PERFORMANCE
CONSIDERATIONS
The performance of the UVD320S UV disinfection chamber has been
third party validated using accepted bio-assay techniques. The
UVD320S is equipped with both visible and audio lamp failure alarms.
For your safety, it is necessary that you determine that the audio
alarm can be heard where you use the water treated by the unit. It is
possible to operate the unit with the lamp disconnected which will
allow you to validate the adequacy of the audio alarm function in your
installation. The UV power source used with the UVD320S is capable
of controlling a solenoid valve which can shut off the water flow and
protect against using untreated water in case the UV power source
looses power for any reason or the lamp fails prematurely. The use of
the optional solenoid valve is highly recommended. In order to
optimize disinfection performance, you must only use the unit with
water that meets the minimum standard and replace the UV lamp at
recommended intervals. Failure to follow these guidelines will result in
reduced disinfection performance.
UV RADIATION HAZARD
NEVER OPERATE UV LAMP OUTSIDE OF THE UV
DISINFECTION CHAMBER – EXPOSURE TO UV LIGHT
CAN RESULT IN EXTREME BURNING OF SKIN AND EYES
Safety instructions – Please read
carefully
Danger: Do not plug the unit in if any of the external surfaces or
electrical parts is wet. Condensation on the disinfection chamber is
normal.
Danger: To avoid possible electric shock, special care should be
taken since water may be present near electrical equipment. Unless
referred to in these instructions, do not attempt repairs yourself.
Contact the manufacturer for service advice.
Danger: Do not operate this system if it has a damaged electrical cord
or plug, is malfunctioning, or has been dropped or damaged in any
way.
Caution: Do not use this unit for anything other than its intended
potable water application. The use of attachments not recommended,
approved or sold by the manufacturer/distributor may result in an
unsafe condition.
Caution: Before any cleaning or maintenance, always unplug the unit.
Caution: Protect your unit from freezing. Drain all water from the unit
if freezing temperatures exist.
WATER QUALITY
Your UV disinfection system requires clean water for optimum
performance. You should only operate your unit if the source water
meets the following standards.
INSTALLATION CAUTIONS
nConnect your UV unit to a grounded (3 pronged)
receptacle (120V, 60HZ) (a GFI is highly recommended) and ensure
that the lamp connector ground wire is connected to the ground stud
on the top of the reactor vessel. Note: Power source for applications
outside of North America must match requirements of the unit (eg.
240V, 50Hz).
oUV Dynamics disinfection devices are designed to be installed on
the cold water line only.
pThe unit must be installed vertically with the lamp connector
pointing upwards – the water source should only be connected to the
inlet port on the bottom of the unit. CAUTION: reversing the flow
direction by connecting the water source to the side mounted output
port could result in reduced disinfection performance and improper
operation of the flow regulator.
qInstall your UV Dynamics disinfection system indoors in a protected
area where the temperature does not fall below 4°C. (40°F) and the
humidity level is low (to prevent condensation on the chamber). This
unit functions ideally in a temperature range from 9°C - 29°C. (49 –
85F)

Installation Procedure
The UV disinfection system should be the last step of your water
treatment system. Choose a location for installation with a close
electrical outlet. Note the direction of water flow in the supply line.
Refer to the plumbing diagram and check that you have all necessary
fittings for installation. Note: A minimum of 17” clearance at lamp
cord end of the chamber will allow most maintenance procedures to
be accomplished without removing the disinfection chamber from its
mounting bracket.
nShut off the main water supply valve.
oMount the unit to the wall using the mounting bracket provided.
Mount ballast on the bracket beside the chamber.
pInstall new plumbing as per diagram. Note: When installing the 5
micron pre-filter, make sure the flow arrows on them point in the same
direction as the water flow. WARNING: if soldering, do not allow
heat near plastic threads or fittings.
qPlace the thinner “O” ring into the groove of the gland nut holder,
and the thicker “O” ring on the open end of the quartz sleeve. Then
push the quartz sleeve into the gland nut until the sleeve touches the
top.
rPlace the quartz sleeve into the opening at the top of the UV
chamber and screw it into place.
sPlace the lamp spring and the lamp into the quartz sleeve and,
holding the top of the lamp, attach lamp to the lamp connector. Push
the lamp connector down snugly into the gland nut.
