Safety Instructions
Safety Instructions
WARNING: To guard against injury, basic safety precautions should be observed, including the
following:
1. Read and follow all safety instructions.
2. DANGER: To avoid possible electric shock, special care should be taken since water is
present near electrical equipment. Unless a situation is encountered that is explicitly
addressed by the provided maintenance and troubleshooting sections, do not attempt
repairs yourself. Instead, please contact our technical support division.
3. Ultraviolet lamps, and the sleeves they are housed in, are constructed of quartz tubing.
Quartz tubing is very fragile and easily fractured. Do not strike, bend or apply pressure to
this material or it will break. Broken lamps or sleeves can cause serious cuts and are not
covered under the warranty. Discard lamps and sleeves according to the requirements of
your local laws.
4. Cleaning chemicals used for cleaning the sleeves may cause burns. Wear protective
clothing and protective eyewear when using these materials. Aer cleaning, rinse the
system components thoroughly with clean water. Always follow the safety precautions
recommended by the manufacturer of the cleaning solution.
5. Operate the system only if the chamber is completely filled with flowing water.
Intermittent operation of the system requires that a minimum amount of water flows
through the system in order to cool the lamps. Ignoring this will damage the lamps,
ballasts, and electrical systems.
6. Connect this system only to AC power that conforms to the system rating as regards
voltage and voltage specification.
7. Carefully examine the UV system aer installation. It should not be plugged in if there is
water on parts not intended to be wet. Specifically, there should be no leakage from the
quartz seals or water inside the quartz sleeve.
8. Do not operate the UV system if it has a damaged cord or plug, if it is malfunctioning or
if it is dropped or damaged in any manner.
9. Always disconnect water flow and electrically unplug the UV system before performing
cleaning or maintenance activities.
10. Do not use this UV disinfection system for any other purpose other than disinfection of
water. The use of attachments or accessories not approved, recommended or sold by the
manufacturer may cause an unsafe condition.

System Overview
11. Intended for indoor use only. Do not install this UV disinfection system where it will be
exposed to the weather or to temperatures below freezing. Do not store this system
where it will be exposed to temperatures below freezing unless all water has been
drained from it and the water supply has been disconnected.
12. All repairs are to be done by a qualified tradesperson only.
13. De-pressurize and drain the UV reactor. Pressure must be relieved from the system prior
to any maintenance, to prevent damage to the equipment or personal injury.
WARNING: THE UV LIGHT GIVEN OFF BY THIS UNIT
CAN CAUSE SERIOUS BURNS TO UNPROTECTED EYES
AND SKIN. NEVER LOOK DIRECTLY AT AN ILLUMINATED
UV LAMP. WHEN PERFORMING ANY WORK ON THE UV
DISINFECTION SYSTEM ALWAYS UNPLUG THE UNIT
FIRST. NEVER OPERATE UV SYSTEM WHILE THE UV LAMP
IS OUTSIDE OF THE UV CHAMBER.
System Overview
The Puretec RI-HF Series is designed to treat water at specified flow rates as outlined in the
technical specification sheet. All units are provided with three main components, specifically
the ultraviolet reactor chamber, the main control panel, and the UV intensity sensor.
UV Reactor
The reactor chamber is manufactured from stainless steel 316L and is electropolished and
passivated. The lamp is housed within a quartz sleeve to prevent direct contact with the fluid.
The chamber is also fitted with a UV intensity sensor. This UV intensity sensor measures the
absolute UV Intensity and determines that the system is operating effectively. It is located
in a sealed sanitary housing so that it can be removed for maintenance without draining the
chamber.
The Puretec RI-HF Series systems use lamps which are of a special high intensity, high output
and amalgam germicidal type. The chamber is designed to mount and should be secured to a
suitable support.

System Layout
Fig. 1 - System Layout
Note: Diagram above is for representation purpose only and actual system may vary as per specific
model and variant purchased.
Control Panel
The main control panel is made of powder coated steel. The Control Panel houses the main
interface to the UV system and a UV controller. The controller includes a 128 x 64 pixel
graphical LCD display. The control panel is connected to the UV reactor via 3.5 meters of
cable to allow for installation flexibility.

