1. INTRODUCTION
UV disinfection is an ecient, low cost and environmentally friendly process. UV light kills
pathogenic micro-organisms quickly without leaving any residues, harmful by-products or
aecting the smell or taste of the water.
These units use UV lamps which emit UVC radiation at 254nm which disrupts the DNA in the micro-
organisms, so they are either killed or their ability to replicate is destroyed.
The kill rate depends on the UV dose received by the micro-organisms, i.e. the time that a micro-
organism is exposed to a certain intensity of UV radiation (Wm2). A UV dose of 400 J/m2, is
recognized internationally as a suitable dose to ensure safe disinfection of drinking water.
The disinfection performance of a UV system is determined by the intensity of the UV light, water
flow rate, the optical transmission of the water at 254nm and the geometry of the reactor. The
sizing of the UV system should be based on these parameters. Please contact your UV Guard
representative if you have any queries regarding correct sizing.
As there are no disinfection substances added to water by UV radiation, there are no residual
eects once the water has passed through the UV Reactor.
Only UV Guard Australia Pty Ltd spare parts should be used to ensure proper operation and
performance.
1.1 General Safety Instructions
ELECTRIC SHOCK!
Attention: Dangerous electric voltage is present inside the power supply box and
chamber These instructions must be followed closely to prevent serious personal injuries.
ENSURE EYE PROTECTION IS WORN WHEN SERVICING AND
INSTALLING THIS UNIT!
UV-C radiation is harmful to the eyes and skin! UV lamps should be used only when properly installed
in the irradiation chamber. The UV lamp must never be operated outside the disinfection chamber.
•Make sure this disinfection unit is only used for the intended purpose as described in the
operating instructions.
•This disinfection unit is to be installed properly, according to these operating instructions,
before use.
•Do not use a unit with a damaged electrical lead or plug, a unit with any faulty functions, or a
unit which has been dropped or has been damaged in some way.
•Make sure that the unit is unplugged when it is not being used, before fitting, or removing any
parts, or before cleaning the unit.

5
SLT-Series™
•Ensure the disinfection unit is electrically isolated before:
o Carrying out repairs.
o Cleaning.
o Replacement of the UV lamp
•The unit must be depressurized before maintenance.
•Do not use the UV lamp outside of the UV disinfection reactor.
UV Guard UV lamps are designed for permanent operation to reach their best disinfection
capacity. Frequent switching on and o reduces the life of the UV lamp!
2. ASSEMBLY AND INSTALLATION
Installation should meet the AS/NZS 3500.1 Plumbing and drainage standards at all times.
Installation should be carried out only by qualified technicians.
The Following MUST be Checked Prior to Installation:
•A maximum operating pressure of 800KPa (8 bar or 125 psi) must not be exceeded.
•The maximum ambient temperature is 45оC
•For the SLT12, SLT30, SLT40, SLT75 and SLT80 units, maximum water temperature should not
exceed 40оC. The SLT125 and SLT172 units utilise Amalgam UV lamps and can be operated at
water temperatures of up to 55оC
•The reactor must be plumbed so it remains full of water at all times while the lamp is
operating.
•If the SLT12, SLT30 and SLT40 models are left on during extended periods of no flow, the water
in the reactor will begin to get warm. A tap may need to be run for a few seconds until the
warm water passes.
•The SLT75, SLT80, SLT125 and SLT172 models will produce higher water and UV reactor
temperatures if they are left on during extended periods of no flow. This may damage the
UV lamp due to overheating and cause skin burns if the UV reactor is touched. There is also
the potential for water burns depending on the vicinity of the system to the water outlet. it is
recommended a temperature management valve is installed on the outlet of the reactor of
these UV systems. This is to manage the temperature of the UV reactor and water from getting
too hot (55 degrees). At 55 degrees the valve will open to purge a small amount of water out
of the reactor to either be returned to the source, or dumped to waste. The water flow from
this action will cool the reactor and then closes the valve automatically. The warm water is
replaced by new cool water.
Recommended systems to use a thermal relief valve are the UVG SLT75, SLT80, SLT125, SLT172.
However, thermal relief valves can also be provided for the SLT30 and SLT40 models to prevent
warm water reaching the outlet.

