoring can be done at the remote site.
The Remote Electrical Enclosure contains various
electrical components, circuit boards, and all
instrumentation. It is connected to the treatment
chamber via a flexible, watertight electrical cable.
treatment chamber
The UV treatment chamber is comprised of one or more
multi-lamp cylinders. On either end are gasketed end
plates which contain the stainless steel nipples and the
lamp socket retainer assemblies.
Inside each cylinder is a helical baffle that prevents
laminar flow and maximizes the unit’s performance.
The quartz sleeves fit inside the UV treatment chamber
through the holes in the helical baffle. The lamps fit
inside the quartz sleeves. The lamp sockets connect to
the lamps, providing a waterproof seal and a vibration-
proof grip. The socket covers on either end of the
chamber protect the lamp sockets and lamp socket
assemblies.

operating pressure
Standard units are rated for a maximum operating
pressure of 120 psig (8.24 bar).
If your unit has the High Pressure Modification option
(model number suffix “HP”) operating pressure may
increase to 150 psig (10.34 bar).
hot water sanitization
For hot water sanitization (temperatures exceeding
170°F (77°C) up to a maximum of 194°F (90°C)), it is
recommended that stainless steel compression nuts be
used in place of CPVC compression nuts. During hot
water sanitization the S-254 sensor element must be
removed. The selection of the elastomers should be
considered.
remove the plastic dowel(s)
A plastic dowel is placed inside the UV treatment
chamber to secure the baffle during shipping. The 30”
units have one dowel on the left side only and the 60”
units have two dowels -- one on each side.
Remove the compression nut in the twelve o’clock position on
the left side of the UV treatment chamber. Remove and
discard the plastic dowel. Replace the compression nut. You
can then proceed with the installation of the quartz sleeves.
where to install the unit
Install the UV treatment unit in a horizontal position in
a sheltered area with ample ventilation. Ambient
temperatures surrounding the unit should be between
35oF (2oC) and 110oF (43oC). Should your requirements
differ, contact the factory for assistance.
As an ultraviolet UV treatment unit does not introduce
any chemical residue within the water, it is desirable to
install the unit as close as possible to the point-of-use in
order to avoid potential recontamination by discharge
pipes, fittings, etc. The base of the UV treatment unit
should be mounted on suitable support to avoid undue
strain on the unit or your related pipes and fittings.
Allow sufficient service access clearance. In making
your plumbing connections, provide unions, valves,
bypass and drain.
how to protect your unit
The location should be free from undue vibration which
could be caused by proximity to heavy equipment,
erratic or improper pumps. Excessive vibration will
damage internal electrical components and cause
premature failure of the UV lamps.
Limit overhead piping load to 50 lbs (22.7 kg) per
flange. If your piping system is subject to impulse
pressure resulting in a “water hammer” condition, a
surge tank or other means must be provided to remove
this condition, otherwise the extreme momentary
pressure may rupture and fracture the quartz sleeves.
A parts check list was included when this unit
was shipped. Please refer to this list and note
that some parts are small and can be easily
overlooked when discarding packaging.
Depending on the size of the lamp being used, please allow at least
36 inches (92 cm) of clearance for 30-inch units or 72 inches (182
cm) of clearance for 60-inch units on the lamp-changing end of the
unit.

intermittent operation
Never operate the unit without water flow. Permanent
damage is caused to the UV lamps, electronic ballasts
and related components without water flow.
Operating the ultraviolet unit without water flow
through the chamber automatically voids the warranty.
If operated without water flow, the fluid within the
ultraviolet chamber will become hot causing the UV
lamps to lose effectiveness. The heat can permanently
damage the ultraviolet lamps, UV sensor, the lamp ballast
components and related instrumentation.
Should the unit be used for specific batch flow opera-
tions, it can be turned “On” and “Off” manually. Make
sure the unit is allowed to warm up for at least one
minute before use, and make sure the unit is turned
“Off” after each session. Do not exceed 3 on/off cycles
per 24 hour operation.
If you need help to determine the best method of operat-
ing your UV treatment unit under intermittent conditions,
contact your local representative or the factory.
An optional Temperature Safety Control Device is available
to prevent the overheating problems described above.
special piping requirements
for users of ultrapure water
Ultrapure water users have reported that over time,
exposure to ultraviolet light may photochemically
degrade nonmetallic piping materials, including most or
all fluoro-polymers, resulting in material breakdown
and/or structural failure.
Should your water application and piping material be so
classified, we recommend you install “UV light traps”
to isolate any such susceptible material from direct
exposure to the ultraviolet light. Install the UV light trap
to the inlet/outlet of the UV treatment chamber prior to
the connection of any nonmetallic materials. UV light
traps protect nonmetallic piping. Should you require any
additional assistance, please contact your local Aquafine
representative or the factory directly.
wiring the unit
Connect the liquid-tight flex conduit, which contains
the interconnecting wiring harness, into the remote electrical
enclosure through the liquid-tight connector which is
provided. Connect the wiring harness to the terminal block
starting with terminal block assembly A through terminal
block assembly B. (See Wiring Diagram in back pocket of
this manual.) Optional equipment connections are made on
terminal C. Terminal C blocks are included with optional
equipment.
Bring your incoming wiring to the 1/2-inch electrical
knockout in the bottom of the remote electrical enclosure.
Make connections to terminal blocks G, N and L. Terminal
block L is “hot”; N is “neutral”; and G is the “ground”.
Make sure your electrical service matches the specifications
on the electrical name plate decal on your unit. Locate an
“on/off” switch near the unit so the current may be turned off
for servicing.