8Installation & Operation Manual Copyright © Puretec Pty Ltd 2022
UV Sensor
Your Puretec RI-HF Series UV system is provided with one UV sensor per unit which can
measure the efficacy of the UV system in real-time and provide feedback either on the LCD or
to a SCADA system via 4-20ma signal or MODBUS.
The UV sensor is mounted within the sensor window located on the wall of the UV reactor.
The UV intensity measured by the UV sensor is continuously displayed on the UV controller in
either a percentage (%), intensity (W/m2) or dose (J/m2). This is user settable.
Standard Electronics
All Puretec RI-HF control panels are equipped with a safety interlock on/off switch. When this
switch is in the on position it will not be possible to open the cabinet. It must be first turned
off.
All Puretec RI-HF control panels include a “remote on/off mode”. This allows the UV lamp to
be turned on or off from a remote location or by command from a PLC. The default mode of
operation is set to local. However, it can optionally be set to “Remote Hardwire” or “Remote
MODBUS” depending on the customer requirement. Refer to the section Remote Module.
The system includes a resettable circuit breaker as a protection device.
A separate fuse is also provided on the controller motherboard as protection. This fuse is
before the 230V output to the ballast contactor and wiper motor.
A 128x64 pixel LCD display along with a 6 pushbutton keypad provides feedback on the
functioning of the UV system and also allows the user to customize the system. Also included
is a built in data logger which can be accessed from this interface.
Overview of The RI-HF Series
Your Puretec RI-HF Series uses ultraviolet light to treat process water in the food & beverage,
semiconductor, pharmaceutical, and other industries requiring high purity disinfected water. It
is also an effective replacement for chemical biocides in the cooling towers and recirculation
loops used by many industries. The simple, effective design makes it suitable for many large
scale applications in industrial water treatment. Unlike chemical treatment, UV does not
require the handling of dangerous substances and adds no toxic compounds to the water.
The sealed and pressurized reactor chamber of the Puretec RI-HF Series has the capacity
for a high volume of water flow. It is a closed system preventing outside particles from
contaminating the treated water. The modular design of the Puretec RI-HF Series makes it
versatile and permits easy access to the equipment.

Factors That Affect UV Disinfection
Factors That Affect UV Disinfection
Ultraviolet light kills bacteria, protozoa and viruses, by destroying their genetic material. The
performance of an RI-HF unit to disinfect water is expressed in terms of reduction of bacteria,
or “kill”. Each system is designed to reduce microorganism counts to a certain allowable level,
which depends on the requirements of the specific application or regulatory requirements. The
dose of UV light available to kill bacteria is measured in microwatt-sec/cm2 or J/m2, which is
equivalent to the product of the UV light intensity and the duration of exposure, or retention
time. Any factor that affects UV light intensity or retention time will affect performance.
Dose = Intensity (W/m2) x Retention Time (sec)
The Puretec RI-HF Series is designed to deliver a dose that takes into account lamp aging.
Quartz Sleeve Condition
To ensure maximum performance from the unit, it is essential that the Quartz Sleeves be
kept clean. If a coating is allowed to build up on the sleeves, the amount of the UV light
transmitted to the water will be reduced.
Treatment Process
Water processing equipment located upstream of the RI-HF unit such as filters, can affect
performance. Different treatment processes produce water with different UV transmittance
characteristics and different observed cleaning frequency patterns.
Flow Rate
The flow rate through the RI-HF unit will determine the retention time, which in turn
determines the delivered UV dose at a given UV intensity.
WARNING: DO NOT UNDERSIZE UNITS. For advise on unit size please speak with Puretec.

