Elements to identify the HX Standard Monitoring
System are:
1. UV LED Operational Display
2. Main Power Switch
3. Running Time Meter
4. Integrated Monitoring System
5. Lamps Operational - optional
6. Lamp Out Alert - optional
Fig. B STANDARD CONTROL PANEL
UV Operational Display: FOR NEMA RATED CABINET
To verify the status of the UV lamps, the LED display gives the operator a visual
indication of the lamp status. When the UV lamp is “ON”, the LED will illuminate.
When “OFF”, the LED will not illuminate. Should any UV lamp fail to operate, the
corresponding LED light will automatically turn “OFF”.
Each UV lamp is numbered at the end of the treatment chamber and the
corresponding LED light carries the same number on the display panel.
Main Power Switch:
The Main Power Switch isolates all electric power to the unit.
Running Time Meter:
Each of the UV units is furnished with a Running Time Meter that cannot be reset.
It is used to determine the number of hours on the equipment and for
maintenance. It is very important to record the running time hours and lamp
maintenance.
Lamps Operational & Lamp Out Alert:
For remote monitoring of the UV lamp status, the Lamp Out Alert option is
available. The printed circuit board continuously monitors the lamp status. When
one or more lamps are out, a SPDT contact is available for customer interfacing
during Lamp Out Condition. The contact will enable interfacing into a central
monitoring system (PLC, DCS, etc). During the lamp out fault condition, a visual
31 2

indicator lamp will illuminate RED on the front panel. The Lamp Out Alert for 4
lamps and above units are equipped with a 3 minute time delay. During the first 3
minutes of operation, the circuit will ignore any lamp out condition. The delay
allows time for the proper warm up of the lamps and prevents false alarm
conditions.
If the water system is not designed with any central monitoring system or local
alarm, then the Lamp Out Alert is not necessary. There is always local display of
the lamp status via the standard LED display.
Depending on the system design, a lamp(s) out condition may require immediate
action. This will be based upon the sizing of the equipment, and if any
redundancy is built into the system. Therefore, in a Lamp Out Condition, the
action of the operator will be based upon the overall design.
Integrated Monitoring Station:
The Aquafine®UV Integrated Monitoring System consists of 3 basic components:
the Monitoring Station, the Detector and the Cable with connector.
The corresponding labels identify the different controls. The use of each of these controls
is described in the Monitoring Station Operation section. See page 20.
Fig. A FRONT VIEW OF THE MONITORING STATION
The backside of the Monitoring Station is not accessible to the user after the unit is
installed. During installation, the authorized technician must connect different inputs and
outputs and select the proper position of some switches depending on the installation and
unit requirements. See Fig. B.
NOTE: The UV Monitoring System is not a UV Lamp replacement tool, nor can it be used as a
dosage meter. Degradation of the UV lamps, facility power variation, quartz sleeves, water
temperature, water transmission, and general changes in water quality, will affect the readings. It is
a useful maintenance tool used to determine UV lamp replacement and/or quartz sleeve cleaning
requirements. However, if set-up and monitored properly, it can also give insight into potential
system shortfalls or changes in water quality.

The following are the guidelines and procedures for installing the Optima HX and HX-U
series.
INSTALLATION GUIDELINES:
Location
A) Install the UV treatment unit in a horizontal position in a sheltered, well-
ventilated area. Ambient temperatures surrounding the unit should be
between 35°F (2°C) and 110°F (43°C). Operating water temperature should
be between 40°F (4°C) to 80°F (27°C). Should your requirements differ, please
contact your local Aquafine®representative or Aquafine®Customer Service.
B) 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 related pipes and fittings. Allow
sufficient service access clearance.
C) Limit overhead piping load to 25 lbs (11.3kg), for 2” & 3”, 50 lbs (23kg), for 4”
and 75 lbs (34kg), for 6” or above. 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.
D) All units are rated for a maximum operating pressure of 150 psig (10.3 bar).
E) Ultra pure water users have reported that over time, exposure to ultraviolet
light may phytochemically degrade nonmetallic piping materials, including
most or all fluoro-polymers, resulting in a material breakdown and/or structural
failure. Should your water application and piping material be so classified, we
recommend that you install “UV light traps” to isolate any 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 non-
metallic piping. Should you require any additional assistance, please contact your
local Aquafine®representative or call customer service.
F) Please note the clearance requirements for the replacement of UV Lamps and
quartz sleeves. See page 14 “Do’s and Don’ts”, section H.