2.1 Installing the Reactor
•Before installation ensure you know which reactor type you are using.
•Make sure that there is enough free space to service the glassware with the reactor (see
Table 1). Otherwise it will not be possible to install the UV lamp and maintain the UV system.
•The reactor is to be fixed by means of the mounting legs, either on the wall or on a mounting
frame.
•The disinfection chamber comes complete with it’s own wall mounting brackets
•The preferred orientation for the reactor is horizontal, however vertical orientation is
acceptable. The in-outlet ports should be pointing up for horizontal installations, or the
outlet should be the top port in vertical installations, to prevent airlocks.
•Refer to Table 1 for the distance from the sealing nut, required for servicing the unit.
•When mounting the chamber, consideration must be made for the weight of the system due
to the stresses associated with pipe work etc.
•The stainless steel chamber and surrounding pipe-work must be properly earthed to prevent
electrolysis/corrosion.
Outlet points should be facing upwards in horizontal
installations, or the outlet should be the top port in vertical
installations to prevent airlocks.

2.2 Quartz Thimble/Sleeve and UV Lamp Installation
DUE TO THE FRAGILE NATURE OF THE QUARTZ, CARE MUST BE TAKEN WHEN HANDLING AND
INSTALLING THE QUARTZ THIMBLE and UV LAMP.
Cotton or powder free nitrile gloves should be worn whenever handling the UV lamp or quartz in
order to prevent finger print marking, which will detrimentally impact UV intensity.
•Remove the sealing nut(s) from the reactor and ensure the O ring seal is removed as well. For
the UVG SLT12, SLT80, SLT125 and SLT172 units remove the blind sealing nut from the blind end
of the chamber as well.
•Take the quartz thimble and wipe it down with the alcohol wipe provided to remove any
grease and finger marks, then dry it. Insert the domed end of the quartz thimble into the
chamber and locate the thimble in its support spring at the far end of the chamber. Failure
to locate the domed end of the quartz thimble into the support spring may result in water
leakage or quartz thimble breakage. For the double ended SLT12, SLT80, SLT125 and SLT172
position the quartz thimble so there is equal amounts of quartz sticking out of each end of the
chamber.
Reactor
Sealing Nipple
Quartz Thimble
For SLT12, SLT80, SLT125 and SLT172
double ended chambers, the quartz
needs to be centered so there is an
equal amount at each end.
For single ended chambers the quartz needs
to be located so there is a maximum of 14mm
protruding from the end of the chamber when
the support spring is fully compressed.
•Apply a generous amount of food grade O ring lubricant to the O ring. This is provided with all
new UV Guard systems. If you are servicing an older system, contact UV Guard for more O ring
lubricant as this MUST be applied.
•Place an O ring over the quartz so the O ring is positioned against the chamber on the sealing
nipple. For the double ended SLT12, SLT80, SLT125 and SLT172 there is an O ring at each end of
the chamber.
O Ring seal
For SLT12, SLT80, SLT125 and SLT172 double
ended chambers, an O ring needs to be
placed over each end of the quartz.
For single/double ended chambers an O ring
needs to be placed around the quartz so it is
against the chamber on the sealing nipple.

9
SLT-Series™
•For double ended chambers the blind sealing nut needs to be screwed on the chamber over
the domed end of the thimble. The open sealing nut needs to be screwed on to the chamber
over the open end of the quartz thimble. The sealing nuts should be tightened to firm hand
tightness. They should not be tightened with a mechanical aid such as multi-grips. Look
through the sealing nut to check the O ring is compressed on to the quartz thimble.
For SLT12, SLT80, SLT125 and SLT172 double ended
chambers, blind sealing nut needs to be screwed
on over the domed end of the quartz.
For single/double ended chambers the
open sealing nut needs to be screwed on
over the open end of the quartz thimble.
•DO NOT INSTALL UV LAMP YET. The UV reactor quartz thimble O ring seal/s now need to be
checked. Allow water to enter the UV reactor until operating pressure is reached. Leave the UV
reactor full of water at operating pressure for a minimum of 15 minutes. Using a torch, inspect
the O ring seal/s and check for water leaks. If a leak occurs, gently tighten the sealing nut/s
until the leak stops.
•Remove the UV lamp from its protective wrapping and wipe down with an alcohol wipe or
cloth soaked in methylated spirits. Do not touch it without protective gloves, care should be
taken not to leave markings of any nature on the UV lamp, as this could have a detrimental
eect on the performance of the UV lamp. Allow alcohol or methylated spirits to dry.
•Insert the UV lamp into the quartz thimble through the hole through the centre of the sealing
nut. If the reactor is installed vertically, NEVER drop the lamp into the quartz thimble, as this
may break the quartz thimble.
•Using a soft cloth, or wearing gloves to hold the UV lamp, push the female 4 pin connector
firmly on to the lamp pins.