10 Installation & Operation Manual Copyright © Puretec Pty Ltd 2022
Guidelines
It is recommended that the UV reactor be installed horizontally to facilitate easy replacement
of the lamp and/or quartz sleeve. The UV system should be installed in an easily accessible
location to simplify maintenance.
NOTE: OPERATING SPACE EQUAL TO OR GREATER THAN THE REACTOR LENGTH MUST BE
ALLOWED ON THE SIDE OF THE REACTOR (TYPICALLY ON THE SIDE WHERE THE LAMP
IS CONNECTED) TO ALLOW FOR THE LAMPS AND QUARTZ SLEEVE TO BE REMOVED OR
REPLACED.
1. Install the equipment in an indoor environment.
2. The ambient temperature in the installation area should be between 10°C and 40°C, with
the relative humidity less than 80%.
3. Insulate the unit from extreme temperatures.
4. Install the chamber horizontally (If mounting vertically first contact Puretec).
5. To avoid trapping air, ensure the outlet is at the highest point.
6. Allow maintenance space around the system, including the reactor length for lamp
removal.
7. Ensure that the UV controller LCD display and keypad on the control panel are at eye
level and easily viewable. Mount the control panel high enough from the floor to ensure
the control panel is protected against water flooding.
8. When mounting the control panel on the wall, ensure there is at least a 15 cm (6 inches)
of air space around the sides of the panel for sufficient cooling of the inner electronic
components. The more air space there is around the control panel the more efficient the
cooling will be.
9. The maximum cable length between the control panel and the UV reactor is 3.5 m.
Plan the location of the reactor and panel accordingly. DO NOT attempt to increase the
length of this wire in any way.
10. The mains supply cable to the control panel is already pre-wired. This is connected to
the control panel through one of the available inlet ports on the bottom of the panel and
is wired directly to the terminal blocks. In case a longer run of wire is required this wire
may be replaced, but ensure that the correct gauge wire is used and the connections
done in a proper manner. Refer to the electrical wiring diagram for more information.
Guidelines

11
Puretec Radfire RI-HF SeriesCopyright © Puretec Pty Ltd 2022
Installation
1. Pick a suitable location for the UV reactor and the control panel. Make sure that there
is a minimum of clear space at the connection end of the chamber to facilitate lamp
replacement and servicing.
2. Support connecting pipes to UV system to avoid any undue strain on the unit.
3. Avoid vibration from close proximity to heavy equipment or from erratic pumps.
Vibrations from other equipment and/ or water hammering can cause damage to lamps
and quartz within the UV reactor.
4. In an effort to adequately protect the electrical components inside the reactor, the unit
must be connected to an electrical outlet which is protected by an earthing line as well
as a surge suppressor.
5. In case the quartz sleeves have shipped separately, install the sleeves following the
instructions in the section relating to quartz sleeve installation and removal.
6. Once the reactor is securely mounted, plumb the inlet and outlet ports to the supply and
delivery lines with the appropriate connections. When making connections, be sure not to
drop anything into the reactor chamber that may damage the quartz sleeves/lamps or
contaminate the reactor.
7. Aer all connections are made, SLOWLY turn on the inlet valve and SLOWLY fill the
reactor chamber with water. Once the chamber is full, check for leaks from the fittings.
Especially check for any leaks from the quartz sealing nuts. If a leak is evident,
drain system and reconnect the fittings.
8. The system should now be thoroughly flushed to clean out any particulate matter that
may have entered the reactor chamber during installation as well as flushing out any air
that may have accumulated during the “filling”of the reactor.
WARNING: SUDDEN OPENING OF THE INLET FLOW MAY SERIOUSLY DAMAGE UV LAMPS
OR QUARTZ SLEEVES.
9. Secure the control panel making sure the panel is mounted within a 3.5 meter wire run
from the connection end of the reactor chamber.
10. Install the UV lamps as described in the section relating to UV Lamp installation and
removal on page 27 and make all the necessary lamp connections. Do not forget to
connect the earthing wire to the earthing stud on the UV reactor using the provided
earthing nut.
11. Carefully install the sensor assembly into the sensor window on the reactor housing by
first inserting the sensor o-ring and then the sensor itself. Lock the sensor into place
using the provided lock nut. Attach the sensor cable to the sensor. Refer to the section on
UV sensor installation/removal on page 33.
12. Next, plug the reactor into the appropriate electrical outlet and power up the system.
13. Follow the startup instructions in the next section.
Installation