14
Electrical Power
A) The power requirement for each unit depends on the number and type of lamp
used in the treatment chamber. The overall power consumption of each unit is
indicated on the equipment nameplate decal on the unit. The unit’s main fuse
provides primary over-current protection.
B) The units (240 VAC incoming power) require a single phase, grounded neutral
source. If the unit needs to be powered by a 120V AC or 208V AC supply, an
externally mounted step up transformer can be provided.
a) If the external transformer is factory installed local to the electrical
enclosure, the secondary terminations are factory wired by
Aquafine®.
b) If the external transformer is required, the transformer primary
connections to the customer’s incoming power shall be made in
conformance to the local codes and be consistent with good
electrical practice.
c) UV performance is line voltage sensitive. Line voltage should be
+5% of rating shown on the electrical nameplate decal. Voltage
outside these limits will affect the performance of the UV equipment.
d) All power and control wiring to be done per enclosed wiring diagram.
HX AND HX-U UNIT INSTALLATION & OPERATION DO’S AND DON’TS:
Do’s
A) Install the UV treatment unit in a horizontal position. The UV treatment
chamber should be firmly mounted and secured. For units with remote
enclosures (HX-U), suitably rated fasteners should be used.
B) Provide ample ventilation. Ambient temperatures surrounding the unit should
be between 35°F(2°C) and 110°F (43°C).
C) Protect the equipment from the environment. Do not expose the equipment to
direct water spray.
D) Verify the location is free from vibration, which could be caused by proximity to
heavy equipment and erratic or improper pumps. Excessive vibration will
damage internal electrical components and cause premature failure of the UV
lamps.
E) Install a drain valve and pipe to drain.
F) Install sample port valves, if required.
G) Provide isolation valves on the inlet and outlet nozzles. Isolation valves will
allow safe maintenance of the equipment.
H) Allow at least 36” of clearance for 30” units or 72” of clearance for 60” units on
the lamp-changing end of the unit. Clearance for servicing the electrical panel
should be allowed.
I) Support all piping to the unit. Limit overhead piping load to 25 lbs (11.3kg), for
2” & 3”, 50 lbs (23kg), for 4” and 75 lbs (34 kg), for 6” or above.
NOTE: It is imperative that the unit be properly grounded for safe and proper operation. FAILURE
TO PROPERLY GROUND THE UV TREATMENT UNIT AUTOMATICALLY VOIDS ALL
EQUIPMENT WARRANTY.