2.3 Power Supply Box Installation
The power supply box must be mounted clear of the floor as a precaution against the
ingress of water.
•The power supply box is not designed for remote mounting. Recommended maximum
distance of chamber to power supply box is two (2) metres.
•UV Guard have indoor and weatherproof controllers.
Identify your controller using the part numbers in the
following table to check installation details
For details of how to operate the digital power supply boxes, including how to calibrate the UV
intensity of a new UV lamp see Section 3 – Servicing and Operating.
•Secure earth lug on the designated earth point.
•Insert the power lead into the outlet then turn power on. The UV lamp will ignite and come on,
however it will take between 2 and 5 minutes for the lamp to reach full output.

2.4 Basic Thermal Relief Valve Installation (Option)
This fully automatic valve is installed on the outlet port of the UV reactor and will discharge a small
amount of water to drain or back to a storage tank when the system reaches 55оc. This valve will suit
applications where there are extended periods of no flow, to safeguard the UV system from over-
heating, ensuring optimum UV output is maintained and preventing UV lamp damage.
•Install the basic thermal relief valve directly onto the
outlet port of the UV Reactor using teflon sealing
tape to seal the threads. The red barbed plastic
fitting must be pointing down below the level of the
outlet to ensure that air is not trapped in the valve.
•Connect the outlet piping to the output of basic
thermal relief valve using teflon sealing tape to seal
the threads.
•Connect the clear plastic tubing supplied to the
red barbed plastic fitting on the basic thermal relief
valve.
•Secure the other end of the plastic tubing to a
suitable drain or feed back to storage tank.

3. SERVICING AND OPERATING
It is vital that only UV Guard spare parts are used in your UV disinfection system. This is to ensure that
the correct level of treatment is being applied to the water. Using non UV Guard spare parts may
result in an un-safe level of water treatment and may cause operational problems such as leaks.
DUE TO THE FRAGILE NATURE OF QUARTZ, CARE MUST BE TAKEN WHEN HANDLING AND INSTALLING
THE QUARTZ THIMBLE and UV LAMP.
Cotton or powder free nitrile gloves should be worn whenever handling the UV lamp or quartz in
order to prevent finger print marking, which will detrimentally impact UV intensity.
The servicing of this UV reactor should only be carried out by a qualified service technician. Failure to
do so will result in the warranty being void. Warranty is also voided should non UV Guard spare parts
be used.
3.1 Servicing Intervals
Refer to the below routine servicing interval table. It is vital that these actions are performed at the
designated periods to ensure your UV system is disinfecting suciently.
Spare part Action Interval
UV lamp Replaced 12 months or 9,000 hours
Quartz thimble Cleaned *12 months - minimum
Replaced 24 months
O ring Replaced 12 months
*It is recommended that a required quartz thimble cleaning interval is established as each
installation is dierent, especially when treating rainwater. This is done by checking the condition of
the quartz thimble at regular intervals until it is dirty and needs to be cleaned. The time it takes for
the quartz thimble to become dirty should then be the cleaning internal in the future.

14
SLT-Series™
3.2 Servicing the Quartz Thimble
•Switch o main power supply to the UV disinfection reactor.
•Isolate the water supply to the UV reactor. Release pressure and drain water within the
reactor.
•For the SLT12, unscrew the securing screw at the side of the plastic cap. For all other models,
remove the three screws that secure the electrical cap to the sealing nut. Slide the lamp out
enough to be able to remove the four pin plug.
•Disconnect the four pin plug from the end of the UV lamp. Remove the UV lamp from the
reactor and place in a safe place.
•Unscrew the sealing nut in an anti-clockwise direction and carefully remove it from reactor.
Take care with single ended chambers with spring quartz support, as the spring will suddenly
push the quartz out of the chamber when the sealing nut becomes disengaged from the
thread on the chamber. Take care to hold on to the quartz thimble as it may come out of the
reactor at the same time. Remove the sealing nut from the quartz thimble and store in a safe
place. You can then remove the quartz thimble from the reactor.
•If the thimble is due for a clean, wipe it down with a cleansing cream or similar and then wash
down with water. It may be necessary to scrape o the remnants of the old O ring with a sharp
knife. Repeat this step until the quartz thimble is clean, then wipe down the quartz thimble
with a alcohol wipe or soft cloth/ tissue that has been soaked in methylated spirits, then dry it.
(take care not to leave any marks on the quartz). If the quartz thimble is dirty to the point of it
not being able to be cleaned, replace it.
•Re-assemble the reactor as described in the ‘assembly’ section.
3.3 Servicing the UV Lamp
•Switch o the mains power to the UV disinfection unit. The lamp may be hot so allow 10
minutes for the lamp to cool down before handling it.
•Remove the three screws that hold the end cap in place on the end of the sealing nut. The UV
lamp will be attached to the lead that goes through the end cap.
•Slide the UV lamp out just enough so that you are able to get a firm hold on it, you will then be
able to remove the four pin plug that is connected to the end of the UV lamp.
•After the four pin plug has been removed, you can then remove the UV lamp from the reactor.
•Reinstall UV lamp as described in the ‘assembly’ section.