GROUNDINGOUNDING
OUNDINGOUNDING
OUNDING
IT IS IMPERATIVE THAT THE UNIT BE PROPERLY
GROUNDED FOR SAFE AND PROPER OPERATION.
Failure to properly ground the UV treatment unit automati-
cally voids all equipment warranty.
UV performance is line voltage sensitive. Line voltage
should be +10% of rating shown on the electrical
nameplate decal. Voltage outside these limits can reduce
the performance of the UV equipment.

single-ended lamp design for units
manufactured after January 1, 1999
Once it has been verified that there are no leaks in the system, the UV
lamps are ready for installation.
1. Remove all power to the UV unit.
2. Depressurize the system.
3. Wear clean cotton gloves to prevent contamination of the UV lamps.
4. Carefully remove each UV lamp from the factory packaging.
Handle these with care as they are fragile.
5. Visually inspect all lamps for cracks or damage.
Do not install damaged lamps.
6. Using both hands, slowly insert the lamp into the quartz sleeve
by pushing one end of the lamp with one hand, while continuing
to support the lamp in a level, horizontal position with the other
hand. This is very important. If not installed properly, lamp or
quartz breakage will occur.
7. Twist the lamp into the locking mechanism of the compression nut.
This ensures the lamp is secure within the chamber.
8. Each lamp socket is identified with a number that corresponds to
each lamp position marked on the end plate. Match the lamp socket
and connect to the appropriate lamp.
9. The two pins in the lamp must be pushed down to fit securely into
the pins with the connector.
10. Rotate and screw the lamp socket cap into place. Only hand
tightening is required. Do not overtighten!
11. Repeat the procedure above for the second endplate for the
non-pin lamp ends. Instead of securing the lamp socket lead
assembly to this end of the assembly you will twist on and firmly
secure the fixed Compression Nut Cap to the compression nut
assembled on the quartz sleeve.
CAUTION! Prior to energizing the
ballasts and lamps, ensure there is no
water leaking into the quartz sleeves and
compression nut cavities by properly
installing these components. Even a small
leak can flood a quartz sleeve and
compression nut cavity.
During operation, high voltage is present at the lamp
pins and receptacles of the lamp connectors. Pro-
longed flooding of a quartz sleeve and compression
nut cavity can cause premature failure of the lamp
due to repeated arcing, overheating of the lamp
connector cable, and may result in a meltdown of
the cable insulation.

nut, making sure the number on the socket lead wire and the end
plate correspond.
9. Connect the right side rubber lamp sockets and spring-loaded lamp
socket retainer assemblies onto each lamp. Pay special attention to
match the numbers on the retainer assemblies with the numbers
beside each steel nipple on the end plate.
10. Carefully pull out each rubber lamp socket from each spring-loaded
socket retainer assembly.
11. With one hand, push the rubber socket boot onto the end of each
ultraviolet lamp. When properly attached, a slight “snap” can be
felt, which indicates a proper connection.
12. Carefully slide each lamp socket retainer assembly up and over the
rubber lamp socket boot, until the retainer assembly reaches the
male-threaded portion of the compression nut.
13. Then, turn clockwise until the socket retainer cap bottoms out
against the compression nut. Avoid overtightening.

• With water flowing through the system, ensure that
there are no system leaks and no piping connection
leaks
• All earth ground connections are properly made
• All lamp connections are properly made.
• The socket covers are secured to both ends of the UV
treatment unit.
1. Verify that all incoming power conductors, including the
ground conductor, are properly terminated.
2. Turn on the electrical power to the UV unit.
3. Observe the UV Lamp Operational Display panel. All
yellow lights produce a steady glow after 3 minutes
time. Operate 10 more minutes and recheck. The UV
unit is now ready for operation.
Turn the power off until actual operational start-up
begins.
CAUTION! Rapid successive
cycling of the power to the
ballasts can cause premature
failure of the system
components.