15
J) 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.
K) Provide an electrical disconnect switch to the unit if it is not supplied with the
unit. During service and maintenance, the electrical power must be removed.
L) Operate the equipment within +/- 5% of 240vac.
M) Interface the Low UV, High Temperature, or Lamp Out Alert Alarm relays to
any system monitoring station.
N) After installation of the quartz sleeves, always pressure test the system prior to
installation of the UV lamps and applying electrical power. All leaks should be
repaired. During pressure testing, do not stand in a direct line with the quartz sleeves.
O) Before start-up, flush the UV unit and discharge piping to rinse out any debris
left from installation.
P) The UV treatment chamber should be filled with water. The flow of water
during the initial filling should not exceed 50 GPM. Failure to comply may result
in quartz sleeve breakage.
Q) While the equipment is in normal operating mode, check to see that there is
airflow at the cooling fan intake and exhaust ports. Depending upon the
model, there are generally one or more exhausted fans that should be
cleaned and maintained. Some units have mesh filter, which should be
cleaned frequently, depending upon the operating environment.
Don’ts
A) Do not exceed maximum operating pressure of unit.
B) Do not exceed the maximum flow rate of the model.
C) To maintain standard rated performance, do not allow the inlet water
temperature to exceed 80°F (27°C). Units should not be operated with water
temperatures exceeding120°F (49°C). For applications between 80
° F (27 ° C) and
120
° F (49 ° C), contact Aquafine®Customer Service.
D) For heat sanitization it is recommended that stainless steel compression nuts
be used in place of CPVC compression nuts. The selection of the Elastomer
should be considered.
E) Never allow operating water temperature to exceed 120°F (49°C). Permanent
damage can be caused to the UV lamp(s), electronic ballast and related
components above this temperature. Operating the ultraviolet unit above the
defined temperature through the chamber automatically voids the warranty.
Elevated temperatures cause the UV lamp(s) to lose effectiveness. The heat
can permanently damage the ultraviolet lamp(s). The heat can also damage
the lamp ballast and related instrumentation.
F) Do not exceed 3 “ON/OFF” cycles per 24-hour operation. Excessive cycling of
the unit will prematurely age the UV lamps.

16
QUARTZ SLEEVE INSTALLATION:
The quartz sleeves designed for this series are open on both ends. The following are the
guidelines and procedure for quartz sleeve installation.
1. Turn off all power to the unit.
2. Wear clean cotton gloves to prevent contamination of the quartz sleeves.
3. Carefully remove each quartz sleeve from the factory packaging. Handle
these with care, as they are fragile.
4. Visually inspect all quartz sleeves for cracks or other damage. DO NOT install
damaged quartz sleeves.
5. Remove the socket cover on the end of the treatment chamber. Put the O-
rings and compression nut tool in a safe location.
6. Remove all compression nuts.
7. A PVC pipe is provided for installing the quartz sleeves. Slide the PVC pipe
through the threaded nipple and push through the second endplate nipple.
Repeat for all quartz sleeves.
8. Place the end of the quartz sleeve over the PVC pipe, into the threaded nipple
and slowly push the sleeve into the chamber through to the second endplate.
Repeat for all quartz sleeves. For HX and HX-U units with operating flow
above 1,000GPM, some resistance may be felt from the support Teflon
bushing.
9. Install the compression nut and O-ring by placing the O-ring into the internal
relief of the compression nut, below the threaded area.
10. Place the compression nut and O-ring onto the end of the quartz sleeve until
the end of the quartz sleeve touches the end of the compression nut. Some
pushing and twisting may be required. Deionized water may be used as a
lubricant.
11. Tighten the compression nut approximately ½ turn after the threaded nipple
and O-ring make contact. DO NOT OVER TIGHTEN.
12. Repeat this procedure for the second endplate.
13. Slowly pressurize the system and fill the chamber with water to check for
leaks.
14. If there are leaks in any compression nut assembly, depressurize the system
and use the compression nut tool to slightly tighten the leaking compression
nut assembly.
15. Retest until a leak-free installation is verified.
16. You are now ready to install the UV lamps.

17
ULTRAVIOLET (UV) LAMP INSTALLATION:
Once it has been verified that there are no leaks in the system, the unit is ready for UV
lamp installation.
1. Remove all the 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. This is very important; if not installed
properly, lamp or quartz sleeve breakage will occur.
7. Twist the lamp into the locking mechanism of the compression nut. This
ensures that the lamp is secure within the quartz sleeve.
8. Each lamp socket is identified with a number that corresponds to each lamp
position marked on the endplate. 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. Install the compression nut caps and the compression nuts on the second
endplate and tighten by hand.
NOTE: If the unit is supplied with a monitoring system, recalibration must be performed after the
first 100 hours of operation on new UV lamps, both at the time of installation and each time the UV
lamps are replaced. Failure to correct may result in incorrect readings of relative UV irradiance
(percentage).