WARNING: do not over tighten as plastic threads are easily
damaged
tRemove the nut from the ground stud at the top of the unit. Next,
place the ground wire (green wire with yellow stripe) over the stud and
re-install nut and tighten. FAILURE TO GROUND CHAMBER MAY
RESULT IN ERRATIC UV SENSOR BEHAVIOUR
uInstall UV detector probe. The probe must be tightened down
completely to insure accurate calibration. If the probe cannot be hand
tightened, use locking pliers with minimum pressure required to grip
the probe body securely to finish installation. Connect UV detector
probe plug into port labeled UV sensor on the UV power source.
Caution – Do not over tighten.
vOpen the valves on either side of the disinfection chamber. Check
for leaks. Open supply valve slowly and bleed air from system.
wConnect UV power source to AC line. UV power source audio
alarm will sound three times before igniting the lamp.
Your UV Dynamics disinfection system is now ready for service.
Before service begins, all household plumbing lines should be
chemically disinfected.
DISINFECTION PROCEDURE
THE FOLLOWING DISINFECTION PROCEDURE IS GENERALLY
ACCEPTED AS BEING SUITABLE FOR THE DISINFECTION OF
PLUMBING SYSTEMS KNOWN TO BE CONTAMINATED.
IF YOU ARE UNCERTAIN ABOUT THE EFICCACY OF THIS
PROCEDURE YOU ARE ADVISED TO CONTACT THE LOCAL
HEALTH AUTHORITY RESPONSIBLE FOR WATER SAFETY.
The UV disinfection process takes place only in the UV disinfection
chamber and the process provides no residual disinfection capability,
therefore it is necessary to chemically disinfect the entire
plumbing system before using water treated by the UV system.
nThe disinfection of the plumbing system is most readily
accomplished by removing the 5 micron sediment filter cartridge and
adding 250ml - 500ml (1 –2 cups) of standard 5.25% concentration
un-scented chlorine bleach to the empty filter housing and
re-installing.
oVerify that the UV disinfection unit is connected to the AC supply
voltage and operating properly.
pOperate all faucets, fixtures and appliances until you clearly
smell chlorine and shut off. This includes shower heads, outside taps,
dishwashers, laundry equipment and any appliance connected to the
plumbing system.
qLeave the bleach solution for 30 minutes.
rRe-install the sediment filter cartridge and thoroughly flush the
system at all fixtures and appliances connected to the system.
Note: The introduction of a chlorine disinfection solution to a hot water
heater that has been used with untreated hard water or water with
excessive iron, manganese or other organic contaminants may lead to
oxidization of these materials. If you feel that these conditions may
apply to your installation, a thorough flushing of the hot water tank
should be undertaken to eliminate the oxidized material from the
system.
UV POWER SOURCE FEATURES
The micro-processor controlled UV power source supplied with the
UVD320S has both audio and visual alarm indicators to validate lamp
operation and an integral annual lamp change reminder timer.
A two digit seven segment display is provided to display relative UV
level, lamp life remaining (when timer button is pressed) and various
error codes to aid in system diagnostics. If the relative UV level falls
below 50%, the unit goes into the low UV alarm mode and the
solenoid valve, if installed, will be de-activated.
UV power source initialization sequence: When AC power is
applied to the UV power source the lamp is ignited, as indicated by
the green lamp-on LED, after which a self test of the annual lamp
change reminder timer LED and alarm buzzer consisting of three
buzzer beeps and three red timer LED flashes. The two digit display
indicates the relative UV level. If a solenoid is connected to the UV
power source, it will activate when the UV level reaches 50%.
Normal Operation: During normal operation, the green lamp-on LED
is illuminated and the two digit display indicates the relative UV
intensity.
Lamp failure: When the UV power source detects a lamp failure or
enters the auto shut down mode due to abnormal operating
conditions, the alarm buzzer sounds and the green lamp-on LED is
extinguished. If connected, the solenoid valve will terminate the water
flow.
Lamp timer operation: The annual lamp change reminder timer will
run for approximately one full year. At the end of the one year period
the lamp change reminder timer will flash and the buzzer will sound.