12 Installation & Operation Manual Copyright © Puretec Pty Ltd 2022
System Startup
Allow the UV reactor to fill slowly with water and ensure a running flow of water through the
reactor.
Once the water is flowing, turn on the UV system by using the power switch on the front of
the control panel.
CAUTION: NEVER OPERATE THE UNIT WHILE EMPTY OR WITHOUT FLOW FOR AN EXTENDED
PERIOD. OPERATE THE SYSTEM ONLY IF THE CHAMBER IS COMPLETELY FILLED WITH FLOWING
WATER. INTERMITTENT OPERATION OF THE SYSTEM REQUIRES THAT A MINIMUM AMOUNT OF
WATER FLOWS THROUGH THE SYSTEM IN ORDER TO COOL THE LAMPS. FAILURE TO DO SO
CAN SEVERELY DAMAGE THE UV LAMPS AND CONNECTORS.
On start up the display will show a few cascading screens (see start up section - pg. 28).
The system will indicate that the status is STARTING on the third screen. The system will not
register any alarms until this warm-up timer has expired (90 Seconds). This feature prevents
any false alarms from registering while the system is warming up.
If no alarms are registering aer the system has warmed up and RUNNING message is
indicated in the status line, water for disinfection may be allowed to pass through the
chamber.
For more information on startup and operational messages on the UV controller refer to the
section on Using the UV Controller.
Sensor Calibration
In case of a new installation or when the lamp is replaced with a new one, it is important to
reset the sensor calibration settings. This must also be performed in case a new sensor is
being fitted to the system.
Follow the procedure in the section on Calibrating the UV Intensity.

UV Lamp Replacement
The RI-HF UV lamps are mounted inside the UV reactor. Each UV Lamp is housed within its
own protective quartz sleeve, which protects it from water flow. The lamps and sleeves are
supported by the quartz sleeve holder inside the reactor. The entire lamp and then quartz
sleeve can be removed for service.
The RI-HF UV germicidal UV lamp is a low-pressure, high-intensity amalgam lamp, with
preheating to improve lamp life.
The frequency of UV lamp replacement will depend on various factors such as:
• Water temperature, max operating temperature: 45°C
• Frequency of switching lamps ON and OFF
• Total operating time of the lamps. (the maximum operating hours for the lamp is 12,000
hours)
NOTE: DO NOT CYCLE LAMPS ON/OFF MORE THAN THREE (3) TIMES PER 24-HOUR
PERIOD. CYCLING OF LAMPS MAY RESULT IN PRE-MATURE LAMP FAILURE AND VOID
THE WARRANTY.
Use only genuine quality replacement parts from Puretec. Using any non-authorized lamps,
quartz sleeve or spares in the UV system can affect the performance of the system and void
the warranty.
Removing the Lamp
To replace the lamp, there is NO need to disconnect the system from the water supply, or to
drain the water from the reactor chamber. Lamp replacement is easy requiring no special
tools.
ENSURE THAT YOU DISCONNECT THE MAIN POWER SOURCE AND ALLOW THE UNIT TO
POWER DOWN BEFORE PERFORMING THIS OPERATION.
Once that is done follow the instructions below to remove the UV lamp from the reactor.
Note: Diagrams below are for representation purpose only and actual system may vary as
per specific model and variant purchased.
1. Orient yourself with respect to the chamber so that the
side with the lamp cable is facing you.

2. Remove the nut and star washer holding the
earthing ring in place and disconnect the wire
(optional if your model includes this).
3. Loosen the cable gland on the sealing nut end
cover and slowly unscrew the end cover from the
quartz sleeve sealing nut.
Now gently pull out the lamp harness and extract
the lamp connector and UV lamp assembly from
the UV reactor.
WARNING: AS THE LAMP MIGHT STILL BE
VERY HOT, PLEASE TAKE CARE BY USING
GLOVES OR OTHER PROTECTIVE GEAR.
4. Once you can visually see the lamp, separate
the lamp from the connector by pulling them
apart. Do not try twisting the connector as it
will break. While it is OK to touch the ceramic
ends of the lamp, avoid touching the UV lamp
“glass” with your fingers.
WARNING: TWISTING THE LAMP
CONNECTOR OR PULLING IT FROM THE
WIRES WILL BREAK IT.
5. Carefully remove the lamp from the reactor
chamber taking special care not to angle the lamp
as it is removed. If the lamp is removed at an angle,
pressure will be applied on the inside of the quartz
sleeve, causing the sleeve to fracture and break.
UV Lamp Replacement