3.4 Servicing and Operating UV Controllers
3.4.1 40044 and 40089 Controllers
The 40044 and 40089 controllers are for indoor use only (require
shelter). They have lamp on/o LEDs and a lamp fail audible
alarm.
Under normal operation, the green LED will be on.
When there is a fault with the UV lamp the red LED will be on
and the controller will sound an alarm. If no LEDs are on but
there is power to the controller, the controller may be faulty and
will need to be replaced.
3.4.1 40051 and 40091 Controllers
The 40051 and 40091 controllers are designed to be installed in
the weather but away from direct sunlight. They have lamp on/
o LEDs.
Under normal operation, the green LED will be on. When there is
a fault with the UV lamp or controller the red LED will be on.
If no LEDs are on but there is power to the controller, the
controller may be faulty and will need to be replaced.
3.4.3 40050, 40090, 40185 and 40173 Controllers
1. Normal Operation:-
When the 40050 or the 40090 power supplies are properly
installed, connected to a UV lamp ,switched on and operating
normally, the red digital screen will initially display ‘365’
indicating 365 days of rated lamp life remaining. The green LED
will also be illuminated indicating the UV lamp is operating.
The red digital display will decrease each day until the screen
reaches ‘0’ and the end of lamp life alarm is activated.

16
SLT-Series™
2. Display Options:-
There is a single “S” button operation for viewing options and re-setting the unit. Under normal
operating conditions the screen can display lamp life left in days (365 0 days) or ballast operating
time in days (0 9999 days). The default display is the remaining lamp life in days (365 0 days).
To view ballast operating time, press the “S” button for less than 2 seconds. The LED display will show
ballast operating time (0 9999 days) for 10 seconds then return to displaying the remaining lamp
life (365 0 days). Pressing the “S” button while the ballast operating time is displayed will return the
display immediately to the remaining lamp life before reaching the end of 10 seconds.
3. Lamp Failure:-
If the UV lamp fails the buzzer will sound on and o at 1 second intervals, the red LED will be
illuminated and the remaining lamp life will stop counting down. These features will remain until the
lamp is replaced and the ballast re-set. The ballast operating days will continue to count up while
there is power to the ballast.
4. End Of Lamp Life Alarm:-
When lamp life reaches 0 the display will show “A3”, the red LED will flash and the buzzer will sound on
for 1 second and o for 5 seconds.
5. Deferring End Of Lamp Life Alarm:-
The end of lamp life alarm can be deferred four times for a period of 7 days, to allow time to order and
replace the old lamp with a new lamp. To defer the alarm, press and hold the “S” button for 5 seconds
until the screen displays “dELy” then release the button and the lamp life will be re-set to 7 days and
there will be no audible alarm but the Red Light will be flashing and the “A3” will be displayed. The
ballast will count down from 7 to 0 days and the alarm buzzer will start again. This deferring of the end
of lamp life alarm can be done 4 times. After the fourth time the buzzer cannot be stopped until the
lamp is replaced and the lamp life re-set.
6. Lamp Life Re-setting:-
When a new lamp is installed in the UV unit the ballast should be re-set to indicate 365 days lamp life
remaining. To do this the “S” button should be pressed and held for 10 seconds, when the display will
show “rSEt”. Keep pressing for at least another 4 seconds after the LED digits go to 365 and the buzzer
sounds once, then release the “S” button and the ballast will be re-set and operating normally. So in
total the “S” button needs to be held down for at least 14 seconds to re-set the lamp life.
7. Ballast Failure:-
If there is power to the ballast but there is no digital display and neither of the LEDs are illuminated
then the ballast has failed and needs to be replaced.