16
UV lamp operational display panel
To verify that all the UV lamps are operating properly, your UV
treatment unit has been provided with a UV Lamp Operational
Display Panel. The panel consists of as many LED indicators as
there are ultraviolet lamps. Each LED indicator is electrically
connected to the lamp circuitry of a specific UV lamp. The LED
indicators are intended to operate “on” when the UV lamps are
also turned “on”.
Should any UV lamp fail to operate electrically, the corresponding
LED will automatically turn “off”.
Each UV lamp is numbered at the end of the UV treatment chamber,
and the corresponding LED light carries the same number on the
display panel; thus, if one or more LED lights fail to operate, you can
easily determine which specific lamp requires attention.
We recommend you monitor the LED Panel daily to ensure proper
performance.
running time meter
Your ultraviolet treatment unit has been furnished with a Running Time
Meter, located on the front instrument panel. This non-resettable
running time meter will log up to 99,999 hours. It is intended to remind
you of the number of operating hours on the equipment, as certain
maintenance functions need to be performed at certain time intervals.
A maintenance log is attached to the unit for your use. It should be kept
current. This provides an immediate maintenance reference: when it
was performed and when the next service is due. Additional service logs
are available from Aquafine, and are intended to be placed on top of the
existing service logs.

model S-254 UV optical sensor
option
The optional S-254 UV optical sensor measures the
relative output of ultraviolet light within the UV
treatment chamber. Degradation of the UV lamps,
fouling of the quartz sleeves, water temperature
fluctuation and increased turbidity of the water will
all affect the sensor reading.
The UV meter assembly and instrumentation setpoint
potentiometers are located on the front of the electrical
enclosure. The peripheral alarm contacts are accessible
from the back side of the meter. A shielded signal cable
connects the sensor meter assembly to the sensor probe.
The sensor probe is located in the sensor port fitting on
the top of the UV treatment chamber in Double-Ended,
High-Temperature (HT) units and in the endplate in
Single Ended units.
All S-254 UV optical sensors are tested and preset at
the factory in free air. Setpoint adjustments are required
at installation and after each subsequent lamp changeout
cycle.

SENSOR ALARM
The S-254 UV optical sensor provides information
about the relative amount of UV passing through the
water. The reading is affected by quartz sleeve fouling
and/or the germicidal lamp efficiency. The UV sensor is
sensitive to, and reflects changes in, UV transmission
when a substantial change occurs in the normal operat-
ing flow rate, temperature, operating pressure, or quality
of the fluid flowing in the system.
When the UV intensity falls below the minimum
standard due to any of the above conditions, the sensor
alarm light (red LED) will come “on” and corrective
action must be taken to optimize the performance of the
UV treatment unit.
1. Examine your system for any significant changes in
normal operating conditions.
2. Check if all UV lamps are electrically operating
and/or need replacement. Verify the quartz sleeves
are clean.
If quartz sleeve fouling has caused the optical sensor
alarm to activate, the quartz sleeves must be cleaned. At
the same time, you must clean the sensor probe quartz
window. Please find this information in the maintenance
section of this manual.

temperature
safety control option*
The Temperature Safety Control consists of a heat-
sensing probe. This device protects against inadvertent
overheating inside the UV chamber, which can damage
the UV lamps and the ballast/LED Display Panel circuitry.
The Temperature Safety Control senses raised water
temperature and assumes the UV lamps are operating
“on” with no water flow.

The device automatically turns the UV lamps “off”
when the water temperature reaches 170ºF (77ºC) and
automatically turns the UV lamps back “on” when the
temperature falls to 150ºF (66ºC).
This temperature spread prevents excessive stop/starts
during no flow conditions, and it protects the UV lamps
and the electrical components from overheating damage.
The temperature probe is located in the end plate. No
operator intervention is required other than periodic
visual verification that the UV lamps (LED Display
Panel) are properly operating during normal water flow
conditions.
* This feature is standard on all High Efficiency (HE)
units.
lamp-out alert indicator option
Lamp Out Alert is an optional accessory package that
activates a relay when a UV lamp fails to operate.
A visual inspection of the LED UV Lamp Display Panel
will indicate which lamp has failed. Dry contacts are
provided for customer connection. The dry contacts are
rated at 3.0 Amps maximum @ 120 volts.