18 Installation & Operation Manual Copyright © Puretec Pty Ltd 2022
Installing The Lamp
To install the UV lamp back into the reactor, follow the instructions shown above in a reverse
manner.
If the lamp life hours equals the system run hours the “W:REPLACE LAMP” alarm will be
displayed on the UV controller indicating a fault condition. Once the new lamp has been
installed you can reset the elapsed time. To perform a lamp replacement in the UV controller
refer to the section Performing a lamp replacement.
Cleaning The UV Lamp
The UV lamp should be handled with powder free gloves. To remove accidental finger marks
clean the UV lamp with isopropyl alcohol. Ensure the lamp is cool before doing this.
Quartz Sleeve Replacement
Each RI-HF UV lamp is contained within its own quartz sleeves. The open ends of the
sleeves are sealed against the UV reactor end plate by means of an O-ring compressed by
the sealing nut. The quartz sleeves are made of clear fused quartz with a high level of UV
transmissibility.
If the quartz sleeves become scaled or dirty, they can be removed and cleaned by following
the instructions below.
Removing The Quartz Sleeve
Before starting to remove the quartz sleeve ensure the following:
• Shut off the water flow through the UV reactor chamber. Isolate the UV reactor.
• Turn the power OFF at the control panel.
• Relieve the water pressure and drain the water from the chamber through the drain /
valve provided on the UV reactor bottom.
Once this is done follow the instructions below to remove the quartz sleeve.
Note: Diagrams below are for representation purpose only and actual system may vary as
per specific model and variant purchased.
1. If the lamp is in the system, remove the lamp
and carefully set it aside as described in the
lamp removal section.
Quartz Sleeve Replacement

19
Puretec Radfire RI-HF SeriesCopyright © Puretec Pty Ltd 2022
2. Insert the provided guide rod which helps in the
removal of the quartz sleeve.
In case the guide rod is misplaced or
unavailable, use any PCV rod with a length of
approximately 2 meters and outer diameter of
23 mm. PVC electrical pipes are suitable.
3. Once the guide rod is fully inserted into the
chamber ensure that there is a small portion of
the rod emerging out from the opposite end of
the reactor assembly.
4. Unscrew the quartz sleeve sealing nut by
rotating it in a counter clockwise direction. Do
the same at the other end of the reactor.
5. Remove the quartz sleeve sealing O-ring from
the quartz sleeve and store it carefully. Do the
same at the other end of the reactor.
6. While holding the provided guide rod in place at
the opposite end, carefully slide the sleeve out
of chamber. In case it is initially tight, gently try
rotating the quartz sleeve while also pulling it
out.
Quartz Sleeve Replacement

20 Installation & Operation Manual Copyright © Puretec Pty Ltd 2022
7. Make sure that the sleeve is not at an angle as
otherwise pressure will be applied on the sides
of the sleeve and against the reactor chamber
causing the sleeve to fracture.
WARNING: USE THE PROVIDED GUIDE
ROD AS A SUPPORT OR ELSE THE QUARTZ
SLEEVE CAN “FALL” INSIDE THE REACTOR
WHILE REMOVING AND BREAK.
Once the quartz sleeve is removed from the system it can either be cleaned or replaced with
a new sleeve as required.
Cleaning The Quartz Sleeve
The quartz sleeve forms the barrier between the UV lamp and the water being treated. It
is essential that the sleeve is kept clean otherwise there will be a reduction of the UV light
which will reduce the effectiveness of treatment.
• Puretec SC1000 UV Sleeve/Scale Cleaner can be used for cleaning the sleeves.
Steps
1. The quartz sleeves should not be handled without gloves (use only powder free gloves).
2. Spray the outside of the quartz sleeve with SC1000 and wipe with a lint-free cloth.
3. Clean the interior of the quartz sleeve with SC1000 if there are markings on the inside
surface.
Installing The Quartz Sleeve
Install / reinstall the cleaned or new quartz sleeve in reverse order.
Carefully slide the quartz sleeve into the reactor through the quartz sleeve socket until it
is locked into place in the internal quartz sleeve holder. Ensure that the sleeve is inserted
straight and not at an angle as doing so will put pressure on the wall of the sleeve and
can cause it to crack.
DO NOT FORGET TO INSTALL THE QUARTZ SEALING O-RING ONTO THE SLEEVE
UNTIL IT RESTS AGAINST THE QUARTZ SLEEVE SOCKET BEFORE RETIGHTENING
THE SEALING NUT.
PURETEC RECOMMENDS INSTALLING NEW QUARTZ SEALING O-RINGS EVERY
TIME THE QUARTZ IS REMOVED OR REPLACED.