18
POWERING UP:
Prior to turning on the UV unit, the following must be verified:
1. The UV chamber should be filled with water. The flow of water for the
initial filling should not exceed 50 GPM. Failure to comply may result in
quartz sleeves breakage.
• Ensure 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 cover is secured to the end of the UV treatment unit.
• 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 LED Operational Display. For non-Aqualogic 2000®
units, the LED should illuminate yellow when the lamp is on. For the
Aqualogic 2000®units, the Lamp Status LED should change from RED to
GREEN. GREEN indicates the lamp is “ON”, RED indicates the lamp is
“OFF”.
4. Connect the Monitoring Detector Cable, if equipped.
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. PROLONGED FLOODING OF THE QUARTZ SLEEVE AND COMPRESSION NUT CAVITY CAN
CAUSE PREMATURE FAILURE OF THE LAMP CONNECTOR CABLE AND MAY RESULT IN A MELTDOWN OF THE
CABLE INSULATION.

OPERATIONAL GUIDELINES:
1) Release the pressure in the UV treatment chamber before attempting to
remove the protective covers and sealing items.
2) Disconnect all power to the UV unit before servicing. The unit operates on
high voltage and should only be serviced by qualified personnel.
3) Do not allow the unit to overheat by operating without water flow. Standard
flow rates are based on water temperatures of 40°F to 80°F. For applications
outside these temperatures, contact customer service for assistance. In no
case should the water temperature be below 35°F or above 120°F. For heat
sanitization above 170°F, stainless steel compression nuts and Viton
elastomers are recommended. With these components, sanitization up to
250°F (121°C) is allowed in a non-operating state.
4) Intermittent operation is allowed as long as the water temperature does not
exceed 120°F; optional devices (T-120 or monitoring stations) are available to
prevent this problem. Should the unit be used for batch flow operations, it can
be turned “ON” and “OFF” manually. Make sure the unit is allowed to warm
up for at least 3 minutes before use, and make sure the unit is turned “OFF”
after each session.
5) Do not allow the flow rate to exceed the maximum rated capacity.
6) DO NOT electrically cycle the UV unit more than 3 “ON/OFF” cycles in a 24-
hour period. Cycling more than this will reduce End-Of-Life (EOL) output
and/or cause premature lamp failure.
NOTE: DO NOT look at the lighted blue UV lamps. DO NOT operate the UV lamps outside of the
UV treatment chamber. EXPOSURE CAN SEVERELY BURN AND DAMAGE EYES AND SKIN!

INTEGRATED MONITORING SYSTEM for HX or HX-U series:
The Monitoring Station has the capability to display continuously the level of irradiance
detected by the sensor in irradiance units (µW/cm2) or in percentage value (%). See Fig. A
# 8.
In addition, the Monitoring Station also reports the current temperature value of the water
either in degrees Celsius or Fahrenheit. See Fig. A #7.
Fig. A INTEGRATED MONITORING SYSTEM DISPLAY
1. Liquid Crystal Display (LCD)
Displays irradiance values in µW/cm2(from 0 to 5,000 with 1 µW/cm2
resolution) or in percentage (000.0 to 100.0 with 0.1% resolution) and
temperature values in °F or °C (32.0 to 212.0 °F or 000.0 to 100.0 °F – with
0.1 ° resolution).
2. TEMPERATURE DISPLAY button
Hold down this button to display the water temperature, otherwise the LCD
shows the irradiance value.
3. UV DISPLAY UNITS button
With two fixed positions; this allows the user to toggle between absolute
irradiance values (µW/cm2) or in percentage (%).
4. SET 100% LEVEL potentiometer
By turning this control, the percentage value reported is modified. This control
is normally set each time UV lamps are replaced. The user then may set the
irradiance value detected to 100%. To properly operate this control, the UV
Display UNITS button (3) must be set to show irradiance value in % units.
