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 23” 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.
n
Shut off the main water supply valve.
o
Mount the unit to the wall using the mounting bracket provided.
Mount ballast on the bracket beside the chamber.
p
Install 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.
q
Place 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.
r
Place the quartz sleeve into the opening at the top of the UV
chamber and screw it into place.
s
Place 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 and tighten.
WARNING: do not over tighten as plastic threads are easily
damaged
t
Remove 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.
u
Open the valves on either side of the disinfection chamber. Check
for leaks. Open supply valve slowly and bleed air from system.
v
Connect 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.
n
The 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.
o
Verify that the UV disinfection unit is connected to the AC supply
voltage and operating properly.
p
Operate
all faucets, fixtures and appliances
until you clearly
smell chlorine and shut off.
This includes showerheads, outside taps,
dishwashers, laundry equipment and any appliance connected to the
plumbing system.
q
Leave the bleach solution for 30 minutes.
r
Re-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 microprocessor controlled UV power source supplied with the
UVD400 has both audio and visual alarm indicators to indicate the
lamp operation and an integral annual lamp change reminder timer.
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. If a solenoid is
connected to the UV power source it will activate on completion of the
self-test sequence.
Normal Operation:
During normal operation only the green lamp-on
LED is illuminated.
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 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 can be determined by pressing the timer button
and counting the number of red timer LED flashes.
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 you should unplug the unit from the AC power source, wait for
fifteen seconds and then reconnect to the AC power source. If the