4-20 mA sensor signal option
This option works with the optional S-254 optical
sensor. It generates a 4-20 mA output signal based upon
the relative UV intensity which may be monitored at a
remote control panel or control PC. The customer is
responsible for providing an appropriate 4-20 mA
display instrument and connecting it.

using the LED display
If an LED bulb does not light after you replace a UV lamp, you need
to verify the electrical output of the ballast connected to that specific
UV lamp. This is done by testing the ballast open circuit voltage.
This should be done by an electrician or qualified facilities
personnel. Follow these recommended procedures:
1. Turn power “off” to the UV unit.
2. Remove the socket cover.
3. Identify the “faulty” UV lamp which corresponds to the
number on the LED display.
4. Remove the lamp socket(s) from the “faulty” UV lamp base.
5. Use a voltmeter and set an operating range at >700 VAC.
6. Measure the open circuit voltage:
For single-ended (SE) UV lamps: connect the voltmeter across
the receptacles of the lamp socket.
For double-ended (DE) and high temperature (HT) UV
lamps: connect one end of the voltmeter to one end of the lamp
socket and the other end of the voltmeter of the opposite end of
the lamp socket.
7. Turn power “on” to the UV unit.
8. Record the reading.
9. Turn power “off.”
10. Listed below please find the open circuit voltages for the
various ballasts:
If the voltage reading is zero or a number above or below the
acceptable ranges, this indicates a ballast fault, and the ballast
connected to the “faulty” UV lamp must now be replaced.
If the voltage reading is within acceptable ranges but the LED
does not light, the LED board has failed and needs to be replaced.
Refer to the Replacement Parts Lists in the back of this manual to
identify the proper ballast and/or LED part number.

cleaning the unit
The exterior surfaces of the Aquafine UV unit should be
kept clean as part of routine maintenance. Use a soft cloth
with soap and water or any commercial stainless steel
cleaner. Avoid scratching the Lexan instrument window.
LED status display panel
Monitor the Status Display LED Panel daily.
Immediately replace any failed UV lamp.
UV lamp replacement
Replace Standard UV lamps after 8,000 hours of use. Replace
High Efficiency (HE) UV lamps after 6,000 hours of use.
THIS IS BASED ON NO MORE THAN 3 ON/OFF
POWER CYCLES PER 24 HR. PERIOD.
Please follow all operating requirements outlined in the
warranty section of this manual.
Premature lamp failure or lamp life deterioration can be
expected if the UV unit is cycled on/off more than three
(3) times a day. To replace the lamps, follow the proce-
dures on pages 11-14.
quartz sleeve cleaning
& replacement
As water passes through the ultraviolet treatment unit,
minerals, debris and other substances in the water will
settle and deposit onto the quartz sleeve. This will impair
the ability of the ultraviolet rays to penetrate the water.
CAUTION! Prior to remov-
ing the socket cover to
access the lamps and
quartz sleeves, you must
release all pressure to the
UV treatment chamber.
Drain the chamber if required. Do not
stand in a direct line with the endplate;
observe from the front or back of the
unit.
Recent studies have shown that degradation of the quartz
sleeve from continuous exposure to UV reduces the amount
of UV radiation transmitted into the water stream. Based
on these findings, we recommend the annual replace-
ment of the quartz sleeves in addition to routine
cleaning.
cleaning the quartz sleeves
Visually inspect a quartz sleeve thirty days after use to
see if any debris or film has settled on the outside. If
dirty, follow these procedures:
1. Turn off the water to the unit.
2. Disconnect the electrical circuit.
3. Drain the UV treatment chamber.
4. Wear clean cotton gloves to prevent contamination of
the quartz sleeves and UV lamps.
5. Remove the retainer caps and lamp sockets.
6. Remove the ultraviolet lamps from inside the
quartz sleeves.
7. Using the appropriate compression nut tool, loosen
the compression nuts and carefully remove the
quartz sleeves.
8. Wash the quartz sleeves with mild soap and water
and rinse with clean, hot water.
Should this be insufficient to clean the quartz sleeves,
they should be replaced. To place an order, contact
Aquafine or your local representative. To replace the
quartz sleeves, follow the procedures on pages 8-10.
cleaning the sensor probe
window
1. Shut off the flow and release the pressure.
2. Shut off all power to the UV unit.
3. Remove the coaxial cable by pushing and twisting
the BNC terminal counterclockwise. The connector
will slide off.
4. Twist and pull the probe from the sensor fitting.
5. Use a lint-free cloth with alcohol and very
carefully wipe the lens face on the front of the
probe. Failure to do so may result in false readings.