The flashing LED indicates that the timer function is in the 28 day
grace period. Pushing the timer button during this grace period will
silence the buzzer for a seven day period but the LED will continue to
flash. The buzzer reset can be activated a maximum of four times
during the 28 day grace period. Under no circumstance does the
grace period exceed 28 days. At the expiry of the 28 day grace period
the UV power source indicates the lamp change alarm mode by
illuminating the red timer LED continuously, displaying the error code
E5 and sounding the buzzer. Note: The UV lamp is not shut down in
this alarm mode and the solenoid valve drive is not disabled.

Time remaining: When the lamp change reminder timer is not in the
grace period or lamp change alarm mode, the number of months of
lamp life remaining will be displayed on the two digit display by
pressing the timer push button. Activating this feature also causes the
red timer LED to flash, this is normal.
Note: The UV power source is designed to shut down if the AC input
voltage is outside of operating limits. When a lamp failure alarm is
active the unit should be unplugged from the AC power source for
fifteen seconds and then reconnected to the AC power source. If the
failure was due to out of limit AC power, the unit will re-ignite the lamp
and operate normally.
Solenoid Valve Output: The UV power source is capable of directly
powering a solenoid valve which will shut off water flow during lamp
failure alarm conditions.
Low UV Intensity: If the output of the UV detection system falls below
50%, a low UV alarm will be initiated and error code E1 will be
displayed. If a solenoid valve is installed it will be deactivated to stop
the flow of water.
Solenoid Override: The UV power source has a solenoid override
feature to enable emergency water flow when the system has entered
a low UV alarm state. Pressing the button during error code E1 will
initiate the override, which is active for six minutes, but can be reset
indefinitely. The solenoid override feature will not function if the lamp
has failed. Displays error code E4
CAUTION: The water treated by the unit will not
be properly disinfected when the solenoid
override is in operation.
UV Sensor Error: If the UV sensor is not connected to the UV power
source or if the sensor is malfunctioning, the sensor error code E3 will
be displayed. Verify that the sensor plug is fully inserted into the UV
power source before replacing the UV Detector.
UV Power Source ERROR codes
E1 – Low UV Intensity
E3 – Sensor Error
E4 – Solenoid Override Active
E5 – Change Lamp
Operating and Maintenance
Your UV system is on continuously during normal use.
After periods of not using your water supply exceeding 2-3 days, it is
recommended to open all faucets and flush your plumbing lines for a
minute or two.
Caution: Protect your unit from freezing. Drain all water from the unit
if freezing temperatures exist.
Ultraviolet lamp replacement: The ultraviolet lamp located inside the
chamber will operate effectively, round the clock, for approximately
one year. The lamp will light longer than that. However, the UV light
penetration may fall below the prescribed safety level. Therefore,
annual lamp replacement is necessary regardless of apparent
condition.
Replacing the UV lamp and cleaning the quartz
sleeve
Note: Do not touch the lamp or the quartz sleeve with your fingers.
Handle by ends only or wear soft gloves.
nUnplug the system from the electrical outlet and turn off all water
supplies to the unit.
oCarefully extract the lamp connector from the sleeve gland nut
assembly to expose just the top of the lamp. While holding the lamp
base firmly, remove the lamp power connector. Caution: lamp base
can be very hot – be careful not to drop lamp into quartz sleeve as it is
easily broken.
pCarefully slide the UV lamp out of the quartz sleeve and discard
according to local disposal regulations
qRemove the quartz sleeve by loosening the gland nut and carefully
extracting it from unit. Caution: The quartz sleeve is fragile and is
easily chipped or broken – use care when removing or installing.
rClean the quartz sleeve with a vinegar solution or a readily
available scale removal product (Limeaway, CLR etc.)
sRe-install the quartz sleeve – replace “O” ring if it appears
damaged.
tInstall new lamp by reversing procedure described in step 2 above.
uSlowly open water supply valve and purge air from system – verify
that there are no leaks before reconnecting to AC power.
RESETTING THE LAMP CHANGE TIMER
nThe lamp change reminder timer is reset by disconnecting the UV
power source from the AC supply, waiting for fifteen seconds and
reconnecting to the AC supply with the timer button depressed. The
UV power source will emit a solid three second beep indicating that
the reset was successful.
It is not possible to reset the lamp change timer unless the timer
is in the grace or lamp change alarm mode. If you need to reset
the lamp change reminder timer prior to the full one year time
period expiring due to premature lamp failure, there are special
instructions included with all replacement lamps describing the
necessary procedure.
